Training and Finetuning Reranker Models with Sentence Transformers
This tutorial covers training and fine-tuning reranker models with Sentence Transformers: datasets, loss functions, training arguments, evaluators, and trainer. It shows that small fine-tuned models like 'tomaarsen/reranker-ModernBERT-base-gooaq-bce' outperform popular public reranker models, and larger versions beat all general-purpose ones on the author's data.

AMD Introduces Threadripper Halo Station at IFA 2026
At IFA 2026, AMD unveiled the Threadripper Halo Station, a workstation combining a 96-core Zen 5 CPU with up to 4 Instinct MI350P cards (each 144GB HBM3E, 600W TBP). The system can hold a trillion-parameter model entirely on-device. Both CPU and GPUs are liquid-cooled. Full specs, pricing, and availability have not been announced.
AMD unveils Threadripper Halo Station, an AI workstation packing 96 cores and dual liquid-cooled MI350P accelerators — 'the most powerful workstation in the world' can run trillion-parameter models, says AMD
AMD unveiled the Threadripper Halo Station, an AI workstation it calls 'the most powerful in the world,' at IFA 2026. The system combines a 96-core Zen 5 Threadripper Pro 9995WX CPU with dual liquid-cooled Instinct MI350P accelerators (144GB HBM3E each), 2TB DDR5, and support for up to four GPUs. AMD claims it can run trillion-parameter models. Estimated component cost exceeds $100,000, with fully configured systems potentially over $150,000. No price or release date was announced, and AMD has not yet named OEM partners.
