Strengths
- Leading scores on software-engineering agent benchmarks
- Exceptionally robust under tool use — rarely hallucinates tool calls
- Prompt caching meaningfully cuts cost on long-context apps
- Strong instruction following with XML-tag prompting
Limitations
- Highest-price tier in Anthropic's lineup — use Sonnet for routine work
- Latency is noticeable vs. Haiku / Gemini Flash for interactive UIs
- Vision is competent but below Gemini 2.5 Pro for document OCR
Use cases
- Coding agents (Claude Code CLI, Cursor, Zed) with tool loops
- Long-document analysis — contracts, papers, large codebases
- Research assistants — multi-step web + document synthesis
- MCP-driven workflows where reliability matters more than latency

Frequently asked questions
What is Claude Opus 4.7?
Claude Opus 4.7 is Anthropic's top-tier 2026 large language model — a 1M-context reasoning system with native tool use, vision input, and leadership on SWE-bench Verified. It is the recommended model for coding agents and research assistants on the Anthropic platform.
What is the context window of Claude Opus 4.7?
Claude Opus 4.7 has a 1,000,000-token context window with prompt caching enabled, letting developers keep large codebases or long documents in-context while amortising cost across calls.
How much does Claude Opus 4.7 cost?
As of April 2026, Claude Opus 4.7 is priced at roughly USD 15 per million input tokens and USD 75 per million output tokens on the Anthropic API. Prompt caching reduces the effective cost of stable long-context prompts.
What is Claude Opus 4.7 best for?
Coding agents, long-horizon research workflows, document analysis, and MCP-driven tool-use pipelines where reliability and reasoning quality matter more than raw latency or cost.
