-
-- **Follow our coding standards**: Stick to our [development best practices](https://servicenow.github.io/Fast-LLM/development/dev-practices/) to keep the code clean and consistent.
-- **Write tests**: Verify your changes with unit tests for new features or bug fixes.
-- **Test on GPUs and real-world workloads**: Since Fast-LLM is all about training large language models, make sure your changes work smoothly in GPU environments and on typical training setups.
-- **Run benchmarks and performance tests**: Make sure your changes don't slow things down. If there's any impact on performance, provide benchmark results to back it up.
-- **Avoid introducing new issues**: Check that there are no new runtime warnings, type checker errors, linting problems, or unhandled edge cases.
-- **Comment non-trivial code**: Make your code easy to understand for others.
-- **Keep sensitive data out**: Make sure your code or commit messages don't expose private or proprietary information.
-- **Use the [PR template](https://github.com/ServiceNow/Fast-LLM/blob/main/.github/PULL_REQUEST_TEMPLATE.md)**: Complete the checklist to make sure everything is in order before hitting submit.

 ## Overview
 
-Fast-LLM is a new open-source library for training large language models, built on [PyTorch][pytorch] and [Triton][triton]. It is extremely fast, scales to large clusters, supports a wide range of model architectures, and is easy to use. Unlike commercial frameworks like Megatron-LM, which are largely closed off and fragmented across forks, Fast-LLM is fully open-source and encourages community-driven development. Researchers can freely customize and optimize as needed, making it a flexible and hackable alternative that combines the speed of specialized tools with the openness of libraries like [Hugging Face Transformers][transformers].
+Fast-LLM is a cutting-edge open-source library for training large language models with exceptional speed, scalability, and flexibility. Built on [PyTorch][pytorch] and [Triton][triton], Fast-LLM empowers AI teams to push the limits of generative AI, from research to production.
+
+Optimized for training models of all sizes—from small 1B-parameter models to massive clusters with 70B+ parameters—Fast-LLM delivers faster training, lower costs, and seamless scalability. Its fine-tuned kernels, advanced parallelism techniques, and efficient memory management make it the go-to choice for diverse training needs.
+
+As a truly open-source project, Fast-LLM allows full customization and extension without proprietary restrictions. Developed transparently by a community of professionals on GitHub, the library benefits from collaborative innovation, with every change discussed and reviewed in the open to ensure trust and quality. Fast-LLM combines professional-grade tools with unified support for GPT-like architectures, offering the cost efficiency and flexibility that serious AI practitioners demand.
