Try OpenAI NowWhy Are There So Many OpenAI Models?
OpenAI releases multiple models because no single system is the best fit for every study task or type of job. Some OpenAI models are optimized for raw capability, while others are optimized for speed or multimodal inputs such as images or audio.
The flagship ChatGPT models handle complex reasoning and high-stakes tasks, while lightweight GPT models are better for fast, repetitive work at scale.
Legacy models, which are earlier versions of OpenAI's language models that have since been replaced by newer releases, are still useful when you need simpler responses or to support older workflows that were built around a specific version.
