才发现这个 repo 就是扒了这个 API https://t.co/ilz76TNgQ8,而且它扒的还是旧版 v1(Free Version)
新版 v2 更强大,有 Images, HD videos(我看了一下比 gif 强),我试了一下,视频质量很高,还有一个 Muscle Visualizer,一个组件来高亮不同的肌肉部位,很有想法。V2 的免费额度也很高,All free plans include a limit of 1,000 requests per hour per API key,视频另算。感觉一般的小应用加点缓存也够用了。
我现在发现卖这种小众服务其实还是很有需求的啊,比如这种健身的 API,几乎没有啥竞争对手吧,当你数据质量高的话,那几乎是垄断的。这个服务也卖一次性 data,一次性可以全部下载,600刀,数据量也不大。
A senior Anthropic engineer just dropped 11-page PDF on "Loop Engineering" for agentic systems.
The shift: you stop prompting the agent. You build the system that prompts it instead.
Schedule → Discover → Build → Verify → Repeat
Every loop runs one turn, five moves:
• Discovery: it finds its own work - failing CI, open issues, recent commits - instead of being handed a list.
• Handoff: each task gets an isolated git worktree so parallel agents don't collide.
• Verification: a second agent, told to assume the code is broken, reviews the first. The "thing that can say no."
• Persistence: results get written to disk, never left in a context window that gets flushed.
• Scheduling: an automation wakes it on a timer. That's what makes it a loop.
The key insight: an agent grading its own work always praises it.
This 11-page PDF changed how I'm building agentic systems today.
Read it now, then explore the article below.
I recently spent a month in Asia, including 10 days in China, where I met with senior policy makers in several countries, and I found that over the past few months, there has been a big shift in the world order. I share my perspective in my latest article.
As always, I welcome your questions and thoughts.
