80GB H100 GPU struggles with large models; MoE offers solution

A developer found that an 80GB H100 GPU, costing around $35,000 USD, was insufficient for conversational AI with large models due to latency issues. While the model might fit in memory, the computational cost per token significantly impacts response speed, making conversations feel unnatural. The developer discovered that Mixture of Experts (MoE) models, like Qwen3.6-35B-A3B, offer a solution by using only a fraction of their total parameters (3B out of 35B) per token, balancing high accuracy with manageable computational demands for conversational applications. AI

IMPACT Highlights the trade-offs between model size, computational cost, and conversational fluency, suggesting MoE architectures as a path forward for efficient AI deployment.
