Simo is the System 1.5 judgment model from Temprl Labs. Ask typed questions about text, screenshots, or video and get calibrated probabilities and the values needed to act, in milliseconds.
Hey Product Hunt! 👋 I’m Sri Santh, the founder of Temprl Labs. I’m 23 and building from Madurai, India.
Simo started with a practical question: can a model make a decision and return the details needed to execute it in the same call?
A support agent needs to choose “issue a refund,” then supply the correct amount and order ID. Simo brings those together: decisions, confidence scores and typed values, with text and visual inputs.
We call this System 1.5: fast judgment, plus the details needed to act.
Simo builds on an existing model, with our custom algorithm and implementation for combining decisions with Fill and Extract.
We’ve put together demos covering invoice approval, logistics and support agents. These are early internal evaluations.
I’d love to hear from developers building agents or automation: where does your workflow need both a judgment and extracted values?
Take a look at the demos, ask me about the implementation, or share a tricky example you’d want Simo to handle. I’m here to answer questions and learn what we should improve next.
