Your AI keeps
forgetting what
you already paid for.

The Harness makes every call leaner. Cerebrum remembers every solution, so your team stops paying twice for the same work.

4 developers, around the clock, for $800 a month. That used to be one developer's bill.

The corePHP story

One developer. $3,500 a month, down to $200.

Building around the clock. Never hitting the limit.

Before $3,500/mo usage-based, and climbing
After $200/mo flat plan, never maxed out

The Harness trims every call and Cerebrum keeps every answer, so the token count fell far enough to move onto a $200 flat plan. Same developer, more output, no ceiling. Not magic. coreCerebrum.

And it scaled. Four developers now build full time, around the clock, for $800 a month, total.

The leak

You are paying for the same answers on a loop.

01

Solved once, paid for again.

A hard problem gets worked out, then billed in full on every request that touches it again. The answer was never kept.

02

Built-in caching forgets in minutes.

Provider caches expire fast and serve one user at a time. Nothing carries across your team, and nothing lasts past the session.

03

Every prompt carries dead weight.

Requests go out padded with tokens the model does not need to read the task. You are billed for the padding, every call.

How it works

Trim the call. Keep the answer. Serve it free.

1

Harness trims the request

Dead-weight tokens come off before the call leaves.

every call goes out smaller
2

Cerebrum captures the answer

The hard solve is stored the first time it is worked out.

paid for once, kept forever
3

Reuse served from memory

The next time the work comes up, it comes back from memory.

that call is free
4

One solve, whole team

One person's answer becomes everyone's, on every reuse.

5

The meter shows it live

Tokens routed, tokens avoided, percent reduction, as it happens.

The old bill climbs in a straight line. Yours bends and flattens.

Aren't you just like the others?

They make each call cheaper.
We stop you paying for the same answer twice.

Run both, they stack. Caching trims a slice off every request you send. coreCerebrum remembers the answer, so the same request never has to run again. One makes each call cheaper. The other makes the repeats stop.

The memory is the moat

The savings pay for it. The memory is why you keep it.

Cheaper tokens are why teams try coreCerebrum. The memory that builds up, your fixes, your conventions, your team's best answers, is why they never turn it off.

MEMORY SHARED · PERMANENT Eng Design QA PM Ops New hire

One solve becomes the whole team's.

When anyone works out a hard problem, the answer lands in shared memory. From then on the whole organization has it, at no extra token cost. That is the part a raw subscription cannot give you.

Your best developer's answer becomes the team default.

The solve that took your strongest engineer an afternoon is there for everyone the next time, at no extra token cost.

New hires inherit your conventions on day one.

The way your team does things is already in memory. People start inside your standards instead of guessing at them.

Known bugs do not come back.

A fix, once recorded, holds. The same mistake stops being rediscovered and re-billed across the team.

Conventions hold as you grow.

Consistency does not degrade with headcount. The memory keeps a growing team pointed the same direction.

On a $20-$200/mo plan?

Stop hitting limits. Then stop paying for them.

The first win is headroom: do 3-5x more inside the plan you already pay for and hit rate limits far less. The next win is the invoice. As reuse takes over the repeat work, many teams move down to a cheaper tier without running out. That is exactly what we did at corePHP.

The guarantee

If your first paid month does not show at least a 20% drop in tokens-per-task, that month is free.

  • Measured as tokens-per-task against your trial baseline.
  • Verified from gateway logs you can reconcile against your own provider console.
  • Applied automatically as a credit. No claims process, nothing to file.
  • Per-task basis, so growing usage never disqualifies you.

FAQ

The questions buyers actually ask.

I pay discounted or reseller rates. Do your numbers still apply?

We count tokens, not dollars. The percentages hold at any rate, because a token you never spend is a token you never spend, whatever you were paying for it.

We already cache. What is left to gain?

Cerebrum stacks on top of caching. The trial shows only the incremental savings, on your own traffic, with your cache left in place.

How do you define an active user?

Any seat that routed a call that month. A seat that sat idle is $0. You are billed for use, not for headcount.

Is our data safe?

Your keys, your accounts, your infra. We never see or resell your tokens, and the engine runs inside your own boundary.

What models can we use?

Claude, ChatGPT, and Gemini. Mix them and switch anytime. Nothing about the memory is tied to one provider.

What exactly triggers the guarantee?

Under a 20% tokens-per-task reduction in your first paid month means that month is credited, automatically. No claim to file.
