What is Rivet?

Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.

Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.

What is Weaviate?

Weaviate patched its whole cloud estate in 17 hours after the eMudhra CA compromise.

Weaviate's October has been security-heavy: v1.39.3 fixed a Google-module credential leak and then a nearObject cross-collection vector disclosure. Now it reports rotating certificates across its customer estate and platform within 17 hours of the eMudhra leak. On the product side, 1.40 brings PathSeer adaptive filtered search, and Engram is now a Claude Code plugin for persistent agent memory.

7.5

Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.

◆ Current state

Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.

◆ Where it's heading

Each release removes operational burden: BYOC moved the control plane into the customer's cloud, and 3.0 reduces the self-hosted footprint to one binary plus an S3 bucket. The agent work (Pi, agentOS) sits on top as the main workload Rivet is courting.

◆ Prediction

Expect benchmarks and migration guidance for 2.x users during the preview, followed by a 3.0 GA. The entry gives no performance numbers, so the SSD-speed claim is unverified.

5.0

Weaviate patched its whole cloud estate in 17 hours after the eMudhra CA compromise.

◆ Current state

Weaviate's October has been security-heavy: v1.39.3 fixed a Google-module credential leak and then a nearObject cross-collection vector disclosure. Now it reports rotating certificates across its customer estate and platform within 17 hours of the eMudhra leak. On the product side, 1.40 brings PathSeer adaptive filtered search, and Engram is now a Claude Code plugin for persistent agent memory.

◆ Where it's heading

Two threads run in parallel: index and quantization research (HFresh, 4-bit RQ, PathSeer) that lowers memory cost at scale, and an agent-memory layer built on Engram. The security posts suggest Weaviate is preparing to show its operational record to enterprise buyers.

◆ Prediction

Expect 1.40 to reach GA with PathSeer, along with further Engram integrations for other coding agents.
