OpenAI's Ted Sanders explains GPT-6.1 Terra naming and model performance factors

OpenAI's Ted Sanders categorizes the new GPT-6.1 Terra, stating that model performance depends on multiple dimensions including size, reasoning effort, and multi-agent systems. He notes that newer, smaller models can outperform larger ones through better training data or architecture. GPT-6.1 Terra is priced lower than Astra and performs similarly in image processing and computer use, but falls short in most other areas.
