B4X Requires Chilkat v11.2.0+

Prove Stateful Multi-Turn Conversation

See more AI Examples

This example is to prove that the 2nd request in a conversation is part of a stateful multi-turn conversation. The 2nd request asks for information provided in the 1st request. B4X

Dim success As Boolean = False

'  This example assumes the Chilkat API to have been previously unlocked.
'  See Global Unlock Sample for sample code.

Dim ai As ChilkatAi

'  The provider can be "openai", "google", "claude", "deepseek", "xai", or "perplexity".
'  Support for additional providers will be added in future versions of Chilkat.

ai.ApiKey = "MY_API_KEY"

'  Choose a model.

'  Create a new conversation to be maintained locally in memory.
'  If the conversation is the first to be created, it is also automatically selected.
