0.1.67-beta1 — Copilot tiers point at models that exist
Pre-release
Copilot's model tiers follow Copilot's actual model list again.
Fast points somewhere that exists; capable stops pointing at all (#332)
A Copilot loop's tier maps to a --model flag, and --model takes explicit versioned ids from a fixed set. Those ids turn over.
- Fast now passes
--model gpt-5.6-luna. - Capable passes no flag at all, and so does standard.
Unpinning capable is the interesting half. It was pinned to claude-opus-4.6, an id that had already gone by Copilot 1.0.84 — so a capable loop was asking for a model that no longer existed. Passing nothing lets Copilot choose, and a loop that starts on a model you did not name is better than one that does not start.
Fast keeps a pin because it has no other way to mean anything: passing nothing is what standard already does.
Worth knowing
The same churn that retired claude-opus-4.6 will eventually retire gpt-5.6-luna, and fast is pinned to it. When a fast Copilot loop stops launching, that pin is the first thing to check.
