AICanRun is a compatibility checker that tells you which local large language models your smartphone can run based on its chip, RAM, and memory bandwidth. It covers 132 phones, 51 models, and 294 quantization variants, using transparent RAM math that accounts for weights, KV cache, and runtime overhead. For each supported model, it provides the recommended quantization level, estimated inference speed in tokens per second, and which app to use for deployment. No installation is required to use the tool.
