[Anthropic Team Member Mocks Tech Giants' Embrace of Open Source: Looking Forward to Microsoft Open-Sourcing Windows and NVIDIA Open-Sourcing CUDA] Odaily Planet Daily News – Anthropic team member Julian Schrittwieser recently posted on social media, humorously commenting on the shift in some tech giants' attitudes toward 'open source' in recent years. He expressed anticipation for NVIDIA and Microsoft to further open up their core technologies, stating: 'It's great to see Jensen Huang becoming a supporter of open source. Looking forward to the open-source release of CUDA and GPU drivers; also looking forward to Satya Nadella supporting open source, hoping to see Windows and Microsoft Office open-sourced in the future.' Julian Schrittwieser also addressed external speculation about his opposition to open weight models, clarifying that such interpretations are inaccurate. He believes that open models can actually play a significant role in many scenarios. However, Schrittwieser pointed out that it is intriguing how some companies that have long been cautious or even opposed to open source are now rapidly shifting toward supporting open ecosystems. In recent years, as competition in artificial intelligence has intensified, open-source models, open weights, and developer ecosystems have become critical areas of competition in the tech industry. Companies like NVIDIA and Microsoft have also repeatedly emphasized their support for open ecosystems. However, there is still debate within the industry about the definition of 'open'—some companies open up model interfaces, toolchains, or ecosystems, while keeping core commercial assets closed-source. Julian Schrittwieser's remarks have sparked discussions, with the focus centered on whether tech giants' push for 'selective open source' represents true openness or a new strategy for ecosystem competition.
