@whitecircle open-sourced Halo today - their in-house training framework.

Halo delivers 2.3–2.8× the throughput of stock TRL at lower peak memory. It also scales past fine-tuning to agentic and asynchronous RL, with SGLang handling rollout generation.

@chrisellisdc @thatch_ai @thegp @IndexVentures @generalcatalyst @a16z Amazing.

[Chris Ellis @chrisellisdc]

Today, we're announcing @thatch_ai raised a $108M Series C at a $1B valuation from @thegp, @IndexVentures, @generalcatalyst, @a16z.

The idea we're betting on: healthcare serves whoever controls the dollar. For 80 years that's been the employer. We think it should be you.

Employers typically choose one health plan for everyone. We think there's a better model: give people a health budget and let them choose the insurance and care that fits their life. That is the idea behind Thatch.

ARR has grown nearly 7x in the last twelve months, and more than 5,000 employers now use Thatch. None of this happens without our team, or without the employers who believe that their people know what their families need better than they ever could.

We're building a healthcare system people love by changing how we fund it.

We built a model ranking the current @ycombinator batch ahead of demo day.

@ypatil125 & the @appliedcompute-team just shipped AC2 to the public.

Over the last six months, AC2 has powered their Applied AI team’s work for Microsoft, NVIDIA, Cognition, Harvey, DoorDash, and others.

Now, they're empowering every AI team with their own model factory 👏

As investors in @FireworksAI_HQ , we've been watching their data on open vs. closed models - and it's telling a specialist story, not a generalist one.

Increasingly, the routing layer is the product, not the model. Full breakdown → https://t.co/1Gj9TqR4Ze

@NStoronsky and James Gibson on how @Revolut builds @ “The Engine of Ambition” event with the @audif1_ team.

"Never settle" is an operating standard people are actually held to.

Strip it back and @Revolut 's edge is people holding an unusually high bar.
