Description
The website, registration, design, menu and payment system are handled separately. This role focuses only on the AI core: dialogue models, AI characters, memory, user adaptation, realistic image generation and MVP AI architecture.
Required skills
LLMs for conversational AI products.
Testing and comparing open-source and commercial models.
Llama / Hugging Face / vLLM / Text Generation Inference.
System prompts for AI characters.
Prompt engineering, fine-tuning and LoRA.
Memory layer design: mem0, Qdrant, embeddings, RAG.
Python, Docker, PostgreSQL, Redis.
GPU infrastructure and model deployment.
AI image generation: FLUX.1 / Stable Diffusion / ComfyUI.
Consistent face setup for AI characters.
Moderation / safety filters for AI dialogues.
Tasks
Select and test LLMs for romantic AI dialogues, set up AI characters, design user memory, plan adaptation to the user’s communication style, and suggest a pipeline for realistic AI selfies.
Experience with AI companions, dating, chatbots, virtual characters, roleplay scenarios or conversational AI is a plus.
The candidate should be ready to complete a short test task.
Please include your stack, relevant experience, project examples, readiness to complete the test task and your rate / estimated project cost.

I would like to know what will define success for your MVP: the most natural romantic conversations, strong long term memory, fast response time, or highly consistent AI selfies? Prioritizing this early helps choose the right LLM, memory pipeline, and infrastructure instead of optimizing the wrong thing.

Hi Alisa,
I have a few quick questions before preparing our proposal:
1. Do you already have a preferred LLM provider (open-source, OpenAI, Anthropic, etc.)?
2. Will the AI companion support text only in the initial release, or are voice and multimodal interactions planned from the start?
3. Is the GPU infrastructure already provisioned?
4. Could you share the expected timeline for the MVP and the approximate number of AI characters planned for the first release?
Looking forward.
