What is Gumloop?

Gumloop 13.1 lets live artifacts drive agents through the SDK and opens outputs in Office.

Gumloop ships a numbered release every few days. In October it gave agents a real browser (12.0), agent-owned secrets, team sharing and embeddable AI artifacts, then 13.0 rebuilt the agent harness for longer work and added organization-wide evaluations. 13.1 lets scripts in live artifacts message, create and list agents, artifacts, skills and teams through the Gumloop SDK, opens agent-made files in Google Workspace or Microsoft Office, and lets agents on a call run long tasks in the background while they keep talking.

What is Sulu?

Sulu adds AI disclosure fields to media, shipped to both supported lines the same minute

Sulu is a Symfony-based CMS for developer-built sites, released as a synchronised pair: every 3.0.x patch ships within a minute or two of the matching 2.6.x patch, carrying largely the same pull requests. The 3.0.9 / 2.6.26 pair is the most substantive in months. Media assets gain Origin and AI Disclosure information, delivered as a doctrine migration with new columns and an updated form metadata snapshot, and the AI platform integration now reports a reason when it turns a request down. Two-factor setup adds an authenticator app (TOTP) flow and a Google Authenticator method, and a deprecation batch retires AbstractRestController, RestControllerTrait, ApiWrapper and the persistence component repositories and traits.

Gumloop 13.1 lets live artifacts drive agents through the SDK and opens outputs in Office.

◆ Current state

Gumloop ships a numbered release every few days. In October it gave agents a real browser (12.0), agent-owned secrets, team sharing and embeddable AI artifacts, then 13.0 rebuilt the agent harness for longer work and added organization-wide evaluations. 13.1 lets scripts in live artifacts message, create and list agents, artifacts, skills and teams through the Gumloop SDK, opens agent-made files in Google Workspace or Microsoft Office, and lets agents on a call run long tasks in the background while they keep talking.

◆ Where it's heading

The product is moving from building agents to operating them at org scale, and artifacts are turning into small apps that can control agents themselves. Model access is also being made easier to manage, with families, deprecation dates and fallback visibility.

◆ Prediction

Expect more of the SDK exposed to artifacts and further evaluation and Insights controls at the usual weekly pace; the entries don't show pricing changes.

Sulu adds AI disclosure fields to media, shipped to both supported lines the same minute

◆ Current state

Sulu is a Symfony-based CMS for developer-built sites, released as a synchronised pair: every 3.0.x patch ships within a minute or two of the matching 2.6.x patch, carrying largely the same pull requests. The 3.0.9 / 2.6.26 pair is the most substantive in months. Media assets gain Origin and AI Disclosure information, delivered as a doctrine migration with new columns and an updated form metadata snapshot, and the AI platform integration now reports a reason when it turns a request down. Two-factor setup adds an authenticator app (TOTP) flow and a Google Authenticator method, and a deprecation batch retires AbstractRestController, RestControllerTrait, ApiWrapper and the persistence component repositories and traits.

◆ Where it's heading

Three threads run through the pairs and their balance has shifted. Editor and framework upkeep continue — Symfony 8 request bag replacements, PHPStan baselines kept green — but this release adds two things that aren't maintenance. The media provenance work puts AI disclosure into the content model itself rather than leaving it to editors, which is the shape of a CMS preparing for disclosure obligations. The controller and repository deprecations point the other way, at an API layer being cleared out ahead of whatever 3.x becomes, since 3.0 has otherwise read like a maintenance branch alongside 2.6.

◆ Prediction

Expect the deprecated REST controller and persistence layers to be removed in a future major, since deprecating four API surfaces in one release is how Sulu signals a rewrite is staged. Whether the AI disclosure fields are surfaced on the delivery side or stay editorial metadata isn't visible in these entries.
