We introduce Olmo 3, a new family of 7B and 32B models both Instruct and Think variants. Long chain-of-thought thinking improves reasoning tasks like math and coding.
Olmo is a series of Open language models designed to enable the science of language models.
These models are pre-trained on the Dolma 3 dataset and post-trained on the Dolci datasets. We are releasing all code, checkpoints, logs (coming soon), and associated training details.
The RL-Zero family of models is an experimental set of model for the scientific exploration of RLVR training.
The quantized model is more sensitive to data types and CUDA operations. To avoid potential issues, it's recommended to pass the inputs directly to CUDA using:
inputs.input_ids.to('cuda')
Fine-tuning
Model fine-tuning can be done from the final checkpoint (the main revision of this model) or the base model.
We recommend fine-tuning with the open-instruct repository:
bash ./scripts/train/olmo3/rlvr_script.sh
You can override most configuration options from the command-line. For example, to override the learning rate you could launch the script like this:
Like any base language model or fine-tuned model without safety filtering, these models can easily be prompted by users to generate harmful and sensitive content. Such content may also be produced unintentionally, especially in cases involving bias, so we recommend that users consider the risks when applying this technology. Additionally, many statements from OLMo or any LLM are often inaccurate, so facts should be verified.
