The Q4_K_M export keeps token embeddings and the output matrix in F16, byte-identical to the F16 export. Transformer weights use mixed 4-bit quantization. This preserves the trained token rows and makes the file larger than a standard Q4_K_M export.

Both text exports passed actual GPU generation and OpenAI-style tool API tests, including a follow-up answer after a simulated tool result. All 240 Czech Lux benchmark prompts passed tokenization parity checks. These focused checks are separate from the merged BF16 Lux score of 72.92%; a GGUF Lux accuracy score is not claimed.

Natural GGUF tool probes: F16: 8/8, Q4_K_M: 8/8. Raw generation and the chat API agreed on tool presence. The API checks separately establish parsing and a successful call/result roundtrip; they do not guarantee that the model will choose a tool whenever requested.

Standalone thinking used the same four prompts and 2,048-token output limit as the merged BF16 probe. Completion requires native opening/closing tokens and EOS.

Use the embedded native chat template and a runtime with mistral3 and native V13 tool support. Actual thinking tokens are [THINK] / [/THINK] (34/35), and tool syntax is [TOOL_CALLS]function_name[ARGS]{"argument":"value"} (9/32). Start with an 8,192-token context. Reasoning is not guaranteed on every prompt, and long output can be truncated by the client. Vision quality was not tested.

The tested server runtime was llama.cpp b10830 (commit 465e49b9cea78a68b9c244ffb48d0ee24a82873d). A corresponding launch command is:

llama-server -m LuxAI-1-Nemo-Q4_K_M.gguf -ngl 99 -c 8192 --jinja --reasoning-format none

With this tested setting, thinking delimiters remain in the API message content; the client separates [THINK]...[/THINK] for display. Native function calls are returned as tool_calls. Do not assume every client recognizes the reasoning format automatically. The hosted ZeroGPU chat includes its own reasoning panel.

Exact source revision, separate converter/runtime versions, hashes, and test receipts are in GGUF_MANIFEST.json. Component notices and data attribution are preserved in the accompanying files.
