Let's get started!
Before we start, here's what makes AI Crucible different: instead of asking one AI model for an answer, you'll orchestrate 3-4 models working together through a structured strategy. Think of it as assembling a team of experts rather than consulting just one advisor.
The four key decisions you'll make:
Pro Tip: Not sure what to ask? The suggested prompts at the bottom of the input field provide excellent starting points for business strategy, technical analysis, creative writing, and more. They show best-practice prompt structure you can learn from.
Let's walk through the basics. We'll keep it simple so you can get started quickly.

New to AI Crucible? You don't have to start from scratch. At the bottom of the prompt input area, you'll find professionally crafted sample prompts covering common use cases:
How to use suggested prompts:
These prompts are designed to demonstrate best practices: clear context, specific requirements, and structured deliverables. They're excellent examples to learn from, even if you modify them significantly. Many prompts include a recommended strategy (indicated by an emoji) to help you get started quickly.

What makes a good prompt?
✅ Be specific - Include context, audience, and goals ✅ Set constraints - Word count, tone, format ✅ Define deliverables - What exactly do you want? ✅ Provide examples - Show what good looks like (optional)
Example prompt structure:
[What you want created]
CONTEXT:
- [Background information]
- [Target audience]
- [Current situation]
REQUIREMENTS:

What's the Arbiter Model?
The arbiter is like a "judge" that:
Pro tip: You can change the arbiter model in Chat Defaults (/user/chat-defaults) for higher-quality analysis.
Not sure which strategy, models, or rounds to pick? Open the AI Prompt Assistant (click the AI Assistant button or press Cmd+A / Ctrl+A). It analyzes your prompt in real-time, classifies it into one of 14 categories, and recommends the optimal strategy, models, round count, and arbiter — all with one-click apply.

AI Crucible has grown well beyond core ensemble chat. Here are the key features to explore:
Use the Search page (/search) to find past conversations by prompt text, strategy, or model. Filter by strategy type to quickly locate previous work.
Visit the Benchmarks page (/benchmarks) to see how different strategies and model combinations score across categories like creative, business, technical, and research prompts. Use this data to pick the best setup for your task.
In Settings → Evaluations (/user/evaluations), review detailed scoring and tagging data across your sessions. Tag evaluations for easy retrieval and track model performance over time.
Connect external Model Context Protocol servers in Settings → MCP (/user/mcp) to give your models access to external tools and data sources during ensemble runs. Add, configure, and manage MCP servers from a single page.
In Settings → Custom Models (/user/custom-models), connect any OpenAI-compatible API—self-hosted models, Ollama, OpenRouter, etc.—and use them alongside built-in models in your ensemble runs.
In Settings → Expert Personas (/user/experts), create and manage reusable expert personas for the Expert Panel strategy. Assign a default model and custom description to each persona so you can quickly assemble specialized panels.

New in Optimizations:
Don't start from scratch:
Cmd+A / Ctrl+A) for real-time prompt analysis, smart strategy/model recommendations, and one-click configuration — learn moreStart with Competitive Refinement for creative tasks (writing, marketing, brainstorming). Use Expert Panel for specialized perspectives on complex decisions. Use Debate Tournament to stress-test ideas. Try Chain-of-Thought for step-by-step reasoning and Red Team / Blue Team for adversarial security testing. See the Seven Strategies Guide for detailed comparisons.
3 models and 3 rounds is the sweet spot for most tasks ($0.15-0.25, 3-4 minutes). Use 2 rounds for simple tasks, 4+ models for complex analysis or debates. Enable Adaptive Iteration Count in Optimizations to let AI Crucible stop early when responses converge.
Your prompt likely needs more specificity. Instead of "Write a blog post about productivity," try: "Write an 800-word blog post for remote workers about productivity, focusing on time-blocking techniques. Tone: practical and encouraging." Include context, audience, constraints, and deliverables.
Yes! Pro users can add Custom Models via any OpenAI-compatible endpoint in Settings → Custom Models (/user/custom-models). This lets you connect self-hosted models, fine-tuned variants, or any provider that exposes an OpenAI-compatible API.
Yes! Click the Share button on any completed chat to generate a public read-only link or embed code. Manage all your shared chats in Settings → Public Chats.
ChatGPT gives you one model's perspective. AI Crucible coordinates multiple models through structured strategies—giving you more diverse, balanced, and higher-quality results by combining different models' strengths and having them learn from each other.
Prompts are only sent to models that you select. We don't train on your data, don't share it, and you can delete your history anytime.
You've just completed your first ensemble AI project! Here's what you learned:
Instead of asking one AI for an answer, you're orchestrating multiple AI models working together. It's like having a team of experts instead of consulting just one advisor.
The result? Better quality, more diverse perspectives, and higher confidence in your decisions—all for less than $0.20 and 3-4 minutes. Plus sharing, benchmarks, evaluations, and MCP tool integration to take your workflow even further.
Don't wait—try it now! Pick something you actually need, use one of the Quick Start Scenarios above, and see the difference ensemble AI makes.
Remember: The best way to learn is by doing.
