## Detailed walkthrough ### `00:00` Documents as the Missing Artifacts of Human Knowledge
Reducto co-founder and CEO Adit Abraham recalls founding the company with his co-founder Ronik in 2023. At the time, frontier models suffered from extremely constrained context windows, making memory the most pressing, obvious pain point. However, their trajectory shifted almost immediately: “The day we got into YC, we told that we were going to pivot.” Although the retroactive rationale sounds far more lucid than it was at the moment, it centered on a core realization: as AI agents take over human work, they inevitably have to interface with documents. Across legal, finance, healthcare, and insurance, human knowledge is cataloged in PDFs and spreadsheets.
```mermaid flowchart LR accTitle: Evolution of Document Processing accDescr: Three epochs moving from file drivers to OCR templating and finally to modern multimodal understanding. subgraph Epoch1["1990s: Driver Era"] E1["File processing & printer drivers"] end subgraph Epoch2["2000s-2010s: Template IDP"] E2["Pixel-level templates & rigid OCR rules"] end subgraph Epoch3["2023+: Agentic Era"] E3["Vision-Language Models with human-like reasoning"] end Epoch1 --> Epoch2 --> Epoch3 ```
When building AI agents for high-stakes workflows like patient record extraction, accuracy is not a casual concern. A mistake on a checkbox is not a minor software glitch—it directly alters clinical decisions and patient outcomes. Adit notes that while the historical drive was serendipitous—meeting early vertical AI companies struggling with document infrastructure while coming from a computer vision research background—the mission quickly spiraled into creating the connective tissue between synthetic intelligence and human knowledge: “Documents to us are almost these abstractions and artifacts of human work.”
- Reducto was founded in 2023, initially targeting LLM memory constraints before pivoting upon admission to Y Combinator. - The company's initial insight came from recognizing that early AI-native software builders consistently stalled out on messy document processing pipelines.
`03:32` The Shift from Legacy OCR to Vision-Language Models
Reflecting on the evolution of document tech, Adit jokes that he has met engineers who have worked on PDF processing longer than he has been alive. The PDF was designed in the 1990s as a print driver specification meant solely to faithfully render characters onto physical paper, not to encode structured data. This led to distinct technology epochs: 1. File format processing and printer drivers. 2. Template-based intelligent document processing (IDP) and OCR, where engineers drew rigid pixel-level bounding boxes around forms like W-2s and post-processed raw text.
That approach collapses under variability. In the modern era, user expectations have fundamentally shifted: “Nobody thinks about complexity when they upload a document to ChatGPT. You just expect it to work.” Modern vision-language models (VLMs) fundamentally change the paradigm because they reason over layout and contents visually, treating documents as 9x11-inch image grids. This makes it possible to understand multi-column reading orders, merged table cells, and two-dimensional data without hardcoded templates.
Early on, Reducto balanced trade-offs across latency, cost, and determinism by running traditional computer vision algorithms to anchor document structure and invoking VLMs as an intelligent correction loop.
`06:08` Training Reducto's R1 Model for Document Distribution Corners
To transcend the accuracy, speed, and cost trade-offs of combining disparate models, Reducto transitioned to post-training their own foundation model, dubbed R1. Rather than relying on generic off-the-shelf multimodal endpoints, R1 unifies structural segmentation, bounding box detection, and text reading into a single end-to-end model.
Adit explains that R1 was not built on a single quarterly breakthrough, but developed out of extensive production error telemetry gathered from enterprise customers handling difficult distributions:
| Challenge Type | Document Example | Model Failure Mode / Engineering Solution | |:--- |:--- |:--- | | **Repetitive Formatting** | Dotted lines (`.....`) separating text fields | Standard VLMs fall into infinite repetition loops; mitigated via specialized post-training data. | | **Multi-page Continuity** | Financial tables spanning across page boundaries | Scanning skew creates mismatched columns; resolved via cross-page structural stitching pipelines. | | **Ultra-dense Layouts** | Technical blueprints, architectural schematics, CAD exports | Text and lines exceed native vision resolution; addressed with human-like, multi-scale patchwork zoom pipelines. |
Adit emphasizes that solving these problems requires deep engineering across the entire training pipeline: “We've also been fortunate to work with some of the hardest distributions of data. We work with the largest enterprises, the leading AI native companies, and they've helped us understand the corner cases of where different types of models fail.”
