Two tracks. Every model, honest status.
A general line (AGPT) and a dedicated agentic line (SIA), built on one owned, from-scratch spine. Here's what's built and serving today, then the full general catalog and the agentic line.
Our 110M from-scratch decoder — the live chat brain behind StretchGPT today.
~23M from-scratch encoder. Trained and serving; the foundation for semantic search.
Three sized code specialties — trained and registered in the catalog.
Trained and measured — 95% overall, perfect tool-selection on our internal harness.
The AGPT catalog.
One AGPT architecture, sized into Mini, Pro, and Max and specialized by domain — 28 models across eight capability lanes, graduating one at a time under governed sign-off. Status is updated from the live registry.
Statuses: Live — serving now · Trained — weights trained · Planned — on the roadmap · Governed — reserved, no build without sign-off.
The SIA line.
A generational agentic line — one generalist, numbered by capability era, scoped to reliable tool-calling. The public name stays constant as the brain underneath grows from teacher-assisted to fully owned.
| Generation | What | Status |
|---|---|---|
| SIA-1.0 | Agentic generalist — trained & measured (95% overall, 100% tool-selection) | Trained |
| SIA-1.5 | Reinforcement-polished, sharper abstention, deeper harness | Planned |
| SIA-2.0 | First fully-owned brain — our weights end to end | Planned |
| SIA-3.0+ | Scaled, self-improving | Planned |
