OpenAI published version 0.167.2 of its Codex client, introducing a change to how tool updates are transmitted on Google Cloud Vertex AI.confirmed According to the release notes for rust-v0.167.2, the system now sends tool updates incrementally by default in this environment.reportedThe 0.167.2 release alters the default tool update transmission protocol for Vertex AI deployments to an incremental model. This shift affects the baseline operation for users deploying Codex on Vertex AI, altering the previous default state for tool update delivery.
The figures
- Version number: 0.167.2 (OpenAI Codex releases)reported
- Previous version: 0.167.1 (OpenAI Codex releases)reported
- Issue references: #60617 and #60848 (OpenAI Codex releases)reported
Behind the figures
The source material lists version numbers and associated issue identifiers but does not describe a methodology for measuring performance, latency, or accuracy. The numbers #60617 and #60848 are cited in the release notes without further explanation of their origin or resolution status. No independent benchmarks or third-party measurements are provided in the advisory.
What it means for your stack
To maintain the previous behavior, engineers must explicitly opt out by adding `incremental_tools_legacy_gcp = false` under the `[features]` section in their `config.toml` file. This configuration change is required to revert to the legacy update mechanism.
Building on this
Inference engineers can rely on the documented interface for opting out of incremental updates if their existing workflows depend on the legacy behavior. The capability to toggle this feature via `config.toml` allows for controlled testing of the new incremental transmission model. Developers should verify their deployment configurations to ensure they align with the new default, especially if automatic tool updates are critical to their pipeline stability.
Why it matters
- The default change on Vertex AI may require configuration updates for existing deployments relying on the previous behavior.
- The explicit opt-out mechanism provides a clear path for users who need to maintain legacy tool update patterns.
- Reference to issues #60617 and #60848 suggests specific development work underpins this change, though details are not provided.
- The release notes specify that the incremental update default applies to Google Cloud Vertex AI.
