## Civitai — model version files (the 'arbitrary 65 GiB blob' hub)

- `storage/civitai-model-version-files` | qualifies-with-caveat | evidence reported | binding per-object-cap | category media
- identity a placeholder: card and phone unknown | verified 2026-10-21 (inherited) | stale on 2026-11-05
- url https://civitai.com
- free tier: No published per-account or per-file byte quota. Its own Data Storage Policy states: 'By default, uploaded content will be stored indefinitely with the exception of input and output files related to model training.' Empirically: a single file of 65.83 GiB exists in production, and single free accounts hold 453 GiB (Lykon, 212 models) and 97 GiB (NanashiAnon, 412 models). | unit: GiB | metered on: stored-bytes | read on: 2026-10-21 | source: [1]
- per-object cap: single file of 65.83 GiB | bytes: 70684424273 | source: [1] | note: not stated
- retention: No published per-account or per-file byte quota. Its own Data Storage Policy states: 'By default, uploaded content will be stored indefinitely with the exception of input and output files related to model training.'

- egress: Unmetered; downloads 307-redirect to civitai-delivery-worker-prod...r2.cloudflarestorage.com with a 24 h X-Amz-Expires, then serve 206 with Accept-Ranges: bytes. No per-GB egress charge exists on any Civitai page. | metered: no
- identity: institution
- interface: rest, rclone, cli
- limits:
  - per-object-cap (binding): single file of 65.83 GiB [1]
- limits note: per-object-cap: >=65.83 GiB observed, no published number. THE BINDING CONSTRAINT IS NOT SIZE — it is a per-object access flag plus NSFW gating: creators may set 'require login to download', and such files return HTTP 401 with body {"error":"Unauthorized","message":"The creator of this asset requires you to be logged in to download it"} on BOTH ranged and full GETs (verified consistent — no ranged-lies-while-full-gates behaviour, unlike some round-1 hosts). Of 20 large models sampled, 12 were anonymous-206 and 8 were 401. Training-data retention is a separate, much shorter clause: inputs and training outputs are 30 days. Published per-account storage: Vault is paid-only (Bronze 100 GB / Silver 250 GB / Gold 500 GB) and is a separate product from model hosting.
- interface detail: rest
- tooling: Public REST API v1 (no auth for reads/metadata): /api/v1/models, /api/v1/model-versions/{id}, /api/v1/model-versions/by-hash/{sha256}. Download via GET /api/download/models/{versionId}. Working clients: civitai/cli (official, `civitai download` needs a token), RtypeStudios/CivitAI-Model-Archiver. No rclone backend.
- composes with: Free accounts carry no stated limit and each holds the same allowance. Models per account and versions per model are unlimited, with a per-file ceiling >=65.8 GiB. 30 TiB = ~460 files at the observed 65.8 GiB ceiling, i.e. one account pushing ~460 'models'. Verified excess-use precedent already on the platform: model 1219185 is literally titled 'hunyuanvideo-lora-training-wsl-ubuntu-system-backup' and is a 65.83 GiB zip of a WSL Ubuntu install uploaded as type 'Other'.
- reliability: Downloads are reliable and hash-exact when ungated: a full 13,649,928-byte fetch matched the API-advertised SHA-256 exactly (8184D4BA...). Rate: sustained 20 ranged GETs with no 429. The trap is silent partial bodies — a curl without -f writes the 106-byte JSON 401 body to disk as if it were your file, so every download must be hash-checked.
- notes: the same as the free tier
