Today, we are announcing our Series B funding round, valuing the company at more than $1B.
This round accelerates our next-gen Trinity models across diverse infrastructure, expands our work with the DOE and national labs on Genesis-Science-1, and enables us to build the platform aluate, deploy, and operate open models in production.
We are grateful to our team, partners, open-source community, and investors.
Led by @Vista_Equity, Cambium Capital, and @emergencecap, with participation from AI10 Ventures, @Hitachi, IAG, @M12vc, @p7ventures, and @Wipro.

If you weren't able to make Flower AI Day last month, the full recording of our CTO @latkins' fireside chat is now up on the @flwrlabs channel.
A few of the topics covered:
• Pre-training the 400B Trinity MoE on 2,000 B300s
• Debugging router and expert collapse mid-run
• Significantly dropping training costs using synthetic data and Blackwell kernels
• Post-training across diverse agent harnesses and continual pre-training

Our portfolio company @arcee_ai released a tool called NAC to help agents work through long engineering tasks.
The team built it for work they needed to do themselves, including running experiments and working on their infrastructure. One part of how it works seems pretty relevant to anyone spending time with agents.
As an agent works on a task, it can build up a lot of history. Some of that is important to whatever happens next. Plenty of it is just the mess of getting there.
NAC lets the immediate working context be temporary while keeping a record of the progress so far. The next part of the work can pick up from that record.
If you've ever handed a project to another person, you’ve experienced this same problem first-hand. You know they need enough information to get started, but sending them everything at once can be a lot to manage.
I'm curious how this develops as we give agents longer and longer assignments.

Open weights are ultimately about choice.
Which model you use. Where it runs. How you customize it. How much control you keep.

Nathan has worked his ass off in recent months to get this off the ground, and I'm so excited he can finally show it off! Congrats, and the community is better off with you and @trillium_labs in it!
Today we're unveiling Trillium Labs @trillium_labs, a new non-profit to foster the open science of frontier AI. We're building open post-training recipes and will expand into open infra to study RSI, reward-hacking, multi-agent systems, and whatever comes next.
We're built ange that you need more eyes to solve hard technical problems. We have faith in the scientific methods and communities that humanity has built, and worry that AI is becoming too closed to utilize them.
Trilliums are wildflowers that bloom briefly in the spring, before the forest canopies fill out. Though they are small, they lay the foundation for the cycles of growth and nourishment through the rest of the year. At Trillium Labs, the recipes will be the slow nutrients for the seasons and the model releases will be the blooms. Building an institution dedicated to this is needed because, much as nature’s trilliums are slow to expand and grow, the open-ecosystem needs time and dedicated resources to catch up.
I co-founded with with a long-time friend and collaborator Tom Zick (@thesezickbeats). We're hiring (full time + student collabs/interns), we're fundraising, and we're looking for compute. Please get in touch if you're interested in helping out. Offices based in the Bay Area and Cambridge MA, remote okay.
I’m in the Bay Area until for The Curve and COLM to connect with people who are interested. We’re thankful to have initial support from Halcyon Futures and Schmidt Sciences with more funding en route to enable our ambitions of scaling. Our advisors @Thom_Wolf, @HannaHajishirzi, @gneubig and @ctnzr have been instrumental to building the ecosystem that exists today, and I’m stoked to get to keep working with them.
