Products, side by side
Algorithmic pairing — assembled from recorded fields, not hand-checked
Crusoe
API service
Hosted endpoints serving open-weight and customer-supplied models on Crusoe's own hardware, billed per token or as dedicated hourly deployments.
Managed LoRA-based fine-tuning of open-weight models, billed per token of training data rather than per GPU-hour.
Developer tool
Unified operations and observability console for GPU fleets running AI workloads on Crusoe Cloud.
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.
No counterpart
Crusoe sells these in a stack layer with no product recorded for Weights & Biases yet — nothing on the other side to compare them against.
Infrastructure service
GPU cloud running on Crusoe's own energy-colocated data centres, rented by the hour.
Crusoe Cloud GPU capacity delivered at edge and sovereign locations via prefabricated Crusoe Spark modular units.
Hardware
Prefabricated modular AI data centre integrating power, cooling, fire suppression and GPU racks for deployment at a customer site.
Weights & Biases sells these in a stack layer with no product recorded for Crusoe yet — nothing on the other side to compare them against.
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.
