PROFILE

Thomas Atta-fosu

Thomas Atta-Fosu contributed to the vllm-project/vllm-gaudi and mlcommons/inference repositories, focusing on backend development and deep learning model optimization using Python and Shell scripting. He delivered multimodal support for Qwen2.5-VL-7B by integrating image and video embeddings into the model’s forward pass and enhancing the HPU model runner for mixed-modality data. Thomas also fixed batching logic for multimodal encoders, addressed rotary positional embedding issues for Qwen3 MoE models, and stabilized CI workflows by isolating flaky tests. His work improved model reliability, expanded visual data processing capabilities, and ensured inference outputs aligned with reference constraints, demonstrating strong technical depth.
