Expose Codex standalone web search for OpenAI Responses Lite models by Copilot · Pull Request #67246 · github/gh-aw

Copilot · 2026-10-09T17:15:51Z

Codex gives Responses Lite models a standalone web.run tool rather than hosted web_search, but the generated openai-proxy provider did not advertise support for it. As a result, models such as gpt-5.6-terra had no search tool even with hosted web enabled.

Provider configuration: Set supports_standalone_web_search = true for Codex’s OpenAI proxy only when network.hosted-web is enabled. Leave the flag absent otherwise.
Policy validation: Reject network.hosted-web.max-uses for Codex with OpenAI inference because standalone search does not support that limit.
Coverage and docs: Add config and validation tests, document the behavior, and regenerate the two affected workflow lock files.

The separate AWF api-proxy rejection of standalone search calls remains outside this change.

Fixes Codex: no web search tool for Responses Lite models (openai-proxy provider lacks supports_standalone_web_search) #67148

Merged the latest main and fixed the reported build/test and linter failures in commit f553cea. The CI checks still need a human-triggered rerun; this is a top-level PR comment, not a resolvable review thread.
