MiniMaxAI drops MiniMax-M3: 428B params, only 23B active

A massive 428B-parameter model that activates just 23B per token...

Deep Dive

Minimax m3 weights are out! It has ~428B parameters and ~23B activated parameters.

Key Points
  • ~428B total parameters, only ~23B activated per inference via MoE architecture
  • Weights openly released on Hugging Face for download and fine-tuning
  • Efficiency gains allow serving a 400B+ scale model with far lower compute than dense alternatives

Why It Matters

MiniMax-M3 offers frontier-scale AI capability with a fraction of the compute cost, democratizing access.
