Briefing

AI, plainly —
and what it is worth
to this estate

Twenty minutes. First, enough of the technology that we all use the same words. Then the numbers for a 1,500-unit wildlife estate.

Wildlife Estate01

Part one — the technology

A language model does one thing

Given a sequence of text, it predicts what comes next. Everything else is built on top of that.

your text
tokens
next-token probabilities
chosen token

The loop runs once per token. What people call "reasoning" is the model spending more tokens thinking before it answers.

BackgroundKarpathy, Intro to LLMs youtu.be/zjkBMFhNj_g
The prediction loop02

Part one — the technology

Four words worth knowing

Token

A chunk of text, roughly four characters. Models read, price and limit work in tokens, not words.

Context window

How much text it can hold at once. Everything it knows about your task lives there, and is gone on the next call.

Weights

The trained parameters. Open-weight models can be downloaded and run on your own hardware.

Temperature

How adventurously it picks. Low for data work and code. Higher for drafting and ideas.

Vocabulary03

Part one — the technology

What it does well, and where it breaks

Reliable

  • Transforming text you supply
  • Structure: summaries, tables, mappings
  • Writing and explaining code and scripts
  • Language, tone, translation
  • Following an explicit written procedure

Unreliable

  • Facts it was never given — it fills gaps confidently
  • Arithmetic and precise counting
  • Anything after its training cutoff
  • Your owner records, your systems, the live levy roll
  • Remembering yesterday

The right-hand column is the specification for what an agent has to solve.

An agent gives it hands, memory, and a job.

The shift05

Part one — the technology

Hermes is the loop around the model

You send a request. Hermes gives the model tools, reads the real results back, and repeats until the work is actually done.

request
model decides
tool runs
real output
model reads it

It never guesses what a script returned. It runs the script and reads the result.

The agent loop06

Part one — the technology

Four things Hermes adds

01

Tools

Files, spreadsheets, databases, scripts, web, email. How the model touches anything real.

02

Memory

Durable notes loaded every session, so what you explained once does not need explaining again.

03

Skills

Your procedures on disk, loaded only when the task matches. Your SOPs, not the model's defaults.

04

Working unattended

Scheduled and background work, so levy reminders, statements and compliance checks run overnight and are waiting in the morning.

DocsNous Research, Hermes Agent — tools, memory, skills, autonomy hermes-agent.nousresearch.com/docs
What the framework contributes07

Part one — the technology

Skills are where your expertise lives

A skill is a written procedure with a trigger. Hermes loads it only when the work calls for it.

  • The exact steps, not a paraphrase
  • The pitfalls you have already paid for
  • Your standards for that kind of work
  • Reusable by everyone, on every scheme

Why this matters here

Your value is twenty years of knowing how this scheme wants its governance run. A skill is that knowledge written down once, applied consistently, and no longer trapped in one person's head or lost when they are on leave.

DocsNous Research, Hermes Skills — procedures on disk hermes-agent.nousresearch.com
Procedural memory08

Part one — the technology

Protea — a privacy and memory layer

Protea is a privacy and memory layer, used as the example of the right architecture for regulated work. It sits between a client and any model backend, so you get the frontier model and keep the data.

Redaction — the killer feature

Named entities — people, schemes, estates, addresses — are replaced with stable placeholders before the request leaves your hardware, and restored in the reply. The model never sees an owner’s name, ID number or bank details, so you can run frontier models without an exception.

Local, one-file memory

A single SQLite file per user behind an OpenAI-compatible API. An embedded local model means it runs fully offline once the model weights are pulled. No third party ever holds your corpus.

It remembers

Structured recall across conversations and months — spiral-indexed by relevance and recency — rather than starting from nothing every session. Twenty years of knowing how this scheme runs stops living in one person's head.

And it gets your work done

Conductor routing passes each task to the model best suited for it; a confidence cascade escalates only when needed: local model for the routine, frontier model for the hard call. Consensus fans a delicate question to several models and synthesises the answer. Teams decompose a brief, rate deliverables, and review every result. An Open WebUI front-end gives clean per-user separation, with identity forwarded through the API.

The pitch to the scheme: "we run AI-assisted administration and our owners' data never leaves our environment." Very few small vendors can say that sentence truthfully.

Part one — the technology

The failure mode to design around

Asked for something it cannot know, a model produces a fluent, plausible, wrong answer rather than nothing.

How it shows up

An invented variable name. A confident number with no source. A mapping that looks right and is not.

What contains it

Read before answering, run before claiming, show the source. Grounding in real output — and a person signing off. Never autonomy over a regulated deliverable.

EvidenceNavigating the Jagged Frontier — confidence without calibration HBS 64700
Hallucination10

Part one — the technology

The experienced person is the one who makes AI safe

The evidence is not "experts get faster" — it is that expertise is what lets AI be used on the hard stuff at all.

Knows what to ask

The model cannot produce the question that only years of knowing schemes and the STSM Act produces. The value is upstream of the answer.

Catch the wrong answer

AI is fluent and confidently wrong. Inside its capability boundary it gains ~40%; pushed past it, performance drops 19 points. Only experience says where that boundary is.

Ground it in reality

The model suggests; the domain expert decides. A 19-point penalty exists precisely because it is not obvious to a generalist which tasks AI can do and which it cannot.

Turn it into procedure

A senior hand encodes their own judgement as a skill. Their expertise stops being a bottleneck and becomes repeatable.

