02 / ONE NETWORK, TWO SIDES

Built for callers.
Built for creators.

Model ownership, inference hosting, and API access stay separate—so each party gets one clear contract, one ledger, and the right controls.

A / FOR AI TEAMS

One key. The right model for every request.

Keep the OpenAI client you already use. Choose an exact model and constrain its configured deployment by region and retention policy.

  • OpenAI-compatible chat completions
  • Streaming, tools, and structured output
  • Fail-closed region and retention constraints
  • Per-request provider, latency, and usage receipts
quickstart.pyPYTHON
from openai import OpenAI

client = OpenAI(
  base_url="https://api.instamodel.ai/v1",
  api_key="mr_live_..."
)

response = client.chat.completions.create(
  model="northstar-demo/clauseguard-32b",
  messages=[{"role": "user", "content": prompt}]
)

B / FOR MODEL LABS

Your specialist model should earn while it works.

Bring a post-trained model or LoRA adapter. The private alpha records an immutable artifact, price, and royalty agreement while validation, deployment, and payout activation stay approval-gated.

03 / TRUSTED CONTROL PLANE

Build toward auditable inference.

Publisher submissions already snapshot immutable revisions, prices, and commercial terms. Connecting those snapshots to every paid gateway request is an explicit release gate for the marketplace.

THE MODEL NETWORK AFTER PRETRAINING

One key. A marketplace
of models.

Start with the public deterministic demo—no account or API key required. Paid provider routes open after checkout and cash-backed usage accounting are connected.
