CoreLLM: Local AI Playground Local LLM playground for Ollama and LM Studio
A local AI playground for Windows. Run and compare local LLMs with Ollama, LM Studio, Jan or any OpenAI-compatible endpoint.
CoreLLM is a desktop playground for running, testing and comparing large language models on your own PC. Connect to Ollama, LM Studio, Jan, LocalAI or any OpenAI-compatible endpoint, write custom system prompts, toggle reasoning modes such as DeepSeek-R1 and tune generation parameters.
A built-in hardware estimator uses your RAM to suggest models that will run well. It has no trackers, no cloud dependency and no telemetry. Prompts only leave your PC if you connect a remote endpoint.
