OpenClaw version

Model

openai/gpt-5.5

Provider / routing chain

TUI session model: openai/gpt-5.5 ↓ OpenClaw agent defaults agents.defaults.model = openai/gpt-5.5 ↓ provider/model parse provider = openai modelId = gpt-5.5 ↓ OpenClaw policy OpenAI provider uses Codex runtime by default ↓ runtime selected Runtime: OpenAI Codex runtime id = codex ↓ runtime provider rewrite provider openai → openai-codex ↓ execution target becomes openai-codex/gpt-5.5 ↓ failure Unknown model: openai-codex/gpt-5.5

Additional provider/model setup details

Evidence:

  • openclaw models list –provider openai shows:
    • openai/gpt-5.4
    • openai/gpt-5.5
  • openclaw models list –provider openai-codex shows no models.
  • Standalone Codex CLI works correctly:
    • OpenAI Codex v0.133.0
    • GPT-5.5 executes successfully
    • Tool use functions normally

Diagnostics:

Additional Investigation:

  • openclaw.json validated successfully.
  • No remaining agentRuntime overrides.
  • Session cleanup completed successfully.
  • Gateway healthy.
  • OAuth healthy.
  • Codex plugin version matches OpenClaw version.
  • Issue appears to occur during OpenAI → Codex runtime/provider translation.
