OpenAI: GPT-4 32k (older v0314)

GPT-4-32k is an advanced iteration of GPT-4, offering identical core capabilities but with a significantly expanded context window—four times larger than its predecessor. This enhancement enables the model to process up to 40 pages of text in a single interaction, making it exceptionally well-suited for managing extensive documents, such as PDFs, without the need for external vector databases. Trained on data up to September 2021, GPT-4-32k combines cutting-edge performance with the ability to handle complex, long-form content seamlessly.
