Our tech stack is pretty impressive! We use a combination of proprietary and open-source LLMs, including our own pplx-7b and pplx-70b models, as well as GPT-4, Claude 3, and others.

We also leverage NVIDIA's inference stack, including Triton Inference Server and H100 GPUs, to handle over 400 million search queries monthly.

For Deep Research, we've developed a chain-of-thought based agent that performs multiple searches and synthesizes findings into detailed reports.
