GPT-3.5 Turbo 16k

GPT-3.5 Turbo with a 16,385-token context window, an expanded version of OpenAI's lightweight language model.

Strengths

Handles longer document processing and multi-turn conversations within a single request compared to the base 4K-window variant.

Best for

Chat and code generation tasks that require context beyond 4,000 tokens but don't need the reasoning or multimodal capabilities of newer GPT-4o models.

Limitations

Predated by the GPT-4o family and later o3 Mini High; lacks multimodal support and advanced reasoning; has a smaller context window than current OpenAI models.
