Ex-OpenAI CTO Greg Brockman releases 975B parameter open-weights AI model

By PulseAugur Editorial · [1 sources] ·

Thinking Machines, a company co-founded by former OpenAI CTO Greg Brockman, has released an open-weights AI model with 975 billion parameters. This move contrasts with OpenAI's approach, which has increasingly kept its frontier models proprietary. The new model aims to provide an alternative to large Chinese LLMs and is intended for broader research and development access. AI

IMPACT Provides a powerful open-weights alternative to proprietary frontier models, potentially accelerating research and development outside of major labs.
