Qwen3.8-Flash-Next-GGUF
Built from Qwen's original weights with our own importance matrix. The calibration corpora behind our builds are public. Qwen3.8-Flash-Next is the first open-weight release of the architecture behind Qwen4. These GGUFs are self-quantized from Qwen's original weights with our own importance matrix, published alongside the quants. The quants are still uploading and need a llama.cpp build with Qwen3.8-Flash-Next support...

Estimate: file size × 1.1 + KV cache at 8K + 0.5 GB overhead. Not a benchmark — how we calculate this.
