Claude natively — no model-picker required.
Chatbase Hobby gives you multi-model selection: GPT-4o, Claude, Gemini, DeepSeek, Meta — you choose. saavos ships Claude Sonnet 4.6 on every paid plan, period. If you want a well-calibrated frontier model without a setup decision, that's the trade-off: saavos is an opinionated default; Chatbase is a menu.
