Which Tier

Pick one:

• Obvious choice - a tool an experienced Python developer would name when asked "what do I use for this?"
• Challenger - not yet the obvious choice, but a credible successor to one. Give adoption-trajectory evidence, not popularity alone.

Explain:

Obvious choice

Axolotl is one of the standard open-source fine-tuning and post-training frameworks in the Python LLM ecosystem (12.4k+ GitHub stars, widely adopted across major open-source model releases). It provides unified support for leading architectures (Llama, Mistral, Gemma, Qwen, DeepSeek) with FSDP, DeepSpeed, LoRA/QLoRA, and alignment techniques (DPO, IPO, KTO, ORPO, GRPO). The Fine-tuning subcategory currently only lists unsloth, making axolotl an obvious addition.
