## Welcome to Unifically

Unifically provides a **unified API** for accessing multiple AI models including:

* **Language Models** - GPT 5.4/5.5, Claude Sonnet/Opus 4.6–4.8, Composer 2.5
* **Image Generation** - GPT Image, Nano Banana (Gemini 2.5 Flash), Flux.2
* **Video Generation** - Veo 3.1, Kling 3.0/2.6/2.1, Minimax Hailuo 2.0
* **Audio Generation** - Suno API for music and voice, ElevenLabs TTS

## For LLMs & AI Agents

Unifically publishes machine-readable docs that any LLM or coding agent can ingest directly:

* **`llms.txt`** — concise index of every page, ideal for in-context routing
* **`llms-full.txt`** — the entire documentation site as a single plain-text file
