Zed Editor Integration Guide

Zed is a high-performance modern code editor with built-in AI assistant capabilities that supports multiple large language models. This guide explains how to integrate Zed Editor with OPE.AI to leverage cutting-edge models for programming assistance.

Quick Start

1. Obtain API Key

Visit the OPE.AI Console and create your dedicated API Key.

2. Add Provider

You can configure OPE.AI using one of the following methods:

Visual Configuration (Recommended)

Add configuration through the Agent Panel visual interface without manually editing JSON files.

Steps

1. Press Cmd + Shift + A (Windows/Linux: Ctrl + Shift + A) to open the Agent Panel.
2. Click + Add Provider in the LLM Providers area.
3. Enter the configuration information according to the table below:

No.	Field Name	Configuration Value
①	Provider Name	OPE.AI
②	API URL	https://api.ope.ai/v1
③	API Key	Your OPE.AI API Key
④	Model Name	Claude-4.6-Sonnet
⑤	Max Completion Tokens	200000
⑥	Capabilities	Check Tools and Images (model-dependent)

4. Click + Add Model to continue adding other models (e.g., Claude-4.6-Opus, GPT-5.4-Pro).

Edit settings.json

Suitable for batch adding multiple models; editing the configuration file is more efficient.

Steps

1. Press Cmd + , (Windows/Linux: Ctrl + ,) to open settings.
2. Click Edit in settings.json in the top right corner.
3. Add the following content to the configuration file:

~/.config/zed/settings.json

          }
        ]
      }
    }
  }
}

4. After saving the file, Zed will automatically display an API Key input dialog; enter your OPE.AI API Key.

tip

The settings.json method is suitable for batch model management; simply edit the available_models array to add/remove models.

Security Note: API Keys are securely stored in the system keychain (macOS Keychain / Linux Secret Service) and are not written to configuration files in plain text.

Troubleshooting

OPE.AI Provider Not Showing in Model List

• Confirm that the Provider has been correctly added in the Agent Panel or settings.json.
• Try restarting Zed Editor.
• Check if the API URL is correct: https://api.ope.ai/v1

Authentication Error

• Confirm API Key format is correct (starts with sk-).
• Open command palette Cmd/Ctrl + Shift + P → Search for language model: reset credentials → Re-enter Key.
• Visit OPE.AI Console to confirm Key validity.

Tool Use Not Responding

• Confirm that "capabilities": { "tools": true } is set in the configuration.
• Some models do not support tool calls; refer to the quick reference table above.

Model Returns Error or Timeout

• Check network connection, confirm access to https://api.ope.ai.
• Try switching to another model (e.g., Claude-4.5-Haiku) for testing.
• View Zed logs: Help > View Logs.
