How GPT-5.5 Works
GPT-5.5 is built on the transformer architecture. During training, it learns statistical patterns in language from large datasets. At inference time, it predicts the next most appropriate token based on the prompt and conversation context.
Typical workflow:
- User submits a prompt.
- The model interprets the request.
- It considers the conversation context.
- It generates a coherent response.
- Safety systems help reduce harmful or inappropriate outputs.
