Six major alternatives to RLHF have emerged since 2022 (DPO, Constitutional AI, GRPO, KTO, ORPO, RLVR)
Claim as Clarified¶
Six major alternatives to RLHF have emerged since 2022 (DPO, Constitutional AI, GRPO, KTO, ORPO, RLVR)
BLUF¶
Substantially correct. All six named methods exist and have emerged as alternatives or complements to standard RLHF. DPO (2023), Constitutional AI (2022), GRPO (2025), KTO (2024), ORPO (2024), and RLVR (2024-2025) are all documented. Whether they are all 'major' is debatable — some like DPO and GRPO are widely adopted while others like KTO and ORPO have narrower use.
Scope¶
- Domain: AI alignment, sycophancy, enterprise AI
- Timeframe: 2022-2026
- Testability: Verifiable against published research and documentation
