Adapting LLMs to Hebrew: Unveiling DictaLM 2.0 with Enhanced Vocabulary and Instruction Capabilities
The DictaLM-2.0-Instruct Large Language Model (LLM) is an instruct fine-tuned version of the DictaLM-2.0 generative model using a variety of conversation datasets.
For full details of this model please read our release blog post or the technical report.
This is the instruct-tuned full-precision model designed for chat. You can try the model out on a live demo here.
You can view and access the full collection of base/instruct unquantized/quantized versions of DictaLM-2.0 here.
Instruction format
In order to leverage instruction fine-tuning, your prompt should be surrounded by [INST] and [/INST] tokens. The very first instruction should begin with a begin of sentence id. The next instructions should not. The assistant generation will be ended by the end-of-sentence token id.
E.g.
text = """<s>[INST] 讗讬讝讛 专讜讟讘 讗讛讜讘 注诇讬讱? [/INST]
讟讜讘, 讗谞讬 讚讬 诪讞讘讘 讻诪讛 讟讬驻讜转 诪讬抓 诇讬诪讜谉 住讞讜讟 讟专讬. 讝讛 诪讜住讬祝 讘讚讬讜拽 讗转 讛讻诪讜转 讛谞讻讜谞讛 砖诇 讟注诐 讞诪爪诪抓 诇讻诇 诪讛 砖讗谞讬 诪讘砖诇 讘诪讟讘讞!</s>[INST] 讛讗诐 讬砖 诇讱 诪转讻讜谞讬诐 诇诪讬讜谞讝? [/INST]"

Model Architecture
DictaLM-2.0-Instruct follows the Zephyr-7B-beta recipe for fine-tuning an instruct model, with an extended instruct dataset for Hebrew.
Limitations
The DictaLM 2.0 Instruct model is a demonstration that the base model can be fine-tuned to achieve compelling performance. It does not have any moderation mechanisms. We're looking forward to engaging with the community on ways to make the model finely respect guardrails, allowing for deployment in environments requiring moderated outputs.
