Openllm is the most flexible LLM communication app which you can use with any OpenRouter compatible model (standard, thinking) models and any other OpenAI-compatible API.

Use ChatGPT, Claude, DeepSeek, GLM 4.6 and more models via OpenLLM.
Add new models seamlessly via model name and they appear immediately in your model list.

Tired of OpenRouter? Use Groq, DeepSeek, DeepInfra and other providers for higher speed and broader model access. Simply enter the API URL, model name and API Key and select 'Custom' from model list.
