rollama vs simlandr: at a glance
What is rollama?
rollama turns a local-LLM wrapper into an instrument for reproducible annotation
rollama is an R client for Ollama, aimed at researchers running local models for text annotation and embedding rather than at application developers. Version 0.3.0 adds response caching, logprobs output, batched questions, and a reimplemented structured-outputs path with its own vignette, while syncing against upstream Ollama API changes. The package now covers the full loop a computational social scientist needs: prompt, constrain the output shape, read the model's confidence, and cache the result.
What is simlandr?
Potential landscape tooling settling onto standard R generics after two rounds of renaming.
simlandr builds potential landscape plots from simulations of dynamic systems, with barrier-height calculations and batch simulation grids. Its three substantive releases are all consolidation: parameters renamed, functions renamed, defaults removed. By 0.3.0 the bespoke accessors had been replaced by ggplot2's autolayer() and base summary(), and the package carried print, summary, and plot methods for its own classes.

rollama turns a local-LLM wrapper into an instrument for reproducible annotation
◆ Current state
rollama is an R client for Ollama, aimed at researchers running local models for text annotation and embedding rather than at application developers. Version 0.3.0 adds response caching, logprobs output, batched questions, and a reimplemented structured-outputs path with its own vignette, while syncing against upstream Ollama API changes. The package now covers the full loop a computational social scientist needs: prompt, constrain the output shape, read the model's confidence, and cache the result.
◆ Where it's heading
Each release has pushed further from chat toward measurement. Early versions added multi-model querying and dedicated embedding models; 0.2.0 brought make_query() for annotation and multi-server dispatch; 0.2.1 added structured output and custom headers. The 0.3.0 combination of logprobs and caching is the clearest statement of intent — those are features you add for people who need confidence scores and reproducible reruns, not for people building chatbots. Keeping pace with the Ollama API is the recurring maintenance cost.
◆ Prediction
Expect the annotation path to keep deepening — likely more tooling around logprob-derived confidence and validation of structured outputs — alongside the routine syncing each Ollama API change forces.

◆ Current state
simlandr builds potential landscape plots from simulations of dynamic systems, with barrier-height calculations and batch simulation grids.

By 0.3.0 the bespoke accessors had been replaced by ggplot2's autolayer() and base summary(), and the package carried print, summary, and plot methods for its own classes.
◆ Where it's heading
Every release trades a package-specific name for a conventional one - var and par became arg and ele, get_geom() became an autolayer() method, get_barrier_height() became a summary() method, hash_big.matrix became hash_big_matrix. The one methodological change, an adjusted minimal energy path algorithm, arrived inside a release otherwise full of renames. Removing default values for barrier calculation because they were often unsuitable reads as the maintainer deciding the defaults were doing harm.
◆ Prediction
The feed stops at 0.3.0 in late 2022, mid-consolidation; these entries give no indication of what followed, if anything did.
