GPT-3.5 Turbo Instruct
OpenAI · Released Sep 2023
GPT-3.5 Turbo Instruct is OpenAI's instruction-tuned variant of GPT-3.5 Turbo, designed for following explicit directives rather than conversational chat.
- Strengths
- It excels at single-turn instruction following and generates structured outputs when given clear task specifications without needing conversation-style prompting.
- Best for
- Workloads requiring direct command execution, form filling, and templated text generation where conversational context is not needed.
- Limitations
- With only a 4K token context window, it cannot handle long documents or extensive conversation histories; for larger contexts or chat-based interactions, GPT-3.5 Turbo 16k or later models are better suited.
