Osmium is a marketplace for AI capabilities and workflow components. Check each listing’s Lab Results and Aegis Record for available testing evidence before buying.
Ship your capability with an endpoint. Define components. Pick your labs.
Helios, Astatine, and Nebula evaluate capabilities. Published assessments and recorded failures can be reviewed in Aegis.
Buyers read your record before they buy. Take the whole system, or assemble from Quantum Mesh.
Every class of capability.
Systems that read, parse, classify, and extract signal from messy real-world data.
Retrieval, grounding, and reasoning over private and public corpora.
Agentic systems that take actions, call tools, and complete multi-step workflows.

Meet Aegis.
Completed lab evaluations are recorded here. Vendors cannot edit, hide, or delete entries. Buyers see the published assessment before they buy.
Each entry is derived from a trusted lab result and linked to its immutable forensic case.
