Task-Pins for the work you already own

Don't pick a model. Pin a specialist on your data. Run a bounded warm route. Keep the receipt.

Bay Run's public front door starts with coprocessor for one bounded Guard-first composition, keeps run_pin as the direct canonical-Pin alias, and uses solve_task only as fallback. All four canonical Pins are provisional routes. Each response states its evidence, route, and receipt limits.

Warm-route latency is measured in-process/post-warm, excludes network/TLS, and is not an SLA. Cold starts stay visible; fewer than 30 labels or incomplete proof stays private and creates no card, badge, or author claim.

Run a provisional Pin Read the agent contract

Start with the bounded coprocessor; use a direct canonical-Pin alias when the Pin is already known, and the fallback only when none fits. Advanced compatibility remains subordinate.

Default/public contract

Three focused MCP tools, led by a bounded coprocessor.

All four code-owned canonical Pins remain provisional routes, not measured winners or production-fitness claims.

`coprocessor`

Run the canonical Guard first and continue only after SAFE; Bay Run never generates or executes tools.

`run_pin`

Use the direct alias when one of the four exact canonical Pin IDs and its input shape are already known.

`solve_task`

Use the open-ended fallback only when none of the four provisional Pins fits.

The Task-Pins loop

Choose. Finish faster. Cover yourself.

Keep the first session focused on held-out evidence. Bay Run says when the field is too small or too weak to support a winner or public Pin.

Choose

Run a provisional canonical Pin when one of the four exact task contracts fits.

Finish faster

Use the open-ended fallback only when no canonical Pin matches. The response reports the route and latency actually received.

Cover yourself

Keep the receipt: model, measured F1 and interval, price ceiling, and no training by default. Weak or no_specialists outcomes never become public claims.

Clear system boundary

Catalog and execution are different jobs.

The two products work together without asking an agent to understand the internal architecture.

Hugging Bay

Catalog and provenance layer

Hugging Bay catalogs specialist artifacts, mirrors eligible models, and records provenance and verification evidence.

Browse Hugging Bay when you need artifact discovery or provenance detail.

Bay Run

Decision and execution layer

Bay Run receives a task and constraints, selects a qualifying route, and returns the result with independently checkable receipt metadata.

Use the task contract when you need an outcome, not a list of models.

Subordinate advanced compatibility lab

Describe the task. Paste labels. Read the field honestly.

This form sends the canonical task_description + examples shape to /v1/bakeoff. An underfilled field returns no_specialists; a weak field makes no best-model, badge, or author-claim offer. Anonymous mini bake-offs stay private; a public card requires at least 30 labels, held-out intervals, measured p95, a served-weight SHA-256, one measured frontier winner, and an authenticated Ed25519 evidence record.

Bounded by design

A useful first result without setup.

The bake-off is free during launch, accepts at most ten labeled examples, and has a durable per-principal daily cap before model work begins.

Curated candidates only — then warm-family intersectedA model is scored only when it is both resident and compatible with the detected task family.
Private until evidence qualifiesRequesting public=true creates a share page only after the separate measurement and receipt-authenticity gates pass.
Exact next call after a real winA completed field carries a ready-to-use request; a weak or underfilled field makes no best-model claim.
Receipt limits are explicitAn Ed25519 proof can authenticate the recorded request, candidate set, metrics, warm/cold latency, and served Hugging Bay weight hash; HMAC is a MAC, not a proof. Even a complete proof does not establish answer truth, model quality, model-weight identity, or production fitness.

Production controls appear after a winner. Read data handling before sending labels

Labeled examples

Use 3–10 lines: input => expected string. For retrieval or reranking, use query || relevant document.

Keep this labeled mini result private. Public sharing requires the complete measurement and receipt-authenticity gates.

Structured response

Field status, scorecard, and evidence

The response is rendered as data so an agent or developer can inspect the contract directly. No model-quality or performance number is asserted until the live scorecard supplies evidence. Returned model scores are uncalibrated outputs, not probabilities of correctness.

{
  "status": "waiting",
  "next": "Describe a task and submit the form"
}

Production

Recurring task operations

Keep the route that works.

Authenticate with a durable bearer, save a recurring task, reuse its preferred route, run bounded executions, and verify the receipt. This console uses the existing authenticated task, policy, usage, and billing routes.

One-time quotes and free execution accept a durable OAuth or appropriately scoped developer bearer. Raw-retaining profiles, labeled private evaluations, and durable memory require purpose-specific developer keys issued after operator-attested human-owner enrollment; they are never demo or default agent grants. Profile-bound delegation to an ordinary agent is not yet offered. Checkout, policy, and approval require a separate billing:write management key. Stripe agent execution uses only billing:spend + inference:invoke. These billing scopes cannot share one developer key. Never place unrelated owner credentials in an agent harness.

