DeepSeek V4.1 Flash 552B (16B active)

User benchmarks XeMaya, a new Intel Arc inference engine forked from XeStrata, on DeepSeek V4.1 Flash, GLM 5.3 Flash and Qwen3.8 Flash-Next. The regular DeepSeek V4.1 Flash model runs at 11.4 t/s prefill and 14.56 t/s generation on a B70 32GB plus B65 32GB. Setup is XeMaya over SYCL and Level Zero on an Ubuntu server with a B70 32GB, B65 32GB, B60 24GB, Ryzen 9950X and 128GB RAM. GLM 5.3 Flash reaches 152-161 t/s prefill and 17.4 t/s generation, around 20 t/s with MTP; DeepSeek V4.1 Flash Coder reaches 224.8 / 21.7 t/s after optimization. Using all three GPUs is slower than two for the regular DeepSeek model (11.2 / 11.58 t/s) because the B60 sits on a slower chipset link. The user notes the comparisons are not perfectly controlled, with different model files, prompts and GPU configurations.
