Google's Gemini 4 Carbon is now available on AI Gateway under the model name google/gemini-4-carbon, aimed at complex software engineering, sustained agentic work and cybersecurity defense, with a 1M-token context window for large codebases and long inputs. Google reports improvements in coding, full-stack web development and scientific reasoning on multi-stage engineering tasks, cybersecurity coverage from finding vulnerabilities through validating risk to developing patches, and more reliable multi-step plan execution, fewer unsupported claims and better collaboration when requirements are ambiguous. Calls through AI Gateway reflect provider pricing with no markup and no platform fee on inference, at 50% off through November 30, 2026.

Google's Gemini 4 Hydrogen is now available on AI Gateway, succeeding Gemini 3.8 Flash. It targets agentic coding, knowledge work and tool use, handling longer engineering tasks and producing better-researched documents, spreadsheets and presentations in fewer agent steps while staying in the same latency class. It follows system instructions, formatting requirements and task boundaries more closely, orchestrates tools more reliably across long conversations, and its gains in visual reasoning and technical problem-solving support multimodal workflows.

Anthropic's Claude Fable 5.2 is now callable through AI Gateway, built for open-ended technical work and improving on earlier Fable models in coding, reasoning and vision, and able to run long, ambiguous tasks unattended. It can act as an orchestrator that hands simpler tasks to smaller models, or as an advisor other Claude models consult on harder problems, with clearer communication and faster output. The model ships with cybersecurity and biology safety classifiers, and access requires data retention: prompts and completions are kept for 30 days and not used to train Claude, while teams with Zero Data Retention enabled get an error instead of a forwarded request.

Mistral has moved Mistral Large 4 on AI Gateway to updated weights and lowered the price of input, cached input and output tokens. According to Mistral's release announcement, the new weights improve agentic coding and defensive cybersecurity, use tokens more efficiently on coding tasks, and also improve spreadsheet creation and editing, web research, and resistance to prompt injection. Users already calling mistral/mistral-large-4 through AI Gateway need no model change to get the new weights and pricing.

Vercel Labs has released agent-desktop, which lets AI agents operate desktop apps on macOS, Windows and Linux without screenshots or pixel matching. It reads an app's accessibility tree as JSON, assigns a ref to every element the agent can act on, and the agent clicks or types on a ref, then reads the UI again to verify. The tool ships as a CLI and a C library, contains no model, and leaves the observe-act-verify loop in the agent.

Ampersand, a language model from Humans&, is now available free on AI Gateway through November 13, 2026. It is built for multi-person conversations such as team chats, deciding on each turn whether to speak or stay quiet, and is designed to understand individual and shared goals and help people work through disagreements. An application exposes speaking and silence as two caller-defined tools, send_message and pass, which the application executes and records; the model accepts auto and none tool choices but rejects required and named ones.
