extra_gated_prompt: "### Apertus LLM Acceptable Use Policy  \n(1.0 | September 1,
  2025)\n\"Agreement\" The Swiss National AI Institute (SNAI) is a partnership between
  the two Swiss Federal Institutes of Technology, ETH Zurich and EPFL. \n\nBy using
  the Apertus LLM you agree to indemnify, defend, and hold harmless ETH Zurich and
  EPFL against any third-party claims arising from your use of Apertus LLM. \n\nThe
  training data and the Apertus LLM may contain or generate information that directly
  or indirectly refers to an identifiable individual (Personal Data). You process
  Personal Data as independent controller in accordance with applicable data protection
  law. SNAI will regularly provide a file with hash values for download which you
  can apply as an output filter to your use of our Apertus LLM. The file reflects
  data protection deletion requests which have been addressed to SNAI as the developer
  of the Apertus LLM. It allows you to remove Personal Data contained in the model
  output. We strongly advise downloading and applying this output filter from SNAI
  every six months following the release of the model.  "

***For a convenient overview and download list, visit our [model page for this model](https://hf.tst.eu/model#Apertus-8B-Instruct-2509-GGUF).***

weighted/imatrix quants are available at https://huggingface.co/mradermacher/Apertus-8B-Instruct-2509-i1-GGUF
## Usage

If you are unsure how to use GGUF files, refer to one of [TheBloke's
READMEs](https://huggingface.co/TheBloke/KafkaLM-70B-German-V0.1-GGUF) for
more details, including on how to concatenate multi-part files.

## Provided Quants

(sorted by size, not necessarily quality. IQ-quants are often preferable over similar sized non-IQ quants)
