LLM Batching & Async Inference: Cut Costs on High-Volume AI
Blog post from NeuralTrust
LLM batch inference is a method of processing multiple AI requests as a single job asynchronously, rather than handling each request in real time, which is particularly beneficial for non-urgent tasks where immediate responses are not necessary. OpenAI and Anthropic offer batch processing solutions that provide a 50% cost discount compared to synchronous processing, with results typically delivered within 24 hours. This approach is ideal for tasks like classification, document processing, and dataset labeling, where a human is not waiting for an immediate result. By using batch inference, organizations can significantly reduce AI processing costs, as it comes from a separate rate limit pool and does not affect the synchronous quota. However, it is unsuitable for real-time interactions such as live chat or fraud detection, where immediate feedback is critical. Implementing batch processing requires error recovery strategies, such as per-request status checks and retry logic for failed items, to handle incomplete batch jobs effectively.
