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	Qwen/Qwen3-32B	SFT	1.07 GB
Polyhymnia-32B-SFT-LoRA-v1.0	Qwen/Qwen3-32B	SFT (full-data run)	1.07 GB
Erato-27B-DPO-LoRA-v1.0	Qwen/Qwen3.8-27B	DPO	638 MB
Thalia-31B-DPO-LoRA-v1.0	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.
