Correction

The original description of this PR claimed that merging #12 would leave iOS recommending zero chat models. That is wrong, and I have retracted it below.

I compared ModelRecommendation.swift as it stands on main against the catalog that #12 ships, and treated the two as independent. They are not: #12 updates the recommendation ids in the same change as the catalog. Every id #12 ships resolves in the catalog #12 ships. There is no regression, and nothing here is urgent.

What is actually true, verified against the catalog branch:

  • On hardware where MLX registers (device, Mac), fix(catalog): repoint two model rows at URLs that resolve #12's lists resolve fully. Five candidates on midRange, as intended.
  • On the arm64 simulator, MLX.register() returns false and those rows are absent, so midRange resolves 2 of 5 and lowEnd resolves 2 of 4. Thin, not empty.

So this PR is a robustness change, not a fix. Judge it on that.

What this PR is for

The org taxonomy. This part is unchanged and stands on its own. Eight models in the rebuilt catalog match no publisher rule and land in the generic "Open source" bucket: five Granite (there is no IBM org), maple-preview (the model San named specifically), muse-glimmer (Meta's rule matched llama only), and fara1.5. Adds IBM and Deepgrove orgs and the four missing rules. All 84 catalog ids now resolve to a real publisher. The identical change is in runanywhere-android PR #16.

A floor under the recommendation engine. pickModels and pickFirst matched curated ids exactly and returned nothing else, so the size of the recommendation list is entirely at the mercy of a catalog edited in a different PR. They now fall back to the category, ordered smallest first, when fewer than three curated ids resolve. Ported from Android's pickLLMs, same threshold. This is what turns the simulator's 2-of-5 into a full list, and what would absorb a future catalog pass that renames a family without updating this file.

Tier selection. preferences(for:) collapsed .unknown onto midRange, and HardwareTierResolver.resolve returns .unknown on every device, so one list was the only list anything read. Until commons publishes a typed tier, platform is the one honest signal available: a Mac reads the larger list, a phone does not. Not a RAM heuristic, not a memory budget. A real tier outranks it when it arrives.

Tests. Six cases in ModelRecommendationEngineTests, passing alongside the existing suite. They assert the back-fill property, not specific ids: a catalog where no curated id matches still produces recommendations, back-fill opens with the cheapest option, a false canRun still excludes, and an empty catalog correctly recommends nothing.

Conflicts with #12

This branch and #12 both rewrite the same three curated id lists with different picks, so they conflict. That is how I caught the error above.

Since there is no regression to race, #12 should merge first and this branch should rebase onto it, keeping #12's ids and adding only the back-fill, the tier selection, the org rules, and the tests. I will do that rather than have a reviewer resolve a conflict between two opinions about which models are good. Say the word and I will push the rebase.

Not in this PR

The device ceiling. checkCompatibility(id:) already sends real availableRamBytes and availableStorageBytes and gets a typed canRun back from commons, so this needs no hardcoded 10B/35B cap, only extending ModelCompatibilityLookup from the recommendation path to browse.

The change adds IBM and Deepgrove catalog support, expands model identifier matching, and updates recommendations to use category and compatibility filters with catalog fallbacks. Unit tests cover fallback ordering, empty catalogs, compatibility results, and voice pipeline selection.

Changes

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to d8cf9

The recommendation changes can select an incompatible voice-activity model, which may cause voice features to fail at runtime, and the new Fara publisher classification is inaccurate. The PR is not merge-ready until the compatibility filtering issue is fixed or explicitly accepted; the taxonomy issue should also be corrected.

Resolve the Fara taxonomy mismatch.

"fara" matches only the Fara1.5 catalog row, but the rule assigns it to .microsoft and displays "Microsoft". Use a publisher-neutral classification for Fara.

Filter VAD candidates with canRunByModelID.

Lines 158-159 select the registered VAD and the category fallback without isRunnable. A VAD with a false compatibility verdict can therefore enter the voice pipeline. Use pickFirst for VAD so the registered ID and fallback both apply the compatibility filter.

  • RunAnywhereAI/Features/Models/ModelRecommendation.swift#L158-L159: select VAD through pickFirst(ids: [Self.vadModelID], category: .voiceActivityDetection, from: byID, canRunByModelID: canRunByModelID).
  • RunAnywhereAIUnitTests/ModelRecommendationEngineTests.swift#L111-L124: add a test where "silero-vad" has a false verdict and a runnable VAD fallback is selected.
Proposed fix
-            vad: byID[Self.vadModelID]
-                ?? byID.values.first { $0.category == .voiceActivityDetection }
+            vad: pickFirst(
+                ids: [Self.vadModelID],
