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, and everything the estimate cannot attribute — the prompt, tool and MCP schemas, skills)

The breakdown is measured against the same window figure shown above it, so the four segments add up to the used tokens. The split itself 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.
