Anthropic: Claude Opus 4

Exceptional instruction-following and nuanced judgment on ambiguous tasks

Strong agentic coding with deep multi-file project comprehension across its 200K context

Industry-leading long-form writing quality with coherent voice and structure

Reliable on complex multi-step reasoning chains with fewer hallucinations than many peers

Output cost of $75/1M tokens makes it prohibitively expensive for high-volume or production pipelines

No native image generation capability despite multimodal input support

Slower inference than Claude Sonnet 4 or Haiku 3.5, making real-time applications impractical
