## Summary

Microsoft will roll out Advanced NL2SQL, advanced DAX generation, and the GPT-5.6 Terra model to the standard runtime of Fabric data agents between November 2 and November 10, 2026. The changes are automatic; users cannot enable them manually. Microsoft says internal tests show NL2SQL accuracy rising from 78.8% to 90.9% and P95 processing time dropping from 46.8 seconds to 32.9 seconds, though it cautions that results may differ on individual schemas and instructions.

Organizations are advised to save baseline responses, then re‑test 10 to 20 daily questions during the rollout, checking generated SQL or DAX, clarification prompts, and latency. The guidance stresses comparing query structure and referenced tables, not just answer text, especially for metrics like sales or inventory. Teams, Microsoft 365 Copilot, or Copilot Studio users should run real‑world expressions and note any discrepancies before expanding automation.

The update aims to improve accuracy but does not guarantee compatibility with existing settings, and Microsoft’s internal figures do not assure the same outcomes for every customer. Companies should record their own accuracy, processing time, and human verification effort before deciding to adopt the new runtime fully.

## Key points

- Microsoft deploys Advanced NL2SQL, advanced DAX generation, and GPT-5.6 Terra to Fabric data agents from November 2 to November 10, 2026
- Internal tests show NL2SQL accuracy rising from 78.8% to 90.9% and P95 latency dropping from 46.8 seconds to 32.9 seconds
- Users should baseline and re‑test 10 to 20 daily questions, checking queries, clarification prompts, and processing times

## Why it matters

The automatic update could change query results and response times for businesses relying on Fabric data agents, so verifying impact is essential to avoid incorrect decisions.
