Source Summary

OpenAI introduced **GPT-5.6**, claiming better **token efficiency, cost-performance, and capacity for difficult work**. The supplied material contains no supporting measurements.

Practical Implication

Builders should keep existing model-selection tests and cost traces in place rather than changing agent defaults from the claims alone.

Agent-Ready Context
