    It can, though the trigger is narrower than many assume. If you build an AI system on top of a third-party model and place it on the market under your own name, you are generally the provider of that system, even if you never modified the model. Under Article 25, a deployer also becomes a provider if it puts its name or trademark on a high-risk system, substantially modifies one, or changes a system’s purpose so it becomes high-risk. Provider status brings the heavy high-risk obligations, audit logs, technical documentation, and human oversight, with fines up to €15M or 3% of global turnover under Article 99. On timing: in June 2026 the EU adopted the Digital Omnibus, moving the high-risk deadline for Annex III systems to December 2, 2027, and for Annex I embedded systems to August 2, 2028.

    Measure outcomes, not consumption. The two most useful metrics are time from AI output to verified working code, and the rate of AI-authored code that fails in production. Track token spend as a cost constraint against margin, not as a productivity score. Token volume tells you how much AI was used, not whether it produced anything reliable.

    Around 33%, according to Saritasa’s survey of 500-plus US IT professionals. The cost is compounding because the specialist talent pool for older stacks like COBOL and legacy Java is shrinking, which raises retention costs and modification risk.

    Often you can, and some teams are displacing $20,000-plus in annual vendor spend this way. The catch is that an AI agent can build the first version quickly, but reliability, observability, and security over the tool’s full life are the real cost and do not appear in the initial build. Build when the tool is core to your workflow and you can own it long term. Buy when it is undifferentiated and someone else will maintain it better.

    The data layer. Real-time, clean, continuous data pipelines are a prerequisite for reliable AI features. Most mid-market companies run warehouses built for periodic reporting, which produce stale or inconsistent inputs. Fix the pipeline before layering models or agents on top.
