Summary

Extends the "ultra""max" reasoning_effort clamp from GPT-5.6-only to all models.

Problem

_reasoning_config_for_model() only clamped "ultra" to "max" for GPT-5.6 models. GLM models (z-ai/glm-5.2) reject "ultra" with HTTP 400:

reasoning.effort: Invalid option: expected one of "max"|"xhigh"|"high"|"medium"|"low"|"minimal"|"none"

This triggered silent fallback to the configured fallback provider without surfacing the root cause.

Fix

  • agent/transports/chat_completions.py: Remove the model-specific gpt-5.6 guard — clamp "ultra" to "max" for all models since no upstream provider accepts "ultra" as a valid effort value.
  • tests/agent/transports/test_chat_completions.py: Add 3 tests:
    • GLM model gets clamped
    • Arbitrary models get clamped
    • Non-ultra effort values pass through unchanged

Fixes #70058

…ousResearch#70058)

The 'ultra' effort label is an internal convenience used by the desktop
model picker and /reasoning ultra, but no upstream provider API accepts
it verbatim.  Previously only GPT-5.6 models were clamped; GLM models
(z-ai/glm-5.2) return HTTP 400 and trigger silent fallback to the
configured fallback provider.

Extend the clamp to fire for every model, preventing the 400 loop and
the silent fallback activation that confused users.

Related to #69917 and #70058. #69917 maps ultra only for documented GLM aliases; this PR changes the policy for every Chat Completions model and also bundles unrelated Desktop/audit files. The universal mapping needs a maintainer decision rather than a duplicate closure.

Thanks for isolating a real GLM/Nous Chat Completions failure. Current main still limits the normalizer to GPT-5.6 at agent/transports/chat_completions.py:25-32, while the Nous profile forwards enabled reasoning configurations at plugins/model-providers/nous/__init__.py:58-68.

Problems

  • The fix does not cover iteration-limit summaries. agent/chat_completion_helpers.py:2199-2207 writes agent.reasoning_config directly to summary_extra_body["reasoning"], then sends it directly via chat.completions.create() at agent/chat_completion_helpers.py:2302-2308; this bypasses the changed transport helper.
  • The unrelated Desktop diff is syntactically invalid: checking the exact PR revision of apps/desktop/scripts/stage-native-deps.mjs as an ES module fails at proposed line 198 on the literal \`` token. The added audit_and_fix.tsis also an unrelated placeholder containing literal\n` bytes.

Suggested changes

  • Keep this PR focused: remove the Desktop and audit artifacts.
  • Apply the same normalization to the direct summary request path and cover that payload in a regression test.
  • The existing maintainer discussion correctly notes that universal mapping needs a decision; the current tests only exercise the helper, not provider contracts.

This inserts a literal backslash before the template literal. The exact PR file fails node --input-type=module --check here with SyntaxError: Invalid or unexpected token; please remove this unrelated Desktop change.

Please remove this unrelated placeholder. Its literal \n bytes leave the intended export inside the opening line comment, so it does not define executable automation.

Thanks for this — you were the earliest general fix for the ultra leak (26 days ahead), and the chat_completions change here was exactly right. Unfortunately the branch also carried unrelated corruption in apps/desktop/scripts/stage-native-deps.mjs (escaped-backtick mangling) and a stray audit_and_fix.ts, so it couldn't be taken as-is. The substantive fix landed via PR #90330 (which generalizes ultra → max for every model on the transport plus the sibling sites). Closing — credit noted in the PR body.
