MiniMax Releases MiniMax H3: An Omni-Modal Video Model That Generates 15-Second 2K Clips With Native Stereo Audio
MiniMax releases MiniMax H3, a general-purpose multimodal generation model. MiniMax H3 is not a text-to-video model with add-ons. MiniMax describes it as a general-purpose multimodal generation model that reads text, images, video, and audio as one unified context and returns video with native stereo sound. The mains specs include: 2K output, 4–15 seconds, integer durations only. Previous video stacks split into text-to-video, image-to-video, first-and-last-frame, subject reference, motion r
MiniMax H3 is a multimodal generation model that accepts text, images, video, and audio as input and produces video output with native stereo sound, generating clips up to 15 seconds at 2K resolution. Unlike previous systems that required separate specialized models for different tasks like text-to-video or image-to-video, H3 combines these capabilities into one unified model where relationships between inputs are expressed in natural language. The model is currently available through an API and consumer app, though open weights were promised but not yet shipped. H3 achieves native 2K output through a new tokenizer called H3-VAE that compresses information more efficiently, and it uses in-context regeneration to preserve fine details like small text and brand marks rather than relying on traditional upscaling methods.

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

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.
