What is Cosmic?

Cosmic retired AI Studio and gave its agents goals — the CMS is becoming an agent runtime.

Six weeks of releases pull in one direction. AI Studio was retired and Cosmic's AI consolidated into three surfaces: Agents, Workflows, and Code. Agents gained goals described in plain language that they work toward on their own, running steps and checking in, plus write access to reusable rich-text Content Blocks rather than read-only reference. Semantic search embeds bucket objects into a vector index so content is retrievable by meaning. The two newest entries add Claude Opus 5 and Kimi K3 to the model lineup.

What is projoint?

projoint spent a year on CRAN paperwork, then shipped a correctness fix it flagged itself.

projoint is an R package for analysing conjoint survey experiments, covering Qualtrics import, reshaping, and quantity-of-interest estimation with inter-rater reliability correction. Most of its release history is CRAN admission work — citation formats, DESCRIPTION fields, \value{} tags, vignette cleanups — with four tags backfilled within ninety seconds of each other on 15 July in non-monotonic version order, so neither tag order nor timestamps in this feed track the real sequence. The substantive releases are the ones fixing data-preparation bugs that silently corrupt estimates.

5.0

Cosmic retired AI Studio and gave its agents goals — the CMS is becoming an agent runtime.

◆ Current state

Six weeks of releases pull in one direction. AI Studio was retired and Cosmic's AI consolidated into three surfaces: Agents, Workflows, and Code. Agents gained goals described in plain language that they work toward on their own, running steps and checking in, plus write access to reusable rich-text Content Blocks rather than read-only reference. Semantic search embeds bucket objects into a vector index so content is retrievable by meaning. The two newest entries add Claude Opus 5 and Kimi K3 to the model lineup.

◆ Where it's heading

The content API is turning into a runtime agents operate inside: goals instead of prompts, write permissions instead of suggestions, and a vector index so an agent can find what it needs without being handed it. Retiring AI Studio is the clearest signal — Cosmic is choosing fewer, deeper surfaces over a menu of separate AI features, which is a harder position to reverse.

◆ Prediction

Expect agent write scope to extend past Content Blocks to objects and media, and goals to gain triggers or schedules so they run without a person starting them.

2.5

projoint spent a year on CRAN paperwork, then shipped a correctness fix it flagged itself.

◆ Current state

projoint is an R package for analysing conjoint survey experiments, covering Qualtrics import, reshaping, and quantity-of-interest estimation with inter-rater reliability correction. Most of its release history is CRAN admission work — citation formats, DESCRIPTION fields, \value{} tags, vignette cleanups — with four tags backfilled within ninety seconds of each other on 15 July in non-monotonic version order, so neither tag order nor timestamps in this feed track the real sequence. The substantive releases are the ones fixing data-preparation bugs that silently corrupt estimates.

◆ Where it's heading

The maintainer is hardening the path from raw Qualtrics export to estimate, which is where conjoint analysis quietly goes wrong. Three separate releases fix that path: dropped respondent-level weights in organize_data(), repeated-task reshaping in reshape_projoint(), and choice-to-profile mapping in 1.1.3. Each fix now arrives with regression tests and stricter validation rather than just a patch, and 1.1.3 adds an explicit .choice_map so the mapping is auditable instead of inferred.

◆ Prediction

Expect the validation-and-regression-test pattern to keep extending across the import path, with releases continuing to arrive in bursts around CRAN submission rather than on a cadence.
