  "textContent": "Over the past year, AI development has become dramatically faster. With modern APIs and foundation models, teams can build chatbots, copilots, recommendation engines, and automation workflows in days instead of months.\n\nBut shipping a demo is not the same as shipping a product.\n\nMany teams discover that the real challenges begin after the first prototype:\n\n  * Managing API costs as usage grows\n  * Handling hallucinations and unreliable outputs\n  * Maintaining context across conversations\n  * Integrating AI into existing business systems\n  * Monitoring performance and model quality\n  * Ensuring security, compliance, and data privacy\n\n\n\nThe conversation around AI often focuses on models, benchmarks, and prompts. In practice, successful AI products depend just as much on architecture, observability, evaluation pipelines, and user experience.\n\nFor developers building with AI APIs today:\n\n**What has been your biggest challenge after the initial prototype stage?**\n\nWas it cost, reliability, scaling, user adoption, data quality, or something else entirely?\n\nI’m interested in hearing real-world experiences from teams that have moved beyond demos and into production.",
