Qwen2.5-Coder-14B-Instruct — NVFP4

4-bit (NVFP4) quantization of Qwen/Qwen2.5-Coder-14B-Instruct, produced with NVIDIA TensorRT Model Optimizer and packaged for fast inference on the NVIDIA Jetson AGX Thor (Blackwell, compute capability sm_110a).

Built with anima-thor-ui — RobotFlow Labs' open control plane + latest-vLLM image for the Jetson Thor.

✨ Why this build

• ~3.5× smaller than the bf16 source — fits comfortably in the Thor's 128 GB unified memory with room for a large KV cache.
• Memory-bandwidth-optimal decode — NVFP4 moves ~0.55 bytes/param, roughly halving the bytes read per token versus fp8, which is what sets decode speed on bandwidth-bound edge GPUs.
• Drop-in OpenAI / Anthropic serving via the anima-vllm:thor-latest engine (vLLM 0.23 · PyTorch 2.11 · CUDA 13), or any vLLM build with NVFP4 (compressed-tensors) support.

🚀 Usage (vLLM)

vllm serve ilessio-aiflowlab/Qwen2.5-Coder-14B-Instruct-NVFP4-anima \
  --trust-remote-code --attention-backend TRITON_ATTN \
  --gpu-memory-utilization 0.70 --kv-cache-dtype fp8 --max-model-len 32768

from openai import OpenAI
client = OpenAI(base_url="http://localhost:8000/v1", api_key="x")
r = client.chat.completions.create(
    model="ilessio-aiflowlab/Qwen2.5-Coder-14B-Instruct-NVFP4-anima",
    messages=[{"role": "user", "content": "Write a Python function to check if a string is a palindrome."}],
)
print(r.choices[0].message.content)

On a Jetson use --runtime nvidia (not --gpus all). The first request JIT-compiles attention (~30–60 s), then it's cached.

🔬 Quantization details

🎯 Intended use & limitations

General-purpose inference on NVFP4-capable hardware (Blackwell and newer). Quality closely tracks the base model; as with any 4-bit PTQ, expect small deviations on the most numerically sensitive tasks. Inherits the base model's license, capabilities, biases, and intended-use terms — review the base model card. This is an independent community quantization, not affiliated with or endorsed by the base-model authors or NVIDIA.
