Inference
Inference is the process of running a trained AI model on new input data to generate predictions, responses, or decisions, as opposed to training, which is the process of building the model from data.
Understanding Inference
The AI development lifecycle has two distinct phases: training and inference. Training is where a model learns by processing massive datasets and adjusting billions of parameters. Inference is where the trained model is deployed to process new inputs and generate outputs in real time. For users of AI applications, all interactions happen during inference. Inference performance is measured in latency (how fast a response is generated) and throughput (how many requests can be handled simultaneously). Both are critical for production AI systems. A slow model that takes 30 seconds to respond breaks the flow of productive work. Several techniques improve inference efficiency. Quantization reduces the precision of model weights, significantly reducing memory requirements and speeding up computation with minimal quality loss. Speculative decoding uses a smaller draft model to predict multiple tokens at once. GPU batching processes multiple requests simultaneously to improve throughput. Streaming inference sends tokens to the user as they are generated rather than waiting for the complete response. This dramatically improves perceived latency and is the standard behavior for modern AI chat interfaces. GAIA streams responses from the LLM to the frontend in real time.
How GAIA Uses Inference
GAIA streams LLM inference results to the frontend in real time, giving you immediate feedback as the model generates responses. For background agent tasks like email triage or workflow execution, GAIA runs inference asynchronously so long-running tasks do not block the interface. The choice of LLM provider also lets you balance inference cost against response quality and speed.
