Multi-Agent

Most multi-agent AI systems are built by developers — frameworks assembled from components, with agents spawned programmatically, each given a role, each calling the others through APIs or queues. It’s architected software. What xAI shipped in mid-February is something structurally different: a model where the multi-agent council isn’t something you build around — it’s something that runs inside every response. Grok 4.20 Beta launched with four named agents — Grok, Harper, Benjamin, and Lucas — that execute a think-then-debate-then-consensus loop as part of the model’s native inference process. For queries below a complexity threshold, users may never notice the agents working. For hard problems, the loop is engaged automatically: agents independently reason about the problem, challenge each other’s conclusions, and surface a synthesized answer. You don’t configure this. It just runs. ...

For the past two years, multi-agent AI has been a developer story. You needed to understand orchestration frameworks, API keys, context windows, and process management to make multiple agents work together on a task. The Samsung Galaxy Unpacked event on February 25, 2026 marks the moment that story ends and a different one begins. Samsung confirmed ahead of the San Francisco event that Perplexity AI will be integrated into Galaxy AI for the S26 series — joining Bixby and Gemini as a natively accessible AI on the device. Perplexity gets its own wake phrase, and deep integrations with Samsung apps: Notes, Clock, Gallery, Reminder, Calendar. When a Galaxy S26 user asks a question, answers a message, or schedules an appointment, there are now three distinct AI systems that could be involved in handling that task, depending on what’s being asked and how. ...
