1. yes. https://www.alphaxiv.org/abs/2607.bonsai-27b table 14 shows that bonsai retains roughly 95% of the fp16 27b model's average performance and outperforms post-training quantization at a similar bit width. it doesn't directly compare against every top 10-18b model, but it is clearly still performing like a large model.
2. quantization != native low precision training. a model trained in native ternary should generally outperform a full-precision model quantized after the fact.
even if a ternary model only retains 90-95% of the performance of its fp16 equivalent, who cares? if a 200b ternary model retains most of the capability of the 200b fp16 model while using a fraction of the memory and bandwidth, it can be substantially less efficient per parameter and still dominate a smaller fp16 model under the same hardware budget.
