Frequently Asked Questions About the New AI Chatbots with OpenAI + WOZTELL

14 FAQs about GPT Assistant v1.3.0, Responses API, migration from Assistants API, and AI chatbot configuration in WOZTELL

This article answers the most frequently asked questions about the launch of the new AI chatbots in WOZTELL using GPT Assistant v1.3.0 and OpenAI’s Responses API.

It is intended for customers, partners, and teams that already use WOZTELL or want to start automating conversations across channels such as WhatsApp, Instagram, Facebook Messenger, and Webchat.

Warning

Previously, WOZTELL used configurations based on OpenAI’s Assistants API.

OpenAI has announced that Assistants API is deprecated and that its shutdown is scheduled for August 26, 2026. For this reason, legacy assistants must be migrated to the new chatbots based on Responses API before that date.

1. What are the new WOZTELL AI chatbots?

They are AI assistants connected to OpenAI that can automatically respond to end users from the channels connected to WOZTELL.

They can be used on:

• WhatsApp Business.
• WhatsApp Cloud API.
• Instagram.
• Facebook Messenger.
• Webchat.

They can also be connected to Knowledge Bases, search tools, and external functions to provide more complete responses.

2. What is GPT Assistant v1.3.0?

GPT Assistant v1.3.0 is the WOZTELL extension that allows OpenAI to be connected with WOZTELL conversational channels.

From this extension, you can configure:

• The OpenAI API Key.
• The model that will generate the responses.
• The assistant’s instructions or prompt.
• Tools such as File Search, Web Search, and Function Call.
• Knowledge Bases or Vector Stores.
• Connection to WOZTELL channels.

3. Why is WOZTELL migrating from Assistants API to Responses API?

WOZTELL is migrating because OpenAI has deprecated Assistants API and has defined Responses API as the recommended API for new implementations of AI assistants and agents.

Responses API allows more flexible configuration of context, tools, and model calls. It is also the foundation on which OpenAI is building its new assistant capabilities.

4. Until when will legacy assistants based on Assistants API work?

OpenAI has announced that Assistants API will no longer be available on August 26, 2026.

For this reason, any legacy configuration based on Assistants API must be migrated before that date to avoid service interruptions.

5. What happens if I do not migrate my assistant before August 2026?

If an assistant continues to depend on Assistants API after the shutdown date defined by OpenAI, it may stop working correctly.

To avoid interruptions, it is recommended to migrate in advance to the new configuration based on Responses API.

6. Does the migration change how my customers write on WhatsApp or Instagram?

Not necessarily.

The migration mainly affects the technical configuration of the assistant. The end user will continue writing from the same channel, such as WhatsApp, Instagram, Facebook Messenger, or Webchat.

What changes is the internal architecture used by WOZTELL to connect the chatbot with OpenAI.

7. Which channels are compatible with the new AI chatbots?

The new AI chatbots can be connected to the conversational channels available in WOZTELL, including:

• WhatsApp Business.
• WhatsApp Cloud API.
• Instagram.
• Facebook Messenger.
• Webchat.

The assistant can only be activated on channels that have already been connected in the WOZTELL account.

8. What do I need to configure an AI chatbot in WOZTELL?

To configure an AI chatbot, you need:

• A WOZTELL account.
• At least one channel connected in WOZTELL.
• A valid OpenAI API Key.
• Access to the OpenAI models you want to use.
• A prompt or instructions to define the assistant’s behavior.
• Optionally, documents to create a Knowledge Base.

9. What is an OpenAI API Key?

The API Key is the credential that allows WOZTELL to connect with the customer’s OpenAI account.

Without a valid API Key, WOZTELL cannot send messages to the model or generate automatic responses.

The API Key must be kept private. If it is exposed, it should be revoked in OpenAI and replaced with a new one.

10. Which OpenAI model should I use?

It depends on the use case.

The exact list of available models depends on the connected OpenAI account.

11. What is the prompt or Instructions?

The prompt or Instructions defines how the assistant should behave.

It should indicate:

• What role the assistant has.
• What tone it should use.
• What topics it can answer.
• What topics it should avoid.
• When it should escalate to a human agent.
• What information it should ask the user for.

A clear prompt helps reduce errors, invented answers, and out-of-scope conversations.

12. What is a Knowledge Base?

A Knowledge Base is a set of documents that the assistant can consult before responding.

It may include:

• FAQs.
• Product guides.
• Technical documentation.
• Internal processes.
• Commercial material.
• Support policies.

The clearer and more up to date the documentation is, the better the assistant’s responses will be.

13. What is the difference between Knowledge Base, Vector Store, and File Search?

They are related concepts, but they do not mean exactly the same thing.

• Knowledge Base: the set of documents that the assistant can consult.
• Vector Store: the technical container where those documents are processed and indexed.
• File Search: the tool that allows the assistant to search inside the Vector Store.

In short: the Knowledge Base is the library, the Vector Store is the technical container, and File Search is the tool that searches inside that library.

14. How can I control the chatbot’s cost?

The cost mainly depends on the model, the tokens processed, and the tools used.

To control costs, it is recommended to:

• Use efficient models for high-volume use cases.
• Limit the conversation history sent to the model.
• Avoid excessively long responses.
• Use Web Search only when necessary.
• Keep the Knowledge Base clean and well organized.
• Avoid uploading duplicated or contradictory documents.
• Escalate to a human in complex cases.
• Review logs and usage periodically.

Summary

The new WOZTELL AI chatbots based on OpenAI and Responses API make it possible to create more flexible assistants, connected to multiple channels and ready to use tools such as File Search, Web Search, and Function Call.

This new architecture progressively replaces previous configurations based on Assistants API. Since OpenAI has announced the shutdown of Assistants API for August 26, 2026, it is recommended to migrate any legacy configuration before that date.

For a correct configuration, it is important to review the model, prompt, Knowledge Base, channel, active tools, cost control, and human escalation rules.
