Claude Opus 4.7: Frontier Agentic Coding That Holds Up Over Long, Multi-Step Runs Claude Opus 4.7 is Anthropic's flagship Opus-class model and its most capable generally available release as of April 2026. It sits at the top of the current 4.x lineup above Sonnet and Haiku, optimized for sustained reasoning across long, tool-dependent runs rather than for speed. Its strongest differentiator is agentic software engineering: it leads current non-preview models on SWE-bench Verified and SWE-bench Pro, recovers from mid-run tool failures, and self-verifies its own output. Teams running autonomous coding agents, CI/CD automation, and enterprise document workflows benefit most. Start building with Claude Opus 4.7 via the AnyAPI.ai API.

Performance

Where Claude Opus 4.7 Pulls Ahead: Agentic Coding and Fault Recovery

Claude Opus 4.7 is built for long-running, tool-dependent engineering work rather than quick single-turn responses. Anthropic reports 87.6% on SWE-bench Verified and a 10.9-point single-release jump on SWE-bench Pro to 64.3%, its clearest evidence of stronger difficult-task coding. More useful in production, the model is designed to continue executing through tool failures that would have halted Opus 4.6, recovering and adapting rather than stopping. For automated pipelines where a single failure can cascade, that robustness matters more than a marginal accuracy delta, letting teams hand off harder work with less supervision.

Benchmarks

Independent and Reported Benchmarks: Coding, Tool Use, and Vision

On coding and agentic tool use, third-party trackers align with Anthropic's framing. Opus 4.7 leads SWE-bench Pro (64.3% vs GPT-5.4's 57.7%) and posts strong tool-use scores on MCP-Atlas (77.3%) and OSWorld computer use (78.0%). On CharXiv visual reasoning it reaches 82.1% without tools. Artificial Analysis places it at 54 on its Intelligence Index, well above the median for comparable reasoning models. The clearest trade-off is web research: GPT-5.4 Pro leads BrowseComp (89.3% vs 79.3%), so browsing-heavy research agents may still favor GPT-5.4.

Technical Specifications

What the model supports

Claude Opus 4.7 accepts text and image input and returns text output; it is not a multimodal generator. It supports a 1M-token context window with no long-context premium and up to 128K output tokens on the synchronous Messages API (up to 300K via a Batch API beta header). The most consequential production detail is reasoning: Opus 4.7 supports only adaptive thinking. The older thinking.type "enabled" with budget_tokens returns a 400 error, and non-default temperature, top_p, or top_k and assistant prefill are also rejected—breaking changes to handle before migrating.

Comparison

Claude Opus 4.7 vs GPT-5.4: Which for Coding and Research Agents?

Both Claude Opus 4.7 and GPT-5.4 are frontier models teams evaluate for autonomous agents and complex engineering. They overlap heavily: strong reasoning, tool calling, vision input, and long context. The practical decision usually comes down to workload shape. Opus 4.7 is tuned for agentic coding and multi-step execution with fault recovery, while GPT-5.4 is stronger on browsing-heavy web research. Both are premium reasoning tiers, so cost sensitivity rarely separates them; capability fit on your specific task distribution does.

Choose Claude Opus 4.7 when your core workload is agentic software engineering, multi-tool orchestration, computer use, or high-resolution document and vision analysis—it leads SWE-bench Pro and Verified and recovers from mid-run tool failures. Choose GPT-5.4 when browsing-heavy research agents dominate, where it leads BrowseComp by roughly ten points and holds a narrow edge on Humanity's Last Exam with tools. For agentic coding inside Claude Code, Cursor, or custom pipelines, Opus 4.7 is the stronger default.

