What it costs
Audio is metered separately, per million audio tokens — not added to the text rates above.
Long prompts cost more
| Prompt size | In / 1M | Out / 1M | Cache read / 1M |
|---|---|---|---|
| Up to 200K | $4 | $24 | $0.4 |
| 200K and above | $8 | $36 | $0.8 |
The band follows the size of the prompt you send.
Final AI-token prices, per million tokens. Bring your own provider key in the app to pay provider rates directly.
What it can do
Effort: high, medium and low — medium by default. More effort means more thinking tokens, billed at the output rate.

In the 00 app — pick it per agent, and per tier, then build your own agents on it. Get 00.
As a drop-in API — the same model at an OpenAI-compatible endpoint. Two settings:
- Create a workspace API key in the Overblast console — usage bills that workspace's AI tokens, at the prices on this page.
- Point your base URL at
https://brain.deployd.network/ai/v1. Chat completions with streaming, embeddings,/images,/audio/transcriptionsand/videos.
curl https://brain.deployd.network/ai/v1/chat/completions \
-H "Authorization: Bearer ob_live_YOUR_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "google/gemini-3.1-pro-preview-customtools",
"messages": [{ "role": "user", "content": "Hello" }]
}'
It transcribes too — it takes audio, so the same key reaches it at
https://brain.deployd.network/ai/v1/audio/transcriptions. No per-minute rate: a recording is billed as the tokens it
becomes, at the input price above.
curl https://brain.deployd.network/ai/v1/audio/transcriptions \
-H "Authorization: Bearer ob_live_YOUR_KEY" \
-F file=@audio.mp3 \
-F model=google/gemini-3.1-pro-preview-customtools