Why a senior person wins

AI compresses the skill gap on routine tasks — a beginner with AI reaches near-expert output on well-defined work. But a scheme does not win on routine. It turns on the messy, consequential, one-off judgement where a confident wrong answer costs the scheme.

The leverage is trust, not speed

The real gain for an expert is not doing the same task faster. It is having a tireless assistant who drafts and cross-checks, while the expert spends the saved hours on the resolutions, the AGM, and the relationships no model can hold.

Part two — the numbers

The question is not whether AI is impressive.
It is how much of a R93-million-a-year estate is still run by hand.

Shifting to the numbers12

Part two — the numbers

Where the estate's hours actually go

A wildlife estate at 1,500 units with 45 employees is not a small operation. The trustees are volunteers; the staff and the administration are not.

Administered, but not by owners

59%

The share of a property team's time spent on administrative tasks. Across 45 staff that is levy statements, utility bills, reminders, minutes, quotes, compliance packs — and the same owner query answered for the hundredth time.

The load this estate carries

≈45,000 hrs

A year of administration across 45 employees — roughly 76,500 staff hours, of which the majority is the repetitive kind that never needed a person to sit through it.

That second box is the target. Not the 45 employees — the 45,000 hours of work nobody values and every owner funds.

Assumptions on slide 2115

Part two — the numbers

The gap is in the reserve fund

Annual contribution to the reserve fund, ZAR. For an estate this size, waiting is not neutral — arrears and utility-recovery failures keep eating the fund whether or not management acts.

ModelSectional Titles Schemes Management Act, Reg 2 — minimum contribution (15% of the administrative fund while the reserve is under 25%). Underfunded reserves are what turn a bad month into a special levy across 1,500 owners

Summary17

Part two — the numbers

Read the model carefully

Every scenario keeps the same 45 employees. The gain is governing 1,500 owners and R93m of their money well — not thinning the staff.

What changes

The dull half. Statements, utility reconciliation, reminders, minutes, the fourth version of the same letter, chasing the same arrear across 1,500 owners.

What does not

Fiduciary judgement. The AGM of 1,500 owners. Security decisions. Who signs off on a repudiation or a disconnect.

What grows

What the same 45 people can carry — more owners served well, more of the estate run properly, and a reason to pay them more.

An estate does not win by employing fewer people. It wins by being governed well enough that owners stop asking why levies and utilities went up.

Part three — where to point it

Inside the work you already do

Levy statements & arrears

1,500 owners: statements, the reminder ladder, the letters, the s66 or CSOS pack. The agent approves and sends.

Utility billing & recovery

R4m a month of water and electricity — metering, recovery, exceptions. The estate's single biggest cash line.

AGM & meeting packs

Notice, agenda, minutes and resolutions for 1,500 owners — first draft from last year's pack and this year's numbers.

Compliance paperwork

CSOS registration and governance documents, rule amendments, the reserve-fund plan. Rule-based and reviewable.

Maintenance & infrastructure

Roads, water reticulation, electrical. Route owner reports, chase quotes, track jobs to done. An exceptions list each morning.

Security & access control

Incident logs, access exceptions and the monthly security report — summarised for the trustees.

Insurance claims

Common-property claims: incident note, quotes, photos, the policy reference. A person signs it off.

Owner communication

Circulars, rule reminders, FAQ answers for 1,500 households — in the estate's voice, not the model's defaults.

Efficiency inside the current model19

Part three — where to point it

Services that only become affordable now

The interesting part is not doing the same work cheaper. It is what becomes possible at this scale once the marginal hour is cheap.

Utility recovery & reconciliation

Reconcile bulk water and electricity against 1,500 meters every month. At R48m a year, even 1% recovered is R480k.

Arrears early-warning

Flag the owner at 30 days, not 120 — across 1,500 accounts. Cheaper than a s66, and the difference between a blip and a crisis.

Continuous compliance

Governance documents kept current and CSOS-ready all year, instead of a scramble before the AGM.

Self-service for owners

Statements, rules, requests and answers on demand for 1,500 households. Fewer calls; the staff do the judgement work.

Reserve-fund modelling

A living maintenance and reserve plan for a large estate, updated from real spend — the STSM plan taken seriously at last.

On-premise as the pitch

Owner names, ID numbers, bank details. Local models mean the benefit without the data leaving the estate.

New scope, new markets20

Part three — where to point it

What the first ninety days look like

01

Pick the single most repetitive task — levy reminders or the monthly utility reconciliation. Time it honestly for two weeks first.

02

Write that procedure down properly as a skill. This is the real work, and it pays off even if the AI part fails.

03

Run it alongside the team for a month. Compare outputs. Keep the human sign-off permanently.

04

Measure the hours recovered and the rands recovered on utilities. That is the whole thesis — prove it on one line.

What the model assumes

1,500 units, R2,500 average monthly levy (~R45m a year), plus bulk water and electricity of ~R4m a month (~R48m a year) — about R93m administered annually. 45 employees, ~76,500 staff hours, of which 59% (≈45,000 hrs) is administration. Arrears handled at up to R15,000 per unopposed Section 66 matter.

Repetitive admin absorbed over ~4 years, releasing roughly 60% of those hours by 2031. Costs in the "do not act" path rise ~7%/yr, consistent with the survey finding that 91% of schemes face unexpected increases.

Close

The technology is ordinary. It predicts text, and a framework gives it tools and memory.

The opportunity is not. A R93-million estate, run on 45,000 hours of unpaid administration a year.

Nothing here requires betting the estate. It requires writing down how you govern, and starting.
