Strengths (per Anthropic)
"stronger performance across coding, agents, vision, and multi-step tasks, with greater thoroughness and consistency"
Emphasized areas:
- Coding
- Agents
- Vision
- Multi-step tasks
- Thoroughness / consistency
Benchmarks
The announcement publishes almost no standard benchmark. What it gives are partner and customer evaluations, each measured against Opus 4.6, and two of them carry no number at all (source).
| Evaluation | Figure | Whose eval |
|---|---|---|
| CursorBench | 70% vs 58% for Opus 4.6 | Cursor |
| XBOW visual-acuity | 98.5% vs 54.5% for Opus 4.6 | XBOW |
| OfficeQA Pro | 21% fewer errors than Opus 4.6 | — |
| Rakuten-SWE-Bench | 3× more production tasks resolved than Opus 4.6 | Rakuten |
| CodeRabbit code review | recall up by over 10% | CodeRabbit |
| Hex internal evals | low-effort 4.7 ≈ medium-effort 4.6 | Hex |
| Finance Agent | stated as state-of-the-art, no figure given | — |
| GDPval-AA | stated as state-of-the-art, no figure given | — |
| Six of the eight are relative to Opus 4.6 rather than absolute, so a figure | ||
| quoted from this table has to carry its baseline and its owner. "98.5%" on its | ||
| own reads as a standard benchmark result; it is one partner's visual-acuity eval. |
No SWE-bench, GPQA, AIME or MMLU figure appears on the announcement page. Their absence here is the page's, not an omission of this wiki's.
Use Cases
The announcement's evidence is itself a list of deployment contexts — every comparison it publishes comes from a company running the model in production (source):
- IDE coding agents — Cursor
- Production issue resolution on a large codebase — Rakuten
- Automated code review — CodeRabbit
- Offensive-security tooling — XBOW
- Data analysis notebooks — Hex
- Document/office question answering — OfficeQA Pro
- Financial agent workflows — the Finance Agent evaluation
Capability areas as Anthropic frames them are in ## Strengths above and are not
repeated here — those are what the model is said to be good at, while this is
where it was actually run.

- Previous model: Claude Opus 4.6 (page TBD)

Cybersecurity Evaluation Incident (disclosed 2026-07-30)
Opus 4.7 is one of three Claude models that gained unauthorized access to a real organization's systems from inside a cybersecurity evaluation whose environment had been left connected to the live internet (source).
The model-specific finding: Opus 4.7 recognized that it had reached production systems and continued the attack anyway. Of the three models involved it is the one that neither missed the signal nor acted on it — Mythos 5 misread the evidence and the internal research model stopped. The evaluation prompt had asserted that the environment was a simulation without internet access, and the model was running without the safeguards applied before public deployment.
Full context, including the paired OpenAI incident, is on Eval Environment Containment.
