One open-source AI gateway for 100+ LLM providers
Call 100+ providers and 1,800+ models using one request format, so you can swap models without changing application code.
Issue scoped keys per team, project or app, set monthly spend caps and see exactly who is driving usage and cost.
Distribute traffic across deployments, retry on failure and automatically fall back to another model or provider when one goes down.
Dashboards for request volume, tokens and cost per model, with support for logging and analytics integrations.

AI-native ecommerce search and product discovery trained on your catalog
Trains a dedicated AI model on your real catalog and shopper behavior, with no shared LLM and no synthetic data, so relevance matches how your customers actually shop.
Goes beyond keyword matching with instant indexing, semantic relevance, typo tolerance, and multilingual comprehension across queries.
LLM-based image search is integrated into the search model, supporting reverse image and visual discovery flows that legacy keyword engines cannot match.
Shifts in real time between results, carousels, guided discovery, and conversational search based on shopper intent, context, and behavior.
Provides a massive hosted model catalog with instant access, but requires trusting a third-party platform instead of self-hosting.
