Supported Models

RepoPrompt integrates with multiple AI providers through their APIs, offering access to a wide range of language models for your development needs.

Supported AI Providers​

OpenAI​

  • Available Models: GPT-5.4 family (including GPT-5.4 Pro via API), GPT-5 Mini
  • API Setup: Requires an OpenAI API key from OpenAI Platform
  • Features: Most models support diff editing for precise code changes
  • GPT-5.5 note: GPT-5.5 Low/Medium/High are available only through Codex CLI, and GPT-5.5 Pro is available only on ChatGPT Pro web. Do not try to configure GPT-5.5 as an OpenAI API model — the OpenAI API continues to serve the GPT-5.4 family.

Anthropic​

  • Available Models: Claude 3.5 Sonnet, Claude 3.5 Haiku, Claude 3.7 Sonnet, Claude 3.7 Sonnet Thinking, Claude 3.7 Sonnet Thinking Max
  • API Setup: Requires an Anthropic API key from Anthropic Console
  • Features: Claude 3.5 and 3.7 models excel at precise code editing and understanding context

Gemini​

  • Available Models: Gemini 1.5 Pro, Gemini 1.5 Flash, Gemini 1.5 Flash 8b, Gemini 2.0 Flash, Gemini Flash Thinking, Gemini 2.5 Pro
  • API Setup: Requires a Gemini API key from Google AI Studio
  • Features: Gemini 2.0 Flash and Gemini 2.5 Pro offer excellent performance for whole file editing

DeepSeek​

  • Available Models: DeepSeek V3, DeepSeek R1
  • API Setup: Requires a DeepSeek API key from DeepSeek Platform
  • Features: Both models support diff editing with strong code understanding capabilities

GitHub​

  • Available Models: GitHub-hosted GPT models
  • API Setup: Authenticate with GitHub account
  • Features: Access to OpenAI models for GitHub users without requiring separate API keys

Azure OpenAI​

  • Available Models: Custom deployed models via Azure
  • API Setup: Requires Azure resource name, deployment ID, API version, and key
  • Features: Enterprise-grade deployment with custom resource management

OpenRouter​

  • Available Models: Access to models from various providers, including DeepSeek, Qwen, OpenAI, Anthropic, and Google
  • API Setup: Requires an OpenRouter API key
  • Features: Single API to access multiple providers, including options not directly supported

Local Models (Ollama)​

  • Available Models: Any model deployed through Ollama or other local services
  • API Setup: Configure URL (default: http://localhost:11434) and select available models
  • Features: Run models locally without sending data to external services

Custom Provider​

  • Features: Connect to any OpenAI-compatible API endpoint
  • API Setup: Configure base URL, API key, and other parameters
  • Use Cases: Self-hosted models or alternative API providers

Setting Up API Keys​

To configure your API keys in RepoPrompt:

  1. Open RepoPrompt's settings
  2. Navigate to the "API Keys" tab
  3. Enter your API key for each service you want to use
  4. Click "Validate & Save" to securely store and verify your key

API keys are stored securely in your system's keychain and never shared with external services beyond the respective AI provider.

Model Capabilities​

Different models have different capabilities when it comes to code editing:

  • Diff Editing Capable: Models like Claude Sonnet 4.5, DeepSeek V3, GPT-5.4, and Gemini 3 Pro can provide precise diff edits that only modify the necessary parts of a file.
  • Whole File Editing: All models can rewrite entire files, with models like Gemini Flash 2.0 excelling at this task for smaller files.
  • GPT-5.5 (Codex CLI / ChatGPT Pro): GPT-5.5 Low/Medium/High are Codex CLI recommendations and should not be configured as OpenAI API or OpenRouter model IDs. GPT-5.5 Pro is ChatGPT Pro web only.

You can customize model capabilities in the Model Overrides settings, enabling or disabling features like diff editing and streaming for specific models.

Pro Edit Settings​

RepoPrompt's Pro Mode intelligently distributes editing tasks across different models:

  • Planning: The primary model you select handles overall planning and complex decisions
  • Simple Edits: Typically handled by faster, more cost-effective models like Gemini Flash 2.0
  • Complex Edits: Assigned to powerful models like Claude 3.7 Sonnet for difficult changes
  • Large Files: Processed by models with high context windows and diff capabilities

The application automatically adjusts editing strategies based on file size and complexity.
