 ## 特别感谢

+开发维护 ChatLab 的过程消耗了大量 Token，最开始是我自费的。直到 OpenAI 通过开源计划，突然给我发放了 6 个月的 ChatGPT Pro 20x。
+
+这是 ChatLab 至今获得的唯一一项外部奖励，它为项目带来了非常实际的帮助！更充足的使用额度大幅缓解了开发过程中的 Token 焦虑，也让 ChatLab 的迭代速度有了明显提升。

+感谢 OpenAI 对开源社区的投入，以及对 ChatLab 的认可与支持。🙏

 ## Special Thanks
 
+### OpenAI
+
+Developing and maintaining ChatLab consumes a large number of tokens, and I initially covered those costs myself. That changed when OpenAI unexpectedly granted me six months of ChatGPT Pro 20x through its open-source program.
+
+This remains the only external award ChatLab has received, and it has made a very real difference to the project! The increased usage allowance greatly reduced token anxiety during development and noticeably accelerated ChatLab's iteration.
+
+Thank you, OpenAI, for investing in the open-source community and for recognizing and supporting ChatLab. 🙏

 ### Leo Oliveira ([@13dev](https://github.com/13dev))
 
 In early 2026, we decided to move ChatLab from a personal GitHub account to an organization — a natural step as the community grew. There was just one problem: the "ChatLab" organization name had been registered years earlier by a developer in Madeira, Portugal named Leo Oliveira. His project had been inactive for over five years.
