GPT

Use OpenAI, Anthropic, or Gemini models inside Visual Studio Code

🚀 Quick Start (30 seconds) <div id="getting-started"></div>

Prerequisite: an API key from your provider (OpenAI / Anthropic / Gemini).

1. Run GPT: Setup
2. Select any text in the editor
3. Press Alt + Shift + I (Ask GPT)

No key set? Ask GPT will prompt you to set one and automatically retry once.

How it works <div id="how-it-works"></div>

• You select text (or a full file) → GPT sends that content to the currently selected model/provider and returns a response.
• Responses are shown either in a new file or by replacing the selection (configurable).
• API keys are stored securely in VS Code SecretStorage when available.

Privacy & security

• API keys: stored in VS Code SecretStorage when available; otherwise stored for the current session only.
• Logging: debug logs intentionally avoid secrets and prompt contents.
• Chat history: kept in-memory during the session; you can export it manually.

How to use <div id="how-to-use"></div>

Ask GPT (selection) — recommended default

1. Select text
2. Run Ask GPT (Alt + Shift + I)

Ask GPT with File (whole file)

Use Ask GPT with File when you need full-file context (refactors, audits, “explain this file”).

🔑 Setup & API keys <div id="setup--api-keys"></div>

GPT: Setup

One onboarding flow:

1. Choose a provider (OpenAI / Anthropic / Gemini)
2. Set an API key if missing
3. Optionally pick a model

GPT: Set API Key (fast path)

Sets/updates the API key for the currently selected provider.

GPT: Manage API Keys

Manage keys across providers (view status, set/update, remove).

Legacy OpenAI keys previously stored in globalState are migrated automatically when SecretStorage is available.

---

🧠 Providers & models <div id="providers--models"></div>

• Default provider: OpenAI
• Switch provider: GPT: Change Provider
• Change model: GPT: Change Model

Model list behavior

• Pick from a built-in list or use Custom model id…
• Refresh model list (online) appears only after an API key is configured for the active provider

---

🧩 Project instructions (.gpt-instruction) <div id="project-instructions"></div>

Place a .gpt-instruction file in your workspace to automatically prefix each query with project-specific guidance.

• Multi-root: resolves per workspace folder based on the active document.

• Lookup modes:

  • workspaceRoot (default): reads <workspaceFolder>/.gpt-instruction
  • nearestParent: closest parent .gpt-instruction wins

• Nearest-parent behavior:

  • An empty .gpt-instruction suppresses parent instructions.
  • This mode can be more expensive in very large repos (recursive watcher).

• Size limits:

  • Content beyond the configured max is truncated with a warning.
  • In remote/virtual workspaces, very large files may be ignored for safety.

🛠️ Troubleshooting <div id="troubleshooting"></div>

Invalid or missing API key

• Run GPT: Setup (recommended) or GPT: Set API Key
• Confirm provider via GPT: Change Provider

“Model not available”

• Run GPT: Change Model
