What is Sanity?

Sanity is paying down its runtime weight while wiring agents into the content layer.

Two lines of work run in parallel across this window. The platform layer is shedding weight and legacy: @sanity/ui v4.0.0 goes ESM-only, moves heavy components behind subpath imports, and requires a stylesheet import, while the Media Library asset grid switches to viewport-only rendering. The agent layer is filling out fast — two MCP server releases in under a week add CLI execution, explicit release IDs, and transactional document patching, and the React App SDK gains bidirectional presence that interoperates with Studio.

What is Weaviate?

Weaviate is turning the vector database into an agent runtime with tunable search effort

The feed mixes real release notes with developer guides, and the release notes carry the weight. Recent work centers on the Query Agent rather than the storage engine: Search Mode now takes an effort tier, and query profiling exposes per-stage, per-shard timing. The 1.38 release moved the disk-based vector index and a built-in MCP server to general availability, alongside a rebuilt async replication scheduler.

Sanity is paying down its runtime weight while wiring agents into the content layer.

◆ Current state

Two lines of work run in parallel across this window. The platform layer is shedding weight and legacy: @sanity/ui v4.0.0 goes ESM-only, moves heavy components behind subpath imports, and requires a stylesheet import, while the Media Library asset grid switches to viewport-only rendering. The agent layer is filling out fast — two MCP server releases in under a week add CLI execution, explicit release IDs, and transactional document patching, and the React App SDK gains bidirectional presence that interoperates with Studio.

◆ Where it's heading

The MCP server is being hardened into a supervised write path rather than a read-only convenience: patches roll back as a unit, malformed IDs are rejected up front, and schema deploys now refuse to touch a Studio-managed workspace even when stale state says otherwise. That last rule is the direction in miniature — agents are being given real write access, fenced off by workspace ownership. Meanwhile the frontend packages are absorbing a breaking release to make bundle size a property of what you import rather than what ships.

◆ Prediction

The v4.0.0 notes state that more components move off runtime CSS-in-JS across the 4.x minors, so the bundle work continues incrementally rather than in another breaking jump. On the SDK side the presence release explicitly defers rendered remote selections to a forthcoming Portable Text plugin — the most concretely signposted next item in the feed.

Weaviate is turning the vector database into an agent runtime with tunable search effort

◆ Current state

The feed mixes real release notes with developer guides, and the release notes carry the weight. Recent work centers on the Query Agent rather than the storage engine: Search Mode now takes an effort tier, and query profiling exposes per-stage, per-shard timing. The 1.38 release moved the disk-based vector index and a built-in MCP server to general availability, alongside a rebuilt async replication scheduler.

◆ Where it's heading

The center of gravity has shifted from storing vectors to running retrieval as an agentic service. Engram going generally available gave agents managed memory; the MCP server gave them a standard way in; effort tiers now let callers trade latency and cost for search quality on a per-query basis. Operability is being built out in parallel — profiling and replication work are what a database needs once agents, not humans, are issuing the queries.

◆ Prediction

Expect the effort tiers to spread beyond Search Mode into the rest of the Query Agent surface, and the two 1.38 previews — the Boost API and nested object filtering — to reach general availability in a following release.
