A Language-Native Control Framework Inside LLMs – Why I Built Language Construct Modeling (LCM)

Hi all, I am Vincent Chong.

I’ve spent the past few weeks building and refining a control framework called Language Construct Modeling (LCM) — a modular semantic system that operates entirely within language, without code, plugins, or internal function rewrites. This post isn’t about announcing a product. It’s about sharing a framework I believe solves one of the most fundamental problems in working with LLMs today:

We rely on prompts to instruct LLMs, but we don’t yet have a reliable way to architect internal behavior through those prompts alone.

LCM attempts to address this by rethinking what a prompt is — not just a request, but a semantic module capable of instantiating logic, recursive structure, and state behavior inside the LLM. Think of it like building a modular system using language alone, where each prompt can trigger, call, or even regenerate other prompt structures.

What LCM Tries to Solve:

• Fragile Prompt Behavior 

→ LCM stabilizes reasoning chains by embedding modular recursion into the language structure itself.

• Lack of Prompt Reusability 

→ Prompts become semantic units that can be reused, layered, and re-invoked across contexts.

• Hard-coded control logic 

→ Replaces external tuning / API behavior with nested, semantically-activated control layers.

How It Works (Brief): • Uses Meta Prompt Layering (MPL) to recursively define semantic layers

• Defines a Regenerative Prompt Tree structure to allow prompts to re-invoke other prompt chains dynamically • Operates via language-native intent structuring rather than tool-based triggers or plugin APIs 

Why It Matters:

Right now, most frameworks treat prompts as static instructions. LCM treats them as semantic control units, meaning that your “prompt” can become a framework in itself. That opens doors for: • Structured memory management (without external vector DBs)

• Behavior modulation purely through language • Scalable, modular prompt design patterns • Internal agent-like architectures that don’t require function calling or tool-use integration 

I’ve just published the first formal white paper (v1.13), along with appendices, a regenerative prompt chart, and full hash-sealed verification via OpenTimestamps. This is just the foundational framework —a larger system is coming.

LCM is only the beginning.

I’d love feedback, criticism, and especially — if any devs or researchers are curious — collaboration.
