Qwen3.6 tests reveal MTP VRAM costs outweigh generation benefits
A developer's local benchmarks on Qwen3.6 27B and 35B models indicate that Multi-Token Prediction (MTP) causes degradation and excessive VRAM usage compared to ngram-mod. Tested on a dual-GPU setup using Unsloth, the results highlight that the hardware trade-offs for MTP are not worth it for memory-constrained environments.
// ANALYSIS
Speculative decoding techniques like MTP look great on paper but often fail the practicality test for local LLM users trying to maximize model size on limited hardware.
- –MTP's extra memory overhead makes it unviable for typical dual-GPU (16GB+12GB) setups that need exact VRAM fitting.
- –Standard ngram-mod provides a better balance of generation speed without the severe memory penalty.
- –The tests confirm that speculative decoding on MoE models can sometimes hurt actual token generation speed rather than improve it.
