nxp/Qwen2.5-7B-Instruct-Ara240

Overview

This repository hosts the instruction‑tuned Qwen2.5-7B-Instruct model. Compared to earlier versions, Qwen2.5 offers stronger performance in areas such as coding, mathematics, long‑form generation, structured data handling, and JSON‑based outputs. It also responds more reliably to a wide range of system prompts, useful for scenarios like role‑playing agents or chatbot configuration. This specific repository provides the 7.61B‑parameter instruction‑tuned model quantized and compiled for Ara240 DNPU acceleration.

Model Description

This is a quantized and compiled version of Qwen/Qwen2.5-7B-Instruct optimized for Ara240 DNPU.

• Base Model: Qwen/Qwen2.5-7B-Instruct
• Original Model Authors: Qwen Team, Alibaba Cloud
• Original License: Apache-2.0
• Modified by: NXP

Performance

• SpecD - Uses a small draft model to generate speculated tokens, which the main model then verifies.
• Unpack - A smaller model with 4-bit layers for prompt processing; these layers are unpacked to 8-bit precision at runtime.
• TTFT: - Time to first token (TTFT). Reported as a range: the lower bound corresponds to prompts up to 128 tokens, and the upper bound reflects prompts at maximum context length.
• Avg. Token Rate: Averge token rate over the context length.

Model	Runtime	Context Length	SpecD	Unpack	Params (billion)	Time To First Token (s)	Avg. Token rate (Tokens/second)	DDR Memory (GB)
Qwen2.5-7B-Instruct	r2.0.4	4096	false	true	7.61	1.90 - 57.11	6.51	8.106

Modifications

This model is a derivative work with the following changes from the original:

• Quantization: W4A8 - QuaRot (wikitext-2-raw-v1) + EQAT (timdettmers/openassistant-guanaco)
• Compilation: Compiled for Ara240 DNPU
• Format: Converted to DVM format for NPU deployment

Original model available at: Qwen/Qwen2.5-7B-Instruct.

Limitations and Biases

This model inherits all limitations from the original Qwen2.5-7B-Instruct model. Additional limitations:

• Hardware-specific: Only runs on Ara240 DNPU
• Quantization effects: May have accuracy differences due to quantization

License

This model is released under the Apache License 2.0, the same license as the original Qwen/Qwen2.5-7B-Instruct model.
