    A new release landed for smol machines with v1.5.0. 1. CUDA support, through api-remoting. This is pretty unique work because I don't think any existing options are doing this today. This basically enabled the local <-> remote GPU support meaning you can change and end point and

    ♥️ GPT-5.6 is a major step forward for health, both at the frontier and at cost. These models push the frontier of performance per dollar, bringing the best health intelligence to all. The smallest variant, GPT-5.6 Luna, evaluated at the lowest reasoning effort, outperforms

    A lawyer friend on Legora: "Legora really helped with this latest motion, which was dense with past issues in the case. Now my paralegal says she cannot live without it. It is just too remarkable and timesaving."

    If you're wading in the swamp of churn prevention, it's already too late. The product sucks and you're just trying to move a few percentage points. The faster path to a high retention low churn is actually having a real awesome product. Everything else is a small side effect.

    We've now launched and served 40,000+ total projects @insforge! A few months ago, we were still struggling to explain what InsForge was. People didn't quite get it at first. But we kept our heads down and focused on making the developer experience as frictionless as possible.

    We ran hundreds of AI web design builds testing Opus 4.8 vs GPT-5.6 Sol. One model built better-looking pages in half the time, with half the code. It wasn't the one I expected. What I learned about slop, context rot, and why your prompts don't matter as much as your think🧵
