AI subscriptions at USD 20 or less
Two related plans fall outside the table. Google AI Plus lists Gemini 3.6 Flash, not Gemini 4 Argon, and Google’s plans page did not show its US price when we checked. T3 Chat does not keep a stable public pricing page, so its comparison with Capriole AI explains how its usage buckets work instead of quoting a price. Multi-model AI chat platforms compares Capriole AI with Magai, T3 Chat, Venice, and OpenRouter beyond price.
Which plan fits which person
- You want the best model from every vendor for one price. Capriole AI Premium is the plan in this list that covers GPT-6 Astra, Claude Fable 5.1, Claude Opus 5.5, and Gemini 4 Argon in one subscription, for less than half the price of the USD 20 plans. Switch models mid-chat to get a second answer from another vendor in the same thread.
- You also build apps or use coding agents. Capriole AI Premium’s API allowance works with the OpenAI and Anthropic API formats and 10 documented coding agents; the API column shows what the other plans include.
- You only need everyday chat. ChatGPT’s free plan may be enough. Capriole AI Premium costs the same USD 8 as ChatGPT Go and adds the four flagships.
What USD 8 gets you on Capriole AI
Premium is unlimited web chat on every supported model, including GPT-6 Astra, Claude Fable 5.1, Claude Opus 5.5, and Gemini 4 Argon. Signed-in web chat has a fair-use limit of 200 messages per account per day. It stops scripted, automated abuse; normal use stays well below it. The same plan includes an API that costs up to 92% less than official API prices: 5M API tokens a month, then USD 8 per 5M tokens of any supported model. Files and web search, projects, chat export, and storage controls are part of the workspace, and free image generation with GPT Image 2.5 and Nano Banana 2.1 is also included. Plans and limits lists everything in Free, Premium, and Team.What you give up
Capriole AI is an independent workspace, not affiliated with OpenAI, Anthropic, or Google, so features that exist only in their apps stay there, such as memory, connectors to other apps, their desktop and mobile apps, and Google AI Pro’s 5 TB of storage and Gemini in Gmail, Docs, and Sheets. Capriole AI also has no voice conversation mode and no video or music generation. Coding agents use the metered API balance, not unlimited chat, so heavy agent work costs USD 8 per 5M tokens beyond the included allowance.Frequently asked questions
