我们的通用设计 Agent 拿到了 Slides 榜第一，Elo 1316。下次你要做幻灯片时可以试试我们（我们也能做社交媒体、海报和视频）
Playyy by @Playyy_ai places 1st overall in our Slides Arena with an Elo of 1316, marking a major step change in Slides (Proprietary Harness) capability.
The model places 1st in 3 of our 8 subcategories, including Corporate, Educational, and Marketing prompts. On the overall leaderboard, Playyy leads with a 75 point Elo gap over @tryModa, Manus 1.6 by @ManusAI, and Claude Opus 4.6 (PPTX) by @Anthropic.
Unlike Agentic Slides, Proprietary Harness Slides tests harnesses owned by external builder providers (i.e. Gamma, Manus) via their API capabilities rather than specific model capabilities from a model lab (OpenAI, Meta). We include Claude Opus 4.6 with the PPTX skill as a baseline reference.
Huge congrats to the @Playyy_ai team on this achievement!

Started using this yesterday, can highly recommend!
刚刚 HeyDeer.ai 的 code review 在 GitHub 的 ReviewBench 上的精确率（precision）拿到第一。
大家之前尝试用 AI 做 code review 时如果发现 loop 收敛不了，代码改得越来越臃肿，很大程度上是 precision 低导致的
PNGDeer 现在支持 jpg 了（每日后悔项目名+1）。现在 png, jpg, webp 都支持了且全部优于 TinyPNG 和每个格式对应的各种开源压缩算法。
欢迎使用和 star: github.com/heydeer/pngdeer

写了篇文章介绍 precision 的重要性：heydeer.ai/blog/highest-prec…
另外 HeyDeer 的 recall 最近也优化了非常多
之前反馈的 @posthog Support 功能的问题竟然一天就修好了。感谢 @veryayskiy！
接下来可以把所有项目的 Intercom 都迁移到 PostHog 了 ;-)
感觉小项目的客服系统用 @posthog 的 Support 功能就足够了，比 Intercom 便宜很多。
缺点是官方 widget 功能比较弱，但是这都不是问题，因为 PostHog 的 API 非常好用，想要啥样的 widget 和 AI 说一下，几分钟就能做好 😂

HeyDeer: Get precise, low-cost AI code reviews for every pull request

pngdeer 现在支持 WebP 了（还是低估了 AI，早知道就该叫 imagedeer...）。效果依然比 TinyPNG 和其他开源项目更好。heydeer.ai/open-source/pngde…
之前写过一篇博客：zihua.li/blog/ai-raises-the-…
当时很多人认为 AI 会给经验少的人更多机会：年轻人跟得上新工具，老程序员可能守着"古法编程"不放。
后来实际工作发现，大家适应 AI 的速度都比想象中快。会用 AI 拉不开差距，真正拉开差距的还是判断力。

8 months ago we stopped reviewing most of our PRs.
AI writes nearly all our code. Nobody can keep up, so we stopped trying.
HeyDeer reviews every PR and approves the low- and medium-risk ones. Humans only see the risky ones.
Production outages from a merged bug since: 0 🦌
Claude writes about 90% of Claude Code's code.
From June to September, merged PRs more than doubled while the share reverted fell by more than 40%.
We wrote about how we changed code review to get there, and how to adopt it:

最近 Claude 分享了他们团队内部是怎么做 code review 的，和我们一直在实践的方式非常接近。正好借这个机会，简单聊聊我们是怎么用 AI code review 工具来提升内部开发速度和代码质量的 👇

效果最好的 PNG 压缩器已经开源啦！欢迎 star 和反馈 💗: github.com/heydeer/pngdeer
同质量压缩率比 TinyPNG 好 8%-12%，超过其他所有开源的压缩器。可以直接浏览器上测试: heydeer.ai/open-source/pngde…
