Detailed Review of SID - Other AI Software (2026)

What is SID?

SID trains retrieval models that are more accurate, cheaper, and faster. AI is giving humanity a new computer: one that can learn, reason, and act. But intelligence and skills are inconsequential without context. Context imposes the upper bound. At SID, we're training models to provide this context. To connect intelligence to the world. To provide the right context, you need to find it first: Search is an ancient problem, but we think we have an angle to solve it once and for all . SID-1 , our first agentic search model, doubles embedding-only accuracy and outperforms frontier models on the most complex search tasks.
