openai-agents-opsen

Run OpenAI Agents SDK sandboxes on opsen — with machine, model and tool spend on one bill and a budget the runtime enforces mid-run.

pip install openai-agents-opsen

from agents import Runner, RunConfig
from agents.sandbox import SandboxAgent
from openai_agents_opsen import OpsenSandboxClient

agent = SandboxAgent(name="Worker", instructions="...")

result = await Runner.run(
    agent,
    "read the repo and summarise it",
    run_config=RunConfig(
        sandbox={"client": OpsenSandboxClient(
            task_id="code-review",
            budget_usd=2.00,
        )}
    ),
)

What this adds

The SDK ships with Blaxel, Cloudflare, Daytona, E2B, Modal, Runloop and Vercel. Every one of them bills you for the machine and leaves the model bill with a different vendor, on a different invoice, with no shared identifier. Two bills, reconciled by hand, and no answer to "what did that agent cost".

opsen sits in both paths:

session.cost()
# {'total_usd': 0.41, 'compute_usd': 0.02, 'tokens_usd': 0.39,
#  'calls': 34, 'input_tokens': 84120, 'output_tokens': 9310,
#  'task_id': 'code-review'}

budget_usd is a ceiling enforced during the run. An agent that would cross it is refused mid-flight rather than noticed afterwards.

Behaviour worth knowing

Exit codes pass through. The SDK decides whether a step failed from the exit code, so it is returned unchanged rather than flattened.

Commands are quoted, not joined. The SDK hands over argv; " ".join() would turn ("sh", "-c", "exit 3") into a different command that quietly succeeds.

Ports depend on the runtime. getHost-style port exposure works on E2B, works on Modal when the port was declared at sandbox creation, and raises on the local runtime with a message naming the limitation.

Resume carries opsen's own session id. SandboxSessionState.session_id is typed as a UUID and opsen's ids are not, so the state subclasses to keep the real id — the same approach the SDK's own UnixLocalSandboxSessionState takes.

Configuration

Argument	Default	Meaning
`api_key`	`$OPSEN_API_KEY`	From opsen.dev/keys
`task_id`	`"agents-sdk"`	Groups this agent's spend
`budget_usd`	none	Hard ceiling, enforced mid-run
`labels`	`{}`	Arbitrary tags to group spend by
`base_url`	`https://opsen.dev`	For self-hosted deployments

Why a separate package

The SDK maintainers do not take third-party provider implementations into the repo — see PR #3469, where a fully tested NVIDIA OpenShell provider was closed with a preference for "a separate package maintained by the provider team". This is that package.
