Sundar Pichai Backs Jensen Huang’s Open-Weight AI Push as OpenAI Joins Letter, Anthropic and Amazon Remain Notably Absent

Alphabet Inc. (NASDAQ:GOOG) (NASDAQ:GOOGL) CEO Sundar Pichai has endorsed Nvidia Corp (NASDAQ:NVDA) CEO Jensen Huang’s push for open-weight AI models as OpenAI joins the industry letter after initially sitting out, while Anthropic and Amazon.com, Inc. (NASDAQ:AMZN) continue to remain absent.

Google, OpenAI Rally Behind Open-Weight AI Initiative

Last week, Pichai threw Google’s support behind the growing industry push for open-weight artificial intelligence models, joining Huang’s public campaign against potential U.S. restrictions on downloadable AI models.

Pichai said, “Very happy to support this on behalf of Google.”

He added that Google has “long benefited from open source,” pointing to the company’s contributions through its Gemma family of open-weight models developed by Google DeepMind.

Very happy to support this on behalf of Google. We have long benefited from open source, are big contributors to open source and in fact have consistently made open weights models with Gemma available from @GoogleDeepMind @demishassabis . Onwards! https://t.co/kL0kPjyl8k

He said DeepMind has consistently supported open science through projects including JAX, Transformers, AlphaFold and Gemma, adding that Gemma models have been downloaded more than 300 million times.

Microsoft, Meta, Musk and AMD Join Growing Coalition

Earlier, Microsoft Corp (NASDAQ:MSFT) CEO Satya Nadella described open-weight models as “essential to a healthy AI ecosystem,” saying they strengthen American competitiveness while protecting national security.

Meta Platforms, Inc. (NASDAQ:META) CEO Mark Zuckerberg echoed that view, writing, “Open source is a positive and important force for both empowering people and preventing centralization.”

Tesla Inc. (NASDAQ:TSLA) CEO Elon Musk later shared Zuckerberg’s post, commenting, “Overwhelming support for open source.”

AMD also backed the initiative, saying open standards, interoperability and customer choice remain central to building a strong AI ecosystem.

Open has always been at the heart of how we build at AMD.

That’s why we’re joining @Microsoft and others in signing an open letter supporting open-weight AI models. A strong AI ecosystem depends on open standards, interoperability and choice across software, systems and… pic.twitter.com/XdQzOkDO6D
