Auto-generated by model-addition-agent for aws-bedrock-mantle/openai.gpt-5.6-terra.


Note

Low Risk
Purely additive model configuration with no runtime or application logic changes; incorrect pricing or limits would only affect cost/routing metadata.

Overview
Adds a new aws-bedrock-mantle catalog file for openai.gpt-5.6-terra, marking it active with chat mode and serverless provisioning.

The entry defines regional token pricing (including cache read/create and cumulative tiered input/output above 272k tokens) for us-west-2, us-east-2, and us-east-1, plus 1.05M context, 128k max output, text/image input, and capabilities such as tools, structured/JSON output, prompt caching, and thinking.

Missing long-context cache tiers

Medium Severity

Each cost entry sets tiered_pricing with cumulative input and output tiers from 272000 tokens, but omits cache_read and cache_write tiers present on the matching providers/openai/gpt-5.6-terra.yaml pricing. Long-context requests can be costed with base cache rates instead of the higher tier rates.

Incorrect cache_control feature flag

Medium Severity

The model lists cache_control among its features, but OpenAI GPT-5.6 Terra entries in this repo only declare prompt_caching, and no other OpenAI provider YAML uses cache_control. That flag describes Anthropic-style cache breakpoints, not this model’s caching API.
