Jais-3 is an open-weight IFM model family built for transparent foundation-model research, staged checkpoint analysis, and practical deployment. The series spans compact dense models for local experimentation, dense mid-size and large models for high-quality research workloads, and mixture-of-expert (MoE) models for higher-capacity serving. ## Launch Commands ```bash vllm serve IFM/Jais-3-3.7B \ --trust-remote-code \ --chat-template-content-format string \ --dtype bfloat16 \ --reasoning-parser k2_horizon \ --enable-auto-tool-choice \ --tool-call-parser k2_horizon ``` ## Client usage ```python from openai import OpenAI client = OpenAI( api_key="EMPTY", base_url="http://localhost:8000/v1", timeout=3600 ) resp = client.chat.completions.create( model="IFM/Jais-3-3.7B", messages=[{"role": "user", "content": "لدينا عددان مجموعهما 50 وحاصل ضربهما 600. ما هما العددان؟ اشرح خطوات الحل."}], temperature=1.0, top_p=0.95, max_tokens=2048, ) print(resp.choices[0].message.content) ``` ### Thinking modes The model supports selectable thinking through `chat_template_kwargs`, per request or server-wide via `--default-chat-template-kwargs`: - `{"reasoning_effort": "high"}` — full thinking (default). - `{"reasoning_effort": "low"}` — no thinking. ## References - [IFM/Jais-3-3.7B on Hugging Face](https://huggingface.co/IFM/Jais-3-3.7B) - [Jais 3 Collection](https://huggingface.co/collections/IFM/jais-3)
