Mistral AI
API service
SOTA document-extraction API (OCR 4) returning bounding boxes, block classification and confidence scores across 170 languages; the same endpoint's Document AI mode adds a no-code, schema-driven layer on top for structured extraction.
Platform
Frontier-grade infrastructure and orchestration for training and serving models at scale.
Turn institutional knowledge into custom enterprise LLMs without managing the infrastructure.
Weights & Biases
API service
Hosted inference service for open-source and commercial LLMs (OpenAI, Qwen, Llama, Kimi, Phi, DeepSeek, Z.AI) without managing infrastructure.
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.
