The first closed model (SemiAnalysis): According to SemiAnalysis, open-weight models have taken half as long to catch up to the first closed model in each successive LLM era: early scaling, reasoning, and agentic. The analysis compares release cadence across frontier models to assess whether the gap is narrowing.
