Claude Opus 4.7 gains but trails Mythos

A Reddit post shares a benchmark screenshot for Claude Opus 4.7 and frames it as a major jump in coding, vision, and long-horizon autonomy. The key question is whether it is close to Anthropic’s Mythos Preview. Based on Anthropic’s public Glasswing and Mythos materials, Mythos is still the stronger frontier model on the hardest coding, browser, and security-oriented evaluations, so Opus 4.7 reads more like a practical flagship step-up than a true Mythos match.

// ANALYSIS

Hot take: this looks impressive, but I would not treat the headline numbers as proof that Opus 4.7 has caught Mythos.

–Anthropic’s public Mythos materials already show Mythos ahead of Opus 4.6 on SWE-bench Verified, Terminal-Bench 2.0, GPQA Diamond, Humanity’s Last Exam, BrowseComp, and OSWorld-Verified.
–That matters because those are closer to the kind of agentic and reasoning-heavy work where Mythos seems to be designed to separate itself.
–If the screenshot is comparing different harnesses, tool budgets, or internal evals, the percentages are not apples-to-apples.
–My read: Opus 4.7 may be the better product for broad rollout, latency, and cost control, while Mythos remains the more capable frontier model for the hardest tasks.
–So yes, Mythos can very plausibly have better metrics, and the public Anthropic data already suggests it does in the benchmarks that matter most.
