AI agents promise powerful ways to streamline operations, lower costs, and boost productivity. CoreWeave Cloud is purpose built to help you deploy agents in production, train and iterate on them with company-specific data so they meet your reliability and performance requirements.
Agents offer endless business opportunities, from enhancing customer support to innovating product designs and optimizing supply chains. But it’s rare that you can simply plug and play pre-trained foundation models or AI copilots into existing workflows. To be production ready for real users, you need to customize the LLMs for your specific task and build an agent harness around them to perform business tasks reliably, safely, and efficiently. Building AI agents requires a new set of tools purpose built for experimentation and rapid iteration.
Clearly visualize complex agent rollouts and gain insights into agent behavior. Evaluate agents quickly using pre-built, third-party, or homegrown scorers—and shorten the iteration cycle with every run.
Improve reliability, latency, and cost-efficiency for production workflows by fine-tuning pre-trained LLMs on your company’s proprietary data. Tailor them for specific agentic tasks, and enable your agents to learn continuously on the job to exceed user expectations.
Mitigate the impact of hallucinations and prompt attacks. We help you implement effective guardrails that control your agent’s behavior in real time. It also helps catch harmful edge cases in production and add them to your evaluation dataset for the next iteration.
Explore models and prompts in the W&B Weave Playground, then prototype your agent with Weave tracing for visibility and quick debugging. Post-train the agent using Serverless RL and iterate with experiments and Weave Evaluations. Observe and refine agent behavior in production with Weave Monitors.
CoreWeave Cloud accelerates every stage of AI development with purpose-built infrastructure, high-performance data systems, and Mission Control enabling intelligent orchestration. From training to inference, it delivers unmatched speed, scalability, and reliability. With integrated security, observability, and expert support, CoreWeave empowers every AI pioneer to bring breakthroughs to market at light speed.
CoreWeave acquired Weights & Biases to extend its AI cloud into the full AI development stack, giving teams everything they need to build, train, and deploy production-grade AI agents. Weights & Biases powers over 1,500 organizations, including 30+ foundation model builders, to bring AI from research to production faster.
With Weights & Biases, you can:
W&B Weave helps teams evaluate, monitor, and iterate on agents and deliver them in production with confidence. W&B Training and W&B Inference together offer Serverless RL to post-train and run agents without the burden of provisioning and managing infrastructure.
Use Weave’s flexible evaluation framework to measure the impact of improvements across multiple dimensions including accuracy, latency, cost, and user experience. Centrally track evaluation results for reproducibility, collaboration, and rapid iteration.
W&B Weave has been great, not just tracking results and logging experiments, but evaluating inputs and outputs, fixing bugs faster, and giving us great metrics.

Woven by Toyota achieved a 10x increase in triage speed and scale with AutoTriage, a video AI agent that automates bug classification in their autonomous driving development workflow. Their team used W&B Weave to track experiments, evaluate video inputs and outputs, identify bugs faster, and analyze metrics like weighted precision and recall.
CoreWeave is purpose-built for large-scale AI with bare-metal NVIDIA GPU clusters, low-latency networking, and intelligent orchestration that keep agents training and serving at full throttle. Combined with Weights & Biases, you get the full stack: infrastructure, tooling, and visibility from experiment to production.
Pre-trained models are powerful but generic. To work reliably in production, agents need to be fine-tuned with your proprietary data and optimized for your specific workflows. CoreWeave and W&B give you the tools to adapt, evaluate, and scale those models safely and efficiently.
Weights & Biases provides a full development layer for AI agents—from Weave Evaluations for benchmarking, to Serverless RL for post-training, and Weave Monitors for live performance tracking. Together, they make it easy to iterate, safeguard, and productionize agents with confidence. Weights & Biases provides a complete development and evaluation layer for AI agents—from Weave Evaluations for benchmarking and scoring, to Serverless Reinforcement Learning for fine-tuning, and Weave Monitors for live performance tracking. Together, these tools make it easy to iterate, safeguard, and productionize agents with confidence, while CoreWeave provides the runtime infrastructure to train and serve them at scale.
CoreWeave’s infrastructure delivers ultra-low latency, 97% goodput, and up to 20% higher GPU utilization than other AI clouds. Automated node recovery, topology-aware scheduling, and high-throughput networking keep workloads stable, even at massive scale.
W&B Weave helps you implement real-time guardrails to detect and mitigate hallucinations, prompt attacks, and harmful outputs. You can flag and retrain on problematic cases instantly, ensuring each iteration strengthens safety and performance.
Over 1,500 teams—including 30+ foundation model builders and leaders like Woven by Toyota—use CoreWeave and Weights & Biases to build, train, and deploy AI agents that perform reliably in production.
This webinar dives deep into how LlamaIndex’s modular, composable framework and Weights & Biases’ eval-driven development platform can help you move faster and smarter.
