This article is a summary based on official documentation.

Overview

Anthropic released Claude Opus 4.7 on April 16, 2026. Pricing stays the same as Opus 4.6 ($5 / $25 per MTok), while delivering broad improvements across coding, vision, and instruction following. Model ID: claude-opus-4-7. Available on Claude.ai, Claude Code, the Claude API, Amazon Bedrock, Google Cloud Vertex AI, and Microsoft Foundry.

Key improvements

  • Software engineering — on long-running agent tasks, prior models tended to drift from initial instructions and loosen constraints over time. Opus 4.7 holds strictness and consistency over extended sessions. 10–14% average improvement over Opus 4.6 on major coding evals.

  • High-resolution visual understanding — processes up to 2,576 px (~3.75 megapixels) natively, a 3× resolution jump over prior Opus. Internal visual accuracy eval: 54.5% → 98.5%. Makes chemistry diagrams, circuit schematics, and UI screenshots usable.

  • Literal instruction following — earlier models inferred intent and occasionally abbreviated or skipped steps. Opus 4.7 is tuned to follow instructions literally — good for checklist-heavy workflows with strict formatting or forbidden conditions.

  • Filesystem-based memory — more reliable cross-session workflows where prior-session decisions and notes are left as files and picked up by the next session.

  • Document analysis citations — 21% fewer citation errors. BigLaw Bench: 90.9%. Finance Agent: state of the art.

New capabilities

  • xhigh effort level — a new level between high and max for finer control over reasoning depth vs. latency. Particularly impactful in multi-turn agent setups.

  • Task Budgets (API, public beta) — guides per-task token spend so agent runs don’t drift over budget.

  • /ultrareview in Claude Code — a deeper, stricter review session than /review that reads through changes and flags bugs and design issues.

Notes

  • New tokenizer — Opus 4.7 ships with an updated tokenizer; the same text can map to 1.0–1.35× more tokens than 4.6. Re-check token usage estimates and budgets.
  • More thinking at higher effortxhigh and high levels consume more thinking tokens in multi-turn agent setups. Pair with prompt caching (ENABLE_PROMPT_CACHING_1H) to manage cost.
  • Safety profile — Anthropic reports overall safety profile comparable to Opus 4.6, with improvements in honesty and resistance to prompt injection attacks.
