Salesforce, Microsoft and Snowflake join Nvidia’s Open Secure AI Alliance, expanding a coalition promoting open-source and open-weight artificial intelligence models as standard industry infrastructure. The group frames open architectures as critical for maintaining competitive markets and enabling third-party developers to build and modify models independently.

The expansion coincides with Nvidia CEO Jensen Huang traveling to Washington, where he will meet bipartisan lawmakers including Sen. Mark Warner. Huang will argue that protecting open models is necessary to improve cybersecurity and preserve United States technology dominance.

Many more signatories have joined the NVIDIA–Microsoft letter on open-weight AI models, including AMD. It shows a united front to Washington, D.C. in support of open-weight AI models. Politicians and regulators should listen to industry.

Indeed Anthropic and any other cosplay fear theater types: Read The Room. Open Source AI. Oh by the way, 98% of the software that delivered this posting is open source.

@jesseproudman

This is our foundation thesis for @AskVenice. A world in which a handful of tech companies become arbiters for acceptable speech is not an acceptable world.

@edzitron

Anthropic also wouldn’t exist without Google and Amazon building all its infrastructure in addition to funding it much like OpenAI wouldn’t without Microsoft doing the same. All of this kayfabe around these being “startups” is hilarious

@deanwball

The most important and illuminating dichotomy in AI policy right now is between those who believe the most significant event of last week was the open-source letter and those who believe it was the Hugging Face incident.

@hesamation

BREAKING: none of them signed

Anthropic's campaign for tighter restrictions on Chinese AI models has left it increasingly isolated from much of Silicon Valley. Full story:
