Everyone rents intelligence by the token. What if you owned the whole stack?

Run any open-weight model on your own hardware. Give it memory, tune it, evaluate it, serve it fast, or build your own. An open stack that moves at the speed of open source.

The Default Nobody Questions

The frontier API is the default. For most work, it is the wrong one.

Every call leaves your walls, bills you by the token, and ties you to one vendor. For the bulk of enterprise work, none of that is necessary.

YOUR WALLS Your workload records, data, context your data $ per token Frontier API metered, external, out of your control
01

The meter never stops

You pay per token, on every call, forever. The bill grows with your success.

02

Your data leaves the building

Every request ships your context to someone else's servers to be processed.

03

One vendor owns the dial

Price, access, rate limits, and the model itself can change without your say.

Why Now

Two things crossed at once. The models got good, and the tooling grew up

Small open-weight language models now clear the bar for most work. And the open tools around them, serving, memory, tuning, and evaluation, matured into a full stack you can actually own.

Good enough for most work Small language models Open tooling Earlier Each open generation
Directional illustration. The shape of the trend, not measured values.
01

The models cleared the bar

For classification, extraction, routing, drafting, and more, a hosted small model is enough.

02

The tooling became a stack

Serving, memory, tuning, and evaluation are now open building blocks, not research demos.

03

You move at the speed of open

A better open model or tool lands every few weeks. You adopt it when you choose.

Arjun Jaggi · AI Solutions Engineering03
The Strategy

Hybrid by design. Local for the heavy lifting, frontier when you must

The question is not open versus closed. It is which workload runs where. Most of it can run local. A thin slice genuinely needs the frontier.

Data sensitivity → higher
Local
Sensitive, routine. Keep it in your walls.
Local, tuned
Sensitive and hard. Adapt a local model, never send it out.
Local
Routine, low stakes. The clear home for open-weight models.
Frontier, selectively
Hard, and safe to send out. The thin slice worth renting.
Task difficulty → harder
One rule decides it.

Keep the work local unless it is genuinely beyond a local model and the data is safe to send out. Sensitive data stays home no matter how hard the task.

Three corners stay local. One is worth the frontier.

The Open Stack

One harness runs any open model. Everything you need sits on top of it

A harness engineering layer runs any open-weight model you choose, with memory, tuning, evaluation, serving, and a research agent built around it. One such open stack is Zorp. All of it inside your walls.

YOUR WALLS, OFFLINE Memory ZorpMem Adapt fine-tune, RLStudio Evaluate BudgetBench Serve fast inference Investigate research agent Harness engineering layer Zorp, a harness and CLI that runs any open model The model any open-weight model, or one you build Your hardware Frontier WHEN YOU MUST
Own the whole stack, on your own infrastructure. Run any open model or build your own, and reach for the frontier only for the thin slice that needs it.

The Open-Source Case

You are not buying a model. You are owning an interchangeable stack

The harness runs any open-weight model, so the model is a part you can swap, not a vendor you are married to. When a better one ships, you drop it in. Nothing else changes.

Open model A Open model B Your own model ANY WEIGHTS, SWAPPABLE The harnessone interface Your appunchanged
01

No lock-in

The model is a component. Swap it for a better one without touching the app around it.

02

Open and inspectable

Open weights mean you can see, test, and change the model, not just call it blind.

03

A CLI for the people who build

The harness ships as a command line interface and API, the way developers, researchers, and scientists actually work.

Arjun Jaggi · AI Solutions Engineering06
The Memory Layer

Give it a memory that stays home

A model with no memory starts cold every time. A memory layer keeps your documents, history, and working context on your hardware and feeds them to the model when it needs them. One such layer is ZorpMem.

YOUR WALLS Model open-weight ZorpMem the memory layer documents, history, working context NOTHING LEAVES
01

Context that persists

The model stops starting cold. It carries what you have already told it, call to call.

02

Your knowledge, in your walls

Documents and history stay on your hardware and feed the model only when it needs them.

03

The memory never leaves

The context that makes answers useful is never shipped to a vendor to be stored.

Arjun Jaggi · AI Solutions Engineering07
Make It Yours

Use it, adapt it, or build your own. On your hardware, every step

Owning the stack means you are not stuck at any rung. Run an open model as is, fine-tune and post-train it on your data, or go all the way and pre-train your own. The ladder is yours to climb.

RUN

Use an open model

Pick an open-weight model and run it as is. The fastest path, and enough for most work.

ADAPT

Fine-tune and post-train

Tune it on your data, and shape behavior with reinforcement post-training through RLStudio.

BUILD

Pre-train your own

When the work demands it, pre-train a model of your own. The stack is built to take you there.

Data stays in

Every rung runs on your hardware, so the data that adapts or builds the model never leaves your walls to do it.

Prove It Holds Up

A leaderboard will not tell you if a small model clears your bar

A model that looks strong in a benchmark can fall over inside your token, context, and memory budget. Test it the way you will run it, under the limits you actually have.

On the leaderboard Under your budget Large model A Mid model B Small model C Small model C Mid model B Large model A
Directional illustration. Rank once real budget limits apply, not measured values.
01

Fix the budget first

Token, context, and memory limits are the test conditions, not an afterthought.

02

Rank can invert

The leaderboard leader can lose to a smaller model once the budget bites.

03

Measure on your tasks

Your data and your bar, under your limits, not a public average.

Budget-tiered evaluation is formalized in BudgetBench (Rao and Jaggi, arXiv 2609.13149).

Serve It Fast

Local does not mean slow. Tuned inference is fast and cheap to run

The same open model, served well, is close and inexpensive. Quantization, batching, and caching turn hardware you already own into a responsive endpoint.

Cost per run Frontier API Tuned local Response latency Round trip to a data center Local, in your walls
Directional illustration. Relative cost and latency, not measured values.
01

Quantize

A smaller numerical format fits the model on commodity hardware and speeds every call.

02

Batch and cache

Group requests and reuse repeated context, so throughput climbs and cost per run falls.

03

No round trip

The model sits next to your work. No hop to someone else's data center for every call.

Arjun Jaggi · AI Solutions Engineering10
Agentic Security

An agent you run offline cannot leak what it never sends

The strongest control on an agent is where it runs. On your own infrastructure, offline, its reach is bounded by your walls, its actions are logged, and its data has nowhere to go.

YOUR WALLS, OFFLINE Agent scoped reach Files, allowed Database, allowed Internet, blocked NOTHING LEAVES YOUR WALLS
01

Bounded blast radius

The agent can only reach what your own infrastructure chooses to expose to it.

02

Scoped permissions

It touches the tools and the data you allow, and nothing beyond that.

03

A logged trail

Every action and tool call is recorded, so no step the agent takes is unaccountable.

04

Nothing exfiltrates

Offline by default, so prompts and data cannot leave to an external service.

For the Answers That Must Hold Up

Stop asking for an answer. Ask for an investigation

A local model gives you an answer. It does not make it defensible. For the questions that have to hold up, the stack includes a research agent that keeps a record as it goes.

A prompt
Nothing kept
Question Answer

Fluent in seconds. It will not tell you whether to believe it, or what it found that pointed the other way.

An investigation
A record to answer to
Question› Registered intent› Sources› Evidence› Checkpoint› Answer

Every claim in the answer traces back to the record. It is checkable by someone who was not there.

Answers are cheap. Evidence is not.
Arjun Jaggi · AI Solutions Engineering12
Commit Before You Look

Say what would prove you wrong, before any evidence exists

Before the agent gathers anything, it commits the hypothesis, the metric, and a kill threshold to a human-readable, hash-verified record. A run cannot quietly rewrite what it set out to test.

hypothesis metric threshold committed and hashed, before any evidence exists kill threshold attempt 1 within threshold recorded attempt 2 conflicts with attempt 1 recorded anyway attempt 3 crosses the threshold KILLED. The record says why.
!

The kill threshold

A number, set in advance, that says what would prove the hypothesis wrong.

Who holds the line

The agent never proposes the threshold. A human does, and only a human can move it. Every attempt is recorded, and when a run crosses the line, the record says why.

Arjun Jaggi · AI Solutions Engineering13
What the Answer Is Accountable To

Every claim resolves to a row, not a paragraph

Each investigation writes to a six-part evidence record. Measurements are typed values, not narrative, so a claim in the report resolves to a stored row rather than to a paragraph the model wrote about itself.

tracks the parent table preregistrations Committed hypothesis and threshold, hash-sealed. experiments Every attempt, including the one that ended the run. metrics Typed values, such as accuracy 0.87, not prose. checkpoints Each human yes or no, and when. validations Redundancy and feasibility, each with its citation.
Tracks is one investigation. Every claim in the report resolves to a row in one of these tables, checkable by someone who was not there.
Arjun Jaggi · AI Solutions Engineering14
The Human Is the Author of Record

Four capabilities, one loop, a human gate before each

Validate, investigate, co-write, and deliver. A human checkpoint sits between every step, because a research checkpoint has no safe default. The models can run entirely local, so nothing leaves the machine.

● HUMAN GATE
01Validate

Is the question worth investigating. Scored on redundancy and feasibility, each must cite evidence or score zero.

● HUMAN GATE
02Investigate

Gather evidence through staged, pre-registered attempts. One attempt per step, so each surfaces at a checkpoint.

● HUMAN GATE
03Co-write

Draft the artifact from the record. The model is handed only what was recorded, and cites only those figures.

● HUMAN GATE
04Deliver

Match the finished artifact to the right format and audience.

The author of record

The model drafts, but a human approves every step and signs the result. The human is always the author of record, never the agent.

What You Get Back

Own it once. Stop paying to think, and set your own pace

The frontier meter runs forever. An open stack is an asset you own, and it moves as fast as you choose to move it.

Payback Rent. Per token, forever. Own. Set up once, then run. Day one Cumulative cost over time
Directional illustration. The shape of the economics, not measured values.
01

Cost

From a meter that never stops to an asset you own and run at the cost of power.

02

Sovereignty

Your data, context, and memory stay inside your walls. Run it fully offline, on your own infrastructure.

03

Control

You choose the model and when it changes, on your schedule, not a vendor's.

04

Speed

Adopt every open advance the day it lands. You move at the speed of the whole community.

Arjun Jaggi · AI Solutions Engineering16
The One Move

Move one heavy workload onto the open stack. Measure it.

Do not boil the ocean. Pick a single high-volume workload, run it on an open model through your own stack, and compare on cost, quality, and data exposure.

01

Pick one workload

High volume, routine, and not the hardest thing you run. A summarizer or a classifier.

02

Run it on your stack

Stand up an open model on hardware you own, and route that one workload through it.

03

Measure the gap

Compare cost per run, quality against your bar, and how much data left your walls.

What you learn

One measured workload tells you how much of your frontier spend was never necessary, and what owning the rest would be worth.
