LLM Playground is designed to be your all-in-one AI workspace, whether you’re chatting, generating images, analyzing documents, or collaborating in group rooms. While the built-in free model (LLMPlayground Fast or LLMPlayground) covers basic chat needs, connecting your own provider unlocks additional features and models. For example, image generation requires a connected provider like Airforce or Pollinations, and advanced users may prefer specific models for coding, research, or creative tasks.
Bringing your own key also gives you control over costs and usage. Your provider bills you directly at its own rates, and LLM Playground encrypts your credentials for security. This flexibility means you can switch between models or providers without losing access to your conversations, documents, or automations.
Supported Providers: Who Can You Connect?
Each provider offers its own selection of models, pricing, and features. For example, Airforce might be ideal for image generation, while InferencePort could provide access to newer or specialized models like sharktide/inferenceport-ai-gpt-4.1 or qwen3-coder-480b-a35b. The key is to check your provider’s documentation to see which models it supports and how they align with your needs.

Free Built-In Model vs. Bring-Your-Own-Key
The free built-in model is perfect for casual users or those who want to try LLM Playground without any setup. However, if you need specific models, image generation, or advanced features like automations, connecting your own provider is the way to go. The good news? You can switch between the free model and your connected provider at any time.

| Cost | Free, unlimited messages | Provider’s pricing applies |
| Models | LLMPlayground Fast, LLMPlayground | Any OpenAI-compatible model (e.g., gpt-4o, gemini-3.5-flash) |
| Image generation | Not available | Available (e.g., via Airforce, Pollinations) |
| Advanced features | Basic chat, document analysis | Deep research, automations, custom themes |
| Provider control | None (built-in) | Full control over model and provider |
