AI Fiesta

AI Fiesta is a multi-model AI workspace for people who want to ask one question and weigh several premium-model responses without switching among separate services. In a single chat, users can turn individual models on or off, review their answers side by side, and continue the conversation while retaining its context. Its Super Fiesta mode is designed to choose a suitable model automatically for a query, while still allowing users to request alternatives in the same thread. Custom Projects add reusable system instructions, so a team or individual can establish rules for a task such as marketing work or code review and keep outputs aligned across chats. The platform also includes prompt enhancement, memory, image generation, audio transcription, and editable outputs. Beyond general chat, AI Fiesta offers optional avatar-based conversations, short cognitive games with progress tracking, and a Promptbook for paid users. Its stated model lineup includes ChatGPT, Gemini, Claude, Perplexity, DeepSeek, Grok, Kimi, Qwen, and Mistral. The service is aimed at users who value comparing different AI approaches, maintaining a shared working context, and consolidating access to multiple models under one subscription. It can be used in a mobile browser, with Android and iOS apps also available.
