Gavin Baker Says Open Source AI Faces a Significant Week, Especially U.S. Projects
Investor Gavin Baker posted that there has been significant progress in open source AI this week, particularly with U.S. projects. The NVIDIA Nemotron 3 Ultra is one of the most important recent releases, while Harvey has also made outstanding contributions in reinforcement learning (RL) and fine-tuning.
The Nemotron 3 Ultra is a 550B total parameter (55B active) MoE mixed Mamba-Transformer model, designed for Agentic Reasoning, fully open-sourced and supports efficient inference.
In market mechanisms, developers and companies are buying high-performance open source models and agent tools, while selling high-priced closed-source dependencies; event-driven NVIDIA and Harvey's open source progress is directing funds towards open source AI infrastructure and enterprise-level agent platforms, benefiting from the NVIDIA Nemotron ecosystem and Harvey's legal AI users, while facing pressure from the pricing of purely closed-source cutting-edge models.

NVIDIA has been continuously iterating the Nemotron series, and this time the Nemotron 3 Ultra's mixed architecture continues its evolution from general models to efficient Agentic systems, demonstrating significant efficiency advantages in long context and complex reasoning tasks. Harvey's RL and fine-tuning work further enhances the reliability of vertical domain models.
In terms of capital pathways, NVIDIA is mobilizing developer resources towards its GPU ecosystem through open source weights and training recipes, motivated by the desire to expand open source adoption and drive hardware demand. Strategically, Nemotron is positioned as a mainstay of U.S. open source AI, while providing cost-effective solutions for multi-agent deployments in enterprises.
Similar to the recent trend of open source models rapidly catching up to closed source capabilities, U.S. open source projects are currently transitioning from a parameter competition to efficient Agentic applications, with Nemotron 3 Ultra and Harvey's work accelerating this process.
Essentially, this represents a technological substitution: open source MoE mixed models and RL fine-tuning replace closed source dependencies with cost-effective agent capabilities, aiming to narrow the capability gap and reduce inference costs, driving AI development from closed source high-price monopolies to an open source ecosystem-led reconstruction, accelerating the deployment of enterprise-level agents.

When open source capabilities catch up to closed source, the pricing gap becomes the largest cost leverage.
When mixed architectures meet agent demand, efficient open source surpasses closed frontiers.
In the era of AI infrastructure, breakthroughs in U.S. open source accelerate the ecosystem, with those embracing cost-effectiveness first gaining pricing power among developers.
