I have been working with Anthropic Opus 4.5 for a few days and it does edge out Gemini 3 Pro and ChatGPT 5.1 as a sort of 'technical work companion'. I don't use it to write code in the Claude Code sense but I do bounce ideas off it and ask for suggestions. ( I am basically

Performative nonsense. By 19 hours of no sleep you are as effective as a drunk person. By 24 hours executive function degrades by 20-40%. You’d be way more effective if you slept for 8 hours and worked the other 28 then working 36.

I want to especially thank Mistral AI for releasing the base models for Mistral 3. Fewer companies are sharing base models and this opens many use cases from custom instruct to non-instruct cases

Another AGI moment courtesy of Anthropic I am working on the stack that I use to communicate with Opus ( so Opus can read the code for that stack ). While working through a request Claude unprompted, decided an additional tool would make a task easier, and decided to write

I've put together an overview of the local LLM stack I use that leverages Parallax Gradient and a bunch of tooling I've built from scratch - primarily to learn more about models but also to be able to configure them for agentic use. Please let me know you think. ( synthetic
