258258`bash_20250124` is the current version of the tool, and it requires no beta header. Every model from Claude Sonnet 3.7 ([retired](https://platform.claude.com/docs/en/about-claude/model-deprecations)) onward accepts it, including all current Claude models.

260The original `bash_20241022` version works only with the October 2024 Claude Sonnet 3.5 model ([retired](https://platform.claude.com/docs/en/about-claude/model-deprecations)). Requests that use it need the `anthropic-beta: computer-use-2024-10-22` header, and the SDKs expose it only in their beta namespaces. New integrations should use `bash_20250124`.
