Qwen3-0.6B-YaRN-GGUF

These are YaRN extended versions of Qwen3-0.6B for use with:

• The new Qwen3-235B-A22B-Instruct-2507, Qwen3-235B-A22B-Thinking-2507 and Qwen3-Coder-480B-A35B-Instruct models that support up to 256k context length.
• (Potentially) any model via Universal Assisted Generation added to llama.cpp in #12635.

---

I've included the Q4_0 quants for 4 different context lengths:

• Qwen3-0.6B-32k-Q4_0.gguf
• Qwen3-0.6B-64k-Q4_0.gguf
• Qwen3-0.6B-128k-Q4_0.gguf
• Qwen3-0.6B-256k-Q4_0.gguf

NOTE: Because llama.cpp uses "static-YaRN" the scaling factor remains constant regardless of input length:

• Only use the YaRN-extended versions when processing long contexts is required.
• Use the smallest YaRN-extension possible.

How these were created

To extend the context to 64k:

1. Edit the config.json file:

  "max_position_embeddings": 65536,
  ...
  "rope_scaling": {
    "factor": 2.0,
    "original_max_position_embeddings": 32768,
    "type": "yarn"
  },

1. Convert and quantize:

./llama.cpp/convert_hf_to_gguf.py --outtype auto --outfile  Qwen3-0.6B-64k-BF16.gguf Qwen3-0.6B
./llama.cpp/build/bin/llama-quantize Qwen3-0.6B-64k-BF16.gguf Qwen3-0.6B-64k-Q4_0.gguf Q4_0 44

To extend the context to 128k:

1. Edit the config.json file:

  "max_position_embeddings": 131072,
  ...
  "rope_scaling": {
    "factor": 4.0,
    "original_max_position_embeddings": 32768,
    "type": "yarn"
  },

1. Convert and quantize:

./llama.cpp/convert_hf_to_gguf.py --outtype auto --outfile  Qwen3-0.6B-128k-BF16.gguf Qwen3-0.6B
./llama.cpp/build/bin/llama-quantize Qwen3-0.6B-128k-BF16.gguf Qwen3-0.6B-128k-Q4_0.gguf Q4_0 44

To extend the context to 256k:

1. Edit the config.json file:

  "max_position_embeddings": 262144,
  ...
  "rope_scaling": {
    "factor": 8.0,
    "original_max_position_embeddings": 32768,
    "type": "yarn"
  },

1. Convert and quantize:

./llama.cpp/convert_hf_to_gguf.py --outtype auto --outfile  Qwen3-0.6B-256k-BF16.gguf Qwen3-0.6B
./llama.cpp/build/bin/llama-quantize Qwen3-0.6B-256k-BF16.gguf Qwen3-0.6B-256k-Q4_0.gguf Q4_0 44

How to patch the GGUF files for other context lengths

1. First work out the new scale factor, eg: for 1M context (2^20 = 1048576) we need 1048576/32768 = 32.0.

2. Copy one of the existing YaRN-extended GGUF files (ie: NOT Qwen3-0.6B-32k-Q4_0.gguf!) and patch it using gguf_set_metadata.py:

./llama.cpp/gguf-py/gguf/scripts/gguf_set_metadata.py Qwen3-0.6B-1M-Q4_0.gguf qwen3.context_length 1048576
./llama.cpp/gguf-py/gguf/scripts/gguf_set_metadata.py Qwen3-0.6B-1M-Q4_0.gguf qwen3.rope.scaling.factor 32.0

1. Check the patch has worked using gguf_dump.py:

./llama.cpp/gguf-py/gguf/scripts/gguf_dump.py --no-tensors  Qwen3-0.6B-1M-Q4_0.gguf
