JSON schema output
Accept a JSON schema to constrain generation; model-dependent correctness must be tested.

Standing condition: these are documentation claims at the source capture date, with outcome “claimed”; no runtime execution is recorded. Dossier applicability and limitations apply throughout. Expand a row for its statement, specific scope and contradictions. Numbered citations resolve to the source locator and capture date below. Missing evidence means Unknown, not No. Sources are unpinned unless marked “Pinned”; this marks source stability, not stronger support or runtime verification. Reuse counts refer to claims in the full dossier; repeated citations do not represent independent sources.
Yes Documented within scope Partial Limited form of the feature No Explicit evidence of absence Unknown No evidence recorded. These are support assessments, not quality scores or runtime verification.
3 products have Yes or Partial documentation. Review freshness and attestation counts describe the dossier, not runtime quality. Gaps below are product-wide, not necessarily specific to this feature.

What we do not know yet about llama.cpp
- Which pinned model, quantization, context length and runtime versions fit the selected Mac?
- What are measured latency, throughput, peak memory and swap under one and four concurrent requests?
Applicability
Repository revision 38a5b42d9a3e82e0a586bcd1caed121f36c87a73; living documentation separately dated.
Self-managed local build and server; pin compiled backends and model files.
Excludes: Runtime verification and performance rankings; Model weights license or quality evaluation; Cloud inference, remote hosts and external tools; Unlisted model architectures, builds and hardware
Recheck when
- Runtime, bundled engine, backend, model format or license changes.
- Documentation changes affecting the cited configuration.
Needs recheck · due
Verification plan
- Choose hardware and obtain explicit approval for installations, downloads and execution resources.
- Pin runtime and engine versions, model artifact hashes, tokenizer, template, quantization and inference settings.
- Run the local-model-mac investigation with synthetic prompts and capture raw measurements; do not record documentation as execution.

What we do not know yet about LM Studio (local runtime)
- Which pinned model, quantization, context length and runtime versions fit the selected Mac?
- What are measured latency, throughput, peak memory and swap under one and four concurrent requests?
