    Post-trained frontier models you can own, adapt, and deploy on your terms.

    Jupiter-N

    Our sovereign post-training of NVIDIA's Nemotron-3-Super-120B, adapted for British context with stronger instruction following, agentic behaviour, safety, and Welsh language capability, without regressing the base.

    Jupiter-G

    The same Locai post-training recipe applied to Google's Gemma-4 base, lifting instruction following, safety and code while preserving general knowledge.
