epinowcast vs OpenCTI
A side-by-side editorial comparison of epinowcast and OpenCTI — release velocity, themes, recent moves, and the top alternatives to consider.
epinowcast vs OpenCTI: at a glance
What is epinowcast?
epinowcast added Gaussian processes to its formula interface and made the sampler twice as fast
epinowcast is a Bayesian nowcasting toolkit for right-truncated epidemiological count data, built on Stan with a brms-style formula interface. Over 2025-2026 it moved from experimental to stable, prepared for CRAN, and broadened past nowcasting proper — 0.6.0's max_delay = 1 support allows purely retrospective fitting of fully reported counts. 0.7.0 in July 2026 is the largest modelling release in the window.
What is OpenCTI?
OpenCTI spends a release unblocking queues and hardening upserts
7.260817.0 is a fix release. The most consequential item is malformed STIX messages nacking forever and blocking worker queues indefinitely — a stall in the ingestion path rather than a display bug. Alongside it: upsert clearing an existing createdBy when incoming confidence is higher, draft upserts crashing on existing attack patterns, OTP handling in the stream middleware, and case template relation authorization. Score fields were added to threat actor groups, intrusion sets and malware.

◆ Current state
epinowcast is a Bayesian nowcasting toolkit for right-truncated epidemiological count data, built on Stan with a brms-style formula interface. Over 2025-2026 it moved from experimental to stable, prepared for CRAN, and broadened past nowcasting proper — 0.6.0's max_delay = 1 support allows purely retrospective fitting of fully reported counts. 0.7.0 in July 2026 is the largest modelling release in the window.
◆ Where it's heading
The package is converging on a general formula-driven latent process toolkit rather than a single nowcasting model. rw() and arima() were joined in 0.7.0 by gp(), a Hilbert-space reduced-rank Gaussian process placeable on any module's linear predictor with selectable kernels and an integration order matching arima()'s d. Alongside it, the fixed-effects design and integrated residuals are now centred against the module intercept, which the notes report roughly doubles sampling speed on a weekly random-walk growth model.
◆ Prediction
With CRAN preparation done in 0.6.0 and the model surface substantially widened in 0.7.0, the next release is likely a CRAN submission plus consolidation of the gp() kernels. The release notes repeatedly benchmark against EpiNow2's behaviour, suggesting continued convergence between the two codebases.

OpenCTI spends a release unblocking queues and hardening upserts
◆ Current state
7.260817.0 is a fix release. The most consequential item is malformed STIX messages nacking forever and blocking worker queues indefinitely — a stall in the ingestion path rather than a display bug. Alongside it: upsert clearing an existing createdBy when incoming confidence is higher, draft upserts crashing on existing attack patterns, OTP handling in the stream middleware, and case template relation authorization. Score fields were added to threat actor groups, intrusion sets and malware.
◆ Where it's heading
The platform's feature energy went into the connector catalog and integrations rework in July, and the releases since have been consolidating: mass operations on relation times, shareable saved searches, and now a pass over ingestion robustness. Adding score to more entity types continues the slow enrichment of the data model that runs underneath the feature work.
◆ Prediction
Given score arriving on three entity types in one release, expect it to keep spreading across the data model, and the queue-blocking class of bug to draw more worker-side hardening.
