Dual Inference
Dual inference generates both a sequential text response and a structured prediction with confidence from a single model pass.
Dual inference is a way for AI models to give you two kinds of answers at once. When you ask a question, the AI can provide a regular text answer, like a sentence or paragraph. At the same time, it can also give you a structured prediction, which is like a specific data point or a classification, along with a score showing how confident it is about that prediction.
For example, imagine you ask an AI to describe an image. With dual inference, it could give you a written description of the image and also output a structured prediction like "This image contains a cat" with a confidence score of 0.95.
Dual inference enables a single forward pass of a model to produce both an autoregressive (sequential) output and a structured prediction, often accompanied by a confidence estimate. This approach aims to improve efficiency and potentially accuracy by leveraging shared representations for different output modalities within a unified model architecture.
This contrasts with traditional methods that might require separate models or distinct inference stages for text generation and structured prediction tasks. The tradeoff often involves model complexity and the specific design choices made to balance the generation of diverse output types.
Dual inference is gaining attention as frontier AI labs explore more efficient ways to extract rich information from models. This technique allows for simultaneous generation of both free-form text and precise, structured outputs, which is valuable for complex tasks like medical image analysis where both description and classification are needed.

The concept of dual inference, where a single model pass yields both sequential and structured outputs, has emerged from research into more versatile and efficient AI architectures. Specific implementations and naming may vary across research papers and labs.
Ask a chatbot like Copilot or ChatGPT to describe an image and also identify the main objects in it. See if it provides both a written description and a list of objects with confidence levels. You can also try asking for a summary of a document and simultaneously ask for a list of key dates mentioned.

Questions people ask
- Is dual inference faster than separate predictions?
- Potentially, yes. By performing both types of inference in a single pass, it can be more efficient than running two separate models or two distinct inference steps.
- Does dual inference always provide a confidence score?
- Often, yes. The structured prediction part of dual inference frequently includes a confidence score to indicate the model's certainty about that specific output.
