Fine-tuning training quality improves for Qwen3.5, Qwen3.6 and Nemotron 3 models

Training quality has improved for fine-tuning on the following models:

• Qwen/Qwen3.5-0.8B.
• Qwen/Qwen3.5-2B.
• Qwen/Qwen3.5-4B.
• Qwen/Qwen3.5-9B.
• Qwen/Qwen3.5-27B.
• Qwen/Qwen3.5-35B-A3B.
• Qwen/Qwen3.5-35B-A3B-Base.
• Qwen/Qwen3.5-122B-A10B.
• Qwen/Qwen3.5-397B-A17B.
• Qwen/Qwen3.6-27B.
• Qwen/Qwen3.6-35B-A3B.
• nvidia/Nemotron-3-Nano-Omni-30B-A3B-Reasoning-BF16.
• nvidia/NVIDIA-Nemotron-3-Super-120B-A12B-BF16.

Other models are unchanged. No actions or setting changes are required to get the improvement. To pick it up on a model you've already tuned, start a new job with the same data and settings. A job you run after this release will not reproduce the loss curve of an earlier run on the same data and settings.
