Introducing the Parallel Chat API - a low latency web research API for web based LLM completions. The Parallel Chat API returns completions in text and structured JSON format, and is OpenAI Chat Completions compatible.

The Chat API returns OpenAI ChatCompletions compatible streaming text and JSON with the low latency your interactive apps need. It is built with the same obsession for price-performance that we’ve demonstrated with the Task API[Task API]($https://parallel.ai/blog/parallel-task-api).

Last year, we started building our own web crawler and index, recognizing that AIs need native infrastructure to query and reason over the web. The Chat API answers instantly using our index, while the Task API combines our index with real-time web crawling for maximum accuracy and the freshest data. Both APIs return comprehensive citations so you can always verify responses.
