# Context

Every model can only hold so much of a conversation at once — its context. OpenChamber shows how full that is, so you can tell when a session is getting close to the limit and a reply might start dropping older detail.

## The quick indicator

While you chat, a small gauge shows the percentage of context used. It changes color as you fill up:

- green — plenty of room
- yellow — getting full (around three-quarters)
- red — nearly full

Hover it (or tap it on mobile) to see exact token counts.

## The full context panel

Open the **Context** tab in the right sidebar for a fuller picture of the current session:

- the model in use and when the session started
- total tokens against the model's limit
- message and cost totals
- a breakdown of the last reply's tokens
- a rough split of what's taking up context (your messages, the agent's, tool output)

The breakdown is an estimate, not an exact count — use it to spot what's filling the window, not for billing.

## What to do when it's full

Start a fresh session for a new task instead of letting one session grow forever. A shorter context is faster and keeps the model focused.
