ChatBox

ChatBox is a cross-platform open-source desktop AI client for Windows / macOS / Linux, with a web version as well.

πŸ’‘ Quick setup: create a key on the API Keys page and paste the Host / Path / Key from the table below.

Download

chatboxai.app β€” grab the installer for your OS.

Steps

  1. Open ChatBox β†’ Settings (bottom-left)
  2. In the AI Provider dropdown choose OpenAI API
  3. Fill in:
FieldValue
API Keypk_live_xxxxxxxxxxxxxxxx
API Hosthttps://api.tokensmart.ai
API Path/v1/chat/completions
  1. In Model, type gpt-5.4 (or any model name you want)
  2. Save and start chatting

Using Claude

Change Model to claude-sonnet-4-6 or claude-opus-4-8. ChatBox sends an OpenAI chat request and Tokensmart adapts it transparently.

Tokensmart tips

  • Dedicated mobile / shared-device key: ChatBox has mobile builds, so the key is more exposed to theft. Create a ChatBox-only key with a low daily limit (e.g. $1) β€” if it leaks you revoke it immediately without affecting other tools.
  • Rapid model A/B: ChatBox's top-bar model dropdown just rewrites the model field, so with a single Tokensmart key you can flip between GPT / Claude / Gemini / DeepSeek instantly and compare answers.
  • Bind an IP allowlist: if you only use ChatBox from fixed locations (home/office), enable IP allowlist in account settings β€” even a leaked key becomes unusable from outside.

Troubleshooting

  • Empty response β€” the "Custom API Host" must include the full URL with https://
  • Streaming not working β€” enable Streaming under Settings β†’ Advanced
  • Image input unsupported β€” ChatBox has limited multimodal support; use Cherry Studio or LobeChat for images
