Claude Opus 4.7

Claude Opus 4.7 is the top tier of Anthropic's Claude 4 family, positioned for the hardest reasoning, research, and long-horizon agent tasks. Opus models are tuned for deep multi-step thinking, sustained tool-use loops, and complex codebase work where quality matters more than throughput. Reach for it when smaller Claude tiers plateau on reasoning depth, refactor-scale coding, or extended autonomous agent runs.
