+ | File | Quant | Size | Notes |
19
+ |---|---|---:|---|
20
+ | [Qwen3-0.6B-BF16.gguf](https://huggingface.co/NANI-Nithin/Qwen3-0.6B-GGUF/blob/main/Qwen3-0.6B-BF16.gguf) | `BF16` | 1.41 GB | Full precision source. Every quant below is cut from this file. |
21
+ | [Qwen3-0.6B-Q8_0.gguf](https://huggingface.co/NANI-Nithin/Qwen3-0.6B-GGUF/blob/main/Qwen3-0.6B-Q8_0.gguf) | `Q8_0` | 0.75 GB | Effectively lossless. Use when disk and RAM are not the constraint. |
22
+ | [Qwen3-0.6B-Q6_K.gguf](https://huggingface.co/NANI-Nithin/Qwen3-0.6B-GGUF/blob/main/Qwen3-0.6B-Q6_K.gguf) | `Q6_K` | 0.58 GB | Near-lossless; the last stop before quality becomes measurable. |
23
+ | [Qwen3-0.6B-Q5_K_M.gguf](https://huggingface.co/NANI-Nithin/Qwen3-0.6B-GGUF/blob/main/Qwen3-0.6B-Q5_K_M.gguf) | `Q5_K_M` | 0.51 GB | Very good quality, noticeably smaller than Q6_K. |
24
+ | [Qwen3-0.6B-Q5_K_S.gguf](https://huggingface.co/NANI-Nithin/Qwen3-0.6B-GGUF/blob/main/Qwen3-0.6B-Q5_K_S.gguf) | `Q5_K_S` | 0.51 GB | Slightly smaller than Q5_K_M for a slight quality cost. |
25
+ | [Qwen3-0.6B-Q5_1.gguf](https://huggingface.co/NANI-Nithin/Qwen3-0.6B-GGUF/blob/main/Qwen3-0.6B-Q5_1.gguf) | `Q5_1` | 0.54 GB | Legacy. Prefer Q5_K_M. |
26
+ | [Qwen3-0.6B-Q5_0.gguf](https://huggingface.co/NANI-Nithin/Qwen3-0.6B-GGUF/blob/main/Qwen3-0.6B-Q5_0.gguf) | `Q5_0` | 0.51 GB | Legacy. Prefer Q5_K_M. |
27
+ | [Qwen3-0.6B-Q4_K_M.gguf](https://huggingface.co/NANI-Nithin/Qwen3-0.6B-GGUF/blob/main/Qwen3-0.6B-Q4_K_M.gguf) | `Q4_K_M` | 0.45 GB | The usual default. Best quality-per-byte for most people. |
28
+ | [Qwen3-0.6B-Q4_K_S.gguf](https://huggingface.co/NANI-Nithin/Qwen3-0.6B-GGUF/blob/main/Qwen3-0.6B-Q4_K_S.gguf) | `Q4_K_S` | 0.44 GB | A little smaller than Q4_K_M, a little worse. |
29

30
+ | [Qwen3-0.6B-IQ4_XS.gguf](https://huggingface.co/NANI-Nithin/Qwen3-0.6B-GGUF/blob/main/Qwen3-0.6B-IQ4_XS.gguf) | `IQ4_XS` | 0.42 GB | Best sub-4.5bpw option; usually beats Q4_K_S at a smaller size. |
31
+ | [Qwen3-0.6B-Q4_1.gguf](https://huggingface.co/NANI-Nithin/Qwen3-0.6B-GGUF/blob/main/Qwen3-0.6B-Q4_1.gguf) | `Q4_1` | 0.47 GB | Legacy. Prefer Q4_K_M. |

33
+ | [Qwen3-0.6B-Q3_K_L.gguf](https://huggingface.co/NANI-Nithin/Qwen3-0.6B-GGUF/blob/main/Qwen3-0.6B-Q3_K_L.gguf) | `Q3_K_L` | 0.41 GB | Small, with real quality loss. Usable when RAM is tight. |
34
+ | [Qwen3-0.6B-Q3_K_M.gguf](https://huggingface.co/NANI-Nithin/Qwen3-0.6B-GGUF/blob/main/Qwen3-0.6B-Q3_K_M.gguf) | `Q3_K_M` | 0.39 GB | Smaller again; noticeable degradation. |
35
+ | [Qwen3-0.6B-IQ3_M.gguf](https://huggingface.co/NANI-Nithin/Qwen3-0.6B-GGUF/blob/main/Qwen3-0.6B-IQ3_M.gguf) | `IQ3_M` | 0.38 GB | Strong at ~3.7bpw, clearly better than Q3_K_M. |
36
+ | [Qwen3-0.6B-IQ3_S.gguf](https://huggingface.co/NANI-Nithin/Qwen3-0.6B-GGUF/blob/main/Qwen3-0.6B-IQ3_S.gguf) | `IQ3_S` | 0.36 GB | Slightly smaller than IQ3_M. |

