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.
Model API
Hosted developer platform providing API/SDK access to AI21's Jamba foundation models with metered token pricing, a playground, file library, and web/file search tools.
Baidu
API service
Remote identity-authentication API combining ID-card OCR, liveness detection resistant to deepfakes/3D masks/synthetic faces, and facial comparison against authoritative government databases; mobile SDK, H5 and cloud access.
Image-recognition API family identifying over 100,000 object/scene types, plus specialised plant (20,000+ species), animal (8,000+ species), vehicle and logo (20,000+ brand) recognition, via public cloud or private deployment.
OCR service recognizing printed/handwritten documents, images, tables, stamps and QR codes across 20+ languages, via public cloud API, offline SDK or private deployment.
Model API
Baidu AI Cloud platform that serves ERNIE and third-party models with fine-tuning and application tooling.