`08:52` Beyond Parsing: The Compounding Error Problem in Multi-Step Workflows
When evaluating benchmarks, Adit points out that single-page parsing accuracy in the high 90s is already achievable on ordinary pages—excluding extreme outliers like illegible doctor handwriting. However, automated document agents cannot survive on single-page parsing metrics alone. Real-world workflows, such as processing an entire loan application packet, entail an end-to-end multi-step assembly line: 1. Splitting complex, multi-document packet PDFs into logical sub-files. 2. Parsing and structuring messy page data. 3. Extracting exact, typed schema fields. 4. Programmatically modifying and writing back out to output forms.
In multi-file, multi-step environments, acceptable single-page metrics quickly degrade into overall system failure: “If you're taking in a dozen files, you can't have 90% on individual pages because those mistakes compound, right?” To unlock full end-to-end agentic automation without humans in the loop, error rates must be driven down across every single sub-step of the document stack.
`10:00` Surpassing Human Ground Truth with Deep Extract
Reducto has expanded beyond model development to release orchestration harnesses around their extraction pipelines. Adit Abraham highlights Deep Extract as an inflection point where software agents consistently outperform manual human review on complex, structured extraction tasks. In many production benchmarks, Reducto discovered that human-annotated ground-truth datasets were riddled with baseline errors that clients previously failed to notice simply because the human work was assumed to be the objective standard.
Humans get fatigued, skip lines, drop entire rows, or lazily fill in only portions of wide tables. By deploying targeted extraction harnesses, agents systematically eradicate those omissions. Adit Abraham explains this dynamic directly: “We find situations where human annotated ground truth has a lot of errors that they wouldn't have otherwise known because it's your ground truth. What is the comparison point? But when you think about it, humans make all sorts of mistakes.”
`10:48` Crossing Seven Billion Pages: The Economics of High-Volume Ingestion
As extraction and parsing costs collapse to Reducto’s list price of one cent per page, Jennifer Li asks how dropping prices unlock new categories of automated workloads. Abraham notes that early enterprise AI was artificially constrained to simple search chatbots interrogating narrow, static repositories. When agents are equipped with low-latency, low-cost document parsing, they can actively explore corporate knowledge bases, pull uncurated files from the open web, and reason over vast corpuses without engineering teams worrying about budget blowouts.
On the morning of the recording, Reducto crossed the milestone of seven billion total pages processed, routinely chewing through billions of pages each month. While one cent per page is the standard list price, the team is actively optimizing pipeline economics and infrastructure to support enterprise customers who want to ingest tens of billions of pages. Jennifer Li jokes about a past tweet marking their first billion pages, and Abraham confidently predicts that by the time the podcast airs in late October, they will cross eight billion, consistently shattering their internal weekly volume records.
- **Milestone:** Crossed 7 billion total pages processed on the morning of recording; on track to exceed 8 billion by late October. - **Current throughput:** Billions of pages processed every month. - **Pricing:** $0.01 per page list price, with volume discounts engineered for tens-of-billions scale. - **Strategic objective:** Every single document page routed to an LLM must pass through Reducto first as an invisible, frictionless ingestion layer.
`12:20` Driving Enterprise Growth: From Legal AI to Wall Street Alpha
Early document processing adoption was dominated by AI-native pioneers like Harvey (in legal tech) and Rogo (in finance), which primarily built search, retrieval, and information synthesis tools. Recently, Reducto’s customer base expanded significantly into major private equity firms, the world’s largest hedge funds, and enterprise tech companies. These institutions are shifting from informational chatbots to autonomous agents executing real operational tasks.
For high-frequency finance, extracting signals from unstructured filings, messy prospectuses, and earnings attachments faster than the rest of the market translates into measurable competitive advantage. Adit Abraham underscores this shift: “And so if you can be faster and more robust and gathering all the signals that are available, that's alpha. And those are sorts of things that we're starting to see more and more.”
`13:40` Workflow Harnesses, Multi-Endpoint Pipelines, and Document Reconciliation
As enterprise implementations matured, Reducto observed clients chaining multiple endpoints together, forcing the company to build comprehensive harnesses that handle evaluation, human review, and workflow composition. Production documents present messy, real-world edge cases: corporate systems harbor duplicate versions of redlined term sheets, conflicting contracts, and files vaguely tagged "final" without clean lineage.
To resolve these contradictions, Reducto’s harness provides granular traceability. Instead of simply asserting an extracted fact and citing a raw document, the pipeline anchors the answer to the exact individual word on the page. By mapping evidence word-for-word across multiple conflicting versions, an agent can reconcile discrepancies and establish ground truth.

