Deploy the Next.js application to Vercel and ensure it is bug free. Verify production build and performance. Ensure proper environment configurations for deployment.

Implement AI integrations (e.g., Google GeminiAI, LangChain, GPT-based models, etc.) into the app for various purposes, such as semantic search and chatbots. Set up AI agents capable of handling user queries and providing relevant answers. Configure and integrate semantic search for improved question-answer retrieval or similar use cases. Optimize AI agents to improve their performance and relevance.

Register and configure a custom domain for the application. Ensure that DNS settings are correctly configured to point to Vercel. Verify that the domain is secure with an SSL certificate.

Create a public or private GitHub repository containing the source code of the Next.js app, AI integrations, and related configurations. Set up proper version control and branching strategy. Ensure the repository is well-maintained with regular commits and proper structure.

Provide clear documentation on how the application is set up, deployed, and used. Include instructions for setting up the development environment, configuring AI integrations, and deploying to Vercel. Document any APIs, configurations, and tools used in the project (e.g., setup of AI agents, semantic search, etc.). Include setup steps for custom domain configuration and any security settings required.
