Summary models: fast vs large (#225)¶

50 openly licensed articles from tests/fixtures/real_pages, summarized by openai/gpt-oss-20b (fast) and openai/gpt-oss-120b (large) with the production prompt. Generated by backend/scripts/summary_spot_check.py on 2026-10-21, with LLM_REASONING_EFFORT=auto.

Status: all 50 articles run. The fast model has no result for the last 9 (wikipedia-10 to rust-13) because Groq's free daily token cap for gpt-oss-20b ran out: Groq asked to retry after 15 to 29 minutes, and the client doesn't wait that long (#225). These are not quality failures.

On the 41 articles both models completed: valid JSON 41/41 for both; headline of 15 words or fewer: fast 41/41, large 40/41; brief of 2 to 3 sentences: fast 40/41, large 41/41; topics 41/41 for both. The fast model is as reliable as the large one for summaries, so the defaults stay: summaries and topics on LLM_MODEL_FAST, story synthesis on LLM_MODEL_PRIMARY (per-task settings in Deployment).

Still to do: a person fills in the Better column below; then #225 closes.

wikipedia-01: https://en.wikipedia.org/wiki/Garbage_collection_(computer_science)¶

Fast: Garbage collection automates memory cleanup, trading programmer effort for runtime overhead. Garbage collection (GC) automatically reclaims memory no longer referenced, easing developer burden but adding computational cost. It originated with John McCarthy in 1959 for Lisp and now underpins many languages such as Java, C#, Go, and Python. While GC prevents errors like dangling pointers and double frees, it can cause unpredictable pauses and higher memory usage, prompting alternatives like reference counting, escape analysis, and manual memory management.

Fast: Rust’s safety guarantees ease high‑criticality development but ecosystem gaps slow adoption. The article surveys safety‑critical teams across automotive, aerospace, medical, and industrial domains, noting that Rust’s compiler‑enforced safety reduces manual review and aligns with standards like ISO 26262. However, ecosystem support—such as lack of Rust‑compatible RTOSes, tooling for certification, and stable dependency management—creates friction when moving beyond prototyping into higher integrity levels. The piece recommends coordinated industry‑Rust Project collaboration, MSRV conventions, target‑tier checklists, and safety‑case‑friendly async runtimes to bridge these gaps.
Large: Rust gains traction in safety‑critical software but ecosystem gaps hinder high‑integrity adoption. The article reports that Rust is already deployed in production safety‑critical systems across automotive, medical, and industrial domains, offering compiler‑enforced safety that replaces many manual checks.

Fast: Use Go generics only when identical code repeats across types. The article explains when to employ generics in Go 1.18, emphasizing that generics should be used when the same logic applies to multiple types, such as functions operating on language-defined containers or general-purpose data structures. It advises against replacing interface types with generics for speed or when method implementations differ, and recommends reflection for truly heterogeneous operations. The key takeaway is to write code first, then add type parameters only if identical code is duplicated.

wikipedia-03: https://en.wikipedia.org/wiki/Just-in-time_compilation ¶

Fast: JIT compilation blends speed of native code with flexibility of interpretation. Just‑in‑time (JIT) compilation translates bytecode to machine code during program execution, enabling adaptive optimizations such as inlining and CPU‑specific instruction selection. Historically pioneered by LISP and Smalltalk, JIT became mainstream with Java’s HotSpot and is now common in Java, .NET, PHP, and CPython. While JIT can outperform static compilers, it introduces startup latency and security concerns around executable memory.

Fast: Kubernetes v1.37 will enable SELinuxMount by default, speeding volume setup but risking pod conflicts. Kubernetes plans to turn on the SELinuxMount feature gate in v1.37, which will mount volumes with SELinux context directly, eliminating the costly recursive relabeling. However, this change can break workloads that rely on the older recursive model, especially when privileged and unprivileged pods share a volume or when pods use different subpaths. Administrators are advised to audit clusters on v1.36, enable the selinux-warning-controller, and resolve conflicts before upgrading.
Large: Kubernetes v1.36+ will default‑enable SELinuxMount, speeding mounts but breaking shared‑volume setups. The article warns that Kubernetes will enable the SELinuxMount feature gate by default in an upcoming release (v1.37), making volume mounting faster by applying SELinux labels at mount time. However, this change can break workloads that rely on recursive relabeling, such as pods sharing a volume with different SELinux labels or privileged/unprivileged pods sharing a volume. It advises auditing clusters in v1.36 and using new controls to opt‑out or resolve conflicts before upgrading.

Fast: Kubernetes v1.36 Adds Watch‑Based Route Sync Metric to Reduce API Calls. Kubernetes v1.36 introduces a new alpha metric, route sync total, to track how often the Cloud Controller Manager’s route controller syncs routes with the cloud provider. The metric supports the CloudControllerManagerWatchBasedRoutesReconciliation feature gate, which switches the controller from a fixed‑interval loop to a watch‑based approach that only reconciles on node changes. Operators can A/B test the feature gate by comparing sync counts with the gate disabled versus enabled, expecting a significant drop in syncs in stable clusters.

wikipedia-05: https://en.wikipedia.org/wiki/Raft_(algorithm)¶

Fast: Raft offers a clear, formally safe alternative to Paxos for crash‑fault tolerant consensus. Raft is a consensus algorithm that simplifies Paxos by separating logic and providing formal safety proofs. It uses a single elected leader for log replication, ensuring all nodes agree on state transitions. While not Byzantine fault tolerant in its base form, variants with cryptographic signatures exist. The algorithm includes mechanisms for leader election, log compaction, and joint consensus for membership changes, but suffers from a leader bottleneck and unverified reconfiguration safety.

Fast: Rust 1.82 adopts LLVM 19, enabling WebAssembly reference-types and multivalue by default. The Rust compiler’s upcoming 1.82 release upgrades to LLVM 19, which now defaults the WebAssembly reference-types and multivalue proposals. This change means Rust-generated WebAssembly binaries will use over‑long LEB encodings for indirect calls and may not run on engines lacking reference‑types support, while multivalue has minimal impact on existing Rust code. Users can disable these defaults via Cargo’s build‑std or test with wasm‑opt to shrink binaries.
