This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology. OpenAI has trained its LLM to confess to bad behavior What’s new: OpenAI is testing a new way to expose the complicated processes at work inside...

Amazon Nova 2 : quatre LLM multimodaux pour rattraper Google Cloud

Lors de re:Invent 2025 à Las Vegas, AWS a présenté Amazon Nova 2, la deuxième itération de sa collection de grands modèles de langage, la troisième en deux ans. S’il ne cherche plus à casser les prix, le fournisseur tient à convaincre ses clients d’adopter des modèles légèrement en deçà de leurs...

Quelles alternatives à CUDA pour le HPC et la programmation GPU ?

CUDA est devenu la référence dans le calcul intensif, l'optimisation LLM, machine learning, le compute vision, etc. CUDA est natif aux GPU NVIDIA et le constructeur fut évolué le langage, les API et les SDK. Mais CUDA reste fortement lié aux GPU NVIDIA. OpenMP pourrait être une alternative ouverte...

Powering HPC with next-generation CPUs

Powering HPC with next-generation CPUs

For all the excitement around GPUs—the workhorses of today’s AI revolution—the central processing unit (CPU) remains the backbone of high-performance computing (HPC). CPUs still handle 80% to 90% of HPC workloads globally, powering everything from climate modeling to semiconductor design. Far from...
