Inference chip
Also written: Inference ASIC, Inference Application-Specific Integrated Circuit
A specialized chip for running trained AI models efficiently, distinct from training chips.
An inference chip is a type of computer processor built to run artificial intelligence programs that have already been trained. Think of it like a specialized engine designed for one task: taking an AI model and producing an output, such as generating text or an image.
These chips are different from the ones used to train AI models, which require massive amounts of computation to learn from data. Inference chips focus on speed and efficiency for the final step of using the AI.
An inference chip is a hardware accelerator optimized for the forward pass of a trained neural network. Its architecture prioritizes low latency and high throughput for executing AI models, often employing techniques like reduced precision arithmetic and specialized matrix multiplication units. This contrasts with training hardware, which demands high memory bandwidth and computational power for backpropagation and gradient updates.
OpenAI's recent announcement highlights the growing importance of custom hardware for AI. As AI models become more complex and widely deployed, efficient inference is crucial for scaling services and reducing operational costs.
