# Models available on BetterToken: updates and Model IDs

> Browse BetterToken model updates by family, find exact Model IDs, and follow setup guides for Claude Code, Codex CLI, image APIs, and external tools.

Check the [model plaza](https://bettertoken.ai/pricing) for currently available models, their exact Model IDs, and current prices. Use the announcements below to compare suitable tasks and find setup guidance; confirm availability in the model plaza before configuring your tool.

## How to switch models in your tool

Use your BetterToken API Key and copy the exact Model ID from the model plaza into your client's model setting. Choose the Base URL for your protocol: `https://bettertoken.ai` for Claude Code or Anthropic Messages, and `https://bettertoken.ai/v1` for Codex CLI or OpenAI-compatible clients.

* [Model selection guide](/en/faq/model-calling/model-selection-guide.md): compare models by task, quality, speed, and context length.
* [Verify model identity](/en/faq/model-calling/model-version-identity.md): check which model was used through request records and response fields.
* [Switch models in Claude Code](/en/ai-tools/claude-code.md#switch-models): update your configuration and restart, or use `/model YOUR_MODEL_ID` during a session.
* [Supported tools and setup guides](/en/ai-tools/overview.md): find your tool's authentication, Base URL, and model configuration steps.

## Common questions

### When can I use a new model in my tool?

Confirm that the model is available in the model plaza, then configure its Model ID using your tool's setup guide. If your client does not refresh its model list automatically, restart it and send a short test request. Check the matching request in the **Dashboard**.

### Does Model ID capitalization matter?

Copy the Model ID exactly, preserving capitalization and punctuation. For example, use `MiniMax-M3.1-Flash` for MiniMax M3.1 Flash. A display name or an ID from another platform may differ from the BetterToken Model ID.

### Can Claude Desktop use every model listed here?

Claude Desktop supports only Claude models because of a client limitation. One BetterToken API Key works with all available models; Claude Code can call GPT and other available models through Anthropic Messages. See the [Claude Desktop setup guide](/en/faq/claude-desktop-bettertoken-api.md).
