Chroma is an open-source embedding/vector database used to store and query vectors for AI search and retrieval applications.
ZDI's Pwn2Own Ireland 2026 schedule sets 21 exploit attempts in Cork on October 6, the largest a $300,000 remote Pixel 10 entry. The schedule names exact models and time slots, so operators of the targeted products know which results to look for on ZDI's live leaderboard.

LiveReview's Maneshwar says Gemini File Search cost over 50 cents a review run because a reasoning model performed each search. A local index and a cheaper model brought runs down to 4 cents.

A dev.to post argues that moving embeddings out of Postgres buys a second source of truth, a four-leg query path and 50 to 150 ms of internet latency. Its 8 ms pgvector counter-figure has no benchmark behind it.

A dev.to account of a four-hour agent run shows compaction preserving an abandoned fix in full and losing the operator's correction. The long-context benchmarks in the same post say a bigger window would not have saved it.

A comparison of Mem0, Zep and LangChain's memory classes puts the split at adjudication rather than storage. Mem0 pays two model calls per message to get it.

A consultant's two client failures, a supplier filter and a 10kg shipping quote, both broke on a numeric comparison that top-k similarity does not perform.

A dev.to post argues the layers arrived before the problems. Its strongest evidence, grep beating an embedding pipeline, comes with no name and no numbers, which is the part worth testing yourself.

A dev.to writeup drops vector stores for a SQLite table with tag and timestamp columns. Its own numbers put the practical ceiling at a million rows, not a hundred million.
