OpenAI's GPT models are a family of state-of-the-art, general-purpose vision and language models that excel at natural language understanding, generation, reasoning, and multimodal processing. The variety of models includes high-intelligence chat models, reasoning models, lightweight and fast-inference mini models, and the o-series reasoning models that excel at complex, multi-step tasks.
In addition to language generation, OpenAI provides embedding models that generate high-dimensional vector representations of text. These embeddings are widely used in semantic search, recommendations, clustering, and RAG pipelines. They are fast, robust, and compatible with a variety of vector database systems, enabling performant retrieval-based AI workflows.
OpenAI also offers the Moderation API, a key tool for filtering harmful or sensitive content. It analyzes user-generated input and model output for categories such as hate speech, self-harm, sexual content, and violence—returning structured flags to help enforce content safety. This is especially important for production apps, as platforms like Apple require strong safeguards for generative content.
Further expanding their multimodal capabilities, OpenAI provides speech-to-text (STT) services via Whisper models, delivering highly accurate, multilingual transcription and translation from audio. Complementing this, OpenAI also supports text-to-speech (TTS) functionalities that generate natural, expressive speech from text for voice-enabled applications.
