The open-weights reasoning model that shook the industry — frontier performance at a fraction of the cost.
DeepSeek-R1 proved that frontier-level reasoning could be trained for a fraction of Western budgets and released under an MIT license. Its launch in January 2025 wiped hundreds of billions off US tech valuations in a day and triggered a global wave of open reasoning models. It remains a cornerstone of the open-weights ecosystem.
