Tinker Command Center
Your $200 Opus session didn't have to happen. Tinker shows you exactly where every token goes — before the bill arrives.
The Problem
You switched to Claude API because Anthropic did the right thing. Respect. But now you're running Opus through OpenClaw and a single deep conversation burns $20+ in tokens with zero warning. You check your dashboard three days later and wonder what happened.
That's not a billing problem. That's a visibility problem.
What Tinker Does
Tinker is a real-time command center that sits on top of your OpenClaw gateway. It shows you what's filling your context window, what each response costs, and where your budget stands — live, as it happens.
🗺️ Context Treemap
Interactive squarified treemap of your context window. See exactly what takes space: system prompt sections, conversation history, tool results. Drill down from categories → messages → raw text. When you wonder "why is my context 180K tokens?" — this tells you in one glance.
📊 Response Treemap
Same visualization for model output. How much is text, how much is thinking, how much is tool calls? Per LLM call within a run, so you see the real cost of that 8-step tool loop.
💰 Live Cost Tracking
Per-provider token usage. Daily and monthly estimates. The 5-hour Claude rate-limit window with countdown timer. You'll never hit a rate limit by surprise again.
⚠️ Budget Alerts
Set a monthly limit. Get warned at 70%, 90%, and 100%. No more "I'll check later" — later is too late with Opus.
🔄 Multi-Call Run View
When your agent loops through tools (search → read → edit → test → commit), each call's context and cost is broken out individually. You'll see which tool calls are token hogs and which are cheap.
💬 Full Chat Interface
Not just a dashboard — it's a complete webchat with session switching, tool call inspection (expand any tool inline), and real-time streaming. Use it as your daily driver or just for monitoring.
Pricing Reference
These are the API costs Tinker tracks:
| Model | Input (per 1M) | Output (per 1M) | Watch out? |
|---|
| Claude Opus 4 / 4.5 | $15.00 | $75.00 | ⚠️ Yes. One deep session = $20+ |
| Claude Sonnet 4 / 3.5 | $3.00 | $15.00 | Sweet spot |
| Claude Haiku 3.5 | $0.80 | $4.00 | Background tasks |
| Gemini 3 Pro | $1.25 | $5.00 | Great failover |
| Gemini 2 Flash | $0.10 | $0.40 | Near-free |

Why Now?
Anthropic refused the Pentagon contract. Respect. Claude overtook ChatGPT in the App Store this weekend. People are migrating to Claude API in droves.
But Claude API through OpenClaw is unmetered. There's no $20/month cap. Opus input costs $15 per million tokens, output costs $75. A single agent session with tools can easily consume 200K+ tokens. Do the math.
If you're switching to Claude API because you believe in Anthropic's mission — you should also know what you're spending. That's not about being cheap. That's about being informed.
Tinker makes you informed.
