Fabel5
Task authoring and evaluation against a working engineer's judgement rather than a checklist.
Services · 1.5 years+
We work with model teams.
Contractual engineering for the organisations leading the field, including Anthropic, OpenAI and Gemini. 1.5 years+ of continuous work across 4 model programmes, trained with advanced reinforcement learning techniques and reviewed against each team’s own quality bar.

Mythos
Engineering work delivered to spec, reviewed and iterated against real model behaviour.
Gemini
Continuous contribution across the programme, scaled up and down as the work required.
OpenAI
Agentic coding and tool-use work, authored and reviewed against the programme's own bar.

How an engagement runs
Four steps, no lock-in
Scope
You describe the work. We say plainly what we can take on and what we cannot.
Trial slice
A small piece delivered first, so both sides see the standard before committing.
Deliver
Continuous contribution at an agreed rate, reviewed against your own quality bar.
Scale
Widen the engagement or wind it down. No lock-in either way.
The work itself
Fabel5MythosGeminiOpenAIWhat we do
Engineering delivered under contract to model teams: the tasks that need a working engineer's judgement rather than a checklist, and the evaluation work that shows whether an output is actually better.
Who we have worked with
Over 1.5 years and counting our work has covered the Fabel5, Mythos, Gemini and OpenAI programmes, across authoring, review and evaluation.
Dataset preparation
ATC and VAD audio datasets labelled to 1 ms accuracy, object localisation in images, and video segmented by action. High-quality data, delivered ready to train on.
How to engage us
Short scoped engagements or a continuing arrangement. Tell us the shape of the work and we will say what we can take on and when.