38
+ | [Qwen3-0.6B-IQ3_XS.gguf](https://huggingface.co/NANI-Nithin/Qwen3-0.6B-GGUF/blob/main/Qwen3-0.6B-IQ3_XS.gguf) | `IQ3_XS` | 0.35 GB | Aggressive but coherent. |
39
+ | [Qwen3-0.6B-IQ3_XXS.gguf](https://huggingface.co/NANI-Nithin/Qwen3-0.6B-GGUF/blob/main/Qwen3-0.6B-IQ3_XXS.gguf) | `IQ3_XXS` | 0.32 GB | Very aggressive; imatrix carries it. |
40
+ | [Qwen3-0.6B-Q2_K.gguf](https://huggingface.co/NANI-Nithin/Qwen3-0.6B-GGUF/blob/main/Qwen3-0.6B-Q2_K.gguf) | `Q2_K` | 0.32 GB | Very small, heavily degraded. For experimentation. |
41
+ | [Qwen3-0.6B-IQ2_M.gguf](https://huggingface.co/NANI-Nithin/Qwen3-0.6B-GGUF/blob/main/Qwen3-0.6B-IQ2_M.gguf) | `IQ2_M` | 0.31 GB | The smallest size most people find usable. |
42
+ | [Qwen3-0.6B-Q2_K_S.gguf](https://huggingface.co/NANI-Nithin/Qwen3-0.6B-GGUF/blob/main/Qwen3-0.6B-Q2_K_S.gguf) | `Q2_K_S` | 0.31 GB | Smaller than Q2_K, requires the imatrix. |
43
+ | [Qwen3-0.6B-IQ2_S.gguf](https://huggingface.co/NANI-Nithin/Qwen3-0.6B-GGUF/blob/main/Qwen3-0.6B-IQ2_S.gguf) | `IQ2_S` | 0.30 GB | Below the usual usability line. |

51
+ ## Which one should I download?
52
+
53
+ Pick the largest file that leaves a couple of gigabytes of headroom on the device you will run it on — the model has to fit in RAM (or VRAM, if you are offloading) alongside the KV cache and the OS.
54
+
55
+ - Plenty of memory: **Q6_K** or **Q8_0**.
56
+ - The usual choice: **Q4_K_M**.
57
+ - Tight on memory: **IQ4_XS**, then **IQ3_M**, then **IQ2_M**.
58
+ - The `IQ*` files are imatrix-guided and generally beat a `Q*` file of similar size, at the cost of slightly slower inference on some hardware.
59
+
60
+ ## Quantization details
61
+
62
+ - Importance matrix computed with `llama-imatrix` over 500 rows of [Salesforce/wikitext](https://huggingface.co/datasets/Salesforce/wikitext) (`wikitext-2-raw-v1`).
63
+ - The matrix was computed on the **BF16** weights.
64
+ - K-quants below 6 bit and the whole `IQ` set are imatrix-guided. `Q4_0`/`Q4_1`/`Q5_0`/`Q5_1` are legacy round-to-nearest and ignore it; `Q6_K`/`Q8_0` are near-lossless and do not need it.
65
+ - All files are cut from the same BF16 GGUF, so differences between them are quantization only.

67
+ ## Usage
68
+
69
+ ```bash
70
+ llama-cli -hf NANI-Nithin/Qwen3-0.6B-GGUF:Q4_K_M -p "Hello"
71
+ ```
72
+
73
+ Or download one file and point at it directly:
74
+
75
+ ```bash
76
+ huggingface-cli download NANI-Nithin/Qwen3-0.6B-GGUF Qwen3-0.6B-Q4_K_M.gguf --local-dir .
77
+ llama-cli -m Qwen3-0.6B-Q4_K_M.gguf -p "Hello"
78
+ ```
