| Fact | Charisma.ai | OpenAI ChatGPT and GPT API |
|---|---|---|
| Pricing | Charisma.aiverified Pro is pay as you go at $5 per 50,000 credits, which the page estimates at about 200 experience minutes. | OpenAI ChatGPT and GPT APIverified The API pricing page lists gpt-image-2.5-sunburst at $8.00 input, $30.00 output, and $2.00 cached input for image tokens, per 1M tokens.

| Commercial use | Charisma.aiverified The terms say stories can be used for any purpose, including commercial purposes, as long as you follow Charisma's terms. | OpenAI ChatGPT and GPT APIverified OpenAI's Terms of Use for individuals cover ChatGPT and its image tools. They say you own the Output and OpenAI assigns you its rights in it, to the extent the law allows. The terms do not split this by free or paid plan. |
| Ownership of outputs | Charisma.aiverified The customer who owns a story is deemed the owner of the output generated into it, including its intellectual property rights. | OpenAI ChatGPT and GPT APIverified The Services Agreement covers the API, ChatGPT Business, and ChatGPT Enterprise. The customer owns all Output, and OpenAI assigns its rights in it. |
| License caveat | Charisma.aiverified Text-to-speech audio made on the platform is not owned by the customer; it is used under a sub-licence from Charisma. | OpenAI ChatGPT and GPT APIverified Output may not be unique, and other users can get similar output. Your ownership does not extend to someone else's similar output. |
| Steam disclosure | Charisma.aiverified If characters generate dialogue while the game is running, Steam classifies that as Live-Generated and asks what guardrails stop illegal output. Pre-Generated rules still apply. | OpenAI ChatGPT and GPT APIverified Player-facing art, sound, narrative, or localization made with this tool is the kind of shipped content Steam's Content Survey asks about (Pre-Generated). This is Valve's rule, not a statement from the vendor. |
| Engines and export | Charisma.aiverified The terms say a Pro Licence can publish or integrate Pro Stories into an external platform such as a Unity or Unreal Engine game, a website, or a mobile app. | OpenAI ChatGPT and GPT APIverified The Image API returns base64 image data, PNG by default, with JPEG or WebP on request. Engine import is up to you. |
