Models & credit rates

Otter connects one OpenAI-compatible API to several major providers plus open-weight hosts, so you can pick models without juggling separate accounts. Text rows list input and output credits per 1M tokens and typical max context. Image rows list credits per output where applicable. Usage debits your credit balance; see Billing for packs and tiers.

Text models use POST /v1/chat/completions; image models use POST /v1/images/generations (OpenAI / Together-compatible JSON). Usage debits your balance; see Billing for top-ups.
