# March 21 - Smarter, Faster, Stronger Agents

### Agent Upgrades

* **Smarter Editing**: The agent can now **edit existing notebook cells**, not just create new ones.
* **On-the-Fly Problem Solving**: Rather than planning everything upfront, the agent now **figures things out as it goes**—making it more adaptive and efficient.
* **Full Notebook Awareness**: The agent receives the **entire notebook as context**, improving accuracy and coherence.
* **Citations**: The agent can now **generate citations** when appropriate.

### Chat History

* You can now **open previous chat histories** to review or continue past conversations.

### Performance Improvements

* **Model upgrade**: We've moved from o3-mini to **GPT-4o** — about **10x faster** on agent prompts. There's a small quality tradeoff, but the speed boost is worth it.
* **Websocket Resilience**: If you're idle for a while, **websocket connections will now automatically reconnect**.
* Behind the scenes server tuning to ensure less timeouts for server key users. 

### Monthly Limits (for OS Users)

* Open Source users now have **50 completions** and **5000 autocompletes** per month.
* These limits **reset at the start of each month**.

### Bug Fixes

* Markdown backticks (\`\`\`) now render in **purple font**, as expected.
* The **variable dropdown scrolls** properly again—no more cut-off options.
