I build and test these releases myself. Your coffee helps keep me going.
Thank you for supporting this work.

Release status

This model card is ready for the release package. Quantized files will be added only after conversion, GGUF loading, and text generation have passed validation. No GGUF artifact is published in this initial card revision.

The planned text-only ladder is:

Priority	Planned file	Status
1	DeepSeek-V4.1-Flash-Q1_0.gguf	pending conversion and validation
2	DeepSeek-V4.1-Flash-Q2_K.gguf	pending conversion and validation
3	DeepSeek-V4.1-Flash-Q3_K_M.gguf	pending conversion and validation
4	DeepSeek-V4.1-Flash-Q4_K_M.gguf	pending conversion and validation
5	DeepSeek-V4.1-Flash-Q5_K_M.gguf	pending conversion and validation

About DeepSeek-V4.1-Flash

DeepSeek-V4.1-Flash is a multimodal sparse Mixture-of-Experts model. The upstream card describes a 763B-parameter model with a 552B backbone, a 1M-token maximum context, and approximately 8B active parameters during prefill and 16B during decode. It uses a 40-layer causal encoder-decoder design, Engram n-gram lookup tables, hyper-connections, compressed sparse attention, and a vision encoder. See the official model card for the original architecture, reference implementation, and usage limits.

Upstream DeepSeek-V4.1-Flash agentic performance benchmark; this image and its scores are from the official model card, not from these GGUF files.

The first GGUF package targets text inference. Vision, multimodal projector, and speculative MTP components will not be claimed unless they are separately converted and validated with the actual runtime.

This is a quantization-only release. No training, fine-tuning, merging, or model capability modification other than GGUF conversion and quantization is performed here.

Fidelity measurements

This section will be added after a fixed hold-out comparison against a valid reference has completed. No fidelity percentages are claimed yet.

Quick start

Commands will be added here with the exact published filename after the first GGUF passes load and generate smoke tests.

Reproducibility and validation

The upstream checkpoint is deepseek-ai/DeepSeek-V4.1-Flash at revision dba1be0a40aa45a94ad051997016db3960a90277. Its index reports 48 safetensors shards and a total source size of 510,286,023,000 bytes. The checkpoint uses the official mixed FP8/FP4 representation declared by its quantization_config; it is not a BF16 GGUF input and no community GGUF is used as a quantization source.

Conversion and runtime support use the DeepSeek-V4.1 work in vcruz305/llama.cpp, commit 5210c7c5ed61dddaee6ed476623abf4b63093d16, with the V4.1 converter/runtime path documented in the local reproducibility manifest. Each published file will include a SHA-256 checksum and will be listed only after a real load and generation smoke test.

Raw conversion, imatrix, quantization, smoke-test, fidelity, and benchmark logs remain local under reports/ and are not uploaded to the Hub.
