zerogravity在本地部署好了，API给另外一个做AI PPT和信息图的开源项目使用，模型名称没错，文本生成和图片识别模型使用gemini-3-flash功能正常，但是gemini-3-pro-image图片生成就出错。

Quick correction (clean summary):

Fixed in zerogravity-src and pushed to main at commit 96b2863.

Changes shipped:

generate_image follow-up is now blocked for non-image models (only allowed for gemini-3-pro-image)
added regression tests for both block and allow paths in MITM proxy
inline image base64 is now emitted consistently in streaming for chat completions, responses, messages, and gemini streamGenerateContent
fixed image-only stream completion so responses terminate cleanly
added integration tests for inline-image streaming and completion markers

Verification run:

proxy regression tests (both)
cargo test --bin zerogravity integration_tests
cargo clippy --all-targets
cargo build

Thanks again for the report.

Closing as fixed by commit 96b2863 in zerogravity-src main. If you still hit this on latest, reopen and I’ll dig in immediately.
