GPT-4.5
GPT-4.5 is a text generation model from OpenAI with a 128,000-token context window and up to 8,000 tokens of output.
Large-context text generation from OpenAI
GPT-4.5 is a large language model developed by OpenAI, released under the full name gpt-4.5-preview. It was built by scaling both unsupervised pre-training and post-training processes, which OpenAI describes as improving the model's ability to recognize patterns, draw connections, and generate creative insights without relying on explicit reasoning steps. The model supports a 128,000-token context window and produces responses of up to 8,000 tokens.
GPT-4.5 is suited for tasks that benefit from a large context window, such as processing long documents, extended conversations, and complex text generation. Its current status in the MindStudio catalog is deprecated, meaning it is no longer actively maintained or recommended for new projects. Developers looking to use it should be aware that it was available as a preview and that OpenAI has since released subsequent models.
What GPT-4.5 supports
Large Context Window
Processes up to 128,000 tokens of input in a single request, enabling long documents and extended multi-turn conversations to fit within one context.
Text Generation
Generates natural language text across a wide range of formats and tasks, with a maximum response size of 8,000 tokens per completion.
Pattern Recognition
Identifies connections and patterns across large bodies of text through scaled unsupervised learning, without relying on explicit chain-of-thought reasoning.
Creative Synthesis
Generates creative insights and novel combinations of ideas by drawing on broad pattern recognition developed during pre-training.
