Excited to announce TrainLoop! We're the first end-to-end solution focused on fine-tuning for reasoning models. Stuck in prompt hell or dealing with bad model decisions? We specialize in verifiable domains: codegen, RAG, and compliance!

@YinjieW2024 @rronak_ @MengdiWang10 I didn’t see the LoRA note in the readme! I don’t remember exact config, because I tried this when you launched it. I do remember I did try Lora and bumping up the lr. Iirc I used opsd (didn’t try binary rl) I’ll give it another shot!

Which RL server and config are you using? Our evaluation setting demonstrates Qwen3-4B can learn “not talking like AI” in about 36 conversation sessions. If you are using tinker, “not learning” may happen for small models because they are using LORA, like we pointed out in readme.

This paper is almost too good that I didn't want to share it Ignore the OpenClaw clickbait, OPD + RL on real agentic tasks with significant results is very exciting, and moves us away from needing verifiable rewards Authors: @YinjieW2024 Xuyang Chen, Xialong Jin, @MengdiWang10 @LingYang_PU

3 months ago we started building an IDE for the AI agents era Today we’re introducing Superset: an open source app for running any agents in parallel. And today we launched Chat 😉, enabling us to build way more superpowers into how users interact with agents (@ context, link Linear tickets, / commands, etc)

Like clockwork

Hardest part of running an ai company is deciding what to name the next version

@LessCodeMoreAI Congrats!

I’ve joined Anthropic as an engineer in the Applied AI team. i'm going to start sharing some of the latest work our team is doing. follow me if you're into building on claude's SDKs/APIs. let's get you claude pilled.

@a16z Marc Andreessen had hair?!?!?

It's time to build.

@creatine_cycle ….women?

so much attention is given to sundresses and not enough attention is given to whatever the hell these are. it's summer in australia and every day i walk outside i am just oneshotted by these. concerning

@avimakesrobots Will superset 1.0 prevent Claude from dropping our prod tables (again?)

Superset 1.0 is gonna be fire

just wrote out my 2025 highlights and, wow, it'll be a hard one to beat: work: > crushed it at yoodli jan - june (closed some massive logos im still super proud of) > started scaling the team with AI + Agents > decided to quit and build as solo founder > built a new product from scratch and closed first customers @ onepager > got my first office > shipped more than i have in my entire life personally: > ran my first triathalon > started playing soccer consistently again > traveled to: norway, argentina, switzerland, guatemala, skied chamonix france and valle nevado chile, and spent a month in india > spent more time w best friends than i have in years > made new friends that i love and cherish > healthier than 2024 by a mile but most importantly, i turned 26 and realized that every dream 18 yr old sharan had, i had accomplished ofc have a ton of new dreams, but man what an amazing feeling... and can only get better from here! thanks to the many of you on here who have been part of this year, endlessly grateful!

@skeptrune Real. Went on a week long ski trip to Colorado and only skied 1 day. Tahoe stole the snow😤

i went up to Tahoe to ski this weekend because it's my last weekend off of work and completely failed to actually ski. very embarrassingly i somehow did not actually buy an ikon pass this year despite thinking I did. so the first day we got to the resort and I went to print my ikon pass and they were like, sir, you don't actually have one. then we wound up deciding not to ski at all that day because there were very few runs open due to wind conditions and snow. it seemed like conditions were getting better that night, so I didn't bother to put chains on and parked the car. that was a mistake because this morning, whenever I woke up and tried to pull the car out, it was impossible. there wasn't enough traction. ultimately I had to struggle bus in the snow to get chains on this morning. by the time we were done, it was already 11, and once again, most of the terrain was closed today, so we didn't bother to ski and just headed back. can't wait to be back in office tomorrow!

@sharanjhangiani Por que no los dos?

crazy how all it takes is a ski day to remember that having the most optimal claude code setup actually doesn’t matter that much truly, crazy

@laurenfrailey1 Montezuma’s revenge but for Bali

@mlpierce22 horrific whole fam was in shambles throwing up all day

got bali belly & had to miss NYE celebrations this year, so here’s last year in sydney :)

@danifesto Lfg this looks sick

We’re building a soul computer. Not a copy of you. Something that grows by knowing you. Shaped by your life, yet distinctly its own. Pickle OS is where that soul is raised. Pickle 1 is how it sees the world. Now live at pickle.com

@avimakesrobots Lfggg

number 1 here we come

@juliasteinberg @D_R_Farrell the people want you

If we could benchmax this that would be really helpful. Thanks

100% on AIME is funny. Why even put it
