| name: Build ctranslate2-server binaries | |
| # Builds the bundled `ctranslate2-server` variants — CUDA (NVIDIA) and CPU | |
| # fallback — then uploads them as GitHub artifacts so `build.yml` can attach | |
| # them to installer builds. | |
| # | |
| # Triggered: | |
| # * manually via workflow_dispatch (release-blocking binary refresh) | |
| # * automatically when the build script or its companion files change | |
| # | |
| # ponytail: single-host CPU builds are cheap; the CUDA variant requires a | |
| # self-hosted runner with the matching SDK. Linux matrix entries probe for | |
| # nvcc + exit 0 with a hint when the toolchain is missing rather than | |
| # failing CI outright — useful smoke-test signal. | |
| # | |
| # Replaces `build-whisper-binaries.yml`. See | |
| # docs/engineering/stt-ctranslate2-migration.md for the full decision. | |
