The reasoning layer for agents · private beta

Your agents never forget. That's the problem.

They remember the decision you reversed three weeks ago — and build on it. flmnt keeps your agents working from what's true: the current decision, the reasoning behind it, and nothing that's been left behind.

§ 01

A familiar week

Tuesday, the caching decision changed. Thursday, your agent shipped the old one.

Everything was green. The tests passed. The agent was confident — it just couldn't know the decision it built on had moved. Context windows overflow, sessions reset, and what your team settled quietly drifts from what your agents remember.

The pattern

Agents build on whatever they remember. When a settled decision changes, the old version doesn't disappear — it sits in notes, transcripts, and summaries, looking exactly as current as the new one. More context doesn't help; it's more places for the old version to live.

With flmnt

Your agents pick up each session already knowing what's current, what changed, and why. The Thursday agent gets Tuesday's reversal as the truth — and the old decision as history, never as instructions.

§ 02

Recall vs. currency

Memory tools remember what was said. flmnt knows what's true.

Most agent memory extracts facts from transcripts after the fact and retrieves whatever looks similar. That gets you recall — what was said. flmnt's agents author decisions, reasons, and reversals as they work, so it can serve what's true now.

01
Always the current decision

When a decision is replaced, flmnt serves the new one and keeps the old one as context — never as truth. Your agents stop contradicting the team.

02
Carries the why

Every decision links to the decisions that led to it. Your agent doesn't just know what was chosen — it knows what that choice was built on.

03
Learns from its own mistakes

Mistakes are first-class memory. flmnt tracks whether your agents actually stopped repeating them — and shows you.

§ 03

Measured, in the open

We built the hardest test we could. Then we published it.

A decision gets replaced with no textual tell — nothing in the words says it's dead, only the recorded relationship does. Then we ask the agent to act. Recall reads the words, and the words look current. flmnt follows the trail.

§ 02

Three moves, every step

Hold the thread. Judge what's true. Deliver only that.

The mechanism is simple to say and hard to fake: keep the record, reason over it, and hand each step exactly what it needs.

01
Hold

Keep the thread, across sessions.

flmnt follows your agents as they work and keeps what matters: decisions, reasoning, intent, mistakes. Sessions end; the thread doesn't.

persists across every session
02
Judge

A reasoning layer weighs what's true.

Instead of sending everything back into the prompt, a reasoning layer weighs what still holds, what's been replaced, and what this step actually needs.

powered by purpose-built RLMs
03
Deliver

Your agent gets only what matters.

Your agent gets a tight, current slice of the truth — about 4% of what's available, and 100% of what matters. Less noise, fewer tokens, grounded answers.

≈ 4% of context, 100% of what matters
§ 05

The inverse of noise

Most memory gets noisier as you grow. flmnt gets sharper.

Retrieval degrades with scale — more history, more near-misses, more noise. flmnt inverts it: the more your team decides, the richer the trail its reasoning works from. The thread you build today makes every future answer better.

Retrieval precision
same workspace, six weeks
week 1 · 0.610.85

Your project's history stops being something you pay to re-read and becomes the thing your agents reason from.

Flat cost. Rising precision. And a record you can show.

§ 06

Flat, by design

You pay for signal. The rest never leaves the shelf.

Because flmnt reasons before it delivers, cost per query stays flat as your project grows — while approaches that resend history climb with every doubling. The tokens flmnt doesn't send are tokens you don't pay for, and every one is counted on a live ledger inside your workspace.

What reaches your agent

On each step, flmnt weighs everything available and forwards only the slice that bears on the task. The other 98% stays on the shelf — unsent, and unbilled.

Not a black box

The thread, made legible — and provable.

See which decisions anchor your project, what changed and why, and exactly what flmnt saved you. Every event is immutable and replayable — a record you can show, not just describe.

No rip-and-replace

Bring the agents you already run.

If it can call a tool, flmnt can sit behind it — no SDK, no rewrite, no vendor's roadmap deciding yours. One shared memory, every agent current.
