Package Exports

opencode-token-tracker
opencode-token-tracker/dist/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (opencode-token-tracker) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Installation

Add to your OpenCode config file (~/.config/opencode/opencode.json):

{
  "$schema": "https://opencode.ai/config.json",
  "plugin": ["opencode-token-tracker"]
}

Usage

Toast Notifications

Once installed, you'll see Toast notifications after each AI response:

12.5K tokens
$0.023 | Session: $0.156

When a session becomes idle, you'll see a summary:

Session: 45.2K tokens
$0.156 | 8 msgs | 5min

CLI Statistics

Query your token usage from the command line:

# All-time summary
opencode-tokens

# Today's usage
opencode-tokens today

# This week's usage with model breakdown
opencode-tokens week --by model

# This month with all breakdowns
opencode-tokens month --by all

# Day-by-day breakdown
opencode-tokens --by daily

Example output:

Log Files

Token usage is logged to:

~/.config/opencode/logs/token-tracker/tokens.jsonl

Each line is a JSON object:

{
  "type": "tokens",
  "sessionId": "ses_xxx",
  "messageId": "msg_xxx",
  "agent": "build",
  "model": "claude-opus-4.5",
  "provider": "github-copilot",
  "input": 1500,
  "output": 350,
  "reasoning": 0,
  "cacheRead": 5000,
  "cacheWrite": 0,
  "cost": 0.0234,
  "_ts": 1234567890123
}

Supported Models

Provider	Models
Anthropic	Claude Opus 4.5, Sonnet 4/4.5, Haiku 4/4.5
OpenAI	GPT-5.x, GPT-4.x, o1, o3
DeepSeek	deepseek-chat, deepseek-reasoner
Google	Gemini 2.x, 3.x

Unknown models use a default pricing estimate.

Configuration

Create a config file at ~/.config/opencode/token-tracker.json:

{
  "providers": {
    "github-copilot": { "input": 0, "output": 0 }
  },
  "models": {
    "my-custom-model": { "input": 1, "output": 2 }
  },
  "toast": {
    "enabled": true,
    "duration": 3000,
    "showOnIdle": true
  }
}

Pricing Override

Pricing is resolved in this order (first match wins):

Provider-level - Override all models for a provider
User model config - Custom model pricing in config file
Built-in pricing - Default pricing table
Fallback - $1/M input, $4/M output

Example: Free providers

If you're using GitHub Copilot or other subscription-based services, set their cost to $0:

{
  "providers": {
    "github-copilot": { "input": 0, "output": 0 },
    "cursor": { "input": 0, "output": 0 }
  }
}

Example: Custom model pricing

Override or add pricing for specific models:

{
  "models": {
    "claude-opus-4.5": { "input": 12, "output": 60, "cacheRead": 1.2 },
    "my-local-model": { "input": 0, "output": 0 }
  }
}

Toast Settings

Option	Type	Default	Description
`enabled`	boolean	`true`	Show toast notifications
`duration`	number	`3000`	Toast display duration (ms)
`showOnIdle`	boolean	`true`	Show session summary on idle
