XAI Launches Grok 4.20 and it Has 4 AI Agents Collaborating
It is not one AI. It is four AI Agents.
xAI built a 4 Agents system – four specialized AI agents that think in parallel and debate each other in real-time before giving you an answer.
This isn't a single monolithic model but a multi-agent system where multiple replicas (or specifically four specialized agents named Grok, Harper, Benjamin, and Lucas) deliberate and debate in parallel before generating a response, aiming to produce more thoughtful, well-rounded outputs.
It has good but limited set of benchmarks so far. Great Safety Overfit tests, ranking #2 on ForecastBench, and delivering strong results in live trading competitions like Alpha Arena (with +34.59% returns where competitors posted losses).
