TL;DR AI
2 min readKey summary
EAGLE team released EAGLE 3.1, an update to speculative decoding focused on reducing attention drift.
It adds FC normalization and post-norm hidden-state feedback to improve robustness across prompts and long contexts.
The upgrade is backward-compatible with EAGLE 3 checkpoints and integrates with TorchSpec and vLLM.
Overall, EAGLE 3.1 aims to make LLM serving and inference more stable and reliable in real-world workloads.
