unsloth / Qwen3.8-Flash-Next-GGUF

Overview

Qwen 3.8 Flash Next GGUF is a GGUF release of Qwen3.8-Flash-Next. (github.com)

The Qwen Team (Alibaba Group) trained the base model as a multimodal Mixture-of-Experts system with long-context focus. (github.com)

Unsloth publishes this GGUF pack so you can run the model in GGUF-friendly runtimes and pick a quantized build that fits your hardware. (huggingface.co)

This model generates assistant text for chat, coding, and document-scale work. It can also produce a “thinking” trace before the final answer when thinking is enabled. (huggingface.co)

What you can build

• Long-context Q&A over large notes, specs, or meeting logs
• Code help across a large repo snapshot pasted into the prompt
• Agent-style planning where the model reasons before acting
• Drafting and rewriting: memos, reports, emails, and support replies
• Structured outputs such as checklists, step plans, and acceptance criteria

Inputs

• A required user message that describes what you want in plain text.
• An optional system instruction in plain text to set rules, tone, and constraints.
• A thinking mode toggle that controls whether the model reasons before answering. (huggingface.co)
• Optional user and session identifiers (plain text) to keep separate chat histories.
• A randomness control (number from 0 to 5). Lower values give steadier answers.
• A nucleus sampling threshold (number from 0 to 1) to limit unlikely tokens.
• A top-k cutoff (integer from 0 to 100) to cap the candidate token set.
• A repetition penalty (number from 0 to 5) to reduce repeated phrases.
• A length penalty (number from 0 to 5) to bias toward shorter or longer replies.
• A maximum output token limit (integer up to 800,000) to cap response length.
• A minimum output token target (integer from -1 to 2,048) for short-answer control.
• Optional stop strings, provided as a semicolon-separated list, to end generation early.
• An optional random seed (integer) to help reproduce the same style of output.
• A sampling toggle that switches between deterministic decoding and sampling.
• A quantization toggle that prefers smaller-weight variants when available.

Outputs

The model returns generated text as the assistant’s reply.

When thinking is enabled, the reply may include an explicit reasoning block and a final answer, depending on the chat template used by the runtime. (huggingface.co)

Generation stops when it hits your stop strings or the maximum output token limit.

Limitations

The underlying checkpoint is a causal language model with a vision encoder. This Wiro interface exposes text generation inputs only, so vision features may not be available here. (huggingface.co)

The native context length is 262,144 tokens, and some setups can extend beyond that. Longer contexts need much more memory. (huggingface.co)

This GGUF repo includes many quantization variants with large on-disk sizes. Example builds range from about 72.5 GB (1-bit) up to about 354 GB (BF16). (huggingface.co)

Some tools may require a very recent GGUF runtime build for the qwen4exp architecture used by this model family. (huggingface.co)

Low-quality inputs can hurt results. Scanned text, messy copy-pastes, or inconsistent formatting can cause missed details and unstable structure.

Safety & compliance

This model is released under the Qwen Community License 1.0. You must keep the license notice with copies and follow applicable laws. (huggingface.co)

If you run a “Model as a Service” or “AI Work Assistant” business, you may need a separate license from Qwen for commercial use. (huggingface.co)

For very large commercial products (for example, extremely high monthly active users or very high monthly revenue), the license includes UI attribution requirements for the model name. (huggingface.co)

Model outputs can be wrong or incomplete, even when they look confident. Review claims before using them in real decisions.
