GLM-5.3-Flash native Linux migration evidence¶
Campaign 2026-09-08-glm53-linux-wsl-comparison measures the existing model on
two RTX PRO 6000 Blackwell Max-Q GPUs against retained Windows/WSL evidence.
Launcher revision: 8abcc5dc75a1b2389210b553120abb76e5864d3a, initially clean
tracked worktree; campaign changes are documentation and evidence only.
The dated finding explains the
bounded functional, capacity and quality results and no-promotion decision.
Campaign controls¶
- Artifact manifest: native schemas, ten roles, exact hashes and bytes.
- Decision summary, coverage and gaps.
- Source registry, workload manifest, plan, reproduction.
- Exact configuration, native contract, hardware, launcher.
- Failures and dispositions, restoration, sanitization.
- Campaign state, publication assignment, publication summary.
Native measurements¶
| Population | Retained native evidence | Interpretation |
|---|---|---|
| Direct disabled/off | Full gate, smoke | General-image exact phrase failed; other nine checks passed |
| Direct enabled/on | Functional gate, control index | Reasoning evidence present with separate diagnostic budget |
| Historical-style C1 n3 | 4K, 120K, 262K, 380K | Warm online direct, shared prefixes, variable short output; descriptive medians |
| Retained WSL C1 n3 | 4K, 120K, 262K, 380K | Matching original native bytes; no new Windows arm |
| Strict output | Scout | 0/3 exact128-word compliance; all performance withheld |
| Unique natural answer | 4K diagnostic | 1/10 first-position canary compliance; dependent depths not run |
| Coding | Quality | Five deterministic cases x3, 15/15 |
| Images | Corpus | Six cases x2, 12/12; native multimodal schema retained |
| Endurance | Linux, WSL | 60/60 each; same variable-output/shared-prefix limitations |
| Routed acceptance | Disabled, 260K retrieval, enabled | 380K estimate rejects413; reasoning projection evidence fails; visible answers otherwise correct |
| Deep agentic | Native job, 30 observations | 30/30 endpoint-only co-resident cases |
| Extended context | Native job, summary | 128/150; 9 empty and 13 incorrect; default thinking, no Windows control |
| SWE smoke | Native job, official grader stage, comparison | Same one instance resolves1/1; new trajectory is slower and longer |
Derived views and boundaries¶
Comparison data, prompt equivalence, graph manifest, graph data, and context comparison chart trace the historical comparison to native request artifacts. The separate endurance chart, manifest and data compare the n=60 populations. Both chart packs are embedded in the finding; repeated graph renders are byte-identical.
Capacity artifacts retain anvil-serving.benchmark/v1; durable jobs retain
anvil-serving.benchmark-evidence/v1; image evidence retains
multimodal-benchmark-evidence/v1. Preflight and coding retain their native
contracts. Failed and partial populations remain visible. Console logs in this
bundle record CLI failures and summaries; native JSON is authoritative.
The migration also changes the driver, transport and cache history. Decode improvements are whole-stack descriptive results, not an OS-only causal result or a strict controlled-output qualification. p99 at n3/n60 is descriptive only. No speculation A/B, video qualification, higher engine concurrency, full SWE score, model promotion or client-catalog change is claimed.
