FAQPage Schema
How do I update Claude Code environment variables when Anthropic releases new models?▼

Updating Claude Code environment variables involves fetching the latest model names from Anthropic's official documentation and applying them to your `env.sh` file. This synchronizes configurations like `ANTHROPIC_MODEL` and subagent settings automatically.

What environment variables need to be changed to use a new Claude model version?▼

Key environment variables include `ANTHROPIC_MODEL`, `ANTHROPIC_DEFAULT_HAIKU_MODEL`, `ANTHROPIC_DEFAULT_OPUS_MODEL`, `ANTHROPIC_DEFAULT_SONNET_MODEL`, and `CLAUDE_CODE_SUBAGENT_MODEL`. These control default model selection and subagent behavior.

Can I automate fetching the latest Claude model names for my configuration?▼

Yes, you can automate fetching the latest Claude model names by retrieving data from Anthropic's official documentation. This process updates the `env.sh` and `env.sh.example` files with the newest model identifiers.

Does this environment variable update process support Vertex AI configurations?▼

The environment variable update process targets standard Claude Code configurations including Vertex AI environments. It ensures the `env.sh` file aligns with current model offerings for seamless integration across supported platforms.

What is the best way to synchronize `env.sh` with the latest Anthropic model offerings?▼

The best way to synchronize `env.sh` is to fetch the current model identifiers directly from official Anthropic documentation. This ensures your environment configuration aligns with the most recent AI capabilities without manual searching.

Why does my Claude Code subagent configuration not match the latest model release?▼

Your `CLAUDE_CODE_SUBAGENT_MODEL` variable may be outdated if it was not updated when new models were released. Synchronizing your `env.sh` file with the latest Anthropic documentation resolves this mismatch.
