@27upon2 harbor is cool def recommend

[viren (维仁) @GovViz]

Labs care significantly about realism of the environment data distribution

So much so that the trend across the prev two quarters for rl env companies was to acquire failed startup repos (which worked for a time but inherently has its flaws)

Looks like many rl env companies are starting to explore new (unorthodox) methods… Very interesting times

finally, a way to pay across borders without screaming into a pillow

[Fin @fin]

We’ve raised 17 million led by @PanteraCapital, with participation from @Sequoia and others.

Fin enables users and businesses to move millions of dollars instantly - whether to other Fin users, directly into bank accounts, or across crypto rails.

If banks and payment products could be rebuilt from the ground up today, they would look like Fin.

@0xrwu @ilmoi @tensor_hq @VECTORDOTFUN congrats!! such an epic team

[Chakra Labs @chakra_ai]

[Browserbase @browserbase]

[se @seyong]

fomo is excited to announce we have raised $17M, led by @benchmark!

[Alexander Fung @alexfung]

@0xnirmal @ben_burtenshaw yup, making sure that dojo envs fit the OpenEnv format first! and then expanding to support open source OpenEnvs on our infra

[will brown @willccbb]

excellent work from @chakra_ai on the Dojo suite, which integrates seamlessly with verifiers + Environments Hub

a full SDK for building real-world web applications as RL environments

very exciting to see the open environment ecosystem growing stronger every day :)

“going to be 10 minutes late”
“omg i lost track of time, will be there in 20”
“wait what we’re meeting up today??”

Encoding human taste into intelligence

[Chakra Labs @chakra_ai]

Today, we're excited to announce GLADOS-1, the first computer-use (CUA) model post-trained using collective, crowd-sourced trajectories.

Post-trained on UI-TARS-7B-SFT, we improved performance of the base model on OSWorld.

[Alexander Fung @alexfung]

it’s rough out there
