Downloads: Hugging Face — ShayonSarker/SmolVLM-500M-Instruct-Q4_K_M-GGUF · Source &amp; build recipes: GitHub — model-SmolVLM-500M-Instruct-gguf · Base model: HuggingFaceTB/SmolVLM-500M-Instruct · Failed vision attempt: MM-GGUF

The GGUF binaries are hosted on Hugging Face; this repository holds the reproducible conversion pipeline, calibration data, and checksums.

Base: HuggingFaceTB/SmolVLM-500M-Instruct (Apache-2.0) · Quant: llama.cpp 0.4.1-dev · imatrix on 3000-line wikitext-2 (seed 42, 625 chunks, 4 threads)

⚠️ Scope correction: this repository holds the text tower only (291 tensors, llama arch — verified: image input is rejected). The SigLIP vision encoder and mmproj are NOT included, so this quant cannot see images. The PPL numbers below are valid for the text tower. The multimodal conversion attempt failed its 50-question ChartQA vision gate at 0/50 and is documented separately rather than shipped — see SmolVLM-500M-Instruct-MM-GGUF.

Format status

| File | Status | Note |

|---|---|---|

| smol-Q4_K_M.gguf | Published | Main release, ~303 MB |

| smol-Q8_0.gguf | Published | ~0.4 GB |

| F16 | Reference only | 0.8 GB source-side reference used for the PPL baseline; not published |

| mmproj (vision projector) | Not available | Vision conversion failed validation; see the MM repository |

Note: SmolVLM's 960-dim layers don't divide evenly for Q4_K, so llama.cpp fell back parts to q5_0/q8_0 (5.89 bits/weight). Valid imatrix quant, disclosed.

Eval (wikitext, 128 held-out lines, 2048 ctx)

| model | PPL | size |

|---|---|---|

| F16 | 13.5363 | 0.8 GB |

| Q8_0 | 13.5752 (+0.29%) | 0.4 GB |

| Q4_K_M | 13.7871 (+1.85%) | 0.3 GB |

Gate was <5% — passed, best of our three builds. Task evals not run: perplexity only, stated honestly. Files: smol-Q4_K_M.gguf, smol-Q8_0.gguf, imatrix.dat, calib.txt, REPRO.json, SHA256.txt.

Verified text outputs

Verbatim smol-Q4_K_M.gguf completions, --temp 0 -no-cnv, 24 new tokens, prompt form Question: ...\nAnswer:. SmolVLM is instruction-tuned, so it restates the answer several times before drifting into a new question; repeats are trimmed.

| Question | Model answer |

|---|---|

| What is the capital of Japan? | Tokyo |

| What is the capital of Italy? | The capital of Italy is Rome. |

| What is the capital of Egypt? | The capital of Egypt is Cairo. |

| What is the largest ocean on Earth? | Pacific Ocean |

| Which planet is closest to the Sun? | Mercury. |

| How many days are in a leap year? | 366 |

| How many continents are there? | 7 |

| What is the chemical symbol for gold? | Au (then adds Gold and The answer is: Gold) |

Answers are correct but extremely terse, and the same answer is repeated two to four times. This is the 500M text tower of a VLM: it is a small text baseline, not a vision model and not a chat assistant.

Use (text interface)

Ollama (see Modelfile):

ollama create smolvlm-500m-q4 -f Modelfile
ollama run smolvlm-500m-q4 "Summarize photosynthesis in 2 lines."

llama.cpp:

./llama-cli -m smol-Q4_K_M.gguf -p "Summarize photosynthesis in 2 lines." -c 2048

303MB: runs anywhere, fully offline. Do NOT pass images — no vision encoder in this file (see scope note).

Limitations

• Text tower only: no vision encoder, no mmproj, image input is rejected by the runtime.
• Perplexity-only validation; verify on your task before production use.
• English wikitext calibration: other languages/domains may vary.
• Repeats its answer up to four times; add a stop sequence or use the instruct template if that matters.
• Vision quality of the upstream VLM is untested here and should not be inferred from this repository.
