Citations it wasn’t given come out

Lornos checks every ID as the answer streams. One it didn’t retrieve is removed, and your user is told.

What the model wrote: Open Sales and click Record sale [record-a-sale.md#1.0]. You can also undo a sale from Reports ~~[undo-a-sale.md#0.0]~~.
What your user gets: Open Sales and click Record sale [record-a-sale.md#1.0]. You can also undo a sale from Reports.; Citation check: removed 1 unverified source ID; statements that relied on them are not verified.

An example answer written to show the check. undo-a-sale.md#0.0 was not retrieved for this question. The note is the text Lornos adds.

Every request shows its timings

Each request reports how long finding the passages took and how long the answer took to write, so you can see where your time goes.

One request to our internal demo workspace42 articles, 280 passages

Finding the passages: 4 ms
First words on screen: 1.6 s
Full answer written: 3.30 s

Your timings will differ. Finding passages depends on how much your workspace holds, and writing depends mostly on how long the answer is. Either way the answer streams, so your user starts reading before it is finished.

Each workspace keeps its own index

A question searches only the workspace that asked it. An empty one says so, and never borrows another’s passages.

Answer: This workspace has no searchable sources yet. Add documents on the Sources page, then ask again.

The same question in two workspaces. The empty workspace’s reply is the fixed text Lornos sends, with no model call and no citations. Deleting a source removes its passages, so no later answer can cite it.

Before you ask for access

The rest is in the help center.

What can I upload?: Markdown, plain text, HTML, PDF and Word, up to 25 MB a file: .md .markdown .mdx .txt .html .htm .pdf .docx
How does my code ask a question?: POST /api/chat with an API key that has the chat scope. The answer streams back with its citations.
Are follow-up questions grounded too?: Yes. Each question gets fresh retrieval. Earlier answers only tell Lornos what “it” refers to, never what to cite.
How many questions can I ask?: 30 a minute and 500 a day per workspace, counting the playground and every key. Past that you get a 429 with a Retry-After header.
When can I start?: Lornos is in private beta. We approve early-access requests into new workspaces and write to you once.
