Claude Code Suggests the Model You Meant When a Model Name Is Mistyped

Claude CodeView original changelog

Claude Code 2.1.319 fixes a mistyped model name, such as opus-5-5, telling the user to update Claude Code. It now suggests the model the user meant.

Key Takeaways

  • A mistyped name like opus-5-5 no longer tells the user to update Claude Code.
  • Claude Code now suggests the intended model.
  • The old message pointed at a software update rather than the typo.
  • It shipped in 2.1.319.

The fix

Before 2.1.319, a mistyped model name such as opus-5-5 produced a message telling the user to update Claude Code. In 2.1.319 the message suggests the model the user meant instead.

Why it matters

The old message pointed at a software update rather than at the typo. The new one names the model the user meant.
