fix: make tiled VAE reuse the compute buffer (#821)

feat: increase work_ctx memory buffer size (#814)

feat: use Euler sampling by default for SD3 and Flux (#753)

Thank you for your contribution.

fix: do not force VAE type to f32 on SDXL (#716)

This seems to be a leftover from the initial SDXL support: it's
not enough to avoid NaN issues, and it's not not needed for the
fixed sdxl-vae-fp16-fix .

fix: harden for large files (#643)

fix: make weight override more robust against ggml changes (#760)