`14:48` The Code Gen Playbook vs. High-Stakes Professional Services
Abraham contrasts the astronomical rise of AI code generation with the slower commercialization of document-heavy professional services like healthcare, insurance, law, and corporate finance. In early 2023, code generation was largely viewed as trivial code completion; the founders of Cursor famously shaved their heads to celebrate reaching $1 million in ARR. Today, multiple AI coding companies command hundreds of millions or billions in ARR, yet enterprise document workflows have not seen an equivalent scale breakout.
``` AI Coding Evolution: [Early 2023: Simple Code Completion] ---> [Founders shaved heads for $1M ARR] ---> [Present: $1B+ ARR Enterprise Market]
Professional Services Reality: [Massive Paper Trails in Healthcare, Law, Insurance] ---> [Bottlenecked by high consequence errors, not raw intelligence] ```
Li and Abraham debate whether this gap stems from cultural inertia or technical hurdles. Developers love automating their own workflows and have an appetite for experimental "toys." More importantly, the stakes are asymmetric: if a developer "vibe codes" an application and introduces bugs, they can trivially roll back a git pull request. In contrast, misinterpreting a clinical document, missing a healthcare claim restriction, or hallucinating a contract clause carries catastrophic financial, legal, and human consequences. Adit Abraham emphasizes that adoption requires rock-solid confidence mechanisms: “If you vibe code something and it's filled with bugs, you get to roll back your PR in a way that is not true if you're making decisions in healthcare. There are stakes there that are very, very real.”
`16:42` Beyond Parsing: Headless Office Tooling and Native Document Editing
Looking ahead, Reducto is expanding beyond passive read-only ingestion into active, bidirectional document editing. While models excel at translating freeform text, applying those edits cleanly back into native file structures (such as Microsoft Office files) remains surprisingly difficult for agent architectures. A task like document localization highlights this friction: while converting text into Arabic is simple for a frontier model, formatting, placing, and preserving the surrounding layout in a production Word or Excel document breaks existing tools.
Reducto is releasing document-editing capabilities, starting with a ChatGPT plugin designed to function like a headless Microsoft Word that AI agents can programmatically manipulate. Beyond editing, the company is rolling out resilient observability, evaluation frameworks, and schema-optimization tooling to let enterprise customers fine-tune document pipelines against their proprietary enterprise contexts.
- **Upcoming releases:** Headless Microsoft Word document-editing plugin for ChatGPT and programmatic editing APIs. - **Focus areas:** Document localization, schema optimization, continuous evaluation, and enterprise pipeline observability.
`18:25` Why Frontier Labs Won’t Solve the Document Layer
When Li asks why general-purpose frontier model labs—despite their multimodality pushes—won't simply solve this problem themselves, Abraham explains that the document layer involves deeply unglamorous engineering tangential to frontier reasoning intelligence. Frontier labs prioritize core reasoning benchmarks, while real-world documents present a bottomless pit of bizarre edge cases that take years of dedicated infrastructure to support.
Abraham notes that even after analyzing more PDFs than almost anyone, he still routinely encounters mind-boggling file structures: PDFs packaged inside embedded folders that sit within other PDFs, complex layer masks, or legacy Word files that have zero reliable open-source rendering engines. Frontier model labs have little incentive to maintain the sprawling parser matrices and specialized vision pipelines needed to reliably read these legacy formats. Adit Abraham captures this dynamic bluntly: “Yeah, a lot of the work that we do is kind of tangential to intelligence. Like we're not trying to compete with the labs on reasoning quality. And I think one of the things that's underappreciated is how deep the range of problems gets, like even after probably looking at more PDFs than most humans, I still find corner cases that we didn't expect.”
`20:00` Specialized Infrastructure vs. Frontier Model Generalization
Standard open-source conversion libraries such as LibreOffice consistently break down when attempting to faithfully render complex layouts. While frontier research labs have the technical capability to build bespoke parsing tools, Adit Abraham observes that their capital and talent are directed toward an entirely different mandate: racing to build general artificial superintelligence. Reducto operates deliberately on the infrastructure layer surrounding those models, focusing exclusively on document understanding. Generic foundation models must maintain vision encoders versatile enough to transform a casual smartphone selfie into a Studio Ghibli animation; by contrast, Reducto aggressively constrains its problem surface to business documents.
