@rauchg @shadcn @tailwindcss @iamsahaj_xyz Ahhh, there goes my startup idea 😊

[Marc Lou @marclou]

I just shipped a stupid simple way to track goals on @DataFast_

✍️ Add "data-fast-goal" attribute to any HTML element
🖲️ Auto-register a custom goal when the visitor clicks

I use this on my startups to know when people initiate a checkout and click the FAQ sections.

(FAQ click tracking helps me know what people are curious about, so I can rewrite the landing page copy)

gpt-oss is a big deal; it is a state-of-the-art open-weights reasoning model, with strong real-world performance comparable to o4-mini, that you can run locally on your own computer (or phone with the smaller size). We believe this is the best and most usable open model in the world.

We're excited to make this model, the result of billions of dollars of research, available to the world to get AI into the hands of the most people possible. We believe far more good than bad will come from it; for example, gpt-oss-120b performs about as well as o3 on challenging health issues. We have worked hard to mitigate the most serious safety issues, especially around biosecurity. gpt-oss models perform comparably to our frontier models on internal safety benchmarks.

We believe in individual empowerment. Although we believe most people will want to use a convenient service like ChatGPT, people should be able to directly control and modify their own AI when they need to, and the privacy benefits are obvious.

As part of this, we are quite hopeful that this release will enable new kinds of research and the creation of new kinds of products. We expect a meaningful uptick in the rate of innovation in our field, and for many more people to do important work than were able to before.

OpenAI’s mission is to ensure AGI that benefits all of humanity. To that end, we are excited for the world to be building on an open AI stack created in the United States, based on democratic values, available for free to all and for wide benefit.

OpenAI is finally Open AI

🚀 Just slashed my API response time from 12s to 3.6s (70% faster!)

The secret sauce:
• Redis caching
• Circuit breakers
• Fallback content
• FastAPI + Celery

Cached responses now hit in <10ms!
