The timeline for AI development is quite different in each case, from the huge projects with a high level of complexity to the narrow use cases for AI solutions. The process normally lasts from a few months to more than a year.
Here is the approximate estimation. The first step is the discovery and planning, which are needed to outline the product goals, its exact specifications, and user journeys. Those can take from a few weeks to a few months.
The next stage is design and development. These refer to creating the AI models, using cloud services, implementing them into your existing business ecosystem, and then testing. It is impossible to say even the approximate length of these periods because it depends on the project's complexity and your needs. It can take a couple of months if the product is relatively simple and up to a few years.
We'd say about the support here as well. It is ongoing as long as your product exists.
It is also significant to mention that these timelines are just approximate guesses. The duration of an AI development project may vary due to multiple factors, including the state of your data, the complexity level of AI models you will use, and the extent of AI integration in your software or system.
