Willison posted his hands-on the same day Meta shipped, calling out the clean Apache 2.0 license as the headline and testing the model on code exploration and image description with positive results. He flagged the GGUF build on Hugging Face immediately, with llama.cpp, MLX and ExecuTorch integrations landing over the following days. His read matters here because he has spent a year publicly hunting for a local model good enough to run agent loops on a laptop — this is the closest he has said any open-weights release has come.
