+1. **AutoResearch Paradigm**: Karpathy proved "AI autonomously doing ML research" works with just 630 lines of code — now spawning derivatives like ARIS and AI-Supervisor
 2. **"Vibe Training"**: HF Skills enables natural-language-driven model training lifecycle
-3. **GRPO > PPO**: DeepSeek's GRPO is becoming the default alignment method (no critic model, simpler, more stable)
+3. **GRPO Variants Proliferate**: f-GRPO (f-divergence family), Tree-GRPO (tree search, ICLR 2026), DAPO — GRPO is the new default, and specialized variants are emerging fast
 4. **RL Framework Explosion**: verl, DAPO, AReaL, slime — every major lab now has an open-source RL training framework
 5. **Self-Play Breakthrough**: Multi-agent self-evolution (SPIN, MAE, SPC) overcomes single-model self-training plateaus
-6. **Synthetic Data as Infrastructure**: Distilabel, Magpie, Cosmopedia make data generation a first-class pipeline stage
+6. **Synthetic Data as Infrastructure**: Distilabel, Magpie, Evidently make data generation a first-class pipeline stage; model collapse mitigation (Evol-Instruct) becoming standard
 7. **MCP Standardization**: Model Context Protocol adopted by OpenAI/Google/Microsoft as the "USB-C for AI agents"
 8. **Single-GPU Research**: Unsloth + nanochat + AutoResearch enables individual developers to do serious LLM research
-9. **Inference-Training Convergence**: vLLM/SGLang are now core components of RL training loops, not just serving
+9. **Inference-Training Convergence**: vLLM/SGLang/TGI are now core components of RL training loops, not just serving
