## Summary
Intel software engineers released LLM-Scaler-vLLM PV 1.5, a Docker-based stack designed for running Large Language Models on Intel Arc Graphics hardware. This update advances the stack closer to upstream by jumping from vLLM 0.14 to 0.26 and PyTorch 2.10 to 2.12. The release also introduces support for specific Qwen and Gemma models, along with new quantization capabilities.

## Technical improvements in PV 1.5
- Upgraded **vLLM** from 0.14 to 0.26 and **PyTorch** from 2.10 to 2.12.
- Added support for **Qwen3.6-27B**, **Qwen3.8-27B**, **Qwen3.6-35B-A3B**, **gemma-4-26B-A4B-it**, and **gemma-4-31B-it**.
- Introduced support for **online FP8** and **symmetric INT4** quantization.
- Added **FP8 KV cache** support.
- Improved performance for **time-to-first-token** (Qwen/Gemma 4), **MTP decoding**, **LoRA serving**, and **FP8 KV cache**.

## Why it matters
The update brings Intel Arc users closer to the upstream vLLM ecosystem and improves the efficiency of running LLMs on Intel consumer graphics hardware.
