GPT-4 is a large language model developed by OpenAI and released in March 2023 as part of the Generative Pre-trained Transformer series. It accepts text input and produces text output, with a context window of 8,192 tokens, and its training data has a knowledge cutoff of April 2023. GPT-4 was designed to improve on earlier GPT models in areas such as instruction following, contextual understanding, and factual accuracy across a wide range of topics.

Whisper is a general-purpose speech recognition model developed by OpenAI and made available via the OpenAI API under the model ID whisper-1. It was trained on a large dataset of diverse audio, enabling it to handle a wide range of accents, background noise conditions, and technical vocabulary. What distinguishes Whisper is its multitask design: it can perform not only speech-to-text transcription but also speech translation into English and automatic language identification within a single model.

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.
