Google optimizes Qwen 3.5-397B MoE on Ironwood TPUs for 4.7x speedup

By PulseAugur Editorial · [1 sources] ·

Google has optimized the Qwen 3.5-397B Mixture-of-Experts (MoE) model to run on its Ironwood Tensor Processing Units (TPUs). This optimization, achieved using JAX and Pallas, resulted in a 4.7x speedup for prefill workloads. The development addresses challenges with hardware sharding limits, enabling more efficient serving of large models. AI

IMPACT Demonstrates significant performance gains for large MoE models on specialized hardware, potentially lowering inference costs and improving deployment efficiency.