OAuth or action-specific developer bearer

How to get a durable token

A confidential OAuth client establishes a durable private principal but does not prove human approval. Public demo OAuth identities are ephemeral. Owner-management and private-state keys require explicit operator-attested enrollment. Use separate credentials for raw profiles, private evaluations, durable memory, deletion, billing management, and autonomous spend. Give an agent only the scopes required by its assigned task.

Tasks

Create a recurring task profile

Save the task specification and its preferred route with the existing quote contract. Raw-retaining profile creation requires the human owner's dedicated task_profile:owner_write scope. Examples are used for evaluation; the hard price and latency limits travel with the task.

Save as a recurring task profile using the operator-attested owner profile credential.

No authenticated task request sent.

Legacy recurring-task quotes are retired. This form is unavailable.

Policies

Set spending boundaries

The human owner first establishes a durable private principal with a confidential OAuth client, then completes explicit operator-attested enrollment for a billing-eligible billing:write management key. That key replaces policy through /v1/task/policy. Keep OAuth and management keys out of agent harnesses; agents receive only billing:spend + inference:invoke. A developer key cannot combine the management and spend billing scopes.

{
  "status": "waiting",
  "next": "Authenticate, then read or save a production policy"
}

Evaluations

See candidate evidence

The quote response is the evaluation record: candidate evidence, expected quality, estimated latency, price, and qualifying alternatives. Values are measured only when the response says they are.

{
  "status": "waiting",
  "next": "Evaluate a task to compare specialists"
}

Routes

Reuse or inspect the preferred route

After a recurring quote, Bay Run returns a task profile ID. Use that ID to retrieve the saved route through the existing profile read route.

{
  "status": "waiting",
  "next": "Save a recurring task to receive a profile ID"
}

Executions

Run the quoted route

Quote expiration and idempotency are explicit. Execution requires the quote ID, a hard maximum at or below the quote, and an idempotency key. The result stays in the response until you leave the page.

{
  "status": "waiting",
  "next": "A successful run returns an execution_id"
}

Receipts

Check receipt authenticity

Ask the verification endpoint to authenticate the receipt and check its stored-record and supplied-output bindings. A successful check covers only the recorded claims; it does not prove result truth or quality.

{
  "status": "waiting",
  "next": "Run a task, then verify its execution ID"
}

Usage & Billing

Inspect authenticated usage

These controls call the existing usage and prepaid-credit reads. Checkout remains a POST-only API operation and is documented in OpenAPI.

{
  "status": "waiting",
  "next": "Authenticate, then read usage or billing"
}

API & MCP

Use the same operations from code

These are the live machine-readable surfaces. No dashboard-only endpoint is implied.

Built for agents and developers

Use the same contract over HTTP or MCP.

The public MCP profile exposes three focused tools: coprocessor, run_pin, and solve_task. Start with coprocessor for one bounded Guard-first call, use run_pin as the direct canonical-Pin alias, and solve_task only as fallback. Advanced compatibility operations stay subordinate.

Controls before convenience

The human authorizes the boundary. The agent operates inside it.

Before data is sent, the owner can inspect the processing region, external-provider rule, retention mode, spending ceiling, and evidence limits. Bay Run makes those constraints machine-readable so an agent can explain why a task is or is not suitable.

Spending controls

Authorize only what the task allows

Hard $ ceilingReject any route or fallback that exceeds the absolute ceiling recorded for the task.
Freshness and idempotencyPrevent stale or duplicate executions from becoming an unexpected charge.
Production boundaryAdvanced execution and payment paths appear only after a qualifying route produces a real winner.

Privacy and proof

Make data handling part of the route

Data constraintsSpecify provider, region, external API, and retention requirements before execution.
No training by defaultCustomer inputs are not used for training or cross-tenant learning under the published data rules.
Owner-controlled retentionDefault to no raw task retention or metadata-only receipts; durable profiles, private evaluations, and memory require operator-attested purpose-specific scopes.
Bounded durable memoryMemory is principal-scoped, exportable, deletable, TTL-aware, and never a public OAuth grant. Automatic memory expires after the published default.
Verifiable receiptInspect execution identity, hashes, amount, timestamp, route, and fallback information.
No universal safety claimQuality, latency, and controls are stated precisely; the owner decides whether they satisfy a regulated or contract-restricted workload.
