This guide introduces the available models and compares their performance. + +--- + +## 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). + +### Latest models comparison + +| Feature | Claude Opus 4.7 | Claude Sonnet 4.6 | Claude Haiku 4.5 | +|:--------|:--------------|:------------------|:-----------------| +| **Description** | Our most capable generally available model for complex reasoning and agentic coding | The best combination of speed and intelligence | The fastest model with near-frontier intelligence | +| **Claude API ID** | claude-opus-4-7 | claude-sonnet-4-6 | claude-haiku-4-5-20251001 | +| **Claude API alias** | claude-opus-4-7 | claude-sonnet-4-6 | claude-haiku-4-5 | +| **AWS Bedrock ID** | anthropic.claude-opus-4-73 | anthropic.claude-sonnet-4-6 | anthropic.claude-haiku-4-5-20251001-v1:0 | +| **Vertex AI ID** | claude-opus-4-7 | claude-sonnet-4-6 | claude-haiku-4-5@20251001 | +| **Pricing**1 | \$5 / input MTok

Access is invitation-only and there is no self-serve sign-up. + + +Every Claude model ID is a pinned snapshot. Models with a date in the ID (for example, `20250929`) are fixed to that specific release. Starting with the Claude 4.6 generation, model IDs use a dateless format that is also a pinned snapshot, not an evergreen pointer. For models before the 4.6 generation, entries in the Claude API alias column are convenience pointers that resolve to a dated model ID. For details on the naming convention and how versioning works, see [Model IDs and versioning](/docs/en/about-claude/models/model-ids-and-versions). + +Starting with **Claude Sonnet 4.5 and all subsequent models** (including Claude Sonnet 4.6), Bedrock offers two endpoint types: **global endpoints** (dynamic routing for maximum availability) and **regional endpoints** (guaranteed data routing through specific geographic regions). Vertex AI offers three endpoint types: global endpoints, **multi-region endpoints** (dynamic routing within a geographic area), and regional endpoints. For more information, see [Cloud platform pricing](/docs/en/about-claude/pricing#cloud-platform-pricing). + +**Claude Platform on AWS** uses the same model IDs as the Claude API (for example, `claude-opus-4-6`), not Bedrock-style IDs. Model lifecycle on Claude Platform on AWS follows Anthropic's first-party [Model deprecations](/docs/en/about-claude/model-deprecations), not Bedrock's. See [Available models](/docs/en/build-with-claude/claude-platform-on-aws#available-models) for the model list. + + +You can query model capabilities and token limits programmatically with the [Models API](/docs/en/api/models/list). The response includes `max_input_tokens`, `max_tokens`, and a `capabilities` object for every available model. + + + +The Max output values above apply to the synchronous Messages API. On the [Message Batches API](/docs/en/build-with-claude/batch-processing#extended-output-beta), Opus 4.7, Opus 4.6, and Sonnet 4.6 support up to 300k output tokens by using the `output-300k-2026-03-24` beta header. + + +

+ +## Prompt and output performance + +Claude 4 models excel in: +- **Performance**: Top-tier results in reasoning, coding, multilingual tasks, long-context handling, honesty, and image processing. See the [Claude 4 blog post](http://www.anthropic.com/news/claude-4) for more information. +- **Engaging responses**: Claude models are ideal for applications that require rich, human-like interactions. + + - If you prefer more concise responses, you can adjust your prompts to guide the model toward the desired output length. Refer to the [prompt engineering guides](/docs/en/build-with-claude/prompt-engineering) for details. + - For prompting best practices, see [Prompting best practices](/docs/en/build-with-claude/prompt-engineering/claude-prompting-best-practices). +- **Output quality**: When migrating from previous model generations to Claude 4, you may notice larger improvements in overall performance. + +## Migrating to Claude Opus 4.7 + +If you're currently using Claude Opus 4.6 or older Claude models, consider migrating to Claude Opus 4.7 to take advantage of improved intelligence and a step-change jump in agentic coding.
