Agents are getting good at acting. They're still bad at remembering. Spectron, the memory and knowledge layer for AI agents built on SurrealDB, addresses this. Early access opens today. Learn more. 👉 sdb.li/4fXn8g4

Graph queries in Postgres 19 are the start of a journey, not a destination. Postgres takes a pragmatic, incremental approach to adding functionality. For instance, way back in 2012, Postgres added its first JSON support. @craigkerstiens declared "we cheated" because it was just a text field with JSON validation layered on top of it. Two years later, JSONB was launched. New releases continue to add additional indexing capabilities and operators. Now, both JSON and JSONB have their place. We expect Postgres 19's SQL/PGQ implementation to be similar. The initial release probably won't replace much workflow. It is limited to fixed-depth queries, which is already quite easy with current SQL implementations. But, you have to start somewhere! What is implemented? DDL definition: a graph is declared and named. `CREATE PROPERTY GRAPH org_graph` declares which tables are vertices and edges, once. Queries can reference the graph by name. Schema changes propagate automatically, clear errors if a query references a vertex/edge that no longer exists, and no dropping tables with associated graphs. Ever written a large CTE query that no fails due to a schema change? Yeah, me, either. Query syntax: query syntax that follows SQL:2023 standards. For instance, `(a)<-[IS reports_to]-(b)` means b reports to a. You get the standard composability of SQL because GRAPH_TABLE behaves as a table. So, join it, filter it, aggregate it, put it in a CTE, and think of GRAPH_TABLE as a new FROM clause source. The question answered with this implementation is: "What is the least we can build that gets us started?" The answer appears to be DDL support and supported query syntax. What SQL/PGQ can't do yet that recursive CTEs still do better: Variable depth: if you need all descendants at any depth, SQL/PGQ in Postgres 19 is fixed-depth only. You must spell out each hop explicitly, which means you need to know the max depth at the time you write the query, which means the query can get lengthy. Aggregation along the path: CTEs can build up arrays, concatenate paths, compute running totals as they recurse. The future: As with JSON support, just wait, and you'll look up after a few releases and say "oh, now it can do that too."

I'm a bit surprised about this clause disallowing benchmarking of Planetscale planetscale.com/legal/aup - access any portion of the Services for the purpose of building a similar or competitive product or service, or monitor the Services for any benchmarking or competitive purpose; @PlanetScale @samlambert Am I missing something here? Benchmarking seems to be encouraged here: planetscale.com/benchmarks but disallowed in the AUP

$5 per mil in, $30 per mil out. GPT-5.5 is smart. I've been using it for a bit. It's also weird, hard to wrangle, and too expensive IMO. Double the price of GPT-5.4. 20% more expensive than Opus 4.7.

Introducing GPT-5.5 A new class of intelligence for real work and powering agents, built to understand complex goals, use tools, check its work, and carry more tasks through to completion. It marks a new way of getting computer work done. Now available in ChatGPT and Codex.
