Describe the bug
On a fresh install, localai recommends spark-x2.5-4b. I download and run it, and I get
Error: failed to load model with internal loader: could not load model: rpc error: code = Internal desc = Failed to load model: /models/llama-cpp/models/Spark-X2.5-4B-Q4_K_M/Spark-X2.5-4B-Q4_K_M.gguf. Error: llama_model_load: error loading model: unknown model architecture: 'spark2_5'; llama_model_load_from_file_impl: failed to load model; llama_model_load: error loading model: unknown model architecture: 'spark2_5'; llama_model_load_from_file_impl: failed to load model
To Reproduce
Fresh install, install and start the recommended model. Fails consistently
