Deep Learning Weekly Issue 454 covers developments in robotics foundation models, large language models, AI chips, and AI agents. Key concrete details include MolmoAct 2 running 37x faster than its predecessor, GPT-5.5 Instant reducing hallucinations by 52.5%, Blitzy raising $200M at $1.4B valuation, and OpenSeeker-v2 achieving 46.0% on BrowseComp benchmark with only 10.6k training data points. These advances enable faster robotics deployment, more reliable AI interactions, scaled coding automation, and accessible frontier search agent capabilities.

Ai2 launched the NSF-funded Open Multimodal AI Infrastructure for Science with NVIDIA Blackwell Ultra systems, providing compute infrastructure for open-source AI research accessible to the broader scientific community. The $152 million investment was awarded last year and the systems are now operational, with Ai2 estimating that 82% of typical training work is exploratory and can be reused across applications when shared openly. The infrastructure enables research outputs including Molmo 2 multimodal models, MolmoPoint with improved spatial reasoning, and Olmo Hybrid language models that other teams can inspect and build upon, creating multiplicative research value compared to closed proprietary systems.
