The Differences Between GPT-3 and GPT-4

The Differences Between GPT-3 and GPT-4

GPT-4 represents a significant leap over GPT-3 in reasoning, accuracy, and multimodal capability. Understanding these differences helps teams make informed decisions about which model fits their use case.

Key Differences

  • Context window: GPT-4 supports up to 128K tokens vs GPT-3's 4K
  • Reasoning: GPT-4 dramatically outperforms on complex multi-step tasks
  • Multimodal: GPT-4 can process images alongside text
  • Accuracy: GPT-4 hallucinates significantly less

    • Which Should You Use?

    For most production applications, GPT-4 is worth the cost premium. GPT-3.5 remains viable for simpler classification and summarization tasks.
