Remap the picker's built-in tier rows to gateway model ids - #10
Merged
Conversation
Selecting 'Opus 4.8' (or Sonnet/Haiku) in /model silently broke the session:
those rows point at Anthropic's dated first-party ids, which the proxy does
not serve. ANTHROPIC_DEFAULT_{OPUS,SONNET,HAIKU}_MODEL remaps them to the
gateway's ids, labeled '(qBraid)' so the provenance is visible.
Live report that motivated it: /model -> 'Opus 4.8' -> next reply claims to
be gpt-5.6-luna. The switch never took effect on the wire; the self-report
echoes whatever id Claude Code puts in the system prompt.

Live dogfood finding: selecting the built-in Opus 4.8 / Sonnet / Haiku rows in
/modelsilently no-ops — they carry Anthropic's dated first-party ids (claude-opus-4-8-20250805-style), which the proxy doesn't serve. The session keeps its old model while the UI claims the switch happened; the model's own self-report then adds to the confusion (it echoes whatever Claude Code's system prompt says, not the wire).Fix:
ANTHROPIC_DEFAULT_{OPUS,SONNET,HAIKU}_MODEL(+_NAME) remap those rows toclaude-opus-5/claude-sonnet-4-6/claude-haiku-4-5, labeled (qBraid) so provenance is visible in the picker. Documented mechanism (seedocs/research/2026-08-20-model-picker.md, mechanism 3).Note: the haiku slot also serves background traffic, so remapping it keeps that on the gateway too — previously background calls to a dated haiku id would also have failed through the proxy.
Verified: launcher deploys, session answers on the remapped default; suites green (routing 6/6, shellcheck, bash 3.2). Windows .cmd updated equivalently.
