--- title: PresenceAI emoji: 🎭 colorFrom: purple colorTo: blue sdk: static app_file: index.html pinned: false --- # PresenceAI PresenceAI builds **open, production-oriented conversational models** for e-commerce, social connection, and tool-calling experiences. ## Presence Muses **Presence Muses** is our first open model family: a set of LoRA adapters covering supervised fine-tuning (SFT) and direct preference optimization (DPO). The adapters are small and composable, and are designed to sit on top of well-known base models. | Model | Base model | Stage | Adapter size | |---|---|---|---:| | [Calliope-32B-SFT-LoRA-v1.0](https://huggingface.co/PresenceAI/Calliope-32B-SFT-LoRA-v1.0) | [Qwen/Qwen3-32B](https://huggingface.co/Qwen/Qwen3-32B) | SFT | 1.07 GB | | [Polyhymnia-32B-SFT-LoRA-v1.0](https://huggingface.co/PresenceAI/Polyhymnia-32B-SFT-LoRA-v1.0) | [Qwen/Qwen3-32B](https://huggingface.co/Qwen/Qwen3-32B) | SFT (full-data run) | 1.07 GB | | [Erato-27B-DPO-LoRA-v1.0](https://huggingface.co/PresenceAI/Erato-27B-DPO-LoRA-v1.0) | [Qwen/Qwen3.8-27B](https://huggingface.co/Qwen/Qwen3.8-27B) | DPO | 638 MB | | [Thalia-31B-DPO-LoRA-v1.0](https://huggingface.co/PresenceAI/Thalia-31B-DPO-LoRA-v1.0) | [Gryphe/Gemma-4-31B-StyleTune](https://huggingface.co/Gryphe/Gemma-4-31B-StyleTune) | DPO | 935 MB | ## What we release - **LoRA adapters only** — base model weights are not redistributed; download the base model separately from its upstream repository. - **No training or evaluation datasets** are published with these adapters. - Adapters are released under **Apache-2.0**; the upstream base-model licenses and terms continue to apply. - These are research and prototyping models. Evaluate quality, safety, and policy compliance for your own deployment. ## Model lineage - **Calliope / Polyhymnia** are supervised fine-tunes of `Qwen/Qwen3-32B`; Polyhymnia is the full-data run. - **Erato** is a DPO adapter trained directly on the `Qwen/Qwen3.8-27B` base model. - **Thalia** is a DPO adapter trained on `Gryphe/Gemma-4-31B-StyleTune`, a style-tuned derivative of Gemma-4-31B — not on the original Gemma base.
