Capabilities, design details, and architectural traits
GPT-4 Turbo - A 128K-Context With Fresher Knowledge
GPT 4 Turbo is documented as the next generation of GPT 4, built around a much larger context window and more current knowledge of world events. OpenAI introduced it as more capable while also extending what a single prompt can hold.
| Trait | Detail |
|---|---|
| 128K context window | Fits the equivalent of more than 300 pages of text in a single prompt, a major jump from GPT 4's earlier 8k and 32k context limits. |
| Extended knowledge cutoff | Knowledge of world events updated to a more recent cutoff, with OpenAI stating it intended to keep this cutoff current going forward. |
| Structured output control | Introduced JSON mode, parallel function calling across multiple functions in one turn, and reproducible outputs through a seed parameter. |
| Vision integration | Released alongside GPT 4 Turbo with vision, extending the model to accept image input through the API. |
Launched Alongside the Assistants API
OpenAI introduced GPT 4 Turbo at the same event as its first Assistants API, described as the company's first step toward helping developers build agent-like experiences that have goals and can call models and tools.
