Tripo AI 3D Generator
Mini toolsApertus 8B 2509
The model natively supports over 1800 languages and delivers long context processing up to 65,536 tokens, tool use, and agentic capabilities. Apertus stands out for its full openness: open weights, open training data, full training recipes, and compliance with data owner opt-out consent even retroactively.
On general language understanding benchmarks, Apertus 8B achieves 65.8% average across ARC, HellaSwag, WinoGrande, XNLI, XCOPA, and PIQA — comparable to Llama 3.1-8B (65.4%) while being fully open. Licensed under Apache 2.0.
Overview
Apertus 8B 2509 is a fully open 8B parameter language model by Swiss AI Initiative, pretrained on 15T tokens. It natively supports over 1800 languages including all Swiss national languages, uses only compliant open training data, and achieves performance comparable to closed-source models. Supports long context up to 65K tokens and tool use.
About Swiss AI Initiative
The Swiss AI Initiative is the world's largest open science/open source effort for AI foundation models, started in December 2023. Seeded with over 10M GPU hours on the Alps supercomputer and a 20M CHF grant from the ETH Domain, it is the first initiative of the Swiss National AI Institute—a partnership between the ETH AI Center and the EPFL AI Center—leveraging 800+ researchers (70 AI-focused professors) from 10+ Swiss academic institutions.
