Strict Data Serialization (JSON)
Constraint Adherence
Scores are synthesized aggregate metrics from our local multi-turn gauntlet. Each model was evaluated using hardcore developer prompts across single-file coding syntax, agentic state-machine logic, and tool-calling execution. The final scoring weight balances native execution speed, codebase compilation quality, and absolute constraint adherence. Competitor models evaluated locally using quantized 4-bit configurations.
One model. Five corpora. Zero filler.
Zwen-Prime is a hand-fused 7B coding and reasoning model. It reasons in the open, ships the artifact, and says nothing else — the discipline of a 50k-star maintainer, distilled to a model that runs on your laptop.
DARE-TIES fusion
Five expert corpora merged via DARE-TIES into a single coherent 7B — no capability lost, no persona drift.
5-Corpus Mixture
Typed Python, step-by-step math, flawless JSON tool-calling, extended context, full-stack discipline.
Metal-accelerated
Native Apple Silicon inference through node-llama-cpp. Unified-memory matrix paths, no GPU required.
Local-first
Runs entirely on-device. Your code, your context, your prompts never leave the machine.
Built by a founder who ships.
Zwen AI Labs exists to give every engineer a world-class model that runs privately on their own hardware — no cloud, no compromise, no data leaving the machine.
