The model
The model that runs a business,
not a conversation.
nallo-1 is the planning and execution model behind Nallo. It is not tuned to answer well — it is tuned to take an ordered chain of reversible actions that never breaks a rule you set.
nallo-1 · in production since Q2 2026
How it is built
Five stages, one loop.
The verifier feeds the planner.
What makes it different
Most agent models optimise for
task success. This one optimises
for not breaking your rules.
Constraint-first, not reward-first
A plan that earns more but violates your margin floor is a failed plan, not a trade-off. Constraints are checked during search, not after — so an unsafe action is never proposed in the first place.
Reversibility is a design constraint
nallo-1 will not commit a step it cannot undo or compensate. That rules out some fast paths, and it is why a bad night costs you an apology instead of a business.
Verification is continuous
Every action carries a prediction. The verifier compares it to reality and the gap becomes training signal for the next plan — nightly, on your own data, never pooled with anyone else’s.

| Markets scored | 200, continuously |
| Content languages | EN / FR / ES · DE, IT in pipeline |
| Decisions per business, per day | ~250 |

Three variants
One family, three budgets.
nallo-1
The production model. Runs the chain end to end, proposes and commits actions under your rules.
nallo-1-mini
Distilled for the high-frequency loops — bid adjustments, support triage, stock alerts. Sub-100 ms, no planning.
nallo-1-dream
The offline sibling. Runs during Nallo Dreaming with a far larger search budget, because nothing is live.
What it does not do well yet
We would rather write this
than let you discover it.
Attribution
Reallocating spend is only as good as the attribution underneath it. Post-cookie, this is our weakest input and we treat its output as a prior, not a fact.
Long-horizon credit
Knowing which decision from three weeks ago produced today’s margin is largely unsolved. Dreaming helps; it does not close the gap.
Anything physical
nallo-1 operates what it can reach through an integration. Logistics, manufacturing and anything requiring a human signature stay yours.
