OpenAI shared a case study showing GPT-6 Astra processing a complex 50-tab tax workbook at double the speed of its predecessor, GPT-5.6 Sol. The workload was handled by Basis, a firm exploring LLM-driven tax and accounting automation.

The performance gain is attributed not only to raw speed but also to Astra's stronger grasp of user intent. Basis indicated this improved comprehension gives the team greater confidence in deploying the model for real-world tax tasks, where precision and contextual understanding are critical.

Tax workbooks with dozens of interconnected tabs represent a demanding benchmark for LLMs, requiring sustained reasoning across structured data, cross-references, and domain-specific rules. A twofold speed improvement on such a workload suggests meaningful progress in handling multi-step analytical tasks.

For professional services firms, faster and more reliable LLM processing of complex financial documents could significantly reduce manual review overhead. However, real-world adoption will still depend on accuracy, auditability, and regulatory compliance rather than speed alone.
