OpenChamber

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.
