Released: April 16, 2026
Context Window: Up to 1 Million tokens (200K standard, 1M in beta/extended)
Key Improvements: Major gains in agentic coding, visual reasoning, tool use, and long-horizon reliability over Opus 4.6
Variants: Opus 4.7 (standard), with effort control (Low → Max, including new “xHigh” tier)
Access: claude.ai, Anthropic API, Claude Code, AWS Bedrock, Vertex AI, etc.This manual focuses on Opus 4.7 — Anthropic’s powerful production model optimized for complex, reliable, and agentic work.

Getting Started

• Platforms: claude.ai (Pro/Max plans), Anthropic API, Claude Code IDE integration.
• Effort Levels (critical for Opus 4.7):
  • High / xHigh — Recommended default for coding & agentic tasks.
  • Max — For the hardest problems (higher latency).
  • Use effort parameter in API or toggle in interface.
• Recommended Settings:
  • Temperature: 0.0–0.5 for precise work, 0.7+ for creative.
  • Use XML tags for structured output.
  • Enable extended thinking / artifacts where available.
  • For best results: Be literal, explicit, and provide clear constraints.
