We train, evaluate, develop and deploy AI systems. All our services are supported by Seeweb cloud provider. We ♥ Italy and open source.
Latest work
Discover our newest model and the tools to build what comes next. Open research, made to be explored.
Our latest bilingual Italian / English model for function calling and structured output. Built on Zagreus, Nesso3 learns a compact tool contract across thousands of tool schemas, with a focus on Italian tool use.
Research-informed fine-tuning with practical defaults. Memory-efficient training, native support for agentic data, and one configuration that scales from a single GPU to multi-node clusters.
Research in focus
Meet the models and experiments behind our community. Built to be studied, shared, and taken further.
Bilingual English / Italian models designed to bring capable AI closer to the edge. Built on Zagreus, the Nesso family offers conversational instruction following, function calling, and structured output in a compact footprint.
Four bilingual foundation models, trained from scratch on around one trillion open-source tokens. Pairing English with Italian, Spanish, Portuguese, or French, Zagreus provides the foundation for Nesso—with open weights, configurations, and evaluations.
A 7-billion-parameter open model fine-tuned for fluent Italian across a wide range of domains. Maestrale brings together language generation, tool integration, structured JSON output, and reasoning capabilities.
An open research initiative exploring political bias in language models. Evaluation suites, datasets, and the Propaganda-dx and Propaganda-sx models help researchers study how political perspectives are represented and shaped.

Code & research
Full technical report for the Zagreus & Nesso SLM families — from data pipeline and pre-training to post-training and evaluation — releasing 7 open bilingual Romance language models with fully reproducible configs.
Code & research
Propaganda is an open-source initiative dedicated to assessing and generating political bias in Large Language Models (LLMs).
Code & research
We contribute to add mmlu and arc_c evaluation benchmark for Italian based tasks. Our bechmarks are now used by many LLMs groups for evaluating Italian based LLMs
Models & datasets
One of the first completely open source Italian model in three versions: continual pre-trained, SFT and DPO
Models & datasets
The entire corpus of the current Italian laws as an open source dataset
Models & datasets
Translated version of the ultrafeedback dataset for SFT fine tuning
Models & datasets
Translated version eng to ita of the popular ultrafeedback binarized dataset for DPO fine tuning.
Models & datasets
The biggest dataset of real conversations in the Italian language from usenet
Code & research
We tranlated the mmlu-pro dataset to Italian and contributed to integrate into the lm-eval command for evaluating Italian LLM on difficult tasks
Models & datasets
