### Multi-Model Architecture

Volumn.ai connects to the world's leading AI providers so you can pick the model that best fits your persona's voice, latency requirements, and budget. All inference is performed server-side — your API keys are never exposed to the browser.

### Supported Models

The following models are currently available in Volumn.ai:

Steps:

1. GPT-5.5 (OpenAI) — flagship reasoning model, best for nuanced long-form content and complex persona emulation.
2. GPT-5.2 (OpenAI) — balanced performance and speed for everyday content generation.
3. Claude 4.7 (Anthropic) — excels at conversational tone, safety-conscious replies, and thread writing.
4. Claude Opus (Anthropic) — Anthropic's most capable model; ideal for high-stakes outreach and detailed analysis.
5. Gemini 3.1 Pro (Google) — strong multilingual support and long-context understanding.
6. Gemini 3 Flash Preview (Google) — ultra-low-latency model for real-time reply scoring and AutoDM.
7. Kimi K2.5 (Moonshot AI) — optimised for Chinese-language content and East-Asian market personas.
8. DeepSeek V4 (DeepSeek) — cost-efficient model with strong reasoning; great for bulk Ghost Writer tasks.

### Choosing the Right Model

You can set a default model per Persona under Context → Extra Requirements, or override it per Agent task. Faster models (Gemini 3 Flash, GPT-5.2) are recommended for high-volume automation like Reply Agent and AutoDM. More capable models (Claude Opus, GPT-5.5) are better suited for Outreach Agent and Ghost Writer where quality matters most.

Tip: Switching models does not affect your existing tasks or conversation history. You can A/B test models by duplicating a Ghost Writer task and assigning different models to each.
