We introduce PaperBench, a benchmark evaluating the ability of AI agents to replicate state-of-the-art AI research.
OpenAI の長年の信念は、画像生成を当社言語モデルの第一の能力とするべきだということです。それが、GPT‑4o に現時点で最も高度な画像ジェネレーターを統合した理由です。その成果として、画像生成は美しいものを生み出すだけではなく、有用なものとなりました。
4o image generation is a new, significantly more capable image generation approach than our earlier DALL·E 3 series of models. It can create photorealistic output. It can take images as inputs and transform them.
