Summary

Adds the GPT-5.6 model family (released 2026-07-09) to the Codex adapter so users can select the new tiers, and makes gpt-5.6-terra the default (5.5-class quality at ~2x lower cost).

Changes

  • lib/yoke/adapters/codex.js
    • Add gpt-5.6-terra, gpt-5.6-sol, gpt-5.6-luna to CODEX_MODELS (older ids kept as selectable options)
    • Flip the default model fallbacks (3 sites) and defaultModel from gpt-5.5 to gpt-5.6-terra
  • lib/public/modules/app-panels.js
    • Register gpt-5.6 context window (272000) in KNOWN_CONTEXT_WINDOWS so the context panel reports usage correctly instead of the 200000 fallback

Model tiers

Tier id Notes
Sol gpt-5.6-sol Flagship, deepest reasoning
Terra gpt-5.6-terra Balanced, ~5.5 quality at 2x lower cost (new default)
Luna gpt-5.6-luna Fast/cheap, high-volume

Verification

  • The bundled @openai/codex 0.144.4 native binary contains all three gpt-5.6-* model id strings, confirming the CLI recognizes them (support landed in codex 0.143.0).
  • Syntax check passes on both files.

Notes

  • codex.js internal subagent still uses gpt-5.4-mini (valid, unchanged; could move to gpt-5.6-luna later).
  • A full end-to-end run against an authenticated Codex session was not performed here (no auth in this environment); binary-level id verification stands in for it.

Add the GPT-5.6 model family (gpt-5.6-sol, gpt-5.6-terra,
gpt-5.6-luna) to the Codex adapter's model list and make
gpt-5.6-terra the default (5.5-class quality at lower cost).

Register the 5.6 context window (272000) so the context panel
reports usage correctly instead of falling back to 200000.

Verified the bundled @openai/codex 0.144.4 binary already
recognizes all three model ids.
