## Choosing a model
If you're unsure which model to use, consider starting with **Claude Opus 4.7** for the most complex tasks. It is our most capable generally available model, with a step-change improvement in agentic coding over Claude Opus 4.6.
All current Claude models support text and image input, text output, multilingual capabilities, and vision. Models are available through the Claude API, [Claude Platform on AWS](/docs/en/build-with-claude/claude-platform-on-aws), [Amazon Bedrock](/docs/en/build-with-claude/claude-in-amazon-bedrock), [Vertex AI](/docs/en/build-with-claude/claude-on-vertex-ai), and [Microsoft Foundry](/docs/en/build-with-claude/claude-in-microsoft-foundry).
Once you've picked a model, [learn how to make your first API call](/docs/en/get-started).
