The mechanical and thermal designs had to change to accommodate this, and that triggered a validation cycle to support a large-scale deployment.&lt;p&gt;&amp;gt; All of these hardware-related changes were challenging because we had to find a solution that fit within the existing resource constraints, with a very small degree of freedom to change and meet a tight schedule.&lt;p&gt;Seems like the time constraints put into the team impacted the overall quality of the model.</text><parent_chain></parent_chain></comment><story><title>How Meta trains large language models at scale</title><url>https://engineering.fb.com/2024/06/12/data-infrastructure/training-large-language-models-at-scale-meta/</url></story>

Our intent was to build and learn from the operational experience.&lt;p&gt;I love how they built two completely insane clusters just to learn. That&amp;#x27;s badass.</text><parent_chain></parent_chain></comment><story><title>How Meta trains large language models at scale</title><url>https://engineering.fb.com/2024/06/12/data-infrastructure/training-large-language-models-at-scale-meta/</url></story>
