What is profileCI?
Profile-likelihood confidence intervals for any fitted model, in a feed that publishes out of order.
profileCI computes confidence intervals from the profile log-likelihood for user-supplied fitted models, generalising what confint.glm does for GLMs to any model object exposing a log-likelihood. The releases handle the awkward cases that make profiling fail in practice: infinite limits when the profile never drops below the interval threshold, bounded profiling ranges, and interpolation that breaks down near the limits. Only convex log-likelihoods are supported, so disjoint intervals are out of scope by design.
What is WorkOS?
WorkOS is building the identity layer for agents while quietly making it easy to switch to it.
WorkOS sells enterprise-readiness infrastructure — SSO, SCIM directory sync, and AuthKit — to application developers. The recent work runs on two tracks. One is a fast-moving agent stack: agent identities registering through an open protocol, a proxy that calls third-party APIs so applications never hold user tokens, and Atlas, an AI coworker that is an end-user product rather than a developer primitive. The other is adoption and developer experience, including a local API for CI/CD testing and a reversible SCIM migration bridge.

profileCI
0.0INFRA · APIS
Profile-likelihood confidence intervals for any fitted model, in a feed that publishes out of order.
◆ Current state
profileCI computes confidence intervals from the profile log-likelihood for user-supplied fitted models, generalising what confint.glm does for GLMs to any model object exposing a log-likelihood. The releases handle the awkward cases that make profiling fail in practice: infinite limits when the profile never drops below the interval threshold, bounded profiling ranges, and interpolation that breaks down near the limits. Only convex log-likelihoods are supported, so disjoint intervals are out of scope by design.
◆ Where it's heading
Work is concentrated on numerical reliability rather than scope: 1.1.1 replaced quadratic with monotonic cubic spline interpolation because the quadratic form could fail, and corrected parameter values stored near the confidence limits. The feed publishes these out of order, with the v1.0.0 entry stamped six months after v1.1.0 and carrying the package's full description rather than a changelog, so release order should be read from the version numbers rather than the dates. The same maintainer's revdbayes has been in pure maintenance across this period, which places profileCI as the more active project.
◆ Prediction
Expect further robustness work at the profiling limits and more logLikFn methods for common model classes, following the nls method added in 1.1.0.
WorkOS
8.8INFRA · APIS
WorkOS is building the identity layer for agents while quietly making it easy to switch to it.
◆ Current state
WorkOS sells enterprise-readiness infrastructure — SSO, SCIM directory sync, and AuthKit — to application developers. The recent work runs on two tracks. One is a fast-moving agent stack: agent identities registering through an open protocol, a proxy that calls third-party APIs so applications never hold user tokens, and Atlas, an AI coworker that is an end-user product rather than a developer primitive. The other is adoption and developer experience, including a local API for CI/CD testing and a reversible SCIM migration bridge.
◆ Where it's heading
The agent releases fit together as one bet: if agents are going to act on users' accounts, someone has to issue their identities and hold their credentials, and WorkOS is positioning to be that party in both cases. What is notable is the pairing with go-to-market plumbing. A reversible SCIM proxy with zero downtime and safe rollbacks is not a capability story, it is a switching-cost story, and shipping it alongside the agent work suggests confidence that the platform is worth migrating onto.
◆ Prediction
Expect the agent identity and token custody pieces to converge into a single documented stack, since Pipes and Agent Registration currently solve adjacent halves of the same problem. Atlas remains the thinnest-described release and the least clear in intent.
