Karpathy 的实战评价比跑分更有说服力——做复杂编程或长任务自动化的开发者，看完会重新评估自己的 AI 助手上限。
Andrej Karpathy 对 Claude Fable 5 给出高度评价，称其不仅在跑分上全面 SOTA，更在质感上实现了重大版本升级。他指出，模型能直接理解并执行更野心的任务，无需反复引导，任务越长越难，优势越明显。Karpathy 甚至表示“从没这么想过直接不看代码”，但提醒生产环境仍需谨慎。他认为这标志着软件需求将大幅增长，用户可以自由构建解释器、可视化工具、仪表盘等定制应用。

The benchmarks are great and it's SOTA on everything by a margin but I'll add that *qualitatively* also, this is a major-version-bump-deserving step change forward (imo of the same order as Claude 4.5 was in November), peaking especially for long problem-solving sessions on very difficult problems. You can give it a lot more ambitious tasks than what you're used to, the model "gets it" and it will just go, and it's never felt this tempting to stop looking at the code at all (but don't do this in prod!). The model still has quirks that people will run into and the safeguards are configured to be a little too trigger happy for launch, which can hopefully be tuned over time. I feel a lot of things changing as working software increasingly comes out on a tap. The Jevon's paradox kicks in and I feel my own demand for software growing substantially. You can ask for anything - explainers, visualizers, dashboards, bespoke single-use apps (e.g. a full wandb that is hyper-specific just for your project), you can 10X your test suite, auto-optimize code, run giant research projects with custom HTML for the results, anything! "Free your mind" (Matrix ref). Really looking forward to all the things people build! 🔗 View Quoted Tweet 💬 1 🔄 0 ❤️ 0 👀 260 📊 1 ⚡
