OpenAI's Ted Sanders shares a rule of thumb for picking the right GPT-model

OpenAI's Ted Sanders categorized the new GPT-6.1 Terra and explained how the company names its language models, noting that performance is multidimensional and most gaps come down to model size, though newer smaller models can outperform older larger ones through better training data or architectures. He said GPT-6.1 Terra is likely better than the larger Astra at technical communication and roughly matches it in image processing and computer use at a much lower price, but falls short in most other areas. His rule of thumb: "If you care about quality only, pick Astra. If you're a bit price sensitive, pick Sol. If you're very price sensitive, pick Terra or Luna."
