What Giotto launched
Giotto launched the Giotto family of models on 27 October 2026, unveiling Giotto Alto and Giotto Solo. The Lausanne-based company, an EPFL spinout founded in 2017, bills the pair as 'the smartest European sovereign AI models on the market.'
Alto is the flagship, positioned for advanced reasoning and free for everyone through web and mobile apps, with servers located in Europe. Solo is designed to run on a single GPU for organizations that want on-premise AI, with GPU-count-based licensing.
The sovereign angle
Sovereign AI is the framing Giotto is selling: models hosted and, for Solo, run entirely in Europe, so data does not travel to US clouds. The company says Alto runs on eight Nvidia B300s and is available from the App Store and Google Play.
The pitch lands in a broader European push for sovereign AI infrastructure, alongside Aleph Alpha's open-weight German model and Microsoft's sovereign cloud offerings. Giotto's differentiator is free public access plus an on-prem single-GPU option for organizations that need data control.
The claimed benchmarks
Giotto published benchmark tables comparing Alto and Solo with models from OpenAI, Anthropic, Google, Moonshot AI and Mistral, including a claimed 100% AIME 2026 score for Alto. These figures are entirely the company's own and have not been independently verified.
explainx, which analyzed the launch, categorized what is confirmed (the launch happened, the company and its partners exist) versus what is not (the benchmark scores). The same caveat applies to Giotto's claims about beating Google's Gemma 4 31B on a single GPU.
What it means
If Giotto's claims hold, the release would be a significant step for European sovereign AI, showing a small lab can produce frontier-adjacent reasoning models with a privacy and data-residency story. If they do not, the launch is still notable for the product structure: free flagship access plus an on-prem single-GPU tier.
Sovereign AI is becoming a competitive category, and Giotto is entering it with a consumer-friendly free tier rather than only selling to governments, which distinguishes it from some other European AI efforts.
What to watch
Watch for independent benchmark runs of Alto and Solo, which will settle whether the claimed scores are real.
Watch whether Solo gains adoption in European and Swiss organizations that need on-prem inference without sending data to US clouds.
Early independent verification and adoption will separate a genuine breakthrough from an impressive announcement.
Watch whether independent benchmarks and user testing validate Alto and Solo, and whether free access converts into a sustainable business.
Watch how European institutions respond: if Giotto can show competitive sovereign models with EU/Swiss hosting, it could become a reference point for procurement decisions that other European labs will have to match.
Early independent verification and adoption will separate a genuine breakthrough from an impressive announcement.
The company
Giotto was founded in 2017 by EPFL alumni and previously ran a paid model service; the October launch moves it to a consumer-facing free tier plus an enterprise on-prem option. The team placed second among roughly 1,500 teams at ARC-AGI in 2025, which the company cites as evidence of its research capability.
The Lausanne location and Swiss base are part of the sovereign story: Giotto explicitly frames its hosting and licensing as ways to keep European data off US clouds, and Solo's GPU-count-based licensing is aimed at organizations that want to control where inference happens.
The market context
Sovereign AI is one of the fastest-growing categories in European technology policy and industry. Governments want models they can run locally or regionally, and startups like Giotto, established players like Aleph Alpha and Mistral, and cloud providers are all positioning for it.
Giotto's structure — free flagship access plus an on-prem single-GPU model — fills a niche between fully open-weight releases and closed frontier labs. Whether its benchmark claims survive independent testing will determine whether it can keep that niche.
Benchmark claims worth checking
Scores like a claimed 100% on AIME 2026 for Alto are the kind of number that would place a small Swiss lab at the frontier. AIME is a contest-style dataset used widely to measure reasoning, and 100% is an attention-grabbing figure. Before treating it as real, look for the exact harness, sampling parameters and repetition that produced it.
Similarly, claims that Solo beats Google's Gemma 4 31B on a single GPU depend on which benchmarks and hardware are compared. Independent runs by third parties such as Artificial Analysis or lmarena would give the claims meaning. Until then, treat Giotto's tables as marketing with attached numbers.
Common questions
What are Giotto Alto and Solo?
Two models from Swiss lab Giotto, an EPFL spinout: Alto is a flagship reasoning model free via web and apps, Solo runs on a single GPU for on-premise use.
Is Giotto's 100% AIME claim verified?
No. The benchmark figures are the company's own and have not been independently verified.
