API pricing

Tabba app · Last updated: 15 June 2026

Tabba's AI feature works on a Bring Your Own Key model: you connect your own API key from the provider of your choice and pay that provider directly. Doongu receives no payment and takes no commission. This page helps you estimate what that actually costs.

How it works

Each AI analysis sends a short request and receives a structured JSON response. Pricing is based on tokens — the unit AI providers use to measure text (and image) length.

Token usage per analysis

Each request is composed of the following elements:

ElementTokens
System prompt (role + JSON format)~400
Compressed photo (512×512 JPEG)~1,000–1,500
Text description~50
JSON response (3–5 foods + macros)~350
Analysis typeInputOutputTotal / request
Photo~1,950 tokens~350 tokens~2,300 tokens
Text~450 tokens~350 tokens~800 tokens
Weighted average (60% photo / 40% text)~1,700 tokens

The costs below assume 4.5 requests per day (average between 3 and 6), which represents typical daily use of the food diary.

Recommendation

For a personal food diary (daily use, personal key), from cheapest to most capable:

  1. OpenRouter :free — free, rate limited, variable quality
  2. Mistral free tier — free, Europe, Pixtral vision, ~$0/month
  3. Gemini 2.5 Flash / Mistral Pixtral-12B (paid) — <$0.04/month at 4.5 req/day
  4. GPT-4o mini — ~$0.06/month, excellent value
  5. Claude Haiku 3.5 — ~$0.33/month, very clean output
  6. GPT-4o / Claude Sonnet 3.5 — ~$1–1.25/month, premium

Most users will not exceed $0.05/month with an eco paid model.
