Summary

Gemma 4 now features Multi-Token Prediction (MTP) drafters, enhancing inference speed and efficiency. This update aims to improve performance across developer workstations, mobile devices, and cloud environments.

Key Takeaways

Google introduced Multi-Token Prediction (MTP) drafters for Gemma 4, achieving up to a 3x speedup in inference without compromising output quality.
Speculative decoding allows the MTP drafter to predict multiple tokens simultaneously, significantly reducing latency during token generation.
Developers can enhance responsiveness and performance for applications by pairing Gemma 4 models with MTP drafters, enabling faster outputs on consumer-grade hardware.
The implementation of MTP drafters maintains identical reasoning and accuracy as the primary Gemma 4 model while delivering results more quickly.
