Contrastive decoding is a general technique for adjusting token probabilities at the decoding stage, guiding generation by computing the difference between expert and amateur distributions and applying temperature scaling or truncation, requiring no additional training.

VerifiedConstrained Decoding computes the set of valid tokens at each token step of autoregressive generation based on a finite state machine or context-free grammar and renormalizes the probabilities, mathematically guaranteeing that the output conforms to the target schema.78% similarVerifiedDecompilation is the process of restoring machine code or bytecode to a human-readable high-level language, whereas disassembly only restores code to the assembly level69% similarVerifiedThe decode phase is a memory-bandwidth-intensive operation, and overall throughput is constrained by VRAM bandwidth rather than compute.68% similarUnverifiedTechniques such as speculative decoding and KV cache optimization can reduce the computational cost per request.68% similarUnverifiedTransformer inference is divided into two stages, prefill and decode: prefill processes the entire input prompt in parallel at once and is mainly compute-bound; decode generates output tokens one by one and is mainly memory-bandwidth-bound.67% similar
