Mini
Fast and light. Answers arrive about as quickly as you can read them.

Everyday questions, quick rewrites, short summaries, translation.
The model
Firas AI
Our first model family, and the engine under everything we ship. It reads, reasons and writes in Arabic and English natively — not through a translation layer bolted on at the end.
How it is built
One model family, four depths
Rather than four unrelated models, Firas AI is a single family trained together. Each engine is the same mind given a different amount of time to think.
Arabic in the foundation
Arabic is present from pre-training onward, not appended as a fine-tune. Dialect, diacritics and right-to-left structure are handled as first-class cases, never as edge cases.
Reasoning you can inspect
On the deeper engines the model works a problem through in steps before it answers, and it will show you those steps whenever you ask for them.
Grounded, not guessed
When an answer depends on a document or on the live web, Firas AI cites where it came from. If it cannot ground a claim, it says so instead of inventing one.
One surface, four tools
The same model powers chat, the agent, the code environment and your document library — so context carries across all four without you re-explaining yourself.
Engines
Four engines, one account
Pick the depth your task needs — from instant answers to the hardest, most demanding work.
Balanced
Pro
The default. Strong reasoning for most writing, analysis and code.
Best for
Drafting, research, debugging, everyday professional work.
Advanced
Ultra
Deeper reasoning for complex, multi-step work that has to hold together.
Best for
Long documents, architecture decisions, multi-file code, analysis.
Deepest
Max
The most capable engine. It takes its time, and it checks its own work.
Best for
The hardest tasks, where being right matters more than being fast.
Side by side
Which engine, and when
The same model at four depths. This table is the whole difference.
| Engine | Mini | Pro | Ultra | Max |
|---|---|---|---|---|
| Answer speed | Instant | Fast | Considered | Deliberate |
| Reasoning depth | Direct | Solid | Multi-step | Deepest |
| Shows its steps | — | On request | Yes | Yes |
| Checks its own work | — | — | Yes | Always |
| Long documents | Short only | Good | Strong | Strongest |
| Multi-file code | — | Good | Strong | Strongest |

MentronX internal evaluation, August 2026. Scores are normalised to 100 and run on our own task suite; independently run results will differ. We publish the suite alongside every model update.
The gap is widest where it matters most to us
On Arabic reasoning the distance is not close — that is the whole point of building this here rather than importing it. On the general benchmarks Firas AI Max holds its own against models trained with far more compute.
The machine
Look it in the eye.
Everything MentronX builds is meant to be met halfway. This one follows your hand, turns as you scroll, and does nothing else — which is roughly the point.
Questions
Common questions
A model family and the platform built on it: chat, an autonomous agent, a development environment in the browser, and a library that answers from your own documents — all under one account.
How much thinking you get per answer. Mini is instant, Pro is the balanced default, Ultra handles complex multi-step work, and Max is the deepest engine for tasks where being right matters more than being fast. You can switch engine in the middle of a conversation.
It answers in whatever language you write — Arabic, English, or both in one sentence. Arabic is not an afterthought here: it was built into the model from the start.
In any browser, at firasai.org. There is nothing to install and nothing to keep updated.
No. Your documents and conversations belong to your account, and deleting them removes them.

One account. Four tools. Four engines. Arabic first.
