Tree of Thoughts (ToT) — Prompting Guide & Examples
Tree of Thoughts extends chain-of-thought by exploring multiple reasoning paths simultaneously, evaluating each branch, and selecting the most promising direction. Instead of a single linear chain, the model considers several possible approaches before committing.
How It Works
The model generates multiple possible next steps at each reasoning stage, evaluates which paths are most promising (using self-evaluation or voting), prunes unlikely paths, and continues expanding the best branches. Think of it as BFS/DFS applied to reasoning.
When to Use
Use ToT for creative problem-solving, strategic planning, puzzle-solving, game playing, and any task where the first approach might not be optimal. Especially powerful for tasks with multiple valid solution paths.
Model-Specific Tips
ChatGPT / GPT-4
GPT-4 handles ToT well with explicit instructions to generate and evaluate multiple paths. Use structured prompts with numbered alternatives and scoring criteria.
Claude
Claude excels at ToT. Ask it to 'consider 3 approaches, evaluate each, then pursue the best.' Claude's long context helps maintain multiple branches.
Gemini
Gemini supports ToT reasoning. Use clear structure with branch generation and evaluation steps. Gemini 1.5 Pro's large context helps with complex trees.
Pros & Cons
Pros
- ✓ Explores multiple solution paths
- ✓ Finds better solutions than linear reasoning
- ✓ Self-evaluating — prunes bad approaches
- ✓ Excellent for creative and strategic tasks
Cons
- ✗ Very high token usage (3-5x CoT)
- ✗ Complex to implement properly
- ✗ Slower due to branching exploration
- ✗ Overkill for simple tasks
Example Prompts
I need to solve this puzzle. Generate 3 different approaches, evaluate each one's likelihood of success, then pursue the most promising path: Puzzle: Arrange the digits 1-9 in a 3x3 grid so every row, column, and diagonal sums to 15.
Brainstorm 3 different go-to-market strategies for a B2B AI writing tool. For each strategy, rate its potential (1-10) on: speed to revenue, scalability, and capital efficiency. Then develop the highest-rated strategy in detail.
Consider 3 different architectures for a real-time chat application serving 1M concurrent users. Evaluate each on: latency, cost, complexity, and reliability. Recommend the best approach with justification.
