TW3Cast, 3rd out of 130 on the GIFT-Eval benchmark
For each series to be forecast, TW3Cast picks the best suited of three open models (Chronos-2, TiRex, Toto). The code and selection rules are public.

Research programme
Our research areas
Interface agents
4 topicsOur agents locate the elements on a screen to click and type in place of a person, including in software with no API.
Time-series forecasting
5 topicsWe adapt large open models to forecasting, energy production in particular, and test them on data they have never seen.
Document understanding
12 topicsOur models treat each page as an image, diagrams, tables, scans and manuscripts included, and find the right page among thousands.
Visibility in AI engines
13 topicsWe study how AI engines choose the sources they cite, and have published a content score whose resistance to manipulation we measure.
Multi-agent systems
26 topicsWe work on how teams of agents cooperate in production, and on checking what an agent claims to have done.
Document production agents
11 topicsWe study where agents that write reports, spreadsheets and presentations go wrong, and how to measure the quality of what they deliver.
Model safety
11 topicsWe train small guardrail models that an organisation can host and control itself.
Model specialisation
12 topicsWe specialise open models so that a small model is enough for a specific task: query routing, reinforcement learning, domain adaptation.
AI for education
4 topicsWe measure what an assistant grounded in the institution's own courses adds over a general-purpose model, and design tutors that guide students without giving them the answer.
Office software in the browser
5 topicsWe rebuild in the browser the layout of a word processor and the functions of a spreadsheet, and measure how close we come to Word and Excel.
