AT&T said it is routing more internal AI work to open models rather than sending all tasks to expensive systems. The company reported that open-model coding cut costs by 56% while accepting about a 2% quality tradeoff. As a result, teams will need stronger measurement to decide which tasks the router can safely keep on cheaper models.

Glenn Matlin and Chandreyi Chakraborty traced where an Olmo 3 language model’s social reasoning comes from by estimating how different training-document categories influenced benchmark answers. They sampled about 5.68 million documents from Dolma 3 (which contains about 1.26 billion documents) and found SocialIQA relied much more on narrative, interpersonal writing categories than other benchmarks. When they deleted the most influential literature data, the model’s SocialIQA score fell more than after removing random documents, suggesting training-data changes can measurably affect social reasoning ability.

Local deployment took the spotlight today, with NVIDIA making small enough models feel practical again. Its Nemotron 3.5 Bolt E4B targets a 4GB VRAM sweet spot for on-device voice agents, game NPCs, and robot interfaces, packing 8B parameters on paper (4B effective) and a 64K context window. The twist isn’t just the size; it’s the packaging. NVIDIA is offering an open-weight 4GB-environment build in Q4_K_M, alongside API and integration paths aimed at tool-calling agent behavior—meaning developers can stitch together speech, actions, and domain tools without needing a data center’s worth of compute.
