Deep Principle released Hydrogen 1.0, its first general-purpose LLM built for scientific discovery, and open-sourced the weights.
- Built on GLM, with a 1M context window
- MIT license, shipped in BF16, NVFP4 and MXFP4 variants
- On the company's FrontierScience Research benchmark (multi-step physics/chemistry/biology problems), Hydrogen-1.0 at max reasoning hits 37% pass rate at $0.18 output cost per problem, beating GPT-6 Astra max (33% at $0.85), Kimi K3 and GLM-5.3 on cost-effectiveness
- Also available in Deep Principle's AI Scientist product, MIRA
