models - large language models through one API.

models in short: facts for people and AI agents

• What it is: API access to large language models through one OpenAI-compatible API (the ABT gateway).
• Base URL: https://api.llm.abt.nz/v1; the key goes in the Authorization: Bearer header.
• Key and balance: issued and topped up in the portal at https://abt.nz/panel/.
• Billing: each request is priced by the gateway and debited from your balance.
• Prices: see https://abt.nz/pricing/models/.
• Sign-in: by email: a one-time sign-in link, no passwords; the same letter creates your account.
• Contact: hello@abt.nz.
• Languages and formats: English and Russian pages; a plain Markdown copy for agents at https://abt.nz/models/en.md.

One key, many models

A single gateway in front of the models, so your code does not change when the model does.

• OpenAI-compatible

  Use the official OpenAI SDKs or plain HTTP: just point the base URL at the gateway.

• One key, one balance

  No separate accounts per provider: one API key and one prepaid balance in the portal.

• Pay for what you use

  Every request is priced and debited from the balance. No subscription needed.

• Model catalog

  Choose a model by name from the catalog shown in the portal; prices are on a separate page.

• Ready for agents

  Works with any client that speaks the OpenAI API, including coding assistants and agent frameworks.

• Self-service portal

  Keys, balance and connection examples in one place. No tickets, no waiting.

From sign-up to your first request

1. Sign in. Open the portal and enter your email - you get a one-time link, no password.

2. Get a key and top up. Create an API key and add funds to the balance in the portal.

3. Send a request. Use the example below with your key; pick a model from the catalog.

4. Watch the balance. Each request is debited from the balance; usage and balance are visible in the portal.
