GPT-4o mini Transcribe is a speech-to-text model developed by OpenAI that uses the GPT-4o mini architecture to convert spoken audio into written text. It is designed to deliver improved word error rates and more accurate language recognition compared to the original Whisper-based transcription models. The model is part of OpenAI's transcription API offerings and became available in 2025.

GPT-4o Transcribe is a speech-to-text model developed by OpenAI that uses the GPT-4o model architecture to convert spoken audio into written text. It is part of OpenAI's audio model lineup and was introduced as an improvement over the original Whisper-based transcription models, offering a lower word error rate and more accurate language recognition across a broader range of languages.

GPT-4o-mini TTS is a text-to-speech model developed by OpenAI that converts written text into natural-sounding spoken audio. It belongs to the GPT-4o mini family, which is designed to deliver capable output at a smaller computational footprint than full-scale variants. The model is accessible to developers through the OpenAI API and is intended for programmatic speech generation across a range of applications. It accepts a text input of up to 2,000 characters and returns audio output in a synthesized voice.

Handles both text and image inputs for content generation and problem-solving.
