Reason Machines examples

Run the Reason agent through the Reason Machines API.

Installation

Install the Reason CLI:

curl -LsSf https://reasonmachines.com/install.sh | bash

Install the Pier adapter with Python 3.12+:

pip install --upgrade https://github.com/reason-machines/examples/releases/download/latest/reason_machines_pier.tar.gz

Example: running DeepSWE

Download the DeepSWE tasks and get your REASON_API_KEY from the Reason Machines dashboard.

export REASON_API_KEY="<your-reason-api-key>"
pier run --path deep-swe/tasks \
  --agent-import-path reasonmachines_pier:ReasonAgent \
  --model openai/gpt-5.6-luna

--agent-import-path reasonmachines_pier:ReasonAgent loads the Reason adapter. Everything else uses standard Pier options.
