What is Rmlx?

Rmlx spent its first six months deciding where an array actually lives.

Rmlx exposes Apple's MLX array framework to R, giving R users GPU-backed array operations and automatic differentiation on Apple silicon. It reached r-universe in November 2025 and has moved quickly since: float64 arrays in 0.3.0, a reworked device model in the same release, and dimnames and vector names in 0.4.0 that make mlx objects behave like base R arrays under solve(), %*% and friends.

What is Snorkel AI?

Snorkel has stopped labeling data and started defining what agent competence means.

The output is a research and benchmarking program, not a release feed. Recent work argues that single-episode benchmarks measure the wrong thing: agents should be scored across dependent states, tool calls, simulated users, approval rules, and learning carried between tasks. Concrete artifacts back the argument — Senior SWE-Bench with 100 tasks from real pull requests and half the set held private, GDPval+ for professional reasoning, and collaboration on Agents' Last Exam with Berkeley RDI. Alongside these, Snorkel publishes head-to-head evaluations of frontier model releases and hosts a reading group that surfaces outside research.

Rmlx spent its first six months deciding where an array actually lives.

◆ Current state

Rmlx exposes Apple's MLX array framework to R, giving R users GPU-backed array operations and automatic differentiation on Apple silicon. It reached r-universe in November 2025 and has moved quickly since: float64 arrays in 0.3.0, a reworked device model in the same release, and dimnames and vector names in 0.4.0 that make mlx objects behave like base R arrays under solve(), %*% and friends.

◆ Where it's heading

The work so far is about making MLX arrays feel native to R rather than exposing more of MLX. Dimnames preservation across operations, rbind() and cbind() accepting 1D vectors, base-like subsetting semantics with errors on unknown names — these are all conformance to R's conventions. The device rework points the same way: rather than mirror MLX's per-array device, the package adopted scoped context functions that read like R idiom. Expect the surface to keep widening before it deepens.

◆ Prediction

The obvious next targets are more base R generics preserving dimnames and broader coverage of MLX operations; float64 GPU support is blocked upstream by MLX itself, which the notes state directly.

5.0

Snorkel has stopped labeling data and started defining what agent competence means.

◆ Current state

The output is a research and benchmarking program, not a release feed. Recent work argues that single-episode benchmarks measure the wrong thing: agents should be scored across dependent states, tool calls, simulated users, approval rules, and learning carried between tasks. Concrete artifacts back the argument — Senior SWE-Bench with 100 tasks from real pull requests and half the set held private, GDPval+ for professional reasoning, and collaboration on Agents' Last Exam with Berkeley RDI. Alongside these, Snorkel publishes head-to-head evaluations of frontier model releases and hosts a reading group that surfaces outside research.

◆ Where it's heading

Snorkel is moving from evaluation-as-scoring to evaluation-as-training signal: the milestone framing scores intermediate progress, the continual-learning thread treats improvement across a task sequence as the measured quantity, and the newest reading-group post pushes further upstream still, into how much a reasoning model should be trained before it is tested. Publishing benchmarks with private splits and running public model comparisons builds the position that Snorkel is the neutral scorer, which is what makes the enterprise environments business defensible. The through-line is that measurement, not model capability, is the bottleneck.

◆ Prediction

Expect the milestone and continual-learning threads to converge into a named benchmark or environment suite with the same public-private split as Senior SWE-Bench. The feed carries research, talks, and reading-group recaps rather than platform releases, so it does not indicate what ships in the product.
