# Limits

## Enforced ceilings

These are the ceilings Vistazo enforces. Most people never meet one, and when something is refused,
the number is here.

## Capacity

| | Limit |
|---|---|
| Dashboards and notebooks you own | Unlimited |
| Storage for uploaded files | 1 GB for each member |
| Widgets on one dashboard | 100, not counting archived widgets |
| Workspaces you can create | 5, your personal workspace included |
| Workspaces you can join | Unlimited |
| People in a shared workspace | 10, counting pending invitations and not counting guests |
| Workspaces whose shares appear in your lists and search | 20, the ones you opened or joined most recently |

A share from any further workspace still opens from its email, and opening it brings that workspace
back into your lists. Storage, inference and compute are counted for each member
([Usage](/docs/billing/usage)).

Storage and the number of people are the standard early-access figures, and some workspaces are set up
with more or no limit ([Plans](/docs/billing/plans)). **Settings → Usage** shows your storage, and the
footer of **Settings → Members** shows the workspace's limit on people.

## Refresh

| | Limit |
|---|---|
| Shortest schedule interval | 15 minutes |
| Minute intervals offered | 15, 30 and 45 |
| How long published data is kept | 28 days. After that the dashboard reads as expired |
| Automatic chart repairs | 10 attempts per widget in 6 hours, on any refresh. A schedule repairs one chart at most once a day |
| Refreshes and filtered views in the app | 300 per person per hour |
| Dashboards on a schedule | 25 per person in each workspace. Past that, the 25 oldest run |

## Notebooks

| | Limit |
|---|---|
| Notebooks in a workspace | 200, not counting archived notebooks |
| Notebook running time | 8 hours per person in a 24-hour window, across all your workspaces |
| Notebooks running at once | 3 per workspace |
| Kernel starts and restarts | 60 per person per hour |
| Notebooks on a schedule | 25 per person in each workspace |
| Cells in one notebook | 50 |
| Text in one notebook | 100,000 characters |
| One cell's running time | 9 minutes, then the cell is interrupted |
| Cell runs | 600 per person per hour |
| Kernels open at once | 2 per person, one for each notebook |
| Kernel memory | 1.8 GB |
| Idle kernel | Can be reclaimed after 15 minutes with no run |
| Importing a .ipynb file | 10 MB from the app, 1.5 MB through your agent |
| Parameters in one notebook | 20 |
| Your own parameter values for one run | 16 KB in total |
| One cell's output with your own values | 4 MB |

## Chat

| | Limit |
|---|---|
| Runs at once | 3 per person, and 1 per conversation |
| Longest run | 9 minutes |
| Files on one message | 10 |
| One uploaded image (PNG, JPEG, WebP or GIF) | 10 MB |
| One uploaded document (PDF, CSV, TSV, Excel, text, Markdown or JSON) | 20 MB |
| PDF pages read | 200 |
| PDF pages read by a vision model | 20 |
| Chart draft | 1,000 rows and 150 KB |

A draft over either chart limit is refused instead of trimmed, so a draft well under 1,000 rows can
still be too large. A trimmed draft would not match the widget it becomes, which runs against the full
data on its first refresh.

## Workspace knowledge

| | Limit |
|---|---|
| Metrics in a workspace | 500. Past that, new ones are not added |
| Dimensions in a workspace | 300. Past that, new ones are not added |
| One note | 1,000 characters |
| Notes on one metric | 100, and 50 of them can be yours. Archived notes don't count |
| Notes saved | 20 per person per minute |

See [Workspace knowledge](/docs/chat/knowledge).

## Data sources

| | Limit |
|---|---|
| Requests to Vistazo's own tools | 120 per person per minute |
| Requests to one curated source | 60 per person per minute |
| Requests to Google Sheets | 30 per minute for each Google account |
| One Google Sheets read | 2 MB or 100,000 rows. A longer read says which row to continue from |
| One response from a source | 5 MB |
| One fetch step | 3 minutes |

## Connected agents

| | Limit |
|---|---|
| Requests in progress at once | 16 per person. One more is refused and told to retry after one second |
| Data fetches by one MCP connection | 300 per hour, shared by its source tool calls, refreshes, explores and pipeline tests |
| Access token | 1 hour, renewed automatically |
| Refresh token | 30 days, extended each time it is used |
