# Inference Modes Vanna supports a variety of flavors of inference to suit all sorts of use-cases depending on demands for speed, cost, verifiability, and security. * **Vanilla Inference** * Fast execution of inference through leveraging GPU hardware acceleration and transaction parallelization * **zkML Inference** * Inference where the inference node also subsequently generates a zkML proof with EZKL. The proof is then validated by validator nodes on the Vanna Network for an absolute guarantee of security. * **zkFP Inference** * Inference where the inference computation is assumed to be honest, but makes the transaction available for challenge. If challenged, the challenger puts up a stake and the inference node must provide a zkML proof proving the result. * **opML Inference** * Inference where the inference computation is assumed to be honest, but makes the transaction available for challenge. If challenged, the challenger puts up a stake and a bisection verification game is played to see whether the inference node was honest. * **TEE Inference** * Run a private enclave node with the model stored locally, so the model weights remain private. Inference requests for the model are routed to that node, with a zkML proof subsequently generated and verified by the Vanna Network. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.vannalabs.ai/vanna-network/inference-modes.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
