We ship AI apps and show you exactly how. 20K+ builders following along.

















the micro1 robotics lab: real world data for intelligent models that co-exist in the physical world. we’re in-the-wild across 75 countries in 6,000+ unique environments collecting data. diverse movements, objects, and settings. the future of AI is as human as you can imagine. join us to start training robots today (link in comments).


GPT-5.4 mini and nano just dropped. @OpenAI's two new small models, different jobs. mini: 2x faster than GPT-5 mini, built for coding, computer use, and subagents nano: smallest and cheapest in the 5.4 family, for lightweight tasks

We’re introducing GPT-5.4 mini and nano, our most capable small models yet. GPT-5.4 mini is more than 2x faster than GPT-5 mini. Optimized for coding, computer use, multimodal understanding, and subagents. For lighter-weight tasks, GPT-5.4 nano is our smallest and cheapest version of GPT-5.4. openai.com/index/introduc…
