- 1M-token context: works across large codebases, extensive documents, and long-running project histories
- Advanced coding: plans carefully, operates across larger codebases, catches mistakes, and produces production-ready implementations with less oversight
- Reliable agents: orchestrates multi-tool workflows, sustains long-running tasks, and verifies results before reporting completion
- Multimodal knowledge work: reasons over PDFs, diagrams, and other unstructured content for research and enterprise workflows
- Adaptive thinking: adjusts reasoning effort to task complexity, spending more time on harder problems and responding faster to simpler ones
Anthropic lists Claude Opus 4.8 API pricing starting at $5 per million input tokens and $25 per million output tokens, with separate savings available through prompt caching and batch processing. US-only inference is offered at 1.1× standard input and output pricing.
