Use Continue with a free AI API

Set it up

1. Install the Continue extension for VS Code or JetBrains.
2. Open its config file (~/.continue/config.yaml) from the Continue panel’s settings.
3. Add the model below and select “ZeroLimitAI” in the model picker.

name: My Assistant
version: 1.0.0
schema: v1
models:
  - name: ZeroLimitAI
    provider: openai
    model: auto
    apiBase: https://www.zerolimitai.com/api/v1
    apiKey: zlai_your_key_here
    roles: [chat, edit, apply]

Replace zlai_your_key_here with your key. Base URL: https://www.zerolimitai.com/api/v1. Continue's own documentation

Good to know

• Use ZeroLimitAI for chat, edit and apply. Tab autocomplete needs a very fast, small model on every keystroke and would spend your daily calls quickly; keep a local model for that role.
• Only free models answer, and never through a provider that may train on your prompts. Context is at least 32K tokens, depending on the model.
• Need more than the free tier? Annual ($49/year) gives 2,000 calls a day and Lifetime ($99 once) 10,000. See plans.

If something goes wrong

401 invalid_key

The key is mistyped, revoked or missing the zlai_ prefix. Create a new one in your dashboard under Developer.

404 Not Found

The base URL must end in /api/v1 (https://www.zerolimitai.com/api/v1). Tools add /chat/completions themselves.

429 daily_limit

Your account used its calls for the day. The limit is per account, not per key, and resets at 00:00 UTC; the X-RateLimit-Remaining header shows what is left.

“Model not found”, or a model name you did not choose in the response

Any model ID is accepted: one we do not serve is routed by ZeroOptimize, and the response header X-ZeroOptimize-Substituted-From says what you asked for. Use “auto”.

Slow first word

Some free models think before answering. Keep streaming on so text appears as soon as it is written; a model that stays silent is replaced automatically.
