Anthropic outlines Claude model lineup and access options

Anthropic’s Claude family now spans several large language models available through the Claude API, Claude Platform on AWS, Amazon Bedrock, Vertex AI, and Microsoft Foundry. Claude Opus 4.8 is positioned for complex reasoning, long-horizon agentic coding, and high-autonomy work, while Claude Sonnet 4.6 is described as the best combination of speed and intelligence. Claude Haiku 4.5 is the fastest option with near-frontier intelligence.

Claude Fable 5 is Anthropic’s most capable widely released model and is generally available beginning June 9, 2026. Claude Mythos 5 is available in limited availability through Project Glasswing for approved customers. Both models support adaptive thinking, a context window of 1M tokens, max output of 128k tokens, and pricing of $10 / $50 per MTok (input / output).

Current Claude models support text and image input, text output, multilingual capabilities, and vision. Model IDs are pinned snapshots, with dateless IDs from the Claude 4.6 generation onward also fixed to a release rather than acting as evergreen pointers. Developers can query model capabilities and token limits programmatically through the Models API.
