IDE & Client Setup

What "IDE support" means

GLM5 exposes an OpenAI-compatible API. Use it inside VS Code or another IDE through a client or coding agent that supports a custom OpenAI-compatible provider.

This documentation does not claim that GLM5 ships a first-party VS Code extension.

Every client needs these three values together:

Verify the key before configuring an IDE

curl https://glm5.app/api/v1/models \
  -H "Authorization: Bearer $GLM5_API_KEY"

Then make a small Chat Completions request. If both calls work but the IDE returns 401, check that the client is using a custom provider and that its Base URL is exactly https://glm5.app/api/v1.

OpenAI SDK

import OpenAI from 'openai';

const client = new OpenAI({
  apiKey: process.env.GLM5_API_KEY,
  baseURL: 'https://glm5.app/api/v1',
});

const result = await client.chat.completions.create({
  model: 'glm-5.3-flash',
  messages: [{ role: 'user', content: 'Hello' }],
});

OpenCode

Use @ai-sdk/openai-compatible, set baseURL to GLM5, and supply your key through an environment variable. Add the GLM5 public model IDs you intend to use.

Oh My Pi (omp)

For omp, define a custom provider in ~/.omp/agent/models.yml:

providers:
  glm5:
    baseUrl: https://glm5.app/api/v1
    api: openai-responses
    apiKey: GLM5_API_KEY
    models:
      - id: glm-5.3-flash
        name: GLM 5.3 Flash
        contextWindow: 1000000
        maxTokens: 8192

Set GLM5_API_KEY in the same shell, then run omp models glm5 to verify the provider. To make it the default model, set modelRoles.default to glm5/glm-5.3-flash in ~/.omp/agent/config.yml.

Pi / Continue / other clients

Choose the client's custom OpenAI-compatible provider mode. Do not select a built-in OpenAI provider that hardcodes api.openai.com unless the client lets you override the Base URL.

Troubleshooting

After a GLM5 API request reaches the service, responses include X-Request-ID. Open Activity → Logs and search that ID to inspect status, model, key, tokens, credits, latency, and error code without exposing prompt text.
