I Built AI Workflows That Cost $0.18 to Run at MiniMind AI
The real story behind cost-efficient AI workflows — and why most teams are doing it completely wrong.
The Fundamental Problem With How Most People Use AI
When you ask a chatbot to research your competitors, here's what happens:
- AI receives your request
- AI thinks about how to approach it
- AI plans the research steps
- AI executes the research
- AI formats the output
You pay for all five steps. Every. Single. Time.
The thinking and planning phases are the expensive part. And you're buying them repeatedly, for every user, on every run.
The Pre-Built Workflow Architecture
The solution is surprisingly simple:
Do the thinking once. Let everyone execute cheaply forever.
On MiniMind AI Workflows, every workflow is pre-architected:
- Steps are fixed and optimised
- Token paths are predetermined
- Output structure is defined in advance
- Credits go 100% to execution, not planning
A user running the Competitor Intelligence workflow isn't paying for the AI to figure out how to research competitors. That thinking was done once — by a human architect — and encoded into the workflow permanently.
The Workflow Engine Capabilities
Building cost-efficient workflows requires a complete primitive set. Here's what powers MiniMind's workflows:
Execution patterns:
- Sequential steps — ordered execution with state passing
- Parallel steps — simultaneous execution for independent tasks
- Looping — iteration over lists with consistent processing
- Branching — conditional paths based on intermediate outputs
Interaction patterns:
- Human-in-loop approval — user reviews before proceeding
- Selection inputs — dropdown configuration without typing
- Progressive input fields — structured data collection
Integration patterns:
- LLM calling — multi-model AI execution
- Internal tool calling — platform capabilities as workflow steps
- Web search and fetch — live data retrieval
- Function calling — custom logic execution
These primitives compose into powerful workflows. The Competitor Intelligence Workflow uses web fetch, parallel research, LLM analysis, confidence scoring, and structured artifact generation — all pre-wired.
Why Human-in-Loop Changes Everything
Most AI workflow tools treat human approval as an afterthought. In MiniMind's architecture, it's a first-class primitive.
Why does this matter?
Because it separates AI execution from human judgment at exactly the right moments.
The AI researches, aggregates, and drafts. The human reviews before the workflow commits to the next phase. This isn't just about quality — it's about accountability, especially important as AI regulation tightens globally.
The Startup Launch Kit Workflow uses human approval at the strategic positioning step — because market positioning decisions should have a human in the loop, not be fully automated.
The Credit Math That Makes This Viable as a Business
Let me show the unit economics that make this model work:
| Metric | Value |
|---|---|
| Credits per competitor research run | 10–26 |
| User subscription | 1,000 credits for $7 |
| Cost per research run | $0.07–$0.18 |
| Runs per $7 subscription | 38–100 |
Compare this to enterprise research tools charging $200–500/month for similar output.
The efficiency comes entirely from pre-built workflow architecture. Not from cheaper models. Not from lower quality. From eliminating the planning overhead on every execution.
The Design Doc Discipline
Here's the part most workflow builders skip: the design work is the expensive part, and you only do it once.
Every MiniMind AI workflow was designed against a detailed specification before a single line was coded. Steps mapped. Token paths calculated. Output structures defined. Edge cases documented.
This upfront investment is what makes every subsequent run cheap and consistent.
Think of it like a manufacturing process. The expensive part is designing the production line. Once it's built, each unit rolls off cheaply and identically.
Most AI teams skip the production line design. They just ask the AI to figure it out each time.
The Four Workflows Live Today
🕵️ Competitor Intelligence
Multi-source research with confidence-aware scoring. The most complex workflow — optimised over multiple iterations to hit the 26-credit ceiling consistently.

♻️ Content Repurposing
Transform one piece of content into platform-specific assets. Sequential execution with parallel generation for different channels.
Content Repurposing Workflow
🏗️ PRD to System Architecture
Take a product requirements document and generate technical architecture. Structured decomposition with human review at key decision points.
PRD to System Architecture Workflow
🚀 Startup Launch Kit
From idea to launch strategy. Combines market research, SWOT analysis, positioning, and go-to-market planning in one pre-built flow.
Startup Launch Kit Lite Workflow
What's Coming
The current primitive set — sequential, parallel, looping, branching, human-in-loop, web search, function calling — composes into virtually any workflow imaginable.
Upcoming: Market Entry Intelligence, SEO Content Brief, Startup Due Diligence, Investment Thesis Validation, and more.
Each new workflow reuses existing primitives. Build time decreases with every addition. The library compounds.
The Lesson for Every AI Builder
The cost problem isn't the models. The models are getting cheaper every month.
The cost problem is architecture. Specifically: who pays for the thinking, and how often.
If your users pay for thinking on every run → costs spiral → Microsoft problem.
If your architecture pays for thinking once → costs stay flat → sustainable unit economics.
Build the production line. Let users run the machines.
