Description

Gemini 3 Flash is a next-generation AI model created to deliver powerful intelligence without sacrificing speed. Built on the Gemini 3 foundation, it offers advanced reasoning and multimodal capabilities with significantly lower latency. The model adapts its thinking depth based on task complexity, optimizing both performance and efficiency. Gemini 3 Flash is engineered for agentic workflows, iterative development, and real-time applications. Developers benefit from faster inference and strong coding performance across benchmarks. Enterprises can deploy it at scale through Vertex AI and Gemini Enterprise. Consumers experience faster, smarter assistance across the Gemini app and Search. Gemini 3 Flash makes high-performance AI practical for everyday use.

Description

Step 3.5 Flash is a cutting-edge open-source foundational language model designed for advanced reasoning and agent-like capabilities, optimized for efficiency; it utilizes a sparse Mixture of Experts (MoE) architecture that activates only approximately 11 billion of its nearly 196 billion parameters per token, ensuring high-density intelligence and quick responsiveness. The model features a 3-way Multi-Token Prediction (MTP-3) mechanism that allows it to generate hundreds of tokens per second, facilitating complex multi-step reasoning and task execution while efficiently managing long contexts through a hybrid sliding window attention method that minimizes computational demands across extensive datasets or codebases. Its performance on reasoning, coding, and agentic tasks is formidable, often matching or surpassing that of much larger proprietary models, and it incorporates a scalable reinforcement learning system that enables continuous self-enhancement. Moreover, this innovative approach positions Step 3.5 Flash as a significant player in the field of AI language models, showcasing its potential to revolutionize various applications.
