Products, side by side
Algorithmic pairing — assembled from recorded fields, not hand-checked
AI21 Labs
API service
A drop-in endpoint that sits in front of an agent's model calls and cuts token spend — adaptive routing, context compaction, trajectory-aware savings decisions and caching — while validating output quality against coding benchmarks.
Data service
A dedicated model-customization service in which AI21 trains specialized models on a client's own data, with methodology transfer so the client can run subsequent training rounds in-house.
LlamaIndex
API service
Document parsing for LLM pipelines: layout-aware, agentic extraction that turns PDFs, contracts and forms into structured text a retrieval system can index, with an LLM or VLM reading the page when basic parsing is not enough.
Data service
Extracts structured data from complex documents using custom schemas, with field-level confidence scores and citations back to source.
The indexing half of LlamaCloud: intelligent chunking and embedding that turns parsed documents into a searchable knowledge base for agents.
