🧠 Core Design Philosophy

This model is built around a sharp constraint:

If a model only has 2B parameters… every neuron has to earn its place.

Key ideas:

• Prioritize coding over general chat
• Bias toward structured outputs
• Encourage step-based reasoning
• Optimize for tool-augmented environments
