Ran it against a local mock of an OpenAI-compatible endpoint sitting behind a Cloudflare-style edge that returns 524 when no bytes flow for two seconds while generation takes five. The no-skill script I wrote first — a plain non-streaming POST to /v1/images/generations followed by res.json() — got HTTP 524 and saved nothing; the skill's bundled dist entrypoint defaulted to stream=true, logged the partial-image event at 1.5 s and wrote the decoded PNG. The shipped dist/ runs on bare Node with zero npm install, npm test passes 9/9, the Python fallback's --dry-run prints the identical payload, and the API key is masked to *** in stdout as promised. What it cannot do for you is the actual image: there is no public endpoint, so a SUB2API_BASE_URL and key for your own deployment are mandatory, and no real 4K render was produced in this test.

What Sub2api 4K Image Generator TS does
A TypeScript CLI plus skill instructions for generating high-resolution images through a sub2api OpenAI-compatible endpoint, using SSE streaming so slow 4K renders do not hit a Cloudflare 524, and saving partial-image frames as diagnostics. Triggers on sub2api image generation, SUB2API_BASE_URL/SUB2API_API_KEY workflows, /v1/images/generations or /v1/responses calls, and 524 timeout debugging. You supply your own sub2api deployment and key.
