Yes, you can chat with **GPT-6 Astra**, **Claude Fable 5.1**, **Claude Opus 5.5**, and **Gemini 4 Argon** without creating an account. Open [Capriole AI](https://www.capriole.ai/), choose a model, and send up to 5 messages a day as a guest. A free account adds 500,000 tokens of web chat a month, and Premium costs **USD 8 a month** for unlimited web chat. Premium also includes an API that costs up to 92% less than official API prices, so the same account can run your apps and coding agents. ## Guest, free account, and Premium compared | | Guest (no account) | Free account | Premium | | - | - | - | - | | Price | Free | Free | USD 8 a month | | Web chat | 5 messages a day | 500,000 tokens a month | Unlimited, with a [fair-use limit](https://docs.capriole.ai/guides/plans-and-limits.md#what-unlimited-means) of 200 messages a day | | Models | Every supported web chat model | Every supported web chat model | Every supported web chat model | | Saved chats | Sign in in the same tab to keep the chat | Yes | Yes | | File uploads | No | Yes, with **Server Storage** | Yes, with **Server Storage** | | Image generation | No | Free with GPT Image 2.5 and Nano Banana 2.1, with **Server Storage** | Same as Free | | Projects | No | Yes, with **Server Storage** | Yes, with **Server Storage** | | API access | No | No | 5M API tokens a month included; top-ups cost USD 8 per 5M tokens | Every supported web chat model means the full model menu, not a trial model. It includes GPT-6 Astra, Claude Fable 5.1, Claude Opus 5.5, Gemini 4 Argon, and models from xAI, Z.ai, and Moonshot AI. ## Start a chat without an account 1. Open [www.capriole.ai](https://www.capriole.ai/). 2. Open the model menu and choose a model. **More models** lists the rest. 3. Type in **Ask anything** and send. 4. To keep the chat, select **Log In** and sign in or sign up in the same tab. The chat then opens as a saved chat in your account, with every message in place. Saving it does not count toward your usage. ## What a free account adds A free account turns the daily guest limit into 500,000 tokens of web chat a month, on every supported model. Token use depends on the model and the conversation: thinking models and long chats use more. Signing in also unlocks file uploads, free image generation with GPT Image 2.5 and Nano Banana 2.1, and [projects](https://docs.capriole.ai/guides/projects.md). All three need **Server Storage**, the default. The [chat storage guide](https://docs.capriole.ai/guides/chat-storage.md) explains the other storage modes. Free accounts do not include API access. ## What Premium adds Premium costs USD 8 a month: * **Unlimited web chat** on every supported model, including GPT-6 Astra, Claude Fable 5.1, Claude Opus 5.5, and Gemini 4 Argon. * **An API up to 92% below official prices.** Premium includes 5M API tokens a month, and top-ups cost USD 8 per 5M tokens of any supported model. One key works with [10 documented coding agents](https://docs.capriole.ai/guides/one-api-key-coding-agents.md), including Codex and Claude Code. [Plans and limits](https://docs.capriole.ai/guides/plans-and-limits.md) compares Guest, Free, Premium, and Team side by side. ## Limits to know * **The guest limit is counted per IP address.** People on the same network share the 5 daily messages. * **Guests cannot upload files, create images, or use projects.** Sign in to use them. * **Guest chats are not saved to an account** until you sign in in the same tab. * **Requests still go through Capriole AI and the selected model's provider,** with or without an account. Read [privacy and data controls](https://docs.capriole.ai/guides/privacy-and-security.md) before you share sensitive material. ## How other AI chat apps handle signed-out use * **ChatGPT.** OpenAI says you can use ChatGPT without an account in supported countries. While logged out, you can have only one conversation at a time, and chats are not saved. OpenAI's model guide says logged-out users do not get GPT-5.6 Sol, and GPT-6 Pro, the Chat option powered by GPT-6 Astra, needs a Pro, Business, or Enterprise plan. * **Gemini.** Google says some features of the Gemini web app work without signing in. Other features, and saving your activity, need a Google Account. * **Claude.** Anthropic's help center says new Claude accounts must verify a phone number from a supported location, and there is no way to skip that step. On Capriole AI, one browser tab without an account reaches GPT, Claude, and Gemini models. ## Frequently asked questions > **Can I use GPT-6 Astra without an account?** > > Yes.
