flashlight vs rollama: at a glance
What is flashlight?
flashlight hit 1.0 by giving away its SHAP feature and making most of its API internal.
flashlight computes model-agnostic interpretability output — variable importance, partial dependence and effect profiles, breakdown plots — for fitted models in R. Version 1.0.0 in October 2025 executed a contraction announced two years earlier: add_shap() is deprecated in favour of the separate kernelshap and fastshap packages, type = "shap" is gone from every light_* function that accepted it, and eight previously exported helpers became internal. The release also restored compatibility with ggplot2 v4.
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.

◆ Current state
flashlight computes model-agnostic interpretability output — variable importance, partial dependence and effect profiles, breakdown plots — for fitted models in R. Version 1.0.0 in October 2025 executed a contraction announced two years earlier: add_shap() is deprecated in favour of the separate kernelshap and fastshap packages, type = "shap" is gone from every light_* function that accepted it, and eight previously exported helpers became internal. The release also restored compatibility with ggplot2 v4.
◆ Where it's heading
The package is narrowing rather than growing, and doing it on a published schedule — 0.9.0 listed the breaking changes, 1.0.0 applied them essentially unchanged. Handing SHAP computation to dedicated packages leaves flashlight as an effects-and-profiles visualization layer rather than an all-purpose interpretability toolkit. Removing the ability to rename result columns via options() points the same way: fewer configuration surfaces, a smaller contract to maintain.
◆ Prediction
With the deprecation list from 0.9.0 now fully applied, the next releases most likely remove the functions currently deprecated rather than adding capability, and continue tracking ggplot2. The entries show no new analysis method in progress.

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.
