🏢 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 4.8 (May 28, 2026) - Anthropic's current flagship Opus — highly autonomous, state-of-the-art on long-horizon agentic work, knowledge work, and memory, with clearer and warmer writing. Gains across coding, agentic reasoning, and analysis over Opus 4.7; early testers found it ~4x less likely to leave flaws in its own code unremarked. New: Dynamic Workflows in Claude Code (research preview — plan work, run hundreds of parallel subagents in one session, verify before returning, enabling codebase-scale migrations), effort control on claude.ai, and mid-conversation system messages via the Messages API. Same price as Opus 4.7. Announcement | What's new | System Card
• Claude Opus 4.7 (Apr 16, 2026) - Previous-generation Opus. Highly autonomous, with strong long-horizon agentic work, knowledge work, vision (images up to ~3.75 MP / 2,576px long edge), and file-system memory across sessions. Introduced the xhigh effort level and task budgets (beta). Announcement | System Card
• Claude Sonnet 4.6 (Feb 17, 2026) - Best balance of intelligence, speed, and cost. Near-Opus performance on coding, computer use (multi-tab forms, spreadsheets), and professional tasks. Default model for many plans.

Key specs (API):

• Fable 5: claude-fable-5 • $10/$50 per MTok • 1M context / 128K max output
