FAQ

Questions, answered.

Is BlitzArt really free?+
Yes. The free tier gives you daily messages on capable models, no card required. Paid plans from $12/mo unlock frontier models like GPT-5.5 and Claude Opus, plus higher limits.

GPT-5.5, Claude Opus 4.8, Gemini 3.1 Pro, Grok 4.3, Llama, DeepSeek V4, Qwen, Kimi and 30+ more. We add new frontier models within days of release.
What does Auto do?+
Auto reads each message and routes it to the model that scores highest for that task: reasoning, coding, long context or speed. You can override it any time.
Can I switch models mid-conversation?+
Yes. Change models on any message and the full thread context carries over, so you can start with one model and finish with another.
How does this replace ChatGPT Plus or Claude Pro?+
Those each cost about $20/mo for one vendor's models. BlitzArt gives you all of them from $12/mo on one login, and you switch between them in the same thread.
