Gone from the catalogue: openai/gpt-5.1-chat

[Yesol-Pilot]

openai/gpt-5.1-chat is gone from the catalog.

No end-of-life date was ever published for it. It left the catalogue we watch - confirm with your provider before you migrate.

Nearest openai model still listed with at least as much context: openai/gpt-5.1 at $10.00 per million output tokens, against the $10.00 it cost.
