What happened and what to do

Published on June 3, 2026, the article compares DFlash and MTP with vLLM and llama.cpp on math, coding, and chat tasks. On Qwen3.6 27B, DFlash reaches up to 4× speedup; on Qwen3.6 35B A3B, MTP usually performs better. The results indicate that the choice depends on the model and workload.

For a company, the practical response is to test these options on its own workloads before adopting a configuration. Wendelmaques can structure an evaluation on the company's infrastructure, measure performance and costs by task, and present the findings in a dashboard to support a decision.

How the consultancy can help

Wendelmaques can diagnose the opportunity, define a comparison plan using the company's models and workloads, and implement evaluation and monitoring on its own infrastructure. Operations and scope are defined in a proposal.
