Mixture-of-Experts (MoE) models activate only a subset of their parameters for each token, dramatically reducing inference costs while maintaining quality. Among the 100 coding models we track, 0 use MoE or sparse architectures.
How MoE Works
Traditional dense transformers activate every parameter for every token. MoE models instead use a router network to select a subset of expert layers for each input. For example, a 397B parameter model might only activate 17B parameters per token - delivering the quality of a large model at the inference cost of a small one.
This architecture has been adopted by major players including DeepSeek (V3 series), Qwen (3.5 series), and Meta (Llama 4 Maverick). The trend toward MoE is accelerating as providers seek to offer better quality-per-dollar ratios.
Cost Efficiency
The primary advantage of MoE is cost efficiency. By activating fewer parameters, providers can offer lower token prices while maintaining competitive quality.
