The day in brief

Cohere announced that its Series E has reached an initial close and is targeting up to C$7 billion, which would value it at C$35.7 billion ¹. It plans to use the funding for models, regulated-industry products and computing infrastructure ¹. Hugging Face’s guide describes Mistral Large 4 as taking text and images as input and generating text, while both documents give it a context window of up to 1 million tokens ².

OpenAI says its expanded monitors now cover frontier-model training, evaluations, internal use and selected external deployments ³. The system can flag suspicious behavior within minutes, but false alarms limit human review and some API traffic cannot be automatically stopped ³. PyTorch 2.15 makes CUDA 13.2 its default GPU build, with CUDA 13.4 wheels and experimental Rubin support also available ⁴.

Samsung expects tight memory supply to continue into 2028, according to executive vice president Jaejune Kim ⁷. Deepgram announced it is acquiring Daily and says Pipecat will remain free and vendor-neutral under an independent foundation ⁹. Serval announced a $150 million Series C led by Sequoia at a $3 billion valuation ¹⁰.
