Autoresearch as a service: we solve your hardest measurable problems

About hiloop

hiloop helps teams train agents for tasks where general models are not good enough. Give us a task, your current agent or model, and an evaluation. hiloop runs an autoresearch campaign across data, SFT and other post-training methods, continual learning, prompts, tools, harnesses, and systems, then returns the best verified improvement. It runs hosted or in your cloud. We provide the research system around models: persistent memory, full experiment lineage, compute orchestration, and statistical verification. We’re starting with agent and model training, continual learning, and optimization. Reach out to us for early access at founders@hiloop.ai.

    Simple example but I’m excited about autoresearch x robotics. Results from our harness + fable 5 and Sol to the prompt “wave at me”

    It’s quite annoying that people can’t just have a nuanced take.

    It’s quite annoying that people can’t just have a nuanced take. I’m not sure any of these results are Fields medal worthy. That doesn’t take away from the accomplishment but like please stop. ASI is almost surely not here.
