The models behind ChatGPT and Claude, plus 300+ more — all in one chat. Pay per use instead of stacking $20/month subscriptions: a simple question costs cents.
Why pay $20/month for ChatGPT Plus, another $20 for Claude Pro, and yet another for Gemini? On NeuralBox, all flagship models — GPT from OpenAI, Claude from Anthropic, Gemini from Google, DeepSeek, Qwen, Llama, Mistral, Grok and hundreds more — live in one chat, in your browser, on one balance.
The key difference from subscriptions is pay-per-use pricing: each request costs exactly what it costs — no flat $20/month for capped limits. A simple question to DeepSeek or Gemini Flash runs under a cent; flagship GPT and Claude answers cost a few cents to a fraction of a dollar. If you don't chat every single day, this is several times cheaper than a subscription; if you do, larger plans cut token cost by up to 40%. Tokens never expire.
You can switch models mid-conversation: start with a fast cheap model, then jump to a flagship for the hard question — context carries over. Files and images are supported (up to 10 attachments), conversation history is saved. For developers there's an OpenAI-compatible API: one key for every model.
One account — every task: from homework to code and analytics.
