30B model post-trained on an operational graph beats a 550B generalist: specialization over scale
joecole · x · 2026-09-11
A thread argues a 30B model post-trained on a governed operational graph (objects, links, constraints, decisions, outcomes) beating a 550B generalist is expected: reasoning over structured business reality beats guessing over tables. The loop: discover the graph, bind the agent, capture accepted/edited decisions back, retrain. Open-source GraphJin (Apache 2.0) implements this with GraphQL+MCP and compiler-level policy, reporting 0 unsafe effects across 3,351 attempts on a public benchmark.
