querychat vs tulpa: at a glance
What is querychat?
Natural-language data querying that outgrew both single tables and Shiny.
querychat puts a natural-language chat interface over a data source, translating questions into SQL and filtering a dashboard from the result. It ships as parallel Python and R packages from one repository, with the Python side consistently ahead and the R side receiving ported features in batches — so the feed interleaves two version series that should not be read as one. Recent releases have expanded both what it can be embedded in and what it can be asked.
What is tulpa?
A Bayesian spatial engine reshaping itself so downstream packages own their own diagnostics.
tulpa is the C++/R inference engine sitting under a family of ecological occupancy packages, tagging releases several times a week in the 0.0.x range. The current window splits cleanly in two: an API move that turns its calibration and goodness-of-fit entry points into S3 generics, and a run of numerical-correctness work in the nested-Laplace grid. A notable share of releases exist to record a measurement that produced no code change at all.

◆ Current state
querychat puts a natural-language chat interface over a data source, translating questions into SQL and filtering a dashboard from the result. It ships as parallel Python and R packages from one repository, with the Python side consistently ahead and the R side receiving ported features in batches — so the feed interleaves two version series that should not be read as one. Recent releases have expanded both what it can be embedded in and what it can be asked.
◆ Where it's heading
Two expansions define this window. The package broke out of Shiny to support Gradio, Dash and Streamlit, and broke out of the single-table model to reason across related tables with joins and cross-table aggregation. Alongside those, the answer format widened from tables to inline charts through ggsql. The remaining work visible here is polish on the chat experience itself — cancellation, suggestion cards, deferred initialisation for per-user credentials — which suggests production deployment rather than demo use is now driving the roadmap.
◆ Prediction
Expect the R package to continue absorbing Python-side features on a lag, with multi-table support the most likely next port given it is the largest capability the two now differ on.

6.3ANALYTICS
A Bayesian spatial engine reshaping itself so downstream packages own their own diagnostics.
◆ Current state
tulpa is the C++/R inference engine sitting under a family of ecological occupancy packages, tagging releases several times a week in the 0.0.x range. The current window splits cleanly in two: an API move that turns its calibration and goodness-of-fit entry points into S3 generics, and a run of numerical-correctness work in the nested-Laplace grid. A notable share of releases exist to record a measurement that produced no code change at all.
◆ Where it's heading
The generics conversion and the new cross-Hessian return value point the same way: the engine is being reshaped into something downstream packages extend rather than wrap, with the extension points made explicit. The correctness fixes cluster tightly on the joint nested-Laplace driver — indefinite Hessians hitting negative pivots, chunk counts read from live machine load, grid cells silently dropped from a fit — which is where the remaining risk visibly sits. Reported numbers have moved more than once in this window, so the project is still finding cases where earlier answers were wrong rather than merely imprecise.
◆ Prediction
Expect the rest of the diagnostics layer to finish migrating onto generics, and continued hardening of the batched joint driver's dense path, which is the one route that recently diverged from its own single-species equivalent.
