Codex CLI hides GPT-5.6 in /model when modelscache.json is stale
A user reports that the Codex CLI model picker on one Linux machine does not show any GPT-5.6 options, even though the same ChatGPT login exposes them on another laptop.
Evidence
- The installed binary is codex-cli 0.144.4
- /.codex/modelscache.json still says clientversion: "0.142.3"
- The cache contains only five models, including gpt-5.5 and gpt-5.4
- codex debug models --bundled does include GPT-5.6 variants such as gpt-5.6-sol, gpt-5.6-terra, and gpt-5.6-luna
Impact
The interactive /model picker appears to rely on the stale cache, so users cannot select GPT-5.6 from this machine despite it being available in the bundled catalog and on another device.
