SID AI
SID trains retrieval models that are more accurate, cheaper, and faster.
SID is an AI research company training retrieval and search models. Its first product, SID-1, is an agentic search model designed to address the problem of finding relevant information to supply context for AI systems. The company states that SID-1 doubles embedding-only accuracy and outperforms frontier models on complex search tasks, reporting 1.9x better recall and 24x faster performance.
SID-1 is positioned as a search model rather than a general-purpose assistant, with the company focused on training models that connect intelligence to external information. The homepage describes ongoing work on training SID-1 using reinforcement learning rollouts at scale.
SID is a team based in San Francisco and Zürich. Access to SID-1 is offered through a waitlist, with no pricing, plan tiers, or trial details provided on the page.
