Description

Gemini 4 Krypton is an unreleased AI model reportedly under development at Google DeepMind, with early discussions positioning it as a potential addition to the Gemini 4 lineup. The model has attracted attention through unofficial demonstrations comparing its performance with Gemini 4 Argon and Gemini 4 Carbon. These demonstrations suggest that Krypton may be optimized for demanding programming assignments, advanced reasoning, and the creation of complex digital experiences. Reported examples include generating interactive web applications, detailed user interfaces, animated content, and substantial amounts of executable code. Some early testers claim that Krypton spends significantly more time processing requests and produces larger implementations than other Gemini models. This approach could make it particularly useful for software development projects that require extensive planning, iterative refinement, and multiple interconnected components. As a member of the Gemini family, Krypton may incorporate capabilities associated with Google's multimodal AI research and intelligent agent development. However, Google has not officially confirmed the model's architecture, supported input formats, benchmark performance, pricing, or public availability. If these reported capabilities are validated, Gemini 4 Krypton could become a powerful option for developers and organizations working on sophisticated AI-assisted programming and automation projects.

Description

Kimi K3 is a large-scale AI model from Moonshot AI designed for advanced reasoning, software engineering, visual understanding, agentic workflows, and knowledge work. The model is built with 2.8 trillion parameters and uses Kimi Delta Attention, a hybrid linear attention design created to support long-context intelligence. It also includes Attention Residuals and a native 1 million token context window, giving developers room to work with large files, repositories, documentation sets, transcripts, and enterprise knowledge bases. Kimi K3 always runs with thinking mode enabled and currently supports maximum reasoning effort by default. Developers can access the model through Moonshot’s OpenAI-compatible API using Python, cURL, and the OpenAI SDK. The API supports standard chat completions, streaming output, structured JSON Schema responses, partial continuation from a prefix, custom tool calling, required tool choice, and dynamic tool loading. Kimi K3 also supports vision inputs, including local images encoded as base64 and video files uploaded through the file API. Automatic context caching helps repeated long-prefix workflows become more efficient without requiring manual cache IDs or extra cache parameters. By combining long context, visual understanding, tool use, structured output, and advanced reasoning, Kimi K3 is built for developers creating sophisticated AI agents, coding systems, research tools, and enterprise applications.
