AI application timelines depend on the use case, data readiness, model integration, retrieval, tool integrations, evaluation and production infrastructure.

AI Proof of ConceptAI Planning

A focused proof of concept can validate the technical approach before building the complete production system.

Key Takeaways at a Glance:

  • AI development is not only model integration.
  • Data preparation can affect project timelines.
  • Production AI requires evaluation and monitoring.

The timeline for an AI application depends heavily on what the AI needs to do.

A simple AI-assisted feature can be implemented much faster than a production RAG, agent or machine learning platform.

Data preparation, integrations and evaluation can become major parts of the development effort.
