Most AI tools give you one assistant and expect it to do everything. PingModel takes a different approach. @mention the model you need, compare perspectives side by side, and make decisions with better signal — all in one workspace. PingModel is BYOK (bring your own key). You connect your own provider keys, choose your own models, and keep full control over cost and access. Nothing is routed through us. > How It Works - @mention any bot: Ping the model you need by name. No menus, no mode switching — just @mention a bot in a channel and it answers your query. - Simultaneous mode: All bots reply to the same query at once. Compare reasoning, tone, and accuracy across models in a single glance. - Collaboration mode: Bots respond one after another, each building on the conversation. One model drafts, another critiques, a third refines. > Workspace Features - Multi-bot channels: Talk with multiple model-backed bots in a single conversation. - Threaded discussions: Keep deep dives separate while preserving context in the main timeline. - Per-bot configuration: Set model, handle, temperature, and system prompt so every bot carries a distinct role. - Channel system prompts: Define stable instructions that carry into both channel and thread replies. - Context controls: Choose full history when continuity matters, or limit to the last N messages for faster, tighter responses. - Provider management: Configure providers and custom endpoints with full flexibility. - iOS-native experience: Fast, polished interface built for daily use. > Supported Providers OpenRouter · OpenAI · Anthropic · Azure OpenAI · Cerebras · DeepSeek · Google AI · Groq · Mistral AI · Ollama · Perplexity · xAI · Kimi · Z.AI · Zhipu · MiniMax · and any OpenAI-compatible endpoint. PingModel helps you compare perspectives, reduce noise, and choose better answers — all from one workspace.
