Everything you need to plug CheapAI into your tooling — setup guides for popular agents, API reference, FAQ.

Zed

Editor with a built-in agent

Create an API key on the Keys page and copy it.

Open settings.json (cmd-shift-P → zed: open settings) and add the provider. List only the models you actually use - each one shows up in the picker.

          {

          },
          {
            "name": "gpt-5.6-sol",
            "display_name": "GPT-5.6 Sol",
            "max_tokens": 200000,
            "max_output_tokens": 32000,
            "capabilities": { "tools": true, "images": true }
          }
        ]
      }
    }
  }
}

Put the key in the Agent settings UI, or export CHEAPAI_API_KEY in your shell.

bash

export CHEAPAI_API_KEY="<ваш ключ>"

Do not put the key into settings.json - Zed ignores it there and keeps keys in the system keychain. The env var name is derived from the provider id: cheapai → CHEAPAI_API_KEY. Rename the provider and the variable name changes with it.

Model ids must match the catalog exactly - see the list.
