Cerebras published a technical blog detailing how to shard trillion-parameter models like Kimi K3 across multiple WSE-3T wafer-scale chips. By leveraging on-chip memory and optimized mapping, the system achieves inference speeds of 1000-2000+ tokens per second, addressing the limitation where single-chip memory cannot hold massive model weights.

    Cerebras Details Multi-Wafer Deployment for Trillion-Parameter Models

    • A single Cerebras WSE-3T chip has 44GB of on-chip memory, insufficient for trillion-parameter model weights which require terabytes.
    • By sharding models across multiple chips, Kimi K3 (3T parameters) achieves inference speeds of 1000-2000+ tokens/s.
    • The post explains strategies for fitting models into on-chip memory, mapping across chips, and handling high concurrent requests.
