🏢 Official Anthropic Resources

The authoritative source for everything Claude - directly from Anthropic

🧠 Current Models (2026)

• Claude Fable 5 (Jun 9, 2026) - Anthropic's most capable widely released model, for the most demanding reasoning and long-horizon agentic work. State-of-the-art on nearly all tested benchmarks — software engineering, knowledge work, vision, and scientific research — with its lead growing on longer, more complex tasks (highest score on Cognition's FrontierBench, first model past 90% on Anthropic's core long-running analytics benchmark, strongest finance model Anthropic has tested). Thinking is always on; the raw chain of thought is never returned. Safety classifiers route high-risk requests (cybersecurity, bio/chem, model distillation — under 5% of sessions) to Opus 4.8. Requires 30-day data retention (not available under zero data retention). Claude Mythos 5 is the same underlying model with safeguards lifted for authorized users (Project Glasswing). Announcement | Docs | System Card
• Claude Opus 5 (Jul 24, 2026) - The model to start with for complex agentic coding and enterprise work, and a step change over Opus 4.8 on deep reasoning, long-horizon agentic execution, and test-time compute scaling — at half the price of Fable 5. Thinking is now on by default (omit thinking and you get adaptive), the full low→max effort ladder is supported, and the minimum cacheable prompt drops to 512 tokens. Fast mode (speed: "fast") is available on the Claude API only. Announcement | Migration guide | System Card
• Claude Sonnet 5 (Jun 30, 2026) - The best combination of speed and intelligence, reaching what used to be Opus-tier quality on coding and agentic tasks. First Sonnet-tier model with the xhigh effort level and high-resolution vision (2,576px long edge). Uses the newer tokenizer, so the same text produces ~30% more tokens than Sonnet 4.6 — re-baseline your token budgets when you migrate. Announcement | System Card
• Claude Haiku 4.5 (Oct 2025) - Still the fastest model with near-frontier intelligence. Perfect for high-volume, real-time, and sub-agent tasks. Announcement

Key specs (API):

• Fable 5: claude-fable-5 • $10/$50 per MTok • 1M context / 128K max output
• Opus 5: claude-opus-5 • $5/$25 per MTok • 1M context / 128K max output
• Sonnet 5: claude-sonnet-5 • $3/$15 per MTok ($2/$10 introductory through Aug 31, 2026) • 1M context / 128K max output
• Haiku 4.5: claude-haiku-4-5 • $1/$5 per MTok • 200K context / 64K max output

Model IDs from the 4.6 generation onward are dateless but still pinned snapshots, not evergreen pointers — see Model IDs and versioning. Full comparison: Models overview | Pricing

Previous generations (still active)

• Claude Opus 4.8 (May 28, 2026) - Highly autonomous, strong on long-horizon agentic work, knowledge work, and memory, with clearer and warmer writing than 4.7. Introduced Dynamic Workflows in Claude Code (plan work, run hundreds of parallel subagents in one session, verify before returning), effort control on claude.ai, and mid-conversation system messages via the Messages API. Still the recommended fallback for Fable 5 refusals. Announcement | What's new | System Card
• Claude Opus 4.7 (Apr 16, 2026) - Introduced high-resolution vision (images up to ~3.75 MP / 2,576px long edge), the xhigh effort level, and task budgets. Announcement | System Card
• Claude Opus 4.6 (Feb 5, 2026) - Introduced the 1M token context window and adaptive thinking. Announcement | System Card
• Claude Sonnet 4.6 (Feb 17, 2026) - The previous speed/cost balance pick, superseded by Sonnet 5. Announcement

Migrating? Extended thinking with a fixed budget_tokens, the sampling parameters (temperature/top_p/top_k), and last-assistant-turn prefills all return a 400 on the Claude 5 family. Use adaptive thinking plus the effort parameter instead, and structured outputs in place of prefills. Full list: Migration guide.

☁️ Cloud Providers

Official access to Claude models through cloud providers (all carry the Claude 5 family — Fable 5 / Opus 5 / Sonnet 5)

• Amazon Bedrock - Fully managed access to the latest Claude models (Fable 5, Opus 5, Sonnet 5, Haiku 4.5). Claude 5 models are served through the Messages-API Bedrock endpoint and take an anthropic. ID prefix (e.g. anthropic.claude-opus-5). Supports cross-region inference, latency optimizations, fine-tuning, agents, guardrails, and deep AWS integration. (Note: Managed Agents and Anthropic server-side tools are not available on Bedrock — use Claude API + tool use there.)
• Claude Platform on AWS - Anthropic-operated access via AWS infrastructure: SigV4 auth, IAM access control, AWS Marketplace billing, and same-day API parity with the first-party API. Model IDs are the bare first-party strings (no anthropic. prefix) — not the same thing as Bedrock.
• Google Cloud Vertex AI Model Garden - Deploy Claude models with provisioned throughput, prompt caching, batch predictions, grounding, and enterprise compliance (FedRAMP High). Great for building agents with Google Cloud tools.
• Microsoft Azure AI Model Catalog (Anthropic Publisher) - Claude models via the AI Model Catalog. Supports serverless deployment, agent building, tool integration, fine-tuning, and billing through existing Azure agreements.
