GPT-3.5 Turbo

OpenAI's lightweight language model for chat and code tasks with a 16K token context window.

Strengths

Fast inference and efficient at common chat and code completion tasks, with a larger context window than the 4K version to handle longer conversations or documents.

Best for

General-purpose chat applications, customer support, and code generation where context beyond 4K tokens is useful but full model capabilities are not required.

Limitations

Smaller context window than GPT-4o and GPT-4 Turbo (128K), and superseded by GPT-4o-mini for most modern use cases where multimodal support or better performance is needed.
