Qwen3-8B’s prompt-processing time reportedly halved
The user says adding an approximation model cut processing time in half while preserving similar output, without modifying Qwen3-8B itself.
TLDR
A user reports applying a later-layer key-value (KV) approximation technique to Qwen3-8B, describing it as the mechanism DeepSeek-V4.1-Flash calls “Encoder-Decoder.” They say it halved prefill time—the time spent processing a prompt before generating a response—with similar output. According to the user, the approach adds an approximation model rather than changing the original model.