This domain specialization translates directly into cost and throughput advantages for enterprise-scale workloads. When an organization processes millions of pages, raw accuracy is meaningless if latency and inference costs make production unviable. Jennifer Li highlights a common industry misconception: developers assume document extraction can be solved with a simple "one-shot" call to a frontier model. In practice, enterprise extraction requires a multi-stage pipeline that decomposes layout, unpacks formatting, and preserves structural relationships before deploying high-capacity models only for the critical last mile.
Adit Abraham underlines the strategic value of this narrow focus: “The fact that we can constrain the set of problems that we need to be good at is a big part of why we're able to be ahead.” He emphasizes that when enterprises operate at massive scale, specialized tooling fundamentally changes the economics: “We are able to be orders of magnitude more aggressive on price than a frontier model at a comparable accuracy profile And that makes a huge difference on when it makes sense to use something”
- Reducto focuses on delivering frontier-level output quality (such as Astra-level performance) at a fraction of the cost and latency of generalized foundation models. - Enterprise document processing cannot rely on a single brute-force prompt; it requires structural decomposition, region extraction, and targeted downstream processing.

`22:15` The Silent Drop Failure Mode and the "Deep Extract" Architecture
Evaluating long-document extraction reveals a stark divergence between frontier models and specialized parsers. In an independent benchmark conducted in partnership with micro1, frontier models demonstrated high precision—meaning that whenever they chose to extract a value, the output was generally accurate. However, their primary failure mode was recall: across lengthy documents, frontier models silently dropped rows, tables, or line items. In mission-critical production environments, these silent omissions are catastrophic because they trigger no system warnings.
```mermaid flowchart TD accTitle: Reducto Deep Extract Verification Architecture accDescr: Pipeline showing document decomposition, candidate extraction, and programmatic validation.
subgraph Ingestion["Document Decomposition"] Doc["Complex Document / Multi-page PDF"] Split["Splitting & Region Identification"] Doc --> Split end
subgraph Extraction["Model-Agnostic Extraction"] Model["Extraction Engine"] Split --> Model Candidate["Candidate Extracted Data"] Model --> Candidate end
subgraph Verification["Self-Review & Deterministic Checks"] Agent["Parent Review Agent"] Rules["Validation Rules (e.g., Sum Line Items)"] Candidate --> Agent Agent <--> Rules Verify{"Balanced & Complete?"} Agent --> Verify end
Verify -- "Yes" --> Output["Validated Output"] Verify -- "No (Discrepancy)" --> Model ```
To achieve near-perfect recall without hallucination, Reducto engineered its "Deep Extract" harness. Rather than relying on a single model run, the architecture uses a model-agnostic harness equipped with programmatic tools and validation rules. For example, when processing a complex invoice, a supervisor agent validates whether the extracted itemized entries sum up to the listed invoice total. If the math fails to balance, the agent loops back to inspect the specific document region and double-checks the missing line items.
When discussing how teams evaluate such architectures, Adit cautions against relying on public marketing benchmarks. He explains that overly rigid evaluation rubrics frequently penalize systems for formatting variations that represent the exact same source data faithfully. Adit Abraham reflects on the state of industry metrics: “One of the unfortunate things about the AI industry, and I'm not trying to absolve Reducto of this, I think this is just a general thing, is benchmarks have become marketing over time.”
- Frontier models struggle primarily with recall on long-context extractions, silently dropping data without throwing runtime exceptions. - Reducto’s Deep Extract harness couples LLMs with programmatic checks (such as arithmetic validation across tables) to trigger automatic re-inspection loops. - Public benchmarks frequently incentivize overfitting or introduce arbitrary metric rules that fail to reflect real-world enterprise utility.
---
`24:45` Fragile Public Benchmarks and Flawed Golden Datasets
Many widely publicized AI document benchmarks prove remarkably fragile under basic stress testing. Adit shares that Reducto examined a prominent public benchmark and discovered that minor perturbations—such as introducing a single-degree tilt or a modest Gaussian blur to the input page—caused the benchmark creator's own system to suffer severe performance degradation, while third-party parsers maintained consistent accuracy. Because typical enterprise buyers rarely run adversarial stress tests, published leaderboards often give a distorted impression of robustness.
Consequently, Reducto advises organizations to bypass public benchmarks and evaluate vendors using an LLM-as-a-judge setup tailored to their specific document distribution. However, enterprise "golden datasets" carry their own hidden failure modes. When human annotators compile ground-truth data, they frequently suffer from fatigue and miss small details. Conversely, when enterprises generate evals using language models, cost-cutting often leads them to employ cheaper models like Claude 3.5 Sonnet instead of Claude 3 Opus, baking subtle hallucinations and missing values directly into their evaluation baselines.
