reasoning your agents can reuse

agent reasoning
is rebuilt from scratch.
every single run.

Delapan models a domain's reasoning once, reproducibly — then any agent injected with it performs the task better, on grounding it can show its work for.

01 — the problem

Right now, every agent
re-derives the same reasoning.

Every run starts from scratch. Your agents explore the domain, reconstruct the structure, re-derive the understanding — then throw it all away. Same task, same agent, same expensive reasoning loop. Run twice, ground differently. Can't be reproduced, can't be audited, can't move to another model.

tokens to ground one agent run — less to read, because the reasoning was modeled once. (illustrative; the ~1,750 figure is the engine's real hard limit.)

03 — building the model

The reasoning model,
built once.

Building the reasoning model means doing the expensive part once. Delapan plans searches, reads sources, extracts single checkable facts, scores each one, and merges the duplicates — all live, in seconds. The result is a modeled, provenance-tracked representation of how to reason over the domain.

1 · planturn your domain into a set of sharp, targeted searches
2 · readfetch the best pages as clean text
3 · distillextract single, checkable reasoning claims
4 · modelscore, merge, and graph into a reusable structure

Each item in the model is one claim, one source, one confidence score. It reads a whole page to write a single sentence — so the cost of modeling is paid once, not every time an agent runs.

what it learned
YC's Summer 2026 partner Tom Blomfield says the blocker to AI automation "is no longer the models… now the blocker is the domain knowledge," and asks for a system that "pulls knowledge out of fragmented sources, structures it, keeps it current" — "a living map of how a company actually works."

model a whole domain in one session

Tell it what you're working on, and it plans a whole library of knowledge bases, shows you the plan, and — once you say go — builds the reasoning model across all of them at once. One real session went from empty to 5 modeled knowledge bases in about two minutes.

04 — plug it in

One model.
Every agent inherits it.

Modeled once, the same reasoning injects everywhere — your coding assistant and your deployed product inherit the exact same grounding, reproducible on every call.

In your editor

Every message to your coding assistant already carries the modeled reasoning, quietly, in the background. You don't lift a finger — and the model deepens as the domain grows.

In your product

Publish it as a simple API behind your own key. One request gives your app a ready-to-inject reasoning context to drop straight into its prompt — same grounding every call.

05 — why it's leverage

Modeled once.
Read back cheap, everywhere.

The leverage is in what gets amortized: the expensive part — exploring the domain, understanding its structure, deriving how to reason over it — happens once. Every agent after that reads a cheap lookup. The cost is fixed; the reuse compounds.

1× model → ∞ agents

Whether one agent or a hundred tap the model, each reads the same cheap lookup. Modeling cost is fixed; reuse is free at scale.

provenance, not paste

Outputs cite the exact model items they used by ID — the reasoning is traceable, replayable, and auditable without bloating the prompt.

pay once

The modeling cost is a one-time write. Every agent run after that is a read — and reads stay cheap no matter how deep the model grows.

◌ the whole idea, in one line

Pay once to model it. Inject it everywhere, reproducibly. That's how modeled reasoning ends up cheaper — and more trustworthy — than re-deriving from scratch.

cost per agent run, normalized to re-derive baseline. model build amortizes across all future runs — delapan reaches steady-state around run 10.

06 — where it fits

What Delapan is not.

Not a memory layer. Mem0 / Zep / Cognee store facts the agent still has to reason over. Delapan stores the reasoning itself — cheap to read and already structured.
Not a vector database. Pinecone holds embeddings; it doesn't model reasoning, reproduce it, or make it auditable. Delapan makes the thing you'd store in one.
Not a RAG toolkit. Frameworks like LangChain are parts you assemble. Delapan models the reasoning end-to-end and keeps it reproducible — it's a finished product, not a library.
Not another AI model. It doesn't compete with Claude or GPT — it hands them a reproducible reasoning model they inherit. Works with whichever one you like.

Give your agents reasoning
they can reuse.
