OpenAI's former CTO just open-sourced Inkling, a DeepSeek-V3-inspired model

Mira Murati, OpenAI's former CTO, has a new company called Thinking Machines Lab — and it's open-sourcing its first model. Inkling is a general-purpose model with 975 billion total parameters, though only 41 billion are active per token. It handles text, images, and audio, and has a maximum context of 1 million tokens.

The model was trained from scratch, but its mixture-of-experts (MoE) architecture takes a lot of inspiration from DeepSeek-V3. Early post-training also leaned on data generated by open models, including Kimi K2.5. The full weights are up on Hugging Face, released under...
