metaphor.systems is now publicly available! Metaphor is a search engine based on generative AI, the same sorts of techniques behind DALL-E 2 and GPT-3 1/

We think our next SF compute cluster is the largest h100 cluster in the world that can support bursts right now It's 1k h100s coming in March, and it can do bursts as short as 3 months

Do you have high-risk AI research ideas that are too speculative to be funded by existing institutions? We’re considering granting some of SF Compute’s capacity to a small number of interesting projects, on the order of 100s-1000s of H100s. We’re excited by risky ideas that

Hey friends, @sfcompute now offers managed Kubernetes. When you buy on SFC, you now get a k8s cluster by default with near instant spin-up time & far better reliability than we've ever had before! Still lots of limitations, but we're excited about this!

We’re releasing Wanderer 2 today! It learned a much fuzzier search function than Google, so you can search in very abstract terms. We put lots of examples on the website, and we’re serving the model live so you can experiment with your own searches: metaphor.so

Today we’re releasing Wanderer 2, a large language model trained to search over the 2.5 million pages that have been posted to Hacker News! You can play with it here: metaphor.so

Very excited for this new cluster. Big enough to train R1, but it's running our combinatorial auction so the prices should be rational

Hey friends, we're excited to announce that an additional 2,000 H100s will be added @sfcompute's on-demand market. It's the largest* interconnected cluster, from any provider (including hyperscalers), that you can get on a per hour basis. You're not locked in with San Francisco
