Sakana Chat Moves to Fugu Max and Adds Cross-Conversation Memory

Sakana AI updated Sakana Chat, its free browser-based playground for the Tokyo lab’s models, on September 17, 2026. The update brings the Fugu Max orchestrator into the chat interface and adds a memory feature that carries context across conversations.

Details

• Model refresh: Sakana Chat now runs on Fugu Max, the orchestrator model Sakana released on September 11 that routes each prompt to whichever model in its pool — including open-weight and Nemotron-family models — is best suited to it, aiming for frontier-comparable quality without relying on one large proprietary model
• Memory feature: what a user states once — their role, the project they’re working on, how they like answers formatted and written — carries over into later conversations instead of needing to be repeated each time
• User control: stored memories are reviewable in settings and can be disabled entirely
• Scope limits: only conversations started after the update contribute new memories; earlier chat history is not retroactively used, and the change does not extend to the API, where integrations must continue to manage their own conversation state

What happened next

The update is live immediately at chat.sakana.ai with no configuration needed. It arrives one day after a related update to Sakana’s Marlin research platform, rounding out a week in which Sakana pushed its new Fugu Max orchestrator into both its consumer chat product and its research tooling.
