Lightning AI vs Vellum
Compare coding AI Tools
Lightning AI is a cloud development environment for ML projects that provides persistent GPU workspaces called Studios, lets you run notebooks or VS Code in the browser, start and stop resources to save cost, and publish or expose web apps and inference services from the same workspace.
Vellum is an AI agent building platform that combines a prompt playground, evaluation tools, and hosted agent apps so teams can iterate on LLM workflows with debugging and knowledge base support, starting with a free tier and upgrading for more credits.
Feature Tags Comparison
Key Features
- Persistent Studios: Create cloud workspaces that keep your files and environment so you can stop compute and resume later without re setup.
- Browser IDE options: Work in notebooks or connect via VS Code style workflows so coding and debugging happen on the same GPU machine.
- Template launches: Start from ready templates for common AI tasks and reduce time spent wiring environments and dependencies.
- GitHub and GitLab access: Add repositories via SSH and keep code synchronized with your normal review and branching process.
- Web app hosting: Run a web app from a Studio and expose it through a public URL for demos and internal tools and lightweight production use.
- Container deployment: Deploy a container from the platform to package your runtime and make the same artifact runnable across stages.
- Free and Pro plans: Pricing starts at $0 with 50 credits and Pro at $25 with 200 builder credits so solo builders can scale testing
- Prompt playground: Compare models side by side and iterate prompts systematically instead of relying on subjective testing
- Evaluations framework: Run repeatable quality tests at scale to detect regressions and track improvements across prompt versions
- Hosted agent apps: Share working agents with teammates through hosted apps for demos
- reviews
- and stakeholder feedback cycles
Use Cases
- GPU prototyping: Spin up a Studio to train or fine tune models on cloud GPUs and pause and resume work to control spend during iteration.
- Reproducible experiments: Keep a persistent environment for a project so teammates can rerun notebooks with the same packages.
- Demo apps for stakeholders: Host a simple web app that showcases a model and share a public URL for feedback and validation.
- Inference API pilots: Package a model into a container or serving endpoint to test latency and throughput before a full rollout.
- Teaching and workshops: Provide learners a consistent cloud environment so setup time is minimized and sessions start quickly.
- Dataset iteration: Store datasets and checkpoints in Drive and track storage growth with documented free capacity and per GB billing rules.
- Agent prototyping: Build an agent by chatting with AI then refine logic with low code steps and controlled prompt versions
- Prompt iteration: Compare LLM outputs side by side and select prompts that improve accuracy and reduce unwanted variation
- Regression testing: Run evaluations on a saved dataset before release to catch quality drops after model or prompt changes
- RAG apps: Attach a knowledge base and test retrieval behavior with representative questions and strict document scope rules
- Stakeholder demos: Publish hosted agent apps so product and compliance reviewers can test behavior without local setup steps
- Model selection: Evaluate providers and self hosted options with the same tasks to choose the best cost and latency mix for production
