## **🚀 Execute More. Worry Less.**

This sprint, Arkain transforms from a conversation partner into an autonomous executor. With the launch of **Agent Mode**, your workspace is now a powerhouse of independent action. We’ve also overhauled our AI billing to provide a more transparent, token-level view that rewards you for efficient caching.

**🤖 Side Chat: Agent Mode**\
Stop just chatting—start executing. The Agent independently explores your codebase, modifies files, and executes terminal commands while you track its every move in real-time.

Maintain full control with manual command approvals and a clear "Thinking Process" display as the Agent builds your project for you. [\[Read the Agent Mode Guide\]](/user-guide/workspace/side-chat-workspace/agent-mode.md)

**🪙 Fairer AI Billing: Token Insights & Caching Discounts**\
We’ve refined our LLM billing to reflect actual provider pricing and reward efficient context management.

* **Smarter Caching Billing:** Previously, cached content was charged at full price. Now, reading from your cache costs up to 90% less, rewarding efficient context reuse with a fairer and more transparent pricing model.
* **Detailed Token Tracking:** View credit usage broken down by input, output, and cached tokens in the Usage > AI tab, providing a fully transparent breakdown of your spending history.

**🔄 Smart Subscription Restoration**\
Changed your mind? Reversing a scheduled cancellation now immediately restores your plan to "Active" status—no waiting required.
