# syntax=docker/dockerfile:1.6
# PUBLIC base image for the cheap CPU ESTIMATE job (HF Jobs) — slim, no GPU stack.
#
# Same contract as deploy/hf-image-llama-cpp/Dockerfile: ONLY open-source, generic dependencies — NO
# proprietary code, and no names that reveal which models/techniques the pipeline uses. The Job's
# bootstrap (/opt/run-job.sh) pulls the private wheel + job modules at startup and runs run_job.py.
#
# This variant is CPU-ONLY and slim: it omits CUDA/torch and the GPU inference servers (the estimate
# runs zero signals and starts no model server — run_job.py returns at the ESTIMATE_ONLY branch
# before anything loads), and it omits an optional dependency group that `import dataset_reviewer`
# no longer pulls eagerly. Both shrink the image and its pull time, which is the bulk of the
# estimate's wall-clock. A lightweight tokenizer loads via the Rust `tokenizers` backend, so no
# torch is needed.
#
# Build: HF_JOB_IMAGE_DIR=hf-image-estimate HF_JOB_IMAGE_BASE_PROVIDES=torch \
#        HF_JOB_IMAGE_SPACE=<owner>/cpu-estimate-base make deploy-hf-job
# (run-job.sh + the dataset_reviewer stub are shared from deploy/hf-image-common/; the omitted dep
#  group is applied automatically for this variant — see deploy/deploy_hf_job.py.)
