Microsoft

A company that occupies three roles this dataset keeps apart. It creates model families, through Microsoft AI, which builds the MAI line, and through Microsoft Research, which publishes the Fara line; those are the only Microsoft records treated as models. It ships Microsoft Copilot, which is a product and is recorded as one. It operates Microsoft Foundry, which is a serving platform and is recorded as one. A model appearing in Microsoft Foundry is a deployment fact and never evidence that Microsoft created it.

Releases

Every release recorded for Microsoft, current and legacy alike. Filter by lifecycle status; the choice is kept in the page address so it survives a reload or a shared link.

Showing all 8 releases.

Products

Products this organization ships, kept separate from the models themselves. Each states how it relates to the models it draws on.

Serving platforms

Where these models are reached. A platform is labelled with who operates it: the fact that this creator runs one of its own does not make it the creator of every model served there.

Recent changes

Recorded lifecycle changes to this creator's releases, newest first. Each links to the release it changed and to the primary sources behind it.
