Legora Uses GPT-6 Astra to Review 41 Financial Documents in Minutes

European startup Legora has demonstrated the transformative potential of OpenAI’s newly launched GPT-6 Astra by reviewing 41 financial documents in mere minutes. The task, known as financial-statement tie-out, typically takes legal teams hours or even days to complete manually. This breakthrough not only accelerated workflows but also improved accuracy, with Astra identifying all four deliberately planted errors during the test.

Legora specializes in building agentic systems for legal and professional workflows, serving more than 100,000 professionals across 1,800 organizations globally. The company’s use of GPT-6 Astra marks a significant leap in leveraging artificial intelligence for heavy-duty document processing. “The ability to ingest and process such a large volume of complex financial data is a game-changer,” said Percevale Perks, Legal Engineer at Legora.

40% Workflow Improvement with Astra

In the trial, Legora reported a nearly 40% improvement in workflow performance compared to its prior benchmarks. Astra’s capabilities enabled the system to check every figure in draft accounts against supporting schedules, surfacing discrepancies like a £500,000 revenue note gap. The AI even preserved correct results from earlier models while completing 50 additional checks previously overlooked.

The enhanced speed and accuracy provide legal professionals with a more complete first pass, while leaving final judgment in human hands—a critical safeguard in complex legal and financial contexts. This hybrid approach aligns with OpenAI’s focus on keeping a human in the loop, especially for ethical and professional decision-making.

GPT-6 Astra: A New Era for AI Reasoning

Released on September 3, 2026, GPT-6 Astra is OpenAI’s flagship reasoning model, boasting significant advancements in complex problem-solving, coding, and multi-step workflows. OpenAI describes Astra as a generational leap, with applications ranging from cybersecurity to health diagnostics. In legal and compliance use cases like Legora’s, Astra excels by combining high processing power with robust safeguards, ensuring reliability and alignment.

According to OpenAI, Astra is priced at $10 per 1 million input tokens and $50 per 1 million output tokens, making it accessible for enterprise-scale operations while retaining high-end capabilities. Early adopters like Legora and Playco have highlighted its ability to cut manual effort dramatically across diverse tasks.

Scaling Across Legal and Professional Fields

Legora’s success with GPT-6 Astra underscores a broader trend of AI integration into traditionally human-dominant fields. By automating tedious processes like financial tie-outs, companies can reallocate resources to higher-value tasks. Legora plans to expand its use of Astra into other domains such as audit, tax, and compliance, positioning AI as an enabler rather than a replacement for expert judgment.

For OpenAI, Astra’s launch represents a major milestone, with controlled rollouts ensuring safe deployment of its most powerful capabilities. As the model becomes more widely available, its impact on industries like legal tech, finance, and beyond could be profound.

With a 40% performance boost and real-world cases showcasing its capabilities, Astra is already proving its worth in reshaping professional workflows. Companies like Legora are leading the charge, demonstrating how AI can enhance both speed and reliability without compromising on human oversight.
