In the last week I created ProfanityAPI, a fast and open-source tool to filter toxic user-generated content. ◆ Much faster than AI ◆ Pretty damn accurate ◆ 100% free and open source Built with Next.js and Upstash, I'm very happy with the result. →

@nextjs @upstash Please support hitting the ENTER key to submit the text input form on the website homepage. I literally thought the website or API was broken until I realized it ignored the ENTER key entirely and required me to click the "Profanity check" submit button.

ELON: CHINA HAS THE BEST OPEN SOURCE AI MODELS RIGHT NOW “The best open source models are generally from China, which is bizarre. I think the second best one, or maybe it’s better than second best, is Grok 2.5. The open source model is actually very good, and we will continue to open source our models.” Source: The All-In Podcast
