Context.ai (Contextual AI) provides platform primitives as component APIs with usage-based pricing for AI teams building RAG applications. The platform includes a multi-stage document understanding pipeline for converting unstructured content into AI-ready formats, a state-of-the-art instruction-following reranker, and an evaluation-optimized model for preference scoring, direct scoring, and natural language unit test evaluation. Designed for teams that need flexibility with their existing RAG architecture.

Reranking API from Cohere for improving search and retrieval quality.
Embedding and reranking models for RAG applications.
Open-source framework for evaluating RAG pipeline quality.
Data framework for LLM applications with evaluation tools.
Context.ai takes a smart approach by offering component APIs rather than an all-in-one platform, letting AI teams plug in exactly what they need. The instruction-following reranker and evaluation model address two critical needs in RAG development: better retrieval and reliable quality measurement. The usage-based pricing aligns costs with value. For AI engineering teams building production RAG applications who need to improve specific pipeline stages without replacing their entire stack, Context.ai provides surgical improvements.
