As a developer wanting a micro bot design, is it still recommend that I go with PVA instead of Bot Framework SDK?

Scenario/Plan:

I am a software developer tasked with creating a chat bot for my company. The idea is that the bot starts off in a specific scenario, and then is expanded upon over time.

My goal is to create a kind of micro bot structure. So I will create many bots that all have a single purpose. Ex: I will have a Q/A bot, a troubleshooting bot, an error handling bot, etc. The goal is to be able to pick and choose as we create bots for specific purposes.

Question:

Is it still recommended to go with PVA, go pure Bot Framework SDK, or a combination? Also, is bot framework SDK still actively developed on?

Last question! Do you still recommend using PVA for the following scenarios?
1) Goal is to use Chat GPT or openAi GPT to determine intent
2) Goal is to use Azure's Conversational Understanding Language to determine intent, does PVA still make sense?

You have it correct. Check the releases, the last major update was back in July of last year.

Just to make sure, by PV you meant PVA I assume? So you would create all of your bots in PVA and use the bot framework skill to route to other PVA bots? And only create skills when PVA can't do something? So basically the framework is just used for routing and doing things PVA can't do?

Glad it's still being updated! It's been on v4 for 2 years and when I was looking at github, I noticed that it was mostly last modified 2 years ago. Is this still the correct github link or am I reading it wrong? https://github.com/microsoft/botframework-sdk

For the best long-term investment, you should start with PV and call these subordinate PVA bots via a Bot Framework routing bot using skills. Bot Framework is still seeing regular updates, and if you find that you do not need to do the spoke and hub model of bot design within PVA, it will be easier to stay with future investments by having these experiences already in PVA.

In your case, I would start simply with a PVA bot, and expand only when it makes sense from a project management standpoint.
