Known issues we've tracked

Initial community quantizations (Q4 and below) showed degradation on reasoning tasks versus FP16 -- the MoE routing layers are sensitive to quantization. Q5/Q6 is the practical sweet spot for gpt-oss-120b
2025-09•Reddit r/LocalLLaMA, Hugging Face discussions
gpt-oss did not make the transition to OpenAI's GPT-5.x tokenizer -- still uses the older tokenizer from the GPT-4 era. Compatible with existing tooling but slightly less token-efficient than frontier OpenAI API models
