From Mixture of Experts to Mixture of Agents with Super Fast Inference - Daniel Kim & Daria Soboleva
Jun 27, 2025 · 53:15
Daria Soboleva and Daniel Kim of Cerebras explain how Mixture of Experts (MoE) architectures enable scaling large language models efficiently by replacing monolithic feedforward networks with specialized experts, a technique used by GPT-4 and Claude. They then introduce Mixture of Agents (MoA), which combines multiple LLMs with custom prompts to outperform frontier models like GPT-4o on complex tasks, reducing a 293-second reasoning problem to 7.4 seconds using Cerebras' ultra-fast inference. The workshop guides participants to build their own MoA system, configure agents for bug fixing and performance optimization on a Python function, and achieve scores up to 120/120. Daniel details Cerebras' wafer-scale chip with 900,000 cores and distributed memory that eliminates memory bandwidth bottlenecks, enabling linear scaling and 15.5x faster inference on Llama 3.3-70B versus GPUs. Daria discusses ongoing research in diffusion models and sparsity, while Daniel notes plans for multimodal APIs and LoRA fine-tuning support.
