这一事件的深层原因是什么？

深入分析可以发现，Training follows a four-stage curriculum, each with distinct data mixtures and context lengths. Pre-training has two sub-stages: Stage 1 trains only the audio adaptor while keeping both AF-Whisper and the LLM frozen (max audio 30 seconds, 8K token context); Stage 2 additionally fine-tunes the audio encoder while still keeping the LLM frozen (max audio 1 minute, 8K token context). Mid-training also has two sub-stages: Stage 1 performs full fine-tuning of the entire model, adding AudioSkills-XL and newly curated data (max audio 10 minutes, 24K token context); Stage 2 introduces long-audio captioning and QA, down-sampling the Stage 1 mixture to half its original blend weights while expanding context to 128K tokens and audio to 30 minutes. The model resulting from mid-training is specifically released as AF-Next-Captioner. Post-training applies GRPO-based reinforcement learning focusing on multi-turn chat, safety, instruction following, and selected skill-specific datasets, producing AF-Next-Instruct. Finally, CoT-training starts from AF-Next-Instruct, applies SFT on AF-Think-Time, then GRPO using the post-training data mixture, producing AF-Next-Think.
