What is Claude Opus 4.7?
Claude Opus 4.7 is the flagship Claude model for hard, multi-step work. Anthropic’s migration guide says it is highly autonomous and performs exceptionally well on long-horizon agentic work, knowledge work, vision tasks, and memory tasks. The same guide also notes that it supports the same major feature set as Claude Opus 4.6, including 1M-token context, 128K output tokens, adaptive thinking, prompt caching, batch processing, the Files API, PDF support, vision, and the full set of server-side and client-side tools.
Main Features of Claude Opus 4.7
- Adaptive Thinking: Automatically allocates more “thinking” time to complex problems while delivering fast responses to simpler ones.
- Advanced Agentic Capabilities: Excels at orchestrating multi-tool workflows, maintaining memory across sessions, sustaining long-running tasks, and recovering gracefully from errors.
- Production-Grade Coding: Plans carefully, operates reliably in large codebases, self-corrects, and delivers higher-quality code with fewer iterations.
- Enhanced Vision & Multimodal: 98.5% on XBOW visual-acuity benchmark (vs. 54.5% for Opus 4.6); improved interpretation of complex diagrams and chemical structures.
- Enterprise Reliability: Strong performance on spreadsheets, documents, slides, and multi-day projects with consistent context retention.
Performance Benchmarks of Claude Opus 4.7
Anthropic and third-party evaluations confirm Opus 4.7’s gains across coding, agentic workflows, visual reasoning, and enterprise tasks. Here are the headline numbers:
Here are the standout results:
- 93-task internal coding benchmark: +13% resolution rate over Opus 4.6; solved 4 tasks that neither Opus 4.6 nor Sonnet 4.6 could complete. Faster median latency and stricter instruction-following.
- CursorBench: 70% success (vs. 58% for Opus 4.6) — a meaningful jump in autonomous coding capabilities.
- Rakuten-SWE-Bench (production-level software engineering): Resolves 3× more tasks than Opus 4.6, with double-digit improvements in Code Quality and Test Quality.
- Internal research-agent benchmark (six modules): Tied for top score at 0.715 overall; best long-context consistency. General Finance module: 0.813 (vs. 0.767 for 4.6).
- Visual-acuity computer-use benchmark: 98.5% (vs. 54.5% for Opus 4.6).
- BigLaw Bench: 90.9% at high effort level.
- OfficeQA Pro: 21% fewer errors when referencing source material.
- Factory Droids & Bolt agentic workflows: 10–15% lift in task success; up to 10% better in best cases; 14% improvement at fewer tokens with one-third the tool errors.
Claude Opus 4.7 vs vs GPT5.4 vs Gemini 3.1 Pro
| Parameter | Claude Opus 4.7 | GPT-5.4 (incl. Pro/Thinking) | Gemini 3.1 Pro |
|---|---|---|---|
| Context Window | 1M tokens | ~1M tokens | 1M–2M tokens (varies by deployment) |
| Max Output Tokens | Up to 128K+ | High (supports long outputs) | 64K+ |
| Input/Output Support | Text + high-res image; text output | Text + image; native computer use | Native multimodal (text, image, video, audio) |
| Reasoning Modes | Adaptive Thinking (dynamic) | Thinking (low/high/xhigh effort) | Thinking/High effort modes |
| API Pricing (approx.) | $5 / $25 per M tokens | $2.50 / $15 per M tokens | Lower (~$2 / $10–12 per M tokens) |
| Release Date | April 16, 2026 | March 5, 2026 | February 19, 2026 |
| Key Strength | Agentic coding & reliability | Computer use & efficiency | Multimodal & broad reasoning |
These gains translate directly to fewer iterations, lower token spend, and higher reliability in production — critical for cost-conscious teams.
Vs. Claude Opus 4.6: Clear step-change—13% better coding resolution, 10–15% higher agentic success rates, dramatically improved vision, and stronger long-context consistency. Low-effort Opus 4.7 often matches or exceeds medium-effort 4.6 while using fewer tokens.
Vs. Competitors (as of April 2026 benchmarks):
- Faster than GPT-5.4 (xhigh) on CodeRabbit harness.
- Outperforms prior Claude models and rivals or exceeds GPT-5.4 and Gemini 3.1 Pro on agentic coding, tool-use consistency, and professional knowledge work.
- Maintains Anthropic’s leadership in nuanced writing, instruction-following, and safety calibration.
Opus 4.7 is positioned as the premier choice when maximum intelligence and reliability matter most; lighter models (Sonnet 4.6 or Haiku 4.5) remain preferable for speed or cost-sensitive workloads
