AI / Deriva Series / Model
Deriva-1.
Our lead-priority model: an extensive finetune of Qwen3.8-27B built to be the dependable, everyday model in the lineup, and the model Kova runs on.
Overview
Deriva-1 is an extensive finetune of the new Qwen3.8-27B model. We targeted two problems in the base model specifically: overthinking and censorship. Training used high-quality synthetic data over LoRA and QLoRA runs; internal benchmarks from those runs show a 7-point improvement in browser control over the base model, the capability Deriva-1 needed to work inside Kova.
We also added OMEGA, an experimental reasoning mode that gives the model a substantially larger thinking budget than our other modes. In internal testing, OMEGA sometimes improved results by 4x to 9x over what our xHigh mode produced on the same tasks.
It also introduced problems later versions intend to fix: overthinking, degraded performance over long tasks, and degraded performance on animation and UI design, where the model would talk itself into believing an output looked “good” instead of asking the user.

Benchmark runs are not finished. We would rather leave this table empty than publish numbers we can't stand behind, so every score below is marked N/A until that changes.
| Benchmark | Deriva-1 | Qwen3.8-27B (base) | Comparison |
|---|---|---|---|
| General reasoning | N/A | N/A | N/A |
| Coding | N/A | N/A | N/A |
| Browser control (Kova) | N/A | N/A | N/A |
| Long-context retention | N/A | N/A | N/A |
| Safety / refusal balance | N/A | N/A | N/A |
The internal 7-point browser-control improvement and the 4x–9x OMEGA uplift mentioned above are early internal readings from training runs, not finished, reproducible benchmark scores. Treat them as directional until we publish real numbers.
