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 WorkOS?
WorkOS ships Agent Auth, claiming AI-agent identity before the category has a standard
WorkOS is a developer-focused auth platform shipping at high cadence — 10 entries in 21 days. The platform is hardening its core SSO/OIDC stack (PKCE, Private Key JWT, SCIM migration), adding enterprise depth (10-year audit logs, user groups, email provider flexibility), and just opened a new surface with Agent Auth: per-agent identities that are scoped and revocable. The combination of enterprise compliance features and developer DX work points to a platform that wants to own the full auth stack as B2B SaaS complexity grows.

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.

WorkOS ships Agent Auth, claiming AI-agent identity before the category has a standard
◆ Current state
WorkOS is a developer-focused auth platform shipping at high cadence — 10 entries in 21 days. The platform is hardening its core SSO/OIDC stack (PKCE, Private Key JWT, SCIM migration), adding enterprise depth (10-year audit logs, user groups, email provider flexibility), and just opened a new surface with Agent Auth: per-agent identities that are scoped and revocable. The combination of enterprise compliance features and developer DX work points to a platform that wants to own the full auth stack as B2B SaaS complexity grows.
◆ Where it's heading
Agent Auth is the directional signal — WorkOS is betting that AI agents need the same auth primitives human users do (identity, scope, revocability) and is building that infrastructure ahead of the market. The rest of the window fills in known vectors: broader SSO options, Android SDK, more email providers. The trajectory is more surfaces, more enterprise depth, and an early lead on agentic auth before competitors formalize their approach.
◆ Prediction
Expect deeper agentic auth primitives next — capability-scoped tokens, agent-specific audit trails, and lifecycle management APIs — as customers deploy agents in production and need per-agent visibility rather than just per-user logs.
