What is GPT?

GPT is OpenAI's large language model available through ChatGPT, the API, and Codex. Version 5.4 focuses on practical reliability for working developers and teams rather than just benchmark improvements. The main change is reduced retry rates, meaning the model produces acceptable output on the first attempt more often. This matters in real workflows where multiple attempts waste time and increase costs. GPT works across conversational interfaces, code generation, and programmatic API access, making it useful whether you're writing prompts in a chat interface or integrating it into applications.

Conversation history

maintain context across multiple exchanges in ChatGPT

Fine-tuning capability

customise the model on your own data through the API

Pros & cons

Advantages

  • More reliable outputs reduce time spent on retries and regenerating responses
  • Available across multiple interfaces, from simple chat to deep API integration
  • Free tier available for testing and lighter use
  • Works with code, text, analysis, and creative tasks in a single tool

Limitations

  • Free tier has usage limits and may have slower response times
  • Requires understanding of prompting to get consistent, useful results
  • API costs can accumulate quickly for high-volume applications
