| Disadvantages | โThe 'Le Chat' name is retired, which can cause confusion for users looking for the old brand โMistral Medium 3.5 is only in public preview, so expect occasional instability โThe consumer subscription is billed separately from the developer API, so plans include no API credits โTeam billing carries a $50/mo minimum, making it less attractive for very small teams โCloud coding agents and persistent-memory agent workflows add complexity beyond a simple chat assistant | โFree tier now shows ads to US logged-in adults and has capped usage โCan still generate confident but incorrect answers โThe best features (1M context, Sora, high quotas) require the $100-$200 Pro tiers โGPT-5.6 (Sol/Terra/Luna) is limited preview only, not production-ready โCosts add up quickly for teams once you move beyond Plus |
