“Thanks to https://tinker-docs.thinkingmachines.ai/tinker/ for the training infra.”
“Some links I found but I can't vouch for them:”
“I used it last week for an application using a small model just as an experiment. It all went very well.”
“I found it easier and cheaper to just build from scratch.”
“Thinky's main commercial product AFAIK is Tinker [0] - companies pay them to host their fine-tuning workloads”
“the stack of Tinker, Prime-RL & Runpod - all of which I know well”
“even with a finetuning-as-a-serice like Tinker (the one from Thinking Machines) which is pretty cheap, the economics didn't work out that well.”
“Seems like an open source tinker”
“It’s one of the smoother experiences we’ve had running large scale RL workflows.”
