Apply verification, tool limitation, iterative development, performance tracking, and infrastructure awareness to safely and efficiently use AI FDE in Palantir Foundry.

AI FDE (Foundry Data Engineering) can accelerate development, but it must be used responsibly. Follow these best‑practice guidelines to keep your pipelines reliable, secure, and performant.

Verify resources and procedures

  • Review all generated code for correctness and compliance with organizational standards before deploying to production.
  • Test transformation logic with representative sample data to confirm it behaves as expected under different conditions.
  • AI FDE creates changes on a branch by default and submits them as a Global Branch proposal or a code‑repository pull request for review.
  • Depending on the tool and its configuration, AI FDE may require tool approval before acting. Make sure you understand the intended action and verify the tool being used before granting permission.

Limit tools and context

  • Provide the model only the essential context and required tools for the task at hand.
  • Excessive or irrelevant context can cause suboptimal or incorrect actions.
  • Restricting tools reduces confusion, improves efficiency and accuracy, and enhances security by minimizing exposure to sensitive operations or data.

Decompose problems and use iterative development

  • Break complex operations into smaller, manageable steps. Start with a basic structure and add complexity incrementally, verifying each component before proceeding.
  • AI FDE excels at rapid prototyping, enabling quick exploration of alternative approaches.
  • For production‑grade solutions, combine AI‑generated foundations with manual development for fine‑tuning and optimization.

Track performance with AIP Evals

  • Use AIP Evals to evaluate and monitor the performance of functions created or modified by AI FDE.
  • Build evaluation suites for your LLM‑backed functions to measure impact over time and compare different implementations.
  • Quantitative feedback from AIP Evals is especially valuable during iterative development, helping you determine whether changes improve or degrade performance.

Consider infrastructure constraints

AI FDE operates at a pace far faster than human developers, often executing dozens of operations within minutes and running multiple sessions in parallel. This can expose infrastructure bottlenecks that are invisible under typical human‑driven workflows.

Key areas to assess:

  • Storage read/write throughput
  • Compute resources, especially GPU availability
  • Overall storage capacity

Plan for high‑frequency parallel operations, sustained compute loads, increased network activity, and expanded storage requirements to avoid performance degradation.


Key takeaways

  • Always verify AI‑generated code and test transformations with realistic data.
  • Limit context and tools to only what is necessary for the task.
  • Decompose large problems and adopt an iterative, hybrid development approach.
  • Leverage AIP Evals to obtain quantitative performance feedback.
  • Assess and provision infrastructure to handle the rapid, parallel nature of AI FDE workloads.

Stage 1: Foundations

  • Understand AI FDE purpose and its branch‑proposal workflow in Foundry.
  • Get familiar with enabling AI FDE and basic transformation generation.

Stage 2: Safe Development Practices

  • Verify generated code and test transformations with representative sample data.
  • Limit the tools and context supplied to the model to only what is needed.
  • Adopt iterative development: decompose complex tasks and incrementally add complexity.

Stage 3: Performance & Scale

  • Use AIP Evals to create evaluation suites that track function performance over time.
  • Monitor and plan for infrastructure constraints such as storage I/O, compute/GPU load, and network activity during high‑frequency AI FDE sessions.

Get hands-on — step by step

  1. Create a sandbox Foundry project and enable the AI FDE feature in the project settings.
  2. Write a simple transformation (e.g., add a new column) using the AI FDE prompt UI.
  3. Review the generated branch proposal: open the Global Branch, inspect the code, and run unit tests on a small sample dataset.
  4. Verify and approve the changes only after confirming they meet your organization’s coding standards.
  5. Limit tools: in the AI FDE configuration, deselect any unnecessary toolkits so the model only has access to the data and functions required for the task.
  6. Run an AIP Eval suite: use the Foundry UI to create an eval that compares output quality before and after the AI‑generated change.
  7. Monitor infrastructure: open the Foundry monitoring dashboard, watch storage read/write and GPU usage while the AI FDE job runs, and adjust resource quotas if needed.
  8. Iterate: break a larger data‑pipeline change into smaller steps, repeat steps 2‑7 for each step, and merge only after each passes verification.
