Capacities vs Jellyfin: at a glance
What is Capacities?
AI stopped being a bundled feature at Capacities and became the thing you buy more of
Capacities ships a numbered release every few weeks across its knowledge-base app — objects, tabs, the editor, presentation mode — with AI threaded through most of them. Recent releases added a choice of AI model provider, chat connectors, image analysis for Pro users, and in July a full public API. The newest release introduces Pro+ and Believer+, optional paid add-ons that raise the monthly AI budget and sell top-ups on top of it.
What is Jellyfin?
Seven candidates in, 12.0 is still trading features for correctness in the metadata layer.
RC7 continues the pattern the 12.0 train set: twelve changes, nearly all in the library and metadata layer, and none adding surface. The substantive ones tighten access control — search candidates are now filtered by user access in a single query, and permissions are enforced on similar-items lookups — alongside episode and season counting fixes for virtual items, anime provider IDs on season folders, and progress logging for data migrations. The release still restates the versioning change introduced at RC1, where the leading 10. was dropped so 10.11.x becomes 12.x, and still requires 10.10.7 or 10.11.x as an upgrade floor.

◆ Current state
Capacities ships a numbered release every few weeks across its knowledge-base app — objects, tabs, the editor, presentation mode — with AI threaded through most of them. Recent releases added a choice of AI model provider, chat connectors, image analysis for Pro users, and in July a full public API. The newest release introduces Pro+ and Believer+, optional paid add-ons that raise the monthly AI budget and sell top-ups on top of it.
◆ Where it's heading
Two arcs are converging. The first opened the product up: API 2.0 made the knowledge base programmable, and connectors let outside assistants reach it. The second is now closing around cost — AI has moved from a bundled capability to a budgeted one, and the new tiers charge for consumption rather than for features. Read together, Capacities is treating the knowledge base as the durable asset and inference as a metered resource priced separately from it.
◆ Prediction
Expect AI budget to become an explicit dimension of the plan comparison, with limits and top-up sizing tuned in follow-up releases. The entries do not show how the budget is measured, so the unit being sold remains unclear.

Seven candidates in, 12.0 is still trading features for correctness in the metadata layer.
◆ Current state
RC7 continues the pattern the 12.0 train set: twelve changes, nearly all in the library and metadata layer, and none adding surface. The substantive ones tighten access control — search candidates are now filtered by user access in a single query, and permissions are enforced on similar-items lookups — alongside episode and season counting fixes for virtual items, anime provider IDs on season folders, and progress logging for data migrations. The release still restates the versioning change introduced at RC1, where the leading 10. was dropped so 10.11.x becomes 12.x, and still requires 10.10.7 or 10.11.x as an upgrade floor.
◆ Where it's heading
The stated goal of 12.0 has been to polish the backend rewrite that shipped in 10.11.0, and seven candidates in, that is still what the changes are. What has shifted subtly across RC5 to RC7 is the kind of correction: earlier rounds were query-cost work such as SQLite caching and batched lookups, while RC7 pairs performance with access enforcement, folding permission checks into the same queries rather than filtering afterwards. That combination usually appears when a rewrite is being audited rather than extended.
◆ Prediction
The change count per candidate is falling and the remaining work is concentrated in one contributor's metadata fixes, which points to 12.0 going final rather than to an RC8 carrying anything new. Nothing in this feed indicates when.
