OpenAI's AI Agent Streamlines Contract Review

Discover how OpenAI uses its own AI to transform tedious legal document processing into searchable data.

OpenAI developed an internal AI agent to automate contract review, turning unstructured legal documents into usable data. This innovation significantly boosts efficiency, allowing finance teams to handle thousands of contracts without proportional staff increases. It also shifts expert focus from manual data entry to critical analysis.

OpenAI's AI Agent Streamlines Contract Review

Key Facts

  • OpenAI developed an internal AI agent to manage its increasing volume of contracts.
  • The agent processes thousands of contracts monthly, a significant increase from hundreds, without proportional headcount growth.
  • It converts diverse contract formats (PDFs, scanned copies, photos) into structured, searchable data.
  • The AI uses retrieval-augmented prompting to reason and highlight non-standard terms for human review.
  • This system has expanded to support procurement, compliance, and month-end close operations.

Why You Care

Ever feel buried under paperwork, wishing a smart assistant could just handle the grunt work? What if an AI could read and understand your complex documents, making them instantly searchable and useful? OpenAI, the company behind ChatGPT, is doing exactly that internally. They’ve built an AI agent to tackle their own growing mountain of contracts. This means faster operations and smarter decisions for your business too.

What Actually Happened

OpenAI faced a common business challenge: an explosion in contract volume. Initially, their process involved manually reading and retyping contract details into spreadsheets, according to the announcement. However, this approach quickly became unsustainable. The team went from reviewing hundreds of contracts monthly to over a thousand in less than six months. This happened without a significant increase in staff, as detailed in the blog post. To solve this, their finance and engineering teams collaborated. They developed a specialized contract data agent. This agent was designed to eliminate repetitive tasks while keeping human experts in control. The company reports that this system processes various document types, including PDFs and even phone photos with handwritten notes.

The Agent’s Three-Step Workflow:

  1. Ingest data: The system takes in diverse contract formats. This includes PDFs, scanned copies, and even marked-up photos. What were once inconsistent files now feed into one pipeline, the company reports.
  2. Inference with prompting: Using retrieval-augmented prompting, the AI parses contracts. It converts them into structured data. The technical report explains that it pulls only relevant information, reasons against it, and displays its work.
  3. Review: Finance experts then review the structured output. The agent highlights non-standard terms. Humans are brought in to review these specific flagged items.

Why This Matters to You

Imagine your business growing rapidly, but your administrative tasks aren’t slowing you down. This internal OpenAI approach directly addresses such scalability issues. It transforms what was once a time-consuming, manual process into an efficient, data-driven workflow. This shift allows your team to focus on higher-value activities. The company reports that the output is a dataset immediately useful across finance workflows. What used to take hours now arrives overnight, annotated and ready for validation.

For example, think of a legal department. Instead of paralegals spending hours sifting through clauses, an AI agent could pre-process documents. This would flag essential dates or unusual terms. This frees up legal professionals for strategic counsel. “The thing is that the heavy lifting happens with AI—and then our teams wake up in the morning to data that’s ready for them to review,” says Wei An Lee, AI Engineer, as mentioned in the release. This means your experts can apply their judgment where it truly counts. How much more strategic could your team be if routine data extraction was automated?

This design ensures confidence in the results. Professionals receive structured, reasoned data at scale. Their expertise then drives the final outcome, according to the company.

The Surprising Finding

Here’s an interesting twist: the AI agent isn’t just extracting data; it’s reasoning and explaining its findings. “We’re not just parsing, we’re reasoning—showing why a term is considered non-standard, citing the reference material, and letting the reviewer confirm the ASC 606 classification,” states Siddharth Jain, AI Engineer. This goes beyond simple automation. It challenges the common assumption that AI can only perform rote tasks. Instead, it acts as a highly intelligent assistant. It provides context and justification for its flags. This allows human experts to make informed decisions quickly. It’s a significant step beyond basic data entry automation, offering a deeper level of insight.

What Happens Next

This contract data agent, initially a approach for contracts, has expanded its reach. The company reports that this architecture now supports procurement, compliance, and even month-end close processes. The underlying principle remains consistent: automate the repetitive work. Keep humans in charge of essential judgment. Engineers describe this as “manual work already done,” not decisions replaced, as detailed in the blog post. This implies a future where finance teams focus on analysis. They will craft the narrative of the numbers, rather than spending their days on painstaking data entry.

For instance, imagine your quarterly financial reporting. Instead of delays due to manual data aggregation, an AI agent could prepare much of the raw data overnight. This allows your team to begin analysis immediately. This enables leaders to scale confidently with growth. They won’t need to grow their teams linearly with increasing workload. “The only way we can scale as OpenAI scales is through this,” Wei An Lee added. “Without it, you’d have to grow your team linearly in lockstep with contract volume. This lets us keep the team lean while handling hypergrowth.” Expect to see more companies adopt similar AI agent strategies in the next 12-24 months. They will seek to streamline their internal operations and achieve hypergrowth without proportional headcount increases.
