## Core Upgrades

This release completes a **full underlying architecture overhaul**, reinforcing stability at the service layer and significantly improving request success rates and service reliability in high-concurrency scenarios, providing a more stable model invocation experience.

## Feature Updates

2. **API key quota supports long-term validity** — Added a long-term validity option for API key quotas, eliminating the need for periodic renewals to support stable long-term use.
3. **Pass-Through mode** — Supports native protocol pass-through for third-party models, enabling compatibility with more third-party service call methods.

### Important Notes
