Chat 4O (Chat for Omni) positions itself as an all-in-one AI creation platform that integrates large language model chat, AI image generation, and AI video generation into a single interface. According to the official introduction, its target users include both those who want to use AI to solve complex problems and creators who need to quickly produce visual content.
In terms of use cases, Chat 4O mainly covers three types of tasks: first, conversing with mainstream large language models to handle complex problems such as reasoning, programming, mathematics, and writing; second, using image generation tools to turn text or reference images into pictures, with support for various stylization processes; third, using video generation tools to turn text or images into short videos, including animating images, first-and-last-frame animation, and more.
In terms of main capabilities, the platform integrates a large number of models and tools. On the language model side, the officially listed models include OpenAI o1, GPT-4o, GPT-4.1, GPT-5.1, Claude 3.7 Sonnet, Claude Sonnet 4, Claude Sonnet 4.5, Gemini 2.0 Flash, Gemini 2.5 Pro, Gemini 3 Pro, Gemini 3.1 Pro, Gemini 3 Flash, Grok 4, Grok 4.3, DeepSeek V3.2, and others. On the image generation side, it involves Flux AI, Google Nano Banana, Nano Banana 2, Nano Banana Pro, Seedream 4.5 / 5.0, Qwen Image 2, GPT Image 1.5, GPT Image 2 / 2.5, and others. On the video generation side, it involves Kling, Vidu, Seedance 1.5 / 2.0, Veo 3.1, MiniMax H3, and others. The official listing also includes specific tools such as image-to-video, Ghibli-style generation, AI figurine generation, old photo restoration, AI avatars, AI hairstyle filters, and Christmas/Halloween-themed images. Auxiliary tools include AI math problem solving (providing step-by-step solutions), image description, image-to-prompt, text rewriting, and others.
In terms of how to use it, the official description is that users access these models and tools through a unified interface, enter text prompts or upload images to generate images or videos, and can also chat directly with the chat assistant. The platform provides free tool entry points, such as free Nano Banana, free GPT Image 2, free5-second MiniMax H3 video, and others, while also providing model calls in API form (such as Veo 3.1 API, Seedance 1.5 API, Nano Banana 2 API, Seedream 4.5 API). The official FAQ mentions support for API access, mobile use, and credit-based billing, but the materials do not give specific prices, credit consumption values, free trial details, commercial licensing, or specific privacy and security measures.
In terms of applicable scenarios, the officially listed uses include e-commerce product images and advertising assets, social media videos, product demonstrations, UGC clips, avatars and ID photos, old photo restoration, stylized artistic creation, mathematics and science problem solving, programming assistance, academic research workflows, and others.
In terms of limitations, the materials do not provide the available regions for each model, the specific copyright ownership of generated content, output quality, rate limits, or stability explanations. Regarding the relationship between the platform and the providers of the listed models, the official FAQ includes related questions but does not provide answers in the materials. Therefore, information involving charges, free quotas, commercial licensing, and privacy policies is not currently provided and should be based on the actual explanations on the official page.
