AI Models Specializations and Moving to Parallel and Many Agent Systems
by Brian Wang from NextBigFuture.com on (#73MXX)
xAI Grok 4.20 has native 4-agent council (Grok = Coordinator/Synthesizer, Harper = Research/Facts/X-grounding, Benjamin = Logic/Math/Code, Lucas = Creative/Balance). They run in parallel on shared weights + KV cache. Internal structured debate rounds + RL-optimized orchestration. It has large gains in reasoning depth, fact-checking, blind-spot detection, and open-ended engineering without exploding costs (effective ~1.5-2.5* single-pass ...
