      "paragraphs": [
        "On November 12, 2024, Qwen announced the Qwen2.5-Coder series. The launch post said the release added 0.5B, 3B, 14B and 32B models to previously released 1.5B and 7B sizes, producing six mainstream size points. It described code-assistant and artifact scenarios and made performance comparisons for Qwen2.5-Coder-32B-Instruct.",
        "A six-size release should not be reported as one unit of capability. Memory, latency, context handling, quantisation options and tool behaviour can vary sharply across a family and runtime. The supplier’s comparisons are useful as stated test evidence, but they do not predict a model’s output on another repository or task."

      "paragraphs": [
        "A local coding harness names the repository revision, task statement, files supplied, tools permitted, command timeout, model revision, sampling settings and pass rule. It stores the patch and command results. This makes it possible to compare a small model with a larger one on the work that matters, rather than treating parameter count or a public leaderboard as a deployment answer.",
        "Include negative cases: a task that lacks required information, a request to alter an unrelated file, a failing test and a risky command. The model should surface uncertainty or stop when it lacks authority. A completion that compiles while widening scope, dropping an access check or editing an unowned file is not an accepted result."

      "paragraphs": [
        "An artifact or generated application can be a useful way to explore an interface. It still needs a source boundary, dependency review, test suite, licence check and release owner. Do not let a generated preview obscure which code will be shipped or which service receives user data. Pin the build and retain a diff from the accepted source revision.",
        "For an assisted coding workflow, separate suggestion from execution. A model can propose a patch and explain its tests; a human or deterministic gate should verify the actual files and commands. This is original engineering analysis, not a statement about Qwen tooling or licences."

        "The operational conclusion is bounded: choose a coding model with a fixed task harness and accept a patch only after its actual evidence passes. Keep compiler, linter and test versions fixed during comparison, or report a toolchain change as a separate cause of result variation. Measure human review time, because it is part of the cost of an assisted code path. Log the rejected patch reason too."
