## Why Included

OpenAI introduced GPT-5.6 with claims of improved token efficiency and cost-performance, but supplied no measurements or access details for model selection.

## 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

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

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

**Access details are not included**, and the lack of benchmarks prevents comparison with earlier models or competing options.

## Context Map

- Layer: model
- Domains: None
- Topics: model-selection, reasoning

## Uncertainty

- **Access details are not included**, and the lack of benchmarks prevents comparison with earlier models or competing options.
