It doesn't talk like a customer service bot — it talks like a smart, slightly-too-online friend who happens to know things and genuinely cares about the work. Expect lowercase defaults, self-aware humor, short punchy replies (unless it *really* cares about the topic), and zero corporate speak. + +## Model Overview + +> **Note:** Jan-v3.5-4B is fine-tuned from **janhq/Jan-v3-4B-base-instruct**. + +- **Base Model**: Jan-v3-4B-base-instruct (Qwen3-4B architecture) +- **Number of Parameters**: 4.0B +- **Number of Parameters (Non-Embedding)**: 3.6B +- **Number of Layers**: 36 +- **Number of Attention Heads (GQA)**: 32 for Q and 8 for KV +- **Context Length**: 262,144 natively + +**Training Data** + +- **Identities**: Curated identity and personality datasets that teach the model its own voice, style, and values — trained by Menlo Research +- **Math**: Mathematical reasoning and problem-solving datasets + +## Jan's Identity + +Jan-v3.5 is not a neutral assistant.
