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…





A small thank you to everyone using Claude: We’re doubling usage outside our peak hours for the next two weeks.









Since December my primary coding development has shifted back to the CLI. I primarily use copilot CLI for my day to day development, I still have a claude max plan and I occasionally use claude code as well. I use VS code to look at diffs of the code but haven't written much by hand in ~1.5 months. I used big VS the other day to do some advanced multi threaded debugging, but I rarely open it now. PS: I have unlimited tokens.
