Reason Harbor adapter
Run Reason as an agent in Harbor. Harbor starts the task container and grades the result. The adapter installs the published Reason CLI in that container, checks its checksum, and starts it as a worker; the agent runs as a normal Reason Session. Your API key stays on your machine; the container only receives a one-use enrollment ticket.
Install
uv pip install reason-machines-harbor
This installs Harbor 0.22.0. For cloud environments, add the matching Harbor
extra, for example uv pip install "harbor[modal]==0.22.0".
Run
Get a Reason API key with
run, sessions:read, deployment:read, devices:read, devices:write,
devices:use and org:write, and enable the model under
Models.
export REASON_API_KEY="YOUR_REASON_API_KEY"
DOCKER_DEFAULT_PLATFORM=linux/amd64 harbor run \
--dataset datacurve/deep-swe-1-1 --n-tasks 1 \
--agent reasonmachines_harbor:ReasonAgent \
--model openai/gpt-6-luna \
--ak reasoning_effort=xhigh \
--allow-agent-host api.reasonmachines.com \
--allow-agent-host relay.reasonmachines.com \
--env reasonmachines_harbor.environment:ReasonDockerEnvironment
The worker connects out to the Reason API and relay, so both
--allow-agent-host flags are required, even for offline tasks.
Agent kwarg (--ak) |
Default | Meaning |
|---|---|---|
reasoning_effort |
medium |
minimal, low, medium, high, xhigh or max |
mode |
ephemeral |
ephemeral: a new single-use workspace per trial, with memory and skills on. standard: your own workspace |
runtime_profile |
runtime/reason-agent-1.2 in ephemeral mode; the server default in standard mode |
A harness listed by GET /v3/deployment. The default is the frozen Reason Agent 1.2 release: it never changes, and its trials install the CLI and agent tools it pins (CLI 0.2.151). Name an earlier release to rerun it, for example runtime/reason-v7-2026-10; runtime/reason-c2-tools-v7 runs the deployment's current default instead |
Ephemeral mode needs an owner or admin key of a workspace with paid model
access. To bill the model to your own provider account, connect its API key
under Models and pass the
model as byok:<provider>:<model>, for example byok:openai:gpt-6-luna.
To run the full benchmarks and reproduce our results, see reason-machines/benchmark.
