 ## Support Lambda
 
-[Lambda](https://github.com/KeisukeMiyamoto1324/lambda) is a project I am developing as a student to build small Japanese language models from scratch. The datasets, source code, and model weights are publicly available.
+Lambda is an open-source project for building small Japanese language models from scratch. As a student, I have funded this project with income from my part-time job, but the growing training costs are becoming difficult to cover.
 
-Training language models is very expensive, and I have funded the project with income from my part-time job. As the models grow, the cost is becoming too high for me to maintain the current development pace.
+Your support helps cover GPU costs and develop larger models. Thank you for helping Lambda continue to grow.
 
-You can support Lambda in two ways: use the Vast.ai referral link when purchasing GPU credits or make a donation through Ko-fi. Thank you for helping Lambda continue to grow.
