Codex 0.153.3: Amazon Bedrock Route Picker Adds GPT-6-Astra Model

Release notes

FEATURE

Amazon Bedrock Route Picker Adds GPT-6-Astra Model

When calling Codex in the Amazon Bedrock cloud environment, you now have a new option when selecting models.

This change covers the Mantle route as well as Runtime's global and US routes. As long as your connection uses these paths, you can directly select the GPT-6-Astra model in the model picker. When routing through Mantle or Runtime global/US, you can directly choose GPT-6-Astra in the model picker.

BUGFIX

Corrected GPT-6-Astra Guidance for Asynchronous Clarifications to Use Supported Tools and Recognize Text-Only Limits

When tasks assigned to GPT-6-Astra have unclear requirements, its process for asking clarifying questions in the background is now more reliable. This change corrects the model's built-in guidance when asking asynchronous clarification questions. It now properly calls officially supported tools instead of misusing incompatible channels. At the same time, it correctly recognizes that the tool accepts only plain text, avoiding errors caused by sending unsupported formats.
