Models overview
Claude is a family of state-of-the-art large language models developed by Anthropic. Compare the current lineup, find the model ID for every platform, and open each model's page for its full specs and resources.
Compare models
If you're unsure which model to use, start with Claude Opus 5 for complex agentic coding and enterprise work; for the highest available capability, use Claude Fable 5. All current models support text and image input, text output, multilingual capabilities, vision, and tool use; each model’s page lists the platforms it is available on.

Using the Models API
You can query model capabilities and token limits programmatically with the Models API. The response includes max_input_tokens, max_tokens, and a capabilities object for every available model.
Prompt and output performance
Current Claude models excel in:
- Performance: Top-tier results in reasoning, coding, multilingual tasks, long-context handling, honesty, and image processing. See Prompting best practices for general and model-specific prompting guidance.
- Engaging responses: Claude models are ideal for applications that require rich, human-like interactions. If you prefer more concise responses, adjust your prompts to guide the model toward the desired output length. Refer to the prompt engineering guides for details.
- Output quality: When migrating from a previous model generation, you may notice larger improvements in overall performance. If you're on Claude Opus 4.8 or earlier, see Migrating to Claude Opus 5.
