What Is a Multilayered AI Architecture?
And how can it supercharge the power of your app?
If one prompt takes an input and runs it through a series of filters and rules and fundamentally transforms the input data, then outputs it to you, multiple coordinated prompts compound those transformations substantially.
The separation of concerns between AI layers not only makes these systems more manageable, but also helps avoid confusing the AI with a million tasks—bolstering performance for the most important functionalities.
This approach is especially useful for systems aiming for near-perfect performance or simply more consistent results.
An Example from Emstrata
The Emstrata Cycle
The Emstrata Cycle is a standardized series of prompts that run on every turn in an Emstrata simulation.
This cycle:
- Retains a comprehensive memory of all entities in the simulation
- Plans and positions entities on an interactive coordinate plane
- Writes prose according to exacting instructions
- Captures secrets and memories
- Corrects all continuity errors after the narrative is written
No single prompt—or backend wizardry—could accomplish this alone.
Simplified Layers
- Groundskeeper (system memory)
- Discovery (planning / consequence handling)
- Narration (writing the narrative)
- Chron-Con (correcting minor errors)
Think Architecturally
Strategize for better platform results
Start with your actual goal, then break it down into steps.
If you were to perform this action yourself:
- What steps would you follow?
- What decisions would you make?
- What information would you need at each stage?
Write that down. That’s your workflow.
Once the workflow is formalized, identify the data transformations required at each step. Build prompts to automate those transformations—and then chain them together.
Illustrative example
- If your platform relies heavily on conversation history, token count and performance can suffer.
- A conversation consolidation layer may help.
- If you need true randomness, serve it from the backend instead of relying on LLM training data to approximate it.
Correction Layers
The referee of your platform
Correction layers catch errors after other layers have completed their work. They are your quality control.
They detect:
- Continuity breaks
- Logical inconsistencies
- Constraint violations
In Emstrata:
The Chron-Con layer runs after the narrative is written and checks things like:
- Did a character teleport without traveling?
- Did someone use an item they don’t possess?
- Are spatial coordinates consistent with the described action?
When you need one:
Use correction layers when your platform has complex requirements. Correcting before revealing the final answer significantly reduces bad outputs.
Reasoning / Strategy Layers
The decision-maker of your platform
Reasoning layers decide what should happen before anything is written.
They:
- Evaluate the current state
- Consider available options
- Assess consequences
- Choose a direction
In Emstrata:
Discovery handles this. It evaluates participant intent, simulation state, and narrative logic to determine outcomes—without writing prose.
Rule of thumb:
If you’re asking an LLM to both decide what happens and write it beautifully, you’re overloading a single prompt.
Reason first. Write second.
Memory Consolidation Layers
The stenographer of your platform
These layers distill what just happened into structured, retrievable memory.
They:
- Extract important details from verbose content
- Store data efficiently for future querying
- Maintain a system’s source of truth
In Emstrata:
Groundskeeper updates the comprehensive simulation state after Discovery and Narration complete their work.
Content Layers
The performer of your platform
Content layers generate the output users actually experience.
They:
- Take decisions from reasoning layers
- Pull context from memory layers
- Optimize for tone, pacing, and emotional resonance
In Emstrata:
The Narration layer writes the prose players read. It focuses on atmosphere—not logic or consistency (those are handled elsewhere).
Catch-All / Connector Layers
The clean-up crew of your platform
Some layers don’t fit neatly into one category. These hybrid layers handle glue-work between systems.
They often emerge when:
- Layers speak different “languages”
- Multiple layers need the same preprocessing
- No single layer should own a task outright
In Emstrata:
Chron-Con also extracts and tags secrets and memories for Groundskeeper.
- Narration shouldn’t stop to categorize secrets
- Groundskeeper needs them explicitly labeled
- Chron-Con bridges the gap
Cyclical vs Circumstantial Systems
And everything in-between
Cyclical systems
- Same prompts, same order, every time
- Predictable execution
- Easier debugging and cost estimation
Emstrata runs:
Discovery → Narration → Chron-Con → Groundskeeper
Circumstantial systems
- Execution path changes based on outcomes
- Routing layers determine what runs next
- More adaptive, more complex
Hybrid systems
- A reliable core cycle
- Conditional branches for edge cases
Most real-world systems land here—including Emstrata.
Agnostic Backend Interaction
What happens between AI layers
Why the backend matters:
- Data persistence: save transformed data for debugging and replay
- Reusability: present or reuse data later
- Unbiased judgment: the backend has no “opinions”
Emstrata example: Weighted randomness
- Discovery determines likelihood
- Backend rolls a number (1–1000)
- Backend confirms success or failure
- Narration receives the outcome
True randomness belongs outside the LLM.
Randomness Injection
A jolt of creativity
If your outputs feel trope-y or predictable, try Random Concept Injection.
Use randomness to:
- Generate novel character names
- Inject unexpected concepts
- Build characters from abstract archetypes
Any list of random strings can be injected into a decision-making process to break pattern lock-in.
Cost Considerations
Usage costs will increase
Multilayered systems cost more.
Each layer is an API call. A four-layer cycle can cost ~4× a single prompt.
The real question isn’t:
“How do I add layers cheaply?”
It’s:
“Does the quality improvement justify the cost?”
Optimization tips
- Use cheaper models for correction layers
- Cache aggressively in cyclical systems
- Cut layers that don’t earn their keep
Performance Considerations
Speed vs quality
More layers = more latency.
However:
- Independent layers can run in parallel
- Sometimes fewer, stronger prompts outperform many weak ones
Layering helps—but it’s not always the answer.
Hallucination Considerations
Avoid compounding errors
Hallucinations compound across layers.
If:
- A reasoning layer invents a fact
- A content layer writes it confidently
You’ve produced beautifully wrong output.
Critical rule:
Correction must happen before memory consolidation.
Bad data in memory becomes permanent—and grows worse over time.
Major Takeaways
What to remember
- Multilayered architectures compound transformations
- Layer types give you a vocabulary for intentional design
- Cyclical, circumstantial, and hybrid systems each have trade-offs
- Backends handle what LLMs shouldn’t: randomness, persistence, determinism
