Has anyone gotten TevunahAi/Qwen3.5-27B-TevunahAi-GPTQ to work with vllm
On April 20th, someone in the LocalLLaMA community asked a question that carries the specific weight of someone who has already tried and failed: has anyone gotten TevunahAi/Qwen3.5-27B-TevunahAi-GPTQ to work with vllm? The model in question is a GPTQ-quantized, 27-billion-parameter fine-tune of Qwen3.5, released by TevunahAi on Hugging Face. The question implies a gap that is common in this ecosystem — a model exists on the hub, it looks deployable, someone tries to load it under vllm, and something breaks. Maybe a configuration mismatch, maybe a GPTQ kernel compatibility issue, maybe an architecture tag that vllm doesn't recognize. The thread's low score suggests the community either didn't know the answer or didn't try. Neither of those is reassuring. As of now, no public resolution has been documented.
If confirmed as a genuine compatibility wall, here is what this means. vllm has become the de facto serving backbone for production local LLM deployments — if a model can't run there, it effectively doesn't exist for a large class of practitioners who have standardized on that stack. TevunahAi's fine-tune may be technically interesting, but a 27B GPTQ model that won't load under vllm is a model that sits on the hub and accumulates no real usage. The second-order effect is quieter but more corrosive: it discourages fine-tuners from building on quantized Qwen3.5 derivatives if the serving story is unclear. For TevunahAi specifically, a single compatibility fix or a documented workaround published in that thread would unlock deployment for everyone who reads it — the gap between "broken" and "working" here is probably narrow, which makes the silence around it more puzzling.
Watch for a follow-up comment in the original LocalLLaMA thread that either documents a working vllm configuration or identifies the specific error — that single reply would shift this from background noise to a useful how-to that the rest of the community could act on immediately.
