Published by Alex Sorokoletov
Part of the Codex CLI Version Tracker series. | Codex on GitHub | Official Changelog
Codex CLI v0.167.1 is a small patch over v0.167.0. It adds opt-in incremental tools on the regular OpenAI Responses path (#59832), and restricts the existing legacy incremental tools to Amazon Bedrock providers (#60040).[1]
What shipped#
Both changes in this release touch incremental tools, each along a different provider path.
| Change | What it does |
|---|---|
| OpenAI Responses | Adds opt-in incremental tools on the regular OpenAI Responses path (#59832).[1] |
| Amazon Bedrock | Restricts legacy incremental tools to Amazon Bedrock providers (#60040).[1] |
No environment variables, model identifiers, or command names changed between v0.167.0 and v0.167.1.
Incremental tools, split by provider path#
Each change names a different backend. One opens the regular OpenAI Responses path to opt-in incremental tools; the other keeps the legacy incremental tools scoped to Amazon Bedrock providers. The two provider paths move separately in the same release. The OpenAI Responses change is opt-in, so on that path it applies where it is turned on rather than by default.
That split is the point release's shape. Incremental tools are not handled the same way across every backend Codex talks to; this release advances the OpenAI Responses path and narrows the Bedrock one, so a session's handling tracks the provider under it rather than a single shared path. Nothing else in the surface moved, which marks v0.167.1 as a provider-scoped follow-on to v0.167.0 rather than a feature release.
