Exa
“Exa spent five years building what they call 'perfect search' — crawling 500 billion URLs, training custom embedding models on hundreds of H200s, and creating the fastest search API in the world at sub-200ms latency. The problem is they built the most sophisticated shovel factory right as the gold rush pivoted to a different mountain: OpenAI's o3 reasoning models can now synthesise answers from first principles without needing to crawl anything at all.”
