Choosing a Model
BYOK users can choose which AI model to use per project:
- Haiku 4.5 — Fast and affordable. Good for high-volume content.
- Sonnet 4.6 — Balanced quality and cost. Recommended for most use cases.
- Opus 4.6 — Premium quality. Best for high-stakes content where quality is paramount.
Cost Estimates
A typical 2,500-word article with images costs approximately:
- Sonnet (writing) + research + images: ~$0.50–0.80 per article
- Opus (writing) + research + images: ~$1.25–1.50 per article
These are rough estimates and vary based on article length, number of images, and research depth. Research uses OpenAI (gpt-5-mini), images use gpt-image-1.5, and all other stages use Anthropic Claude.