Limitations & Trade-offs

Where Claude Opus 4.7 (Adaptive Reasoning, Max Effort) falls short

1
Higher latency than lighter siblings. Opus 4.7 is an Opus-class reasoning model, slower than Haiku or Sonnet, and independent measurements put throughput around 81 tokens per second. In agentic loops with many sequential steps, that latency compounds, and adaptive thinking can consume many tokens. For latency-sensitive or high-volume interactive workloads, Sonnet or Haiku are better choices; benchmark inference speed on your actual task distribution, not just accuracy.
2
Breaking API changes on migration. Moving from Opus 4.6 is not strictly drop-in. Opus 4.7 supports only adaptive thinking—budget_tokens is removed and returns a 400 error—and non-default temperature, top_p, top_k plus assistant-message prefill are also rejected. An updated tokenizer can also inflate token counts by roughly 1.0 to 1.35x on identical input, so real per-task cost can creep up even though the per-token rate is unchanged. Audit call sites and re-measure spend on real traffic before switching.
3
Text-only output and no image generation. Opus 4.7 accepts text and high-resolution image input but returns text only. It cannot generate images, audio, or video. Applications needing generated visuals, speech, or synthesized media must pair it with a separate generation model. Its multimodal strength is analytical—reading charts, diagrams, contracts, and screenshots—not creative output.
4
Weaker on browsing-heavy research. On BrowseComp, GPT-5.4 Pro leads Opus 4.7 (89.3% vs 79.3%), and GPT-5.4 holds a narrow edge on Humanity's Last Exam with tools. For agents whose primary job is live web research and open-ended browsing, Opus 4.7 is not the strongest option; its advantages concentrate in coding, tool orchestration, computer use, and document reasoning instead.

Best-Fit Workloads

Where this model earns its place

01

Autonomous coding agents


Opus 4.7 is the default choice for long-horizon coding agents in Claude Code, Cursor, and custom pipelines. It leads SWE-bench Verified (87.6%) and SWE-bench Pro (64.3%), improves fault localization and failing-test interpretation, and hallucinates fewer non-existent APIs. Critically, it continues through mid-run tool failures rather than halting, which matters for CI/CD automation and hours-long async workflows where cascading failures are costly. Expect higher latency and token use than Sonnet.

02

Large-codebase and multi-day project context


The 1M-token context window—carrying no long-context premium—lets Opus 4.7 reason over entire codebases and carry multi-day project state forward without frequent compaction. This suits repository-wide refactors, cross-file debugging, and agents that must hold accumulated context across a long session. Gemini 3.1 Pro offers a larger 2M window, so extreme single-prompt context needs may point elsewhere, but 1M covers most enterprise engineering workloads.

03

High-resolution document and vision analysis


Opus 4.7 processes images up to 2,576 pixels on the long edge (~3.75MP), more than three times prior Claude limits, and reports 82.1% on CharXiv visual reasoning. This targets enterprise document work: scanned contracts, technical drawings, financial statements, and dense charts where fine print and detail defeat lower-resolution vision. It reads and interprets these documents but returns text, so it fits analysis and extraction rather than visual generation.

04

Enterprise knowledge and financial work


Opus 4.7 scores 64.4% on Finance Agent v1.1 and self-verifies its output—re-reading generated models, spreadsheets, and redlined documents against the original request before delivering. Integrators report it correctly flags missing data instead of providing plausible-but-incorrect fallbacks and resists dissonant-data traps. This suits financial analysis, research, and document generation where quiet errors are expensive, though outputs still require review for high-stakes filings.

Frequently Asked Questions

Answers to common questions about integrating and using this AI model via AnyAPI.ai

Claude Opus 4.7 is Anthropic's most capable generally available model, tuned for agentic software engineering and long-running, tool-dependent tasks. It leads current non-preview models on SWE-bench Verified (87.6%) and SWE-bench Pro (64.3%), recovers from mid-run tool failures, and self-verifies its output. It also handles high-resolution document and vision analysis and enterprise knowledge work.

Claude Opus 4.7 supports a 1M-token context window with no long-context premium, and up to 128K output tokens on the synchronous Messages API. On the Batch API it can reach 300K output tokens using a beta header. The 1M window lets it reason over entire codebases and multi-day project context without frequent compaction.

Opus 4.7 supports adaptive thinking only, letting the model decide how much to reason based on task and effort level. The older thinking.type "enabled" with budget_tokens is removed and returns a 400 error. Effort levels are low, medium, high, xhigh, and max; xhigh is a new tier between high and max, recommended alongside high for coding and agentic use.

No. Migration is not strictly drop-in. Opus 4.7 requires adaptive thinking, rejects non-default sampling parameters and assistant prefill with 400 errors, and uses an updated tokenizer that can increase token counts by roughly 1.0 to 1.35x on identical input. Audit call sites and re-measure spend on real traffic before switching.

For agentic coding, Opus 4.7 leads: it beats GPT-5.4 on SWE-bench Pro (64.3% vs 57.7%) and SWE-bench Verified, with strong tool use and computer use. GPT-5.4 leads browsing-heavy web research on BrowseComp. Choose Opus 4.7 for coding agents and multi-tool orchestration; choose GPT-5.4 when live research and browsing dominate.
