His hypothesis: Opus 4.7 is Mythos preview distilled down and deployed on faster hardware, rather than a fundamentally new model.

On SWE-bench Pro (the main software engineering benchmark): 53.4% (4.6) → 64.3% (4.7) → ~75% (Mythos). A +10.9% improvement that lands almost exactly halfway. - The same halfway pattern appears across multiple benchmarks. Nick finds this suspicious — genuine independent model improvements rarely produce such mathematically clean gaps. It suggests intentional calibration, not emergent performance. - Nick's Mythos distillation theory: Opus 4.7 is probably Mythos preview "basically just distilled, dummified down a little bit and running on a lot faster and better hardware." A smaller, faster version of the same model rather than a new architecture. - Agentic terminal coding shows a smaller step up: 65.4% → 69.4% (4.7) → 82% (Mythos). Nick thinks this is where the safety concerns from Mythos concentrate — Anthropic is reluctant to give the full agentic terminal capability to general users because this is the attack surface that allowed Mythos to compromise Chrome and multiple operating systems. - Anthropic's position on Mythos: they've described it as being like "giving kids nuclear weapons" — a model capable enough to autonomously compromise security systems. This is why they're not releasing Mythos directly, and why they're releasing a distilled version that's meaningfully safer on the agentic dimensions. - GPT/Spud model expected within days of Opus 4.7 — the competitive cycle is tight enough that significant Anthropic launches are reliably followed by OpenAI responses within a week. ## Benchmark Comparison | Benchmark | Opus 4.6 | Opus 4.7 | Mythos Preview | | --- | --- | --- | --- | | SWE-bench Pro | 53.4% | 64.3% | ~75% | | SWE-bench Verified | — | +10–11% | ~2× the gap | | Agentic terminal coding | 65.4% | 69.4% | 82% | Mythos preview figures are approximate, sourced from Nick's benchmark comparison scorecard in the video. ## Related on OpenClawDatabase - [Was Opus 4.6 Intentionally Degraded?](https://openclawdatabase.com/news/videos/2026-04-16-opus-47-dropped-4-6-quality-regression-analysis/) — Nate Herk's analysis of the quality regression that preceded 4.7 - [Claude Opus 4.7 as a 24/7 Trading Agent](https://openclawdatabase.com/news/videos/2026-04-17-claude-opus-47-trading-agent-routines/) — practical application of the upgraded model - [OpenClaw Configuration](https://openclawdatabase.com/openclaw/configuration/) — how to pin and upgrade model versions ## More OpenClaw & Claude Code news [▶ The 'Loop of Loops': A Better Mental Model for AI Agents (analysis, not a how-to) 2026-06-24](https://openclawdatabase.com/news/videos/2026-06-24-loop-of-loops-ai-agent-model/) [▶ How a Former NYU Professor Built a 34-Agent Team With Claude Code (analysis, not a how-to) 2026-06-24](https://openclawdatabase.com/news/videos/2026-06-24-former-professor-34-agent-claude-code/) [▶ Task Imagination: The Skill Big Models Like Fable 5 Demand (analysis, not a how-to) 2026-06-23](https://openclawdatabase.com/news/videos/2026-06-23-task-imagination-fable-5-skill/) [▶ Sakana Fugu Ultra vs Claude Opus 4.8: 38-Task Battle Test 2026-06-23](https://openclawdatabase.com/news/videos/2026-06-23-sakana-fugu-ultra-vs-opus-test/) [▶ Claude Code for SEO: Rank Using Your Own Search Console Data 2026-06-23](https://openclawdatabase.com/news/videos/2026-06-23-claude-code-seo-search-console/) [▶ GLM 5.2 on a Mac Studio M3 Ultra: 395GB, 12 tok/s, 74K Context 2026-06-22](https://openclawdatabase.com/news/videos/2026-06-22-glm-5-2-mac-studio-m3-ultra/) [See all OpenClaw news →](https://openclawdatabase.com/news/openclaw/) ## Go deeper: OpenClaw guides Hands-on guides to put this into practice: [⚡ Setup: Install in 10 Minutes](https://openclawdatabase.com/openclaw/setup/) [🔐 Security Hardening](https://openclawdatabase.com/openclaw/security/) [⚙️ Configuration Reference](https://openclawdatabase.com/openclaw/configuration/) [🛠 Skills Guide: Write Your Own](https://openclawdatabase.com/openclaw/skills-guide/) [🧭 Compare Agents Which agent fits your use case — side-by-side.](https://openclawdatabase.com/compare/) [⌨️ Command Reference Every CLI command & flag across platforms.](https://openclawdatabase.com/commands/) ← Back to [News digest](https://openclawdatabase.com/news/) · See also: [OpenClaw guide](https://openclawdatabase.com/openclaw/)
