About SID AI

SID is building SID-1, its first agentic search model, which achieves 1.9x better recall and 24x faster performance compared to embedding-only approaches. The model outperforms frontier models on the most complex search tasks and is being trained with reinforcement learning rollouts at 1k+ QPS to surpass GPT-5. SID aims to provide context for AI by solving the search problem. The company is backed by Y Combinator, Canaan, Rebel, and General Catalyst, and includes researchers from Anthropic, Deepmind, OpenAI, and others. Based in San Francisco and Zürich, SID is currently on a waitlist for early access.
