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 Clair?

Clair 4.10 RC can read SBOMs to match Java vulnerabilities.

Clair cut its first 4.10.0 release candidate on November 13, eleven months after 4.9.0. Its Java indexers can now read CycloneDX SBOM files and treat them as the source of truth, and Red Hat's VEX data now covers Maven advisories, so Java packages in Red Hat images can be matched. It also reduces memory use when many packages share a source package.

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.

Clair 4.10 RC can read SBOMs to match Java vulnerabilities.

◆ Current state

Clair cut its first 4.10.0 release candidate on November 13, eleven months after 4.9.0. Its Java indexers can now read CycloneDX SBOM files and treat them as the source of truth, and Red Hat's VEX data now covers Maven advisories, so Java packages in Red Hat images can be matched. It also reduces memory use when many packages share a source package.

◆ Where it's heading

Since 4.8 Clair has moved from Red Hat's older OVAL data to VEX, and each release follows Red Hat's security data more closely. 4.10 adds SBOMs as an input, so Clair can match what an image's own manifest declares, not only what it finds on disk.

◆ Prediction

More 4.10 release candidates and then a final are likely; the long gap between releases suggests that could take weeks.
