What OLMo-2-1124-SFT is

OLMo-2-1124-7B-SFT NOTE: 1/3/2025 UPDATE: Upon the initial release of OLMo-2 models, we realized the post-trained models did not share the pre-tokenization logic that the base models use. As a result, we have trained new post-trained models. The new models are available under the same names as the original models, but we have made the old models available with a postfix "-preview". See OLMo 2 Preview Post-trained Models for the colleciton of the legacy models. Release Documentation OLMo 2 7B SFT November 2024 is post-trained variant of the OLMo 2 7B November 2024 model, which has undergone supervised finetuning on an OLMo-specific variant of the Tülu 3 dataset. Tülu 3 is designed for state-of-the-art performance on a diversity of tasks in addition to chat, such as MATH, GSM8K, and IFEval. Check out the OLMo 2 paper or Tülu 3 paper for more details! OLMo is a series of Open Language Models designed to enable the science of language models. These models are trained on the Dolma dataset. We are releasing all code, checkpoints, logs (coming soon), and associated training details. The core models released in this batch include the following: Model description - Model type: A model trained on a mix of publicly available, synthetic and human-created datasets. - Language(s) (NLP): Primarily English - License: Apache 2.0 - Finetuned from model: allenai/OLMo-2-7B-1124 Model Sources - Project Page: https://allenai.org/olmo - Repositories: - Core repo (training, inference, fine-tuning etc.): https://github.com/allenai/OLMo - Evaluation code: https://github.com/allenai/olmes - Further fine-tuning code: https://github.com/allenai/open-instruct - Paper: https://arxiv.org/abs/2501.00656 - Demo: https://playground.allenai.org/ Installation OLMo 2 will be supported in the next version of Transformers, and you need to install it from the main branch using: Using the model Loading with HuggingFace To load the model with HuggingFace, use the following snippet: Chat template The chat template for our models is formatted as: Or with new lines expanded: It is embedded within the tokenizer as well, for tokenizer.applychattemplate.

Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys olmo-2-1124-sft for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (olmo-2-1124-sft below is illustrative; you get the exact model name on deployment.)

$ curl -sS https://api.axforge.ai/v1/chat/completions \
  -H "Authorization: Bearer $AXFORGE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"olmo-2-1124-sft","messages":[{"role":"user","content":"Hello"}]}'
