ZERO Coder.
Open-weight ambition.
Engineering discipline.
Our coding-model development initiative, exploring an open-weight direction with a deliberate emphasis on engineering and evaluation.

ZERO Coder is distinct from ZERO, the coding agent. The open-weight direction does not establish that a particular checkpoint, license or download is released.
A model.
A separate initiative.
ZERO Coder is the model-development initiative; ZERO is the coding agent. The open-weight direction is a development goal. A checkpoint, its license and a real download destination will be listed only after release validation.

authorized access path.
Follow the development agenda through Research. Any future release needs a validated checkpoint, clear license and verified distribution destination. The development direction does not provide present access to model weights.
Developer gateway Developer TermsEvaluate the work.
Before you scale.
Evaluate a model against the tasks, data and controls relevant to your environment. Our research agenda describes the work; validated results belong alongside the evidence and evaluation method.
