That works for me, though. So it’s not the prompt. It could be a quota problem, or maybe you’re in a region not yet supported by the AI. The AI isn’t available everywhere on this planet.
If you use TOR or a proxy then that might be the problem, although I think it’s more a quota problem.
The “content blocked” message on safe prompts is almost always caused by the Safety Settings in AI Studio being set to their most restrictive level.
Look for the Safety Settings panel on the right side of your screen and adjust the sliders from “Block most” to a more moderate setting like “Block some”.
After you adjust the settings, start a New Chat to reset the context, and your prompts should work as expected.
Try clearing your browser’s cache and cookies to rule out any technical glitches.
After adjusting the safety filters, start a new chat for the changes to apply. In the new chat, type a simple, safe prompt like, “Tell me a story about a friendly robot.” Ensure you don’t copy paste the prompt, to ensure no hidden characters are causing the issue.
