Qwen3-4B-Instruct-2507-heretic OpenVINO INT4 for Intel NPU

This repository contains a ready-to-run OpenVINO IR export of p-e-w/Qwen3-4B-Instruct-2507-heretic, prepared for local inference on Intel NPU through OpenVINO Model Server.

This is not a fine-tune. It is an OpenVINO INT4 runtime export of the source model above.

Tested Intel NPU runtime

Tested locally on Windows with OpenVINO Model Server / OpenVINO GenAI:

• Target device: NPU
• OVMS task: text_generation

• Max concurrent sequences: 1
• Cache interval multiplier: 64

Example OVMS command:

ovms.exe `
  --model_path Q:/llm/models/OpenVINO/p-e-w--Qwen3-4B-Instruct-2507-heretic-text-fp16-true-int4-sym-cw-ov `
  --model_name p-e-w--Qwen3-4B-Instruct-2507-heretic-int4-npu `
  --rest_port 8000 `
  --rest_bind_address 0.0.0.0 `
  --task text_generation `
  --target_device NPU `
  --max_prompt_len 16384 `
  --max_num_seqs 1 `
  --cache_interval_multiplier 64 `
  --tool_parser hermes3

Local benchmark

Measured on the local Intel NPU setup above with the OVMS OpenAI-compatible chat completions endpoint.

Quantization	Load time	Avg output speed	Working set after runs	Private memory after runs
INT4_SYM	532.8 s	11.67 tok/s	7.42 GiB	2.57 GiB

The benchmark prompt was a short three-sentence OpenVINO explanation request with max_tokens=128.
