EAGLE3 is an encoder-decoder based speculative decoding method: - Extracts features from target model at specific layers - Uses feature fusion layer to compress target features - Generates draft tokens with single-layer decoder - Maps draft vocabulary to target vocabulary via d2t tensor Key changes: - Add LLM_ARCH_EAGLE3 architecture - Add EAGLE3 encoder/decoder graph (src/models/eagle3.cpp) - Add feature extraction from target model layers - Add g_embeddings handling for decoder input - Add GGML_TENSOR_FLAG_SYNC for GPU synchronization - Add --eagle3 flag for speculative-simple example - Add EAGLE3 model conversion in convert_hf_to_gguf.py |
