TimesFM-3: A zero-shot foundation model for multivariate forecasting
Data Management
A new time series forecasting model has been introduced that can predict multiple related data sequences simultaneously in a single computation step, rather than generating predictions one sequence at a time. Previously, similar models could only forecast based on the history of individual data sequences in isolation, but this model incorporates related sequences and known future information like scheduled events or promotions to improve forecast accuracy. The model was trained on over a trillion time points and uses a transformer architecture with alternating attention mechanisms that capture both temporal patterns within sequences and relationships across different sequences. This matters because real-world forecasting problems typically involve multiple interconnected data sequences and external factors, so a model that accounts for these dependencies can produce more accurate predictions without requiring customization for specific tasks.

Runway’s Praxis-1 world action model for robotics is now available
Praxis-1 builds on Runway’s work as a founding member of the Cosmos Coalition, advancing open world models for physical AI. | Source: Runway Runway AI Inc. yesterday released Praxis-1, its world action model for robotics. The model is now available to developers with open weights under the Apache 2.0 license. Runway first announced Praxis-1 in September with launch partners including Noble Machines, Standard Bots, and Ultra. Since then, these companies have been running the model on their own ha
Google releases Gemini 4 Carbon with agent ‘swarm’ feature
Google is rolling out its latest AI model, Gemini 4 Carbon, to the general public after releasing it to a select group of "cybersecurity defenders" two weeks ago. Google claims Carbon is its "strongest model" yet, and capable of competing with the very best systems from Anthropic and OpenAI. Google says Gemini 4 Carbon "pushes the frontier even further" than Argon, referring to the company's other frontier model that launched only last month. The company said Argon will likely
Gemini 4 Carbon is now available
The latest version aims to deliver improved performance while reducing the computational resources and energy required for AI operations.
Google Launches Gemini Decisions API With Gemini Decision 1 at $0.10/M Tokens
Google has launched the Gemini Decisions API, powered by a new model, Gemini Decision 1 (gemini-decision-1). The Gemini Decisions API does not generate text. It scores up to 1,000 typed questions against one shared input and returns calibrated probabilities. For developers, this targets the small branching calls inside agents: routing, policy checks, tool selection and grading. Google prices it at $0.10 per 1M input tokens, with zero output tokens billed. TL;DR Size: Context is 262,144 t
