title: Ultra Reasoning and More Resilient Runtimes
---

> Codex and Claude gain a stronger reasoning mode, with more reliable remote connections, Work startup, and runtime recovery.

## ✨ New

- Codex and Claude Agent now support Ultra reasoning, enabling the runtime's highest reasoning and orchestration mode on supported models.

## 💎 Improvements

- Creating Work now starts its initial run directly on the Server from the submitted goal, reducing client handoff delays and inconsistencies.
- Relay-based remote hosts now reconnect automatically with jittered exponential backoff and restore configured connections after Cradle Server restarts.
- Pull request details now use a compact, persistent tab bar for faster navigation between summary, timeline, checks, and files.

## 🐞 Fixes

- Fixed remote workspace sessions losing the selected provider, model, and reasoning effort during creation.
- Fixed Codex blocked-goal recovery and system-instruction forwarding so automatic recovery and custom instructions apply reliably.
