## Definition

[Claude Opus 4.7](https://www.anthropic.com/news/claude-opus-4-7) is Anthropic's flagship LLM, released April 16, 2026. It narrowly retakes the lead over GPT-5.4 and Gemini 3.1 Pro on agentic coding benchmarks, ships a 1M-token context window at standard pricing, and adds new production controls: `xhigh` effort, `task_budget`, and a retooled tokenizer ([API docs](https://platform.claude.com/docs/en/about-claude/models/whats-new-claude-4-7)).

The release is notable for what Anthropic admits it is NOT shipping: in CNBC and Axios coverage, Anthropic conceded 4.7 trails 'Mythos,' an unreleased internal model, on several internal evals. 4.7 ships with real-time cybersecurity safeguards built into the weights ([system card](https://anthropic.com/claude-opus-4-7-system-card)); Mythos stays in red-teaming. It replaces Opus 4.6 as the default across Claude Code, the Agent SDK, and Managed Agents.

## Analogy

If Opus 4.6 needed a ticket and review, 4.7 writes the ticket itself, self-reviews, and reports back when the budget runs out.

## Why it's emerging now

Anthropic shipped Claude Opus 4.7 on Apr 16 — a genuine benchmark step (SWE-bench 80.8 → 87.6%) paired with an unusually public narrative about the model they are NOT shipping yet (Mythos). Developer params got pruned the same day. Community verdict split fast: 'narrowly retaking lead' vs 'token eating machine'.
