The most interesting part for me is where @karpathy describes why LLMs aren't able to learn like humans. As you would expect, he comes up with a wonderfully evocative phrase to describe RL: “sucking supervision bits through a straw.” A single end reward gets broadcast across

Oh this is cool. Might be harder to do if you don’t own inference cuz you’re paying margins on it. Seems like a natural language APIs endpoint with reasoning baked in on the API side. This makes sense to me since X knows X best, so it’s great to offload the reasoning load of how

when you click an AI tool, it sends in the prompt via URL param and opens the AI tool in a new window with the input box pre-filled (this is example if you click chatgpt from example above)

Playing with @yoheinakajima 's babyagi-2o "simplest self-building autonomous agent". - Integrated Ollama - Threading - Manager https://t.co/VvZS4bDPTt ... may test asyncio next. I would like for the agents to work together efficiently. I should add resource tracking next.
