THE MODEL CATALOG / 12 SPECIALISTS

Purpose-built
by design.

Choose a focused model for the work at hand. Each public ID maps to a specialist capability, from precise code edits to language-aware engineering.

The catalog is pre-launch. These specialist IDs are profiles of shared model infrastructure, not a claim that each ID is a separate set of model weights.

01 / FUNCTIONAL SPECIALISTS

Models for the
agent workflow.

Focused on specific steps in a technical workflow: editing, retrieval, compaction, classification and routing.

02 / LANGUAGE SPECIALISTS

Engineering in
its own language.

Specialists tuned to the conventions and constraints of six software-engineering languages.
