  1. NVIDIA Releases France and Belgium Nemotron-Personas Datasets

    NVIDIA released the open Nemotron-Personas-France and Nemotron-Personas-Belgium locale-grounded persona datasets, created with Pleias and KU Leuven. The datasets belong to an open Nemotron data program covering 12 countries and can support post-training of open models for application-specific local knowledge, cultural nuance and regional languages. NVIDIA's accompanying tutorial covers generating synthetic conversations, fine-tuning with LoRA, merging the adapter and evaluating the resulting model.

  2. NVIDIA details Shopify's Nemotron 3.5 Lightning post-training for Sidekick

    NVIDIA published a blog post describing European retailers using open models and physical AI across commerce and fulfillment, led by Shopify's work on its Sidekick merchant assistant. According to the post, Shopify post-trained NVIDIA Nemotron 3.5 Lightning for a GraphQL subagent inside Sidekick, using the NVIDIA Megatron Bridge library for fine-tuning and NVIDIA NeMo RL for reinforcement learning, with the subagent retrieving store data for features such as Sidekick Pulse. NVIDIA says that on Shopify's internal benchmark the post-trained model surpassed a leading frontier model in accuracy while cutting serving costs by 90% and responding 7x faster, and that NVIDIA CCluster vLLM optimization delivered 4.5x faster performance and up to 12x lower inference cost across five other use cases. The post also cites Zooplus rebuilding product discovery with the Nemotron Retriever library to reach 86% search accuracy in a prototype, plus Photoroom, Omi with L'Oréal, Otto Group and Mirakl deployments.

  3. CoreWeave launches Forge to close the AI improvement loop

    At its Fully Connected event, CoreWeave announced CoreWeave Forge, a platform that links deployment, observability, curation, improvement and evaluation into a repeating loop so each production run (ideally) yields a better model and agent. It includes Agent Lens for inspecting agent behaviour and a Registry for checkpoints and agent configurations, plus RL Rollouts — currently in preview — and AI Object Storage, which now supports cross-region writes. CoreWeave says the loop stays open to different models, frameworks and clouds, and launched a partner network that adds You.com as a web-search layer for agents. According to the executives interviewed, CoreWeave worked with Nvidia and You.com to post-train Nemotron 3.5 Lightning in eight hours using RL Rollouts.
