BREAKING: @OpenAI just released GPT-5.4 and it is AMAZING. We spent a week @every putting it through real engineering tasks from code reviews to planning workflows and using it inside of our @openclaw setups. The verdict: OpenAI is back in the coding race. - Its planning capability consistently beat Codex 5.3 and Opus 4.6 in head-to-head tests. It produces plans that are thorough and technically precise, and have a user focus and “human” feel that has been missing from OpenAI's previous coding mode - It reviews code with more depth than 5.3 Codex, and a much more conversational voice that doesn't make you feel dumb. - It became our go-to model in @OpenClaw: with some model-specific tweaks to the harness it's fast, intelligent, and more human. It's also about half the price of Opus 4.6. As ever, there are tradeoffs: - GPT-5.4 has a tendency to expand the task well beyond what you asked for and to call tasks done before they're finished. - In the @OpenClaw harness it sometimes completed tasks in obviously wrong ways, then lied about it. Overall though, it's my new daily driver for coding and in my Claw. Its thinking-traces produced some genuine wow moments for me. Our complete vibe check is available on @every now -> every.to/vibe-check/gpt…

Hi friends! Big news today: Helicone is joining Mintlify 🚀 3 years ago, we started Helicone out of YC W23 with a simple bet: every hype-cycle has a massive observability market, and we felt like AI was going to be even more prevalent. We knew someone needed to build the platform to ingest and make sense of it all. So we did. Years of grinding and a handful of pivots later, we built something real that customers use every single day. I spent most of that time worried about tomorrow and never really stopped to look back. But looking back now: - 14T+ tokens processed - 30k+ sign ups - 36M+ users tracked - Trending on Github last year (5.2k stars) - $1M+ ARR - Product of the week on Product Hunt That still blows my mind. So why Mintlify? In a post-AGI world, a knowledge infrastructure layer is the thing that makes the most sense for companies to invest in. Waymo didn't reinvent the roads, but still needed to learn about them. Mintlify is the information layer for agents building the systems of the future. The overlap with what we were building at Helicone was obvious. Same world, different angle. More importantly, I actually like the team and the product. That sounds simple but after talking to a dozen companies, it's rarer than you'd think. @handotdev and @hahnbeelee are both incredible and formidable founders that Cole and I really admire. Things I learned building Helicone that I think are underrated - A 5-person team can do an absurd amount if everyone is locked in. Headcount is not a moat. - If you have data at scale and need analytics, just pick ClickHouse. Don't overthink it. - The grind is real, and it's fun. But REALLY try not to be stressed when you aren't grinding. That part took me way too long to learn. - It's never too late to pivot and try new things. - Charge more for your product. What's next I'm going to be leading an engineering team at Mintlify and I'm genuinely excited about what we're building. Keep an eye on my X, because I can't wait to be tweeting about it more. Thanks to @coleywoleyyy for being an incredible co-founder. Thanks to our team, our investors, our customers, and everyone who bet on us early. And thanks to my fiancee for putting up with the chaos of startup life. That part is deeply underappreciated. And lastly, thank you @mintlify for taking a bet on the Helicone team. We are so excited for the next phase. More to come. DMs are open.
