Unclear It is not clear which models these two entries belong to.
What
Claude Code has a built-in table describing the models it can use. Two entries changed. The findings do not show which model names they belong to.
One entry, the one with hard_limit 190000 and auto_permission_mode "unavailable", now has voice_model: "claude-haiku-5-5".
Another entry now has supports_fast_mode set to true.
That same entry's min_claude_code_version, the oldest Claude Code version that will offer the model, rose from "2.1.251" to "2.1.290".
Why
These values decide which models are offered for voice and for fast mode. They also decide which Claude Code versions show the model at all. Versions older than 2.1.290 will no longer see the second entry.
