BizerGPT: how it works

Chat with the latest models from OpenAI, Google, Anthropic, DeepSeek and xAI in one place, free to start and then paid per token from your Bizer wallet.

BizerGPT is a plain AI chat, like ChatGPT, where you pick the model. Open it from your apps, or go to bizer.app/app/bizer-gpt. It works on the web.

You don't need an account with OpenAI, Google, Anthropic, DeepSeek or xAI. Bizer holds those accounts, and you pay for what you use from one Bizer wallet.

Pick a model

Use the Model menu at the top. The models are grouped by company:

| Company | Models | | --- | --- | | Bizer | Bizer Free | | OpenAI | GPT-6 Astra, GPT-6.1 Sol, GPT-6 Luna | | Google | Gemini 3.1 Pro, Gemini 3.8 Flash | | Anthropic | Claude Opus 5.5, Claude Sonnet 5.5, Claude Haiku 5.5 | | DeepSeek | DeepSeek V4 Pro, DeepSeek Flash | | xAI | Grok 4.7 |

Under the menu you see what the model is good at and what it costs per million tokens. A model marked not available yet can't be picked until Bizer turns it on. You can switch models in the middle of a chat: the new model reads the conversation so far.

What it costs

• Bizer Free costs nothing until this month's free BizerGPT tokens are used.

The screen shows how many are left. They come back on the 1st of each month.

• Every other model, and Bizer Free once the free tokens are used, is paid

per token. A token is roughly three quarters of a word, counted on both your message and the reply.

• Paid replies come out of your plan's monthly budget first, then your

wallet. See What Miles costs.

• Each reply shows its tokens and what it cost.

If you add your own API key for a company (below), its models don't use any of this: you pay that company directly.

When there's nothing left to spend, BizerGPT says so before it sends anything, and nothing is charged. Tap Add funds to top up your wallet, or switch to Bizer Free if you still have free tokens.

BizerGPT's free tokens are separate from free chat with Miles. Using one never uses up the other.

Use your own API keys

Already pay OpenAI, Google, Anthropic, DeepSeek or xAI for API use? Add your own key and that company's models run on it:

1. Tap Your API keys under your chats (on a phone, tap ☰ first).
2. Paste the key for that company and tap Save. BizerGPT checks the key

with the company before saving it.

1. The company's models now show (your key) in the Model menu, and each

reply says Your key instead of a price.

Replies on your own key are billed by that company on your account with them. Nothing comes out of your Bizer wallet, your plan's budget or your free BizerGPT tokens, and Bizer's limits don't apply to them. That company's own limits and billing still do: if a reply fails, check your key and your billing with them.

Your key is kept encrypted and is never shown again, only its last four characters. Tap Remove to stop using it; that company's models go back to Bizer's key and your wallet. Deleting your Bizer account deletes your keys.

Your chats

Your chats are listed on the left (on a phone, tap ☰). Tap one to open it, search them by title, or tap × to delete one. A deleted chat can't be brought back. + New chat starts fresh.

Each reply has a Copy button.

BizerGPT and Miles

BizerGPT doesn't read your business's memory, files or connected tools, and it can't do anything for you. It only answers. When you want help with your own business, ask Miles: talking to him is free.
