-## Side‑by‑Side AI — One prompt, answers from many models
-
-This Space shows Grok 4, ChatGPT (OpenAI), Gemini 2.5 Pro, DeepSeek, Claude Sonnet 4, and Perplexity Sonar Pro side‑by‑side in a single chat window. No tab‑hopping. You enter one prompt and compare answers instantly.
-
-### Live features
-- One prompt → parallel calls to selected providers
-- Models shown in columns, updated as responses arrive
-- Optional system prompt, temperature, and per‑provider model names
-- Works with API keys set as **Space Secrets** (recommended) or typed at runtime
-- Clean, mobile‑friendly Gradio UI
-
-### Supported providers
-- **OpenAI** (e.g., `gpt-4o`, `o4-mini`, etc.)
-- **Anthropic** (Claude Sonnet 3.7/4, etc.)
-- **Google Gemini** (e.g., `gemini-2.0-pro`, `gemini-2.0-flash`)  
-- **xAI Grok** (via OpenAI‑compatible API, e.g., `grok-2-latest`)
-- **DeepSeek** (`deepseek-chat`) via OpenAI‑compatible API
-- **Perplexity** (`sonar-pro`) via OpenAI‑compatible API
-
-> You can enable or disable any provider from the sidebar.
-
-### How to run on Hugging Face Spaces
-1. Create a **Gradio** Space. 
-2. Add these files (`app.py`, `requirements.txt`, optional `Procfile`).
-3. In **Settings → Secrets**, add any keys you have (you don’t need all of them):
-   - `OPENAI_API_KEY`
-   - `ANTHROPIC_API_KEY`
-   - `GEMINI_API_KEY`
-   - `XAI_API_KEY` (Grok)
-   - `DEEPSEEK_API_KEY`
-   - `PPLX_API_KEY` (Perplexity)
-4. Deploy. The app auto‑detects which providers have keys.
-
-### Notes
-- Some providers have usage limits and content rules. Your account is responsible for API costs.
-- If a provider is missing a key, its column will show a helpful message instead of failing.
-- Perplexity supports retrieval/web by default; this app sends plain prompts. You can add custom params in code if you need web search.