Adit Abraham notes that rigid scoring rules often backfire during evaluation: “It's generally a mistake to have really strict rules in your benchmarking, for example, because you could represent the same information faithfully two different ways and you don't want to penalize that.” He emphasizes that Reducto routinely audits a client’s evaluation dataset before running bake-offs: “I find that it's increasingly common for people to have at least some form of an eval, but it's really, really hard to make sure that the eval holds.”
- Perturbation testing (e.g., a one-degree tilt or Gaussian blur) exposes whether a benchmark is genuinely resilient or merely overfitted to clean scans. - Human-curated ground truth datasets frequently suffer from dropped information, while synthetic datasets generated by smaller models incorporate extraction errors. - Setting up a trustworthy rubric requires checking the evaluation data itself before running vendor bake-offs.
---
`26:50` Beyond PDFs: Taming Excels and Training Dedicated Chart Agents
Document complexity extends well beyond clean PDF contracts. Reducto supports more than 40 discrete file formats, handling complex media types that cannot simply be serialized into a context window. Large Excel workbooks pose severe challenges: an arbitrary spreadsheet may contain massive sheets, discontinuous data clusters, or multiple tabs that completely overwhelm the spatial reasoning of general LLMs. Instead of feeding raw spreadsheet data directly into a model, Reducto parses and structures the workbook into an intermediate representation optimized specifically for language model comprehension.
Understanding visual assets inside documents requires breaking down complexity in distinct phases: first determining whether a document is difficult, next evaluating the page, and finally isolating high-complexity regions within that page. Financial documents heavily rely on visual time-series assets like line charts and bar graphs. While human analysts immediately identify high-level trends and inflection points, standard vision-language models struggle to extract specific data points from visual axes. To solve this, Reducto developed specialized "chart agents" capable of transcribing raw graphical charts into precise, structured numerical points that agentic workflows can compute over.
Adit Abraham takes pride in the performance of these domain-specific models: “We should pull out the benchmark on that one because it's actually hilarious of how bad other models are.” Ultimately, the goal is total abstraction for the developer, as Adit Abraham concludes: “The best version of Reducto is one where you can kind of abstract away the PDF processing problems, even if the PDFs contain these like sub intricacies along the way.”
- Reducto parses over 40 formats, transforming dense multi-tab spreadsheets into model-optimized structures rather than dumping raw tokens into context. - Document processing complexity unfolds hierarchically: document level, page level, and local sub-region level. - Standard vision models are fickle when reading graphical trendlines, prompting Reducto to train dedicated chart agents that extract discrete numerical values from financial graphs. - Jennifer Li notes that the sheer variety of layout challenges—from multi-tab workbooks to nested tables—represents an effectively unbounded technical challenge for document agents.
`30:00` Reducto's Ambition Beyond Legacy Intelligent Document Processing
Jennifer Li turns the conversation toward long-horizon, end-to-end problem solving, asking what opportunities remain underappreciated in the market as AI evolves into building harnesses and workflows. Adit Abraham explains that immense innovation is taking place across both AI-native startups—citing legal tech company Harvey—and in-house enterprise teams. He wants Reducto to serve as the dependable infrastructure underpinning both ends of that spectrum. This entails not only achieving world-class parsing accuracy, but also tackling heavy underlying plumbing, such as building the infrastructure required to ingest and parse 10 million documents in parallel.
Adit rejects the legacy label of "intelligent document processing" (IDP), arguing that Reducto’s long-term vision is fundamentally different from traditional scanning utilities. As Adit puts it: “We want to be at a place where agents can help augment human work.” Li echoes this by emphasizing that the two foundational inputs to language models are data and compute; by transforming complex physical and digital files into structured data that models can act upon, Reducto unlocks massive downstream value.

`31:37` The High Stakes of Accuracy: Sub-50% OCR Baselines and Healthcare Denials
The conversation shifts to the tangible, human cost of extraction errors and how accuracy directly dictates whether enterprises can trust AI agents. Adit shares a case study of a healthcare customer that runs a clinical search tool helping physicians pull patient histories out of massive physical record packets that are literally measured "in inches in height," sometimes running tens of thousands of pages. In these real-world settings, Adit notes that legacy OCR tools frequently exhibit accuracy rates "sub 50%," forcing systems to rely on crude approximations while overburdened clinicians try to cross-check records.
