Legora, an agentic operating system for legal and professional work, is used by over 100,000 professionals across more than 1,800 in-house legal departments and law firms in over 50 markets. Its legal engineers adapt the platform to customer workflows, including financial-statement tie-out, which can take hours or days.

Using GPT-6 Astra, Legora’s Agent completed the tie-out across 41 documents in a single run, within minutes. It checked every balance against supporting schedules, surfaced breaks, and recorded each check, providing a granular record for review.

Legora evaluated GPT-6 Astra with its Benchmark for Agentic Reasoning (BAR). GPT-6 Astra improved performance by nearly 40% over the previous model on the financial-statement workflow, with an average improvement of about 3% across all tasks. It found all four planted errors, including a £500,000 gap, and completed around 50 more checks.

The Agent handles exhaustive comparison while the expert retains judgment, keeping a human in the loop as Legora expands into audit, tax, compliance, and risk.
