Claude Opus 4.7 Review: Benchmarks, Features & Who Should Upgrade (2026)

Anthropic released Claude Opus 4.7 on April 16, 2026, just two months after Opus 4.6. The headline is coding: a 13% improvement on a 93-task internal benchmark and 3x more resolved production tasks on SWE-bench. But the update goes deeper — new inference tiers, a vision overhaul, and tooling upgrades that change how you work with Claude Code.

Here is everything that changed, benchmark by benchmark, and a clear verdict on whether you should upgrade.

Benchmark Results: Opus 4.7 vs 4.6

What Is New in Claude Opus 4.7

xhigh Effort Level

Anthropic added a new inference tier called xhigh that sits between high and max in the API. The intent is to give developers a cost-performance sweet spot for coding and agentic workflows: near-max quality at lower token spend. Early benchmarks from independent testers show xhigh reaching 85–90% of max-effort quality at 60–70% of the cost.

/ultrareview in Claude Code

Claude Code 2.1 ships with a new /ultrareview command. Point it at a file or directory and it runs a multi-agent scan for bugs, security issues, and anti-patterns. This is distinct from the standard inline review — it triggers a dedicated reasoning pass and returns a structured report with severity tags. Available to all Claude Code users, with auto mode for Max subscribers that handles long-running passes without manual prompting.

Task Budgets (Public Beta)

A new task budget parameter lets you cap the maximum tokens Claude can process for a specific task. This matters for agent workflows where a runaway reasoning loop can spike costs. Set a budget, and Opus 4.7 will either complete within it or surface a partial result with a budget-hit warning.

3.75MP Vision

Opus 4.7 triples the maximum image resolution from 1.25 to 3.75 megapixels. In practice this means: dense spreadsheets, high-DPI UI mockups, and multi-column PDFs now render with readable fidelity. The improvement in chart and diagram interpretation is the most immediately useful change for non-coding workflows.

What Did Not Change

• Price — $5 / $25 per million input/output tokens, unchanged from Opus 4.6
• Context window — 200K tokens, unchanged
• Availability — all existing Claude plans, Bedrock, Vertex AI, Foundry, GitHub Copilot
• General knowledge — Anthropic describes this as a coding-first upgrade, not a broad knowledge update

Who Should Upgrade

Using Claude Opus 4.7 Inside Happycapy

Happycapy's model routing layer already supports Opus 4.7. Switch to it from the model selector in any session. Because Happycapy is model-agnostic, you can run Opus 4.7 for your hardest coding tasks, GPT-5.4 for long-form writing, and Gemini 3 for multimodal analysis — all within a single persistent workspace with shared memory.

The xhigh effort tier maps directly to Happycapy's "Deep Think" mode, which lets you toggle higher reasoning effort without switching platforms or managing separate API keys.
