Released July 2025262K context≈ 196,608 words30B params

A focused coding specialist that punches above its weight — the 30B total parameters mask an efficient 3B active parameter design, meaning it runs lean without sacrificing much depth. It handles code generation, debugging, and technical reasoning with a methodical style, following instructions closely and producing structured outputs. The sparse activation means faster inference, though very long or highly abstract reasoning chains may show more strain than denser models of similar size.

Glossary

Active Parameter DesignA model architecture where only a subset of parameters are used for each token, reducing computational cost while maintaining model capacity.Code GenerationThe ability of a model to write, complete, or suggest programming code based on prompts or partial code input.InferenceThe process of running a trained model to generate predictions or outputs from new inputs.ParametersThe learned numerical values in a model — more parameters generally means more capacity but higher compute cost.ReasoningThe model's ability to work through multi-step logical problems and provide justified answers rather than just pattern-matching.Reasoning ChainsA sequence of logical steps a model follows to work through a problem methodically rather than jumping directly to an answer.Sparse ActivationA technique where only a subset of a model's parameters are used for each input, reducing computational cost while maintaining performance.Structured OutputsThe model's ability to generate responses in organized, predictable formats like JSON or XML rather than free-form text.Technical ReasoningThe capacity to work through complex logical problems, debug issues, and apply domain-specific knowledge systematically.
