eratosthenes vs Okta
A side-by-side editorial comparison of eratosthenes and Okta — release velocity, themes, recent moves, and the top alternatives to consider.
eratosthenes vs Okta: at a glance
What is eratosthenes?
eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.
eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().
What is Okta?
Okta's developer channel has become an extended argument for Cross App Access as the way agents get authorized.
This feed is Okta's developer blog, so entries are guides and tutorials rather than release notes. Four of the last six are about Cross App Access, the Identity Assertion Authorization Grant implementation Okta is pushing as the mechanism for agent-to-app authorization.

◆ Current state
eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().
◆ Where it's heading
The package is moving from research code to something a non-author can run. Consolidating estimation behind one function, then wrapping every input class in a validator, are the two steps that make failures legible instead of cryptic, and the diagnostics added earlier serve the same end for the sampler itself. Nothing in the window changes the underlying model; the work is all about making it usable and its output checkable.
◆ Prediction
With inputs validated and diagnostics in place, the next release is more likely to extend the constraint or assemblage modelling than to keep reworking the interface, though the feed's three sparse tags give little to read a cadence from.
Okta
5.0INFRA · APISDEVOPS
Okta's developer channel has become an extended argument for Cross App Access as the way agents get authorized.
◆ Current state
This feed is Okta's developer blog, so entries are guides and tutorials rather than release notes. Four of the last six are about Cross App Access, the Identity Assertion Authorization Grant implementation Okta is pushing as the mechanism for agent-to-app authorization.
◆ Where it's heading
The XAA content has moved from explaining the concept to closing adoption gaps: SAML apps that will not migrate to OIDC, a C# MCP walkthrough, and instructions for listing XAA connections on the Okta Integration Network. That progression is what a vendor publishes when it wants a spec adopted rather than admired.
◆ Prediction
Expect further XAA enablement content aimed at specific stacks and more emphasis on OIN listings, since the value of the approach rises with the number of apps on both sides that support it.
