Based on the research, here are the cutting-edge multi-step reasoning techniques:

1. **Chain-of-Thought (CoT) Variants**:
   - Tree-of-Thoughts (ToT): Explores multiple reasoning paths
   - Graph-of-Thoughts (GoT): Non-linear reasoning graphs
   - Algorithm-of-Thoughts (AoT): Algorithmic reasoning patterns

2. **Self-Consistency & Verification**:
   - Multiple sampling with majority voting
   - Self-verification loops
   - Cross-validation between different models

3. **Retrieval-Augmented Generation (RAG)**:
   - FLARE: Forward-Looking Active Retrieval
   - Self-RAG: Self-reflective retrieval
   - Corrective RAG: Error correction loops

4. **Multi-Agent Approaches**:
   - Debate frameworks for consensus
   - Red team/blue team validation
   - Constitutional AI principles

5. **Factual Grounding**:
   - Citation-backed responses
   - Source attribution
   - Fact-checking pipelines
