Google opened Gemini 4 Argon to developers and businesses worldwide on October 13, at a launch price of $2 per million input tokens. That rate is set to double on December 1, raising costs for teams building on the model.
Liquid AI's d1-ultra takes text and images and returns calibrated probabilities in a single forward pass. It scores 65 on Artificial Analysis's Decision Index and is priced at $0.042 per million input tokens.
CERN and Mistral AI want to teach an AI model to read particle collisions from the Large Hadron Collider. Billed as a world first, the project could change how physicists explore the subatomic world.
AWS has released two open-source projects for building agents: Strands Decider 2B, a small model that makes decisions inside agent workflows, and Strands Box, a sandbox for controlling how agents execute. Together they target agents that call tools, run code and interact with outside systems.
Hugging Face is hosting Beam, an open model with 501 billion parameters. The release is pitched as a model that users can own, adapt to their needs and run at scale.
Vercel has added Reflection AI's Beam, the model previously tested under the stealth name Cat Jam, to its AI Gateway, free for a limited launch period. Beam is a US open-weight reasoning model under Apache 2.0, aimed at coding and agent work, with a 1M-token context and only 23B of its 501B parameters active per token.
