BYOK: Bring Your Own Key

AI Thing does not offer paid model access or bundled credits. You choose the model. You bring the API key. You stay in control. Supported models:
  • Fast and cost-effective (Claude Haiku 3.5)
  • Balanced (Claude Sonnet 4.5)
  • High intelligence (Claude Opus 4.1)
To connect:
  1. Get an API key from Anthropic
  2. Paste the key into the field that starts with sk-ant-...

Model Settings

In Settings → Preferences, you can fine-tune how models behave:

​
Prompt Cache

Reuses common parts of a prompt to speed up responses and lower costs during long or repetitive conversations. For one-time or short queries, caching may actually be more expensive — it’s most useful when a conversation is expected to continue over many turns. Read more.

​
Output Tokens

Set the maximum length of responses. Useful for keeping outputs concise or allowing longer, more detailed answers.
Join the Waitlist for fully managed models that don’t require your own API keys.
