Data centers dominate AI, but they're hitting physical limits. What if the future of AI isn't just bigger data centers, but local intelligence in our hands? The viability of local AI depends on intelligence efficiency. To measure this, we propose intelligence per watt (IPW):

i cannot overstate how absurdly impressive openai’s rl infra is the people working on it clearly view it as art and probably forget they get paid if you like rl, there’s really no better place on earth to work on it

Not true. Despite speculation, this is not a new change to our terms. Model behavior remains unchanged. ChatGPT has never been a substitute for professional advice, but it will continue to be a great resource to help people understand legal and health information.

We’ve sent LLMs to med school; the next frontier is residency. It feels like LLMs in the health domain are very book-smart. Beyond the headline scores on MedQA-style benchmarks, recent studies show that models perform roughly on par with medical students but fall short of

LLMs are becoming more capable in health, and we need to think of safe ways to make use of them. In our recent AMIE work, we envision using LLMs to directly scale the physician. We imagine a setting where a physician deploys tens-hundreds of LLMs to gather patient information

When we put lots of text (eg a code repo) into LLM context, cost soars b/c of the KV cache’s size. What if we trained a smaller KV cache for our documents offline? Using a test-time training recipe we call self-study, we find that this can reduce cache memory on avg 39x