Adit highlights how a single misread term can cascade into life-altering consequences for patients: “Because the initial pipeline read something as pain instead of chest pain, somebody's claim gets rejected because the doctor searches for, do they have a history of this?” Overworked doctors cannot afford the time to audit raw OCR text. If an AI agent were given full autonomy to adjudicate prior authorizations or coverage determinations off faulty inputs, the entire workflow would collapse.
- **Stack thickness over page counts:** Difficult clinical files are frequently received as physical bundles measured by height in inches rather than standard page counts. - **Legacy OCR failure rates:** In messy real-world medical documentation, traditional OCR engines often sink below 50% accuracy. - **Cascading diagnostic errors:** Missing a single modifier (such as reading "pain" rather than "chest pain") leads search systems to return false negatives, causing doctors to withhold necessary drugs or insurers to deny prior authorization.
`33:38` Systemic Inefficiency: The 80% Medicare Appeal Reversal Rate and Paper Bottlenecks
When Li asks about the current fallback when systems miss critical information, Adit points out that the incumbent status quo is simply rampant human error and bureaucratic failure. Every year, millions of Medicare claims are initially rejected during the prior authorization stage. However, an astonishing statistic reveals the underlying fragility of the process: in 80% of appeals, the initial rejection is overturned. This staggering error rate illustrates how broken early-stage record evaluations are across the board.
Adit notes that this paperwork crisis is not isolated to medicine. The backlogs seen at the United States Citizenship and Immigration Services (USCIS) stem from similar structural bottlenecks. These workflows involve mountains of physical paper, handwritten notes, and photographic evidence that require high-precision human-in-the-loop inspection. If agent infrastructure can lift the constraints around accuracy, latency, and processing costs, frontier models can dismantle these massive backlogs and relieve administrative logjams across society.
> “And one of the craziest stats I learned is that in 80% of appeals, the original decision was overturned, which is... should be shocking because clearly there's some inefficiency in how the decision was originally made.” — Adit Abraham
`35:10` Automating the Rote: Paper Tax Filings, Enterprise Back Offices, and Modern Solutions
Li asks what manual categories of business work should disappear once models can reliably read, evaluate, and edit complex documents. Adit zeroes in on rote data entry as the immediate low-hanging fruit. Despite widespread digitization, massive volumes of critical workflows still rely on human workers manually transcribing physical documents into databases. In the United States, for instance, 16% of tax filers still submit their returns through physical mail, generating weeks of mechanical manual processing.
Adit details how software vendors and enterprise service firms are attacking this friction. In the accounting domain, startups like Basis are pioneering automated workflows. Concurrently, Reducto works directly with large enterprise accounting firms handling specialized government paperwork like Customs and Border Protection forms, as well as business process outsourcing (BPO) firms running enterprise back offices. Freeing these organizations from repetitive transcription allows human judgment to focus on higher-level reasoning. Li and Adit wrap up the conversation on the shared goal of eliminating rote human-in-the-loop grunt work to let companies tackle more ambitious problems.
- **Paper tax filings:** Roughly 16% of American tax filers continue to submit physical paper returns via postal mail. - **Accounting automation:** AI-native platforms like Basis are automating traditional accounting workflows. - **Specialized enterprise forms:** Reducto’s document pipeline is deployed across massive accounting services processing Customs and Border Protection filings, as well as global BPO service providers.

## Video description AI agents can reason over enormous amounts of information, but much of the world’s actual work is still trapped in PDFs, spreadsheets, scans, and other formats that models struggle to reliably understand. Reducto co-founder and CEO Adit Abraham argues that solving this document layer is essential if agents are going to take on consequential work in healthcare, legal, finance, and insurance. Adit joins a16z General Partner Jennifer Li to explain why traditional OCR breaks down on messy real-world documents, how Reducto combines vision-language models with specialized infrastructure to reach high accuracy without sacrificing cost or latency, and why frontier models can silently drop information on long extraction tasks. Reducto now processes billions of pages each month, including its seven billionth page the morning of the recording. They also discuss Reducto’s R1 model, agents that can review and correct their own document extraction, and the company’s push beyond simply reading files toward letting agents reliably work with and edit them. Underneath it all is a higher-stakes problem: when a misread word can affect a healthcare claim or financial decision, getting the input right matters just as much as making the model smarter.
