Claude Opus 4.8 (batch)

Anthropic · Multimodal · Released May 2026

Claude Opus 4.8 is Anthropic's previous-generation flagship model, supporting text, image, and file inputs with a 1M-token context window and extended reasoning capabilities.

Strengths: Delivers strong performance on long-horizon agentic work, autonomous reasoning, and knowledge-intensive tasks across multiple modalities.
Best for: Complex multi-turn workflows, reasoning-heavy applications, and tasks requiring sustained context and autonomous problem-solving; now superseded by Claude Opus 5 for cutting-edge reasoning work.
Limitations: Has been superseded by Claude Opus 5 (released mid-2026) for advanced reasoning tasks, and by Claude Fable 5 for the most demanding agentic and coding work.
