# AI usage and limits

Each plan includes a monthly allowance of AI credits for Hamming on Phloem
managed models.

| Plan | AI credits a month |
|---|---|
| Starter | 200 |
| Enterprise | unlimited — and your own [AI provider](https://phloem.ai/docs/workspace/ai-provider/), billed to you |

A credit is a fixed amount of model work, counted in tokens, not dollars. A
price change never changes your count.

| One credit is | |
|---|---|
| input tokens | 10,000 |
| tokens read from the cache | 100,000 |
| output tokens | 2,500 |

Credits reset on the 1st of each calendar month, UTC.

## When they run out

New messages to Hamming are refused with a reason: credits used this month and
the reset date. In Slack and Teams, that is the reply in the thread. Everything
else — Live data, Replay, recording and export — keeps working. To raise the
limit, contact Phloem.

## Where usage shows

In your Phloem account:

| Page | Shows |
|---|---|
| **Plan & usage** | **This month**: **AI credits** used of the limit, beside **Devices** and **Cloud storage**, and when credits reset |
| **AI** › **Usage** | a **Period** (**Today**, **This month**, **Last month**): **Credits this month**, **Total tokens**, **Model calls**, **Input tokens**, **Output tokens**; **Usage by model**; **Tokens per day** |

Near the limit, credits used also show under **Plan & usage** in the sidebar on
every page.

> **Note:** Until your data plane first reports, usage shows *—* with the reason,
> not 0. A real 0 means it reported and nothing was used.
