Sam Altman reveals the benchmark that may matter more than model IQ: 54% better token efficiency on agentic coding "5.6 Sol, I think, is not only the best model in the world for most people." "It's also much more efficient than other models out in the world." "So it's 54% more token efficient on agentic coding tasks and also as good or better as the other best models out there." "And we're really seeing people now start to care about efficiency, understand their spend, get a great ROI." "So this is a great step forward for us." The model race is moving from leaderboard intelligence to cost per completed task. The same agentic work at radically lower token cost changes product margins, rate limits, and how much autonomy an enterprise can afford. The next moat may not be the smartest model. It may be the system that turns each dollar of inference into the most reliable work. - Sam Altman (@sama), CEO of OpenAI, on @CNBC
