ChatGate (formerly ChatGPT AI) vs A Generalist Agent

ChatGate at chatgpt.ai is a third-party AI gateway that routes chat, image, and video requests across ChatGPT, Gemini, Claude, and other major models from one web interface. You pick a model manually or leave routing on Auto, then generate without juggling separate provider accounts.

Unlike signing up directly with OpenAI or Google, ChatGate sells consolidated access through tiered subscriptions and adds a Discover feed that ranks newly launched AI apps by category. The chatgpt.ai domain redirects to chatgate.ai, so the product brands as ChatGate even though the listing URL predates the rename.

Builders, marketers, and researchers who want one bill for multiple frontier models fit here, especially if they also browse the Discover leaderboard for fresh tools. It is not the official OpenAI ChatGPT product at chat.openai.com.

Gato is the generalist agent DeepMind introduced in its May 2022 research post "A Generalist Agent." One transformer policy with shared weights handles chat, image captioning, Atari games, and real robot arm block stacking from the same model. The post describes it as a multi-modal, multi-task, multi-embodiment policy that picks whether to emit text, joint torques, button presses, or other tokens based on context.

Most tools in this space train a separate model per task domain. Gato instead serializes every modality and environment into a flat token sequence and runs it through a transformer shaped like a large language model. That means one pretrained checkpoint moves between dialogue, vision, and control without swapping architectures.

During training, data from simulated and real environments mixes with natural language and image datasets, with loss masked so Gato predicts only action and text targets. At deployment, a prompt tokenizes first, each new observation appends to the sequence, and the model samples an action vector one token at a time inside a 1024-token context window. The blog includes domain-grouped charts of tasks where the pretrained model clears expert score thresholds.
