studio/ci: flat GGUF+mmproj cache for Mac json-images smoke, save partial caches on cancel (#5417)
The json-images job on macos-14 has been hitting timeout-minutes: 30 on
cold cache (runs 25854199999, 25854000503, plus concurrency-cancelled
runs like 25848174628). Two root causes, both addressed here.

1. The HF_HOME cache for gemma-4-E2B-it never lands on macOS.

   `gh api repos/unslothai/unsloth/actions/caches` shows a 3344 MB
   Windows entry for the same key on main but no macOS entry at all.
   The save step was gated on `prime-hf.outcome == 'success'`; when
   prime is killed by the job timeout or by `concurrency:
   cancel-in-progress`, outcome becomes `cancelled` and the save is
   skipped. Cold cache then primes again next run, times out again,
   never saves. Self-perpetuating on busy branches.

   On top of that, the HF_HOME layout (xet chunks + blobs + snapshots)
   inflates ~3.6x off-disk per the job 2 comment, pushing a single
   entry close to the 10 GiB per-cache cap.

2. macos-14 NAT egress is slow for multi-GB downloads. The workflow
   already calls this out and goes parallel + authenticated, but 3.4
   GiB (gemma-4-E2B Q4_K_XL ~2.4 GiB + mmproj-F16 ~986 MiB) still
   doesn't reliably fit in 30 min when starting from cold.

Changes

* Job 3 (json-images) switches from HF_HOME to the flat `--local-dir
  gguf-cache` pattern that Job 2 already uses. Cache key swaps from
  `${runner.os}-hf-${REPO}-${VARIANT}-${MMPROJ}-v1` to
  `${runner.os}-gguf-${REPO}-${FILE}-${MMPROJ}-v1`. mmproj is
  auto-detected as a sibling of the .gguf in the same dir by
  `detect_mmproj_file` in studio/backend/utils/models/model_config.py,
  so no API surface change is needed on the inference/load route.

* Load step posts `model_path` as a local file path and drops
  `gguf_variant`. With a local file the variant is encoded in the
  filename, and passing it would route through
  `_find_local_gguf_by_variant` which expects a directory.

* All three jobs' save guards relaxed from
  `outcome == 'success'` to `outcome != 'skipped' && hashFiles(...) != ''`.
  Cache-hit fast path stays a no-op (restore hit -> download skipped
  -> save skipped). On cancel/timeout/failure the save still runs as
  long as at least one .gguf landed, so the next run resumes via
  hf download's content-hash resume.

* Top-of-file and `workflow_dispatch` comments updated from
  "HF_HOME caches" to "model caches" so they remain accurate now that
  two of three jobs use flat-file caching.

This builds on the cache hardening already landed in #5396 and #5399.

Uninstall

You can uninstall Unsloth Studio by deleting its install folder usually located under $HOME/.unsloth/studio on Mac/Linux/WSL and %USERPROFILE%\.unsloth\studio on Windows. Using the rm -rf commands will delete everything, including your history, cache:

  • MacOS, WSL, Linux: rm -rf ~/.unsloth/studio
  • Windows (PowerShell): Remove-Item -Recurse -Force "$HOME\.unsloth\studio"

For more info, see our docs.

Deleting model files

You can delete old model files either from the bin icon in model search or by removing the relevant cached model folder from the default Hugging Face cache directory. By default, HF uses:

  • MacOS, Linux, WSL: ~/.cache/huggingface/hub/
  • Windows: %USERPROFILE%\.cache\huggingface\hub\
