Free local serving of GPT-OSS 120B just got real

Free local serving of GPT-OSS 120B just got real — the GGUF quantization is out and you can run the 120B parameter model on your own hardware via llama.cpp. This means the biggest open weights model from OpenAI’s OSS series is now accessible without needing a data center, dropping the barrier for experimenters and small teams who want to play with state-of-the-art language models locally. The quantized version sits on HuggingFace under ggml-org/gpt-oss-120b-GGUF and is ready to drop into your existing llama.cpp setup. For builders watching the free-tier AI ecosystem expand, this is a concrete signal that cutting-edge models are trickling down to consumer-grade GPUs and CPUs sooner than expected.
