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.
Developer tool
AI coding assistant, marketed in Chinese as Wenxin Kuaima, that generates code, unit tests and comments and answers programming questions through IDE plugins.
Baidu's open-source deep learning framework for building, training and deploying machine learning and large models, anchoring an ecosystem that includes AI Studio, EasyDL and EasyEdge.
Platform
Baidu's open autonomous-driving developer platform offering cloud simulation, a fleet R&D cloud, high-precision mapping and calibration services and the D-KIT hardware development kit, distinct from the Apollo Go robotaxi service.
Data intelligence platform that converts unstructured enterprise data into agent-comprehensible formats and business-ontology models, with a Data Agent for supply-chain, retail, LLM-training, autonomous-driving and RAG use cases.
Weights & Biases
API service
Hosted inference service for open-source and commercial LLMs (OpenAI, Qwen, Llama, Kimi, Phi, DeepSeek, Z.AI) without managing infrastructure.
Developer tool
Tracing, evaluation and production monitoring for LLM and agent applications, capturing each call so prompts and outputs can be scored over time.
Platform
Experiment tracking for model training runs, recording hyperparameters, metrics and artifacts so runs can be compared, swept and reproduced.
Curated central repository providing versioning, aliases, lineage tracking and governance for models and datasets across the ML lifecycle.
Managed reinforcement-learning fine-tuning service for LLMs on CoreWeave's managed GPU cluster, billed per-token for rollouts with automatic scale-to-zero.
Serverless supervised fine-tuning for LLMs on CoreWeave's managed GPU cluster, run alongside Serverless RL in a unified workflow via the Agent Reinforcement Trainer (ART) API.
No counterpart
Baidu sells these in a stack layer with no product recorded for Weights & Biases yet — nothing on the other side to compare them against.
Application
Baidu's driverless ride-hailing service, operating in Chinese cities under the name Luobo Kuaipao.
Baidu's consumer assistant for chat, writing and image generation, built on the ERNIE models.
Infrastructure service
Baidu AI Cloud's heterogeneous AI-computing platform providing large-scale GPU and Kunlun-chip clusters, distributed training acceleration and inference serving for large-model workloads.
Model API
Baidu AI Cloud platform that serves ERNIE and third-party models with fine-tuning and application tooling.
