Four labs release frontier-scale open-weight AI models in three days

By PulseAugur Editorial · [1 sources] ·

In a rapid succession of releases, four distinct research labs have unveiled frontier-scale open-weight models. Meta released an 816 billion parameter model, followed by DeepSeek with a 763 billion parameter model developed in conjunction with MIT. StepFun contributed a 600 billion parameter model, and Reflection released a 501 billion parameter model under the Apache 2.0 license. This surge in open-weight models shifts the focus from performance benchmarks to the implications of licensing terms. AI

    Four labs released frontier-scale open weights in three days: Meta 816B, DeepSeek 763B (MIT), StepFun 600B, Reflection 501B (Apache 2.0). The open frontier is now a licence question as much as a benchmark one. https:// artifocial.com/blog/ai-news-20 26-oct-12-18 # AI # MachineLea…
