FAQ

Common questions about OpenAI: GPT-4 Turbo Preview

Read the docs

It is a research preview of GPT-4 Turbo with 128K context window, JSON mode, and parallel function calling. Pricing is $10/M input and $30/M output tokens. Use model name gpt-4-turbo-preview.

It offers 16x larger context, faster inference, and reproducible outputs via seed. Better for code generation and text transformations. Some note occasional laziness in complex tasks.

Supports 128,000 input tokens but max 4,096 output tokens. Largest commercially available at release. Ideal for big documents.

Access via platforms like OpenRouter with OpenAI-compatible API. Matches features like improved instruction following. Snapshots ensure consistent behavior.

Includes JSON mode, parallel function calling, and vision preview variant. Knowledge cutoff April 2023. Rate limits apply per deployment.

Announced November 2023 as GPT-4-1106-preview. Older high-intelligence model now recommended to upgrade from. Use for stable, large-context tasks.
