Today, I’m thrilled to share with you our latest improvement in the CustomGPT.ai platform: Inline Citations — numbered inline citations right in the AI agent’s response!
Traditional citations are great — they provide observability and build trust with users — and inline citations bring them to the next level by offering top-notch user experience.
Each AI agent’s response is now referenced right there in the text, with source material just one click away!
Inline citations are now the default for all new CustomGPT.ai projects (on all our plans!), but for existing projects, you need to activate them manually in your project settings.

Why are citations important for AI agents?
- Transparency by providing clear and precise sources for each generated response.
- Build trust with your users by showing them the source of the AI response.
- Reliable sources empower users to make better-informed decisions.

How citations work in CustomGPT.ai?
- Everything starts with building the agent and providing it with high quality ground-truth data!
- When the agent generates the answer, it will use parts of the provided context material.
- Used context material will be referenced, providing observability and confidence to users.

Frequently Asked Questions
How do inline citations improve trust in AI responses, not just transparency?
Inline citations improve trust because you can verify claims immediately while reading the answer. Numbered references appear directly in the response, and source material is one click away. That makes it easier to make informed decisions instead of relying on unsupported output.
Why do citations sometimes point to a broad section instead of the exact sentence I expected?
Citation precision depends on the quality and structure of the source content your agent uses. Responses are grounded in parts of the provided context, and those used context segments are what get referenced. If you want tighter citations, start by improving source data quality and clarity.
Can I attach a URL when I upload a file by API so citation clicks open that original link?
The confirmed behavior is that inline citations provide one-click access to source material. The announcement does not specify API-level URL mapping controls for custom citation destinations, so verify that capability in the latest API documentation before implementation.
If my knowledge base is in SharePoint, can inline citations link back to the original SharePoint files?
Inline citations are designed to reference the source material used in the response, with one-click access from the answer text. SharePoint-specific linking behavior is not detailed in the announcement, so validate connector output in your own setup before production rollout.
How do inline citations work when one answer uses multiple documents?
Inline citations appear as numbered references inside the answer text, tied to the source material used to generate that response. When multiple documents are used, this format helps you see support near each relevant statement instead of relying on a separate citation block.
Can users override citation behavior by pasting long instruction prompts into the chat?
Inline citations are a platform feature rather than a user formatting preference. For new projects, they are enabled by default across plans. For existing projects, you need to enable them in project settings, then test outputs to confirm citations appear as expected.
