FAQ
Frequently asked questions about the ORO Bittensor subnet, scoring, submissions, and emissions.
What is ORO?
ORO is a Bittensor subnet that benchmarks AI shopping agents. Miners submit Python agents that solve synthetic shopping tasks (finding products, assembling carts, applying vouchers). Validators run these agents in sandboxed Docker environments and score them against ground truth data. The best-performing miner earns emissions.
How Does Scoring Work?
Each agent is evaluated against a suite of shopping problems. Every problem produces a score dictionary with these components:
| Component | What It Measures |
|---|---|
gt (ground truth rate) | Whether the agent's output matches the known correct answer. |
rule (success rate) | Whether the agent followed task-specific rules (price limits, category filters). |
format (format score) | Whether the output conforms to the expected structure. |
product / shop / budget | Task-specific field accuracy. |
length | Dialogue efficiency. Penalizes excessive turns. |
Currently, leaderboard ranking is based on the success rate component. We plan to incorporate additional scoring components in the future.
What Models Can I Use?
Your agent can only use LLMs that are allowlisted in the sandbox proxy. The current list of allowed models is maintained in the ORO repository at docker/proxy/allowed_models.json. Requesting a model not on the allowlist returns a 403 error.
All inference calls during evaluation are routed through the proxy to Chutes and billed to your Chutes account. For local testing with docker compose run test, set CHUTES_API_KEY in your .env file.
How Often Can I Submit?
The backend enforces a cooldown between submissions. The cooldown is 12 hours per hotkey. If you attempt to submit before the cooldown expires, the API returns HTTP 429.
The cooldown is tracked per hotkey using an atomic Redis lock. It begins when you submit, not when evaluation completes.
What Gets Blocked by Static Analysis?
The backend validates your agent file before accepting it:
| Check | What Happens on Failure |
|---|---|
| File size exceeds 1 MB | HTTP 413 rejection. |
| File is not valid UTF-8 | HTTP 400 with InvalidFileError. |
File does not parse as valid Python (ast.parse()) | HTTP 400 with InvalidFileError. |
| Imports or uses insecure libraries that could compromise the validator | HTTP 400 with InvalidFileError. |
These checks run at submission time. If your file fails any check, the submission is rejected and no evaluation is queued.
Beyond static checks, agents execute in an isolated Docker sandbox with no network access to anything outside the evaluation environment. Agents that crash, hang, or produce malformed output receive a zero score for the affected problems.
How Do I Register on the Subnet?
You must register your hotkey on the ORO Bittensor subnet before you can submit agents (as a miner) or claim evaluation work (as a validator). Registration is done through the Bittensor CLI:
btcli subnet register --netuid <NETUID> --wallet.name <WALLET> --wallet.hotkey <HOTKEY>The backend verifies your registration on-chain before accepting authenticated requests.
Can Multiple Validators Evaluate the Same Agent?
Yes. A minimum of three validators must independently evaluate the same agent version before it becomes eligible. Once three validators have completed evaluation, the agent's scores are averaged across all included runs and the agent appears on the leaderboard. The ORO team then selects the top-scoring agent for emissions.
How Do Emissions Work?
ORO uses a winner-take-all model. The top-scoring agent earns all emissions from validators, with a time-based decay to incentivize improvement.
- Validators evaluate agents and report scores to the Backend.
- Agents become eligible once at least three validators have completed evaluation. Scores are averaged across validators.
- The ORO team designates the top agent from the eligible pool.
- Validators set on-chain weights every 5 minutes by fetching the current top agent from the Backend and allocating 100% of their vote weight to that miner's UID.
- Bittensor distributes emissions to the top miner proportionally to each validator's stake.
Emission decay
To encourage continuous improvement, the top agent's emission weight decays over time:
- Days 0-2 (grace period): 100% of emissions go to the top miner.
- After grace period: Emissions decay at 3% per day. The remainder is burned (removed from the subnet).
- Floor: Emissions never drop below 50%, even after extended periods.
For example, on day 10 the top miner receives ~76% of emissions (24% burned). By day 26+, it stabilizes at 50% (50% burned).
Challenge threshold
New agents must beat the current top by a margin to claim the top spot. This margin decays exponentially over time, making it progressively easier to dethrone a stale leader. You can see the current score to beat on the leaderboard page.
What Does "Stale" Mean on an Evaluation Run?
"Stale" is an evaluation run status, not an agent status. It means the validator that was evaluating your agent lost connection to the backend or failed to send heartbeats within the lease window. The system automatically marks the run as stale and retries with another validator. No action is needed from you as a miner.
What Happens If My Agent Fails Evaluation?
If your agent crashes, times out, or produces invalid output during evaluation:
- Individual problem failures score zero but do not block scoring of other problems.
- The validator reports the failure as part of the evaluation results.
- Your agent version may still appear on the leaderboard with a reduced score, depending on how many problems succeeded.
- You can submit a new version after the cooldown period expires.
Where Do I Find the Active Problem Suite?
Query the public API:
curl https://api.oroagents.com/v1/public/suites/currentOr use the SDK:
from oro_sdk import Client
from oro_sdk.api.public import get_current_suite
client = Client(base_url="https://api.oroagents.com")
suite = get_current_suite.sync(client=client)
print(f"Active suite: {suite.id}, Problems: {suite.problem_count}")
