Qwen3.8-27B for NInfer

This model card is the version-controlled source for neroued/Qwen3.8-27B-NInfer.

The repository contains Qwen3.8-27B converted to the native NInfer .ninfer artifact format. The artifact is intended only for NInfer; it is not a Transformers checkpoint, Safetensors distribution, or GGUF file.

Artifact

Field	Value
Filename	qwen3_8_27b.ninfer
Size	18,210,531,328 bytes (16.96 GiB)
SHA-256	eec39564993d6e9c7d5e383382a760f093465c9d163ec9a1bd6b80199514bf3e
Container version	2
NInfer model ID	qwen3.8-27b
NInfer weights ID	groupwise-int
NInfer target key	qwen3_8_27b
Stored objects	1,124 (1,118 tensors and 6 resources)

The Text body uses the registered Q4/Q5/Q6 groupwise allocation, while the token embedding and full output head use W8G32_F16S. The file also contains the registered Vision, MTP, proposal-head, tokenizer, chat-template, generation, and media-processor objects required by NInfer.

Requirements

• NInfer revision 5232055 or later, built from source;
• 64-bit Linux;
• NVIDIA GeForce RTX 5090 (sm_120a);
• CUDA Toolkit 13.1 or newer.

NInfer does not provide an install target or packaged binary. See the repository README for source-build dependencies.

Supported use

The artifact supports:

• text generation in thinking and non-thinking modes;
• image, multi-image, video, and mixed multimodal messages;
• MTP speculative decoding with draft windows from one to five;
• BF16 and INT8 group-64 KV cache;
• CUDA Graph decode and compatible-prefix reuse;
• startup-bounded small-scale concurrent serving with true batched decode;
• the NInfer CLI;
• OpenAI- and Anthropic-compatible serving.

Limits

• The artifact is accepted only by NInfer revision 5232055 or later and the matching registered target.
• NInfer executes on one RTX 5090 and one CUDA device, with a startup-fixed capacity of 1–8 active requests per Engine.
• It does not provide large-scale or preemptive continuous batching, priority/QoS scheduling, multi-GPU execution, CPU/GPU offload, or distributed serving.
• Context allocation is subject to GPU memory and the selected KV-cache type.
• NInfer does not execute generated tool calls.

The local source configuration, tensor index, frontend resources, and published CRC32 inventory were checked against the canonical Hugging Face source revision above before conversion publication.

The artifact identity, summarized object inventory, and conversion provenance are published in artifact-manifest.json. The exact storage contract is maintained in the Qwen3.8-27B artifact reference.
