Frequently Asked Questions

How does "System Message" weight differ from "User Message" in GPT-4?

In GPT-4, the system message is not just a preamble; it is mathematically prioritized in the attention mechanism to provide a "steerability" baseline. For developers, this means core constraints (e.g., "Always output valid JSON") should live in the system message, while dynamic data should stay in the user message to prevent the model from "forgetting" its persona during long interactions.

Can GPT-4 handle parallel function calling, and how does it manage state?

Yes, GPT-4 can trigger multiple function calls in a single turn. From a developer’s perspective, these are returned as an array of tool calls. You must execute these calls in your backend and return the results as a sequence of "tool" role messages. The model remains stateless; you are responsible for maintaining the execution order and feeding the results back to get a final natural language response.

Is "Fine-tuning" GPT-4 always better than "Few-Shot" prompting?

Not necessarily. Fine-tuning is a heavy investment used to teach the model a new style or domain-specific vocabulary. For most logic-based tasks, "Few-Shot" prompting (providing 3-5 examples in the context) is more agile and allows you to update logic instantly without the cost and latency of maintaining a custom-weighted model.
