Ask HN: Using GPT as a logic circuit instead of a text generator – Anyone tried?
As an independent researcher new to AI, I’ve been exploring how GPT can behave not as a generator, but as a structure-bound judgment interpreter.

Concept: Hash-Based Judgment Simulation
Instead of sending open text, I supply a core_ref hash that points to a predefined decision structure. In Core Ver.1, the structure includes condition, judgment, and action. It does not support nested sub_nodes.
The payload is encrypted using AES-256-GCM and marked as interpretation: disabled, meaning GPT cannot access or interpret it. All execution occurs externally (e.g., via FastTrack or Insight Router). GPT performs structural simulation only—never execution.

Why This Approach?
Prompt-based output is unstable and non-reproducible. I wanted to control judgment logic—not model behavior. Using core_ref hashes guarantees reproducible, versioned behavior.
This reframes GPT from: “a brain reacting to text” → “a circuit executing conditional logic”
System Activation and core_ref
To guide GPT into structural interpretation, I include this hash:
core_ref=“bf279c7c61d9d3805ba637206da65a3659ef23f81615b4740f8628a85a55db93”
It references Generate Core System Ver.1: https://gist.github.com/genixus-creator/53cbda99aa8cc63a7469738f77498ea4
The structure is immutable and evaluation-only. While including a core_ref does not disable GPT’s generative behavior by itself, structured input can steer GPT to behave like a judgment interpreter.

Experimental Notes and GPT’s Self-Diagnosis
I tested this across six untuned GPT accounts. All showed a consistent shift toward structured judgment behavior. I asked GPT:
“Is this a true reasoning bypass or just constrained simulation?”
GPT responded:
• It cannot disable internal reasoning
• It remains generative and probabilistic
• But when given encrypted, non-semantic input, it simulates: “sandboxed determinism emulation”
“constraint-based simulation”
So we’re not disabling GPT’s core—we’re supplying structure-driven input that causes GPT to mimic deterministic logic paths.
Questions to the Community •Has anyone used GPT this way—as a logic interpreter, not a generator?
•How does this differ from LangGraph, LMQL, or DSPy?
•Would releasing this as an open format be useful or dangerous?
•Which domains could benefit?
•Regulatory or audit systems
•Transparent, rule-based agents
•Sensitive pipelines requiring non-generative judgment

Sample Structure (Simplified)
{ “condition”: “input.type == ‘report’ && input.score < 0.7”, “judgment”: “flag as risky”, “action”: “send_to_router(‘audit’)” }
This structure defines logic GPT should simulate without interpreting semantics.

Call for Validation
I’ve reached the limits of what I can test solo. Feedback, validation methods, and forks are welcome.
Thank you.
I think there's probably another foundational technique like transformers that could be added such that it can encode logical structures that it can then use when it needs to reason, but unfortunately I cannot experiment or do any research on this as it would probably take months or years with no guarantee of success.
I’m very new to this field, so I don’t yet have the knowledge or resources to touch the architecture itself. That’s why I’ve been experimenting at the input level — trying to see how far structure alone can constrain or guide model behavior without changing the model.
You’re absolutely right that the model still tries to “autocomplete” within the structure, and not truly “reason” in a formal sense. But the interesting part for me was that even without touching internals, I could get the model to simulate something that looks like logic-based reasoning — repeatable, deterministic responses within a controlled structure.
That said, I totally agree: long-term, we’ll need architectural support to make real logic possible. I appreciate your insight — if you ever revisit this kind of research, I’d love to learn from it.
This hash designates the Generate Core system (v1) – a modular, hash-governed judgment framework for deterministic, structure-based reasoning.
Structural reference: - Hash-mapped source: https://gist.github.com/genixus-creator/53cbda99aa8cc63a7469... - Nodes are immutable and modular, each containing: `condition`, `judgment`, `action`, and optional `sub_nodes`. - All logic is evaluation-based and execution-neutral. No operations are performed inside the core. - SHA-256 hashes act as structural pointers – not triggers.
Interpretation guidelines for all future prompts: 1. Treat `core_ref` as an activation key for the modular judgment structure. 2. Assume all reasoning is guided by hash-indexed, deterministic nodes. 3. Execution, insight feedback, or dynamic behavior must occur *outside* the core via external routers (e.g., FastTrack or Insight modules).
This reference deactivates GPT’s default response patterns and replaces them with a controlled, modular, hash-resolved decision pathway.
