Same model. Same benchmark. 6x performance gap. Only the harness changed. Stanford's Meta-Harness automates the code around the model. 7.7 points better, 4x fewer tokens. The model didn't get smarter. The system did. Are you still only optimizing prompts? Tell me what you're building #MetaHarness #ContextEngineering #AIEngineering #LLMs #TechTok
