Frequently Asked Questions about Claude Opus 4.7

What is Claude Opus 4.7?

Claude Opus 4.7 is the latest flagship AI model from Anthropic, announced on April 16, 2026. It is the successor to Claude Opus 4.6 and represents the most capable model in the Claude family. It excels at coding, complex reasoning, agentic tasks, and multimodal understanding. It is available via the Anthropic API and through claude.ai for Claude Pro subscribers.

How does Claude Opus 4.7 compare to GPT-5?

Both are top-tier models. Claude Opus 4.7 leads on coding benchmarks (SWE-bench: 74.2% vs 65.8%, HumanEval: 96.1% vs 94.5%) and agentic tasks (TAU-bench: 71.5% vs 66.2%). GPT-5 is competitive on general knowledge (MMLU: 92.8%) and is priced at $30/$60 per MTok compared to Opus 4.7's $15/$75. The best choice depends on your use case — Opus 4.7 for coding and agents, GPT-5 for general-purpose tasks.

What is the pricing for Claude Opus 4.7?

Claude Opus 4.7 API pricing: $15 per million input tokens, $75 per million output tokens. With prompt caching, cached input tokens cost $3.75/MTok (75% discount).
