Community results shared this week ran GLM-5.3 and GLM-5.3-Flash from Z.ai through five coding agent harnesses on the 30 [FrontierHarness](https://frontierharness.org) tasks. Z.ai's own harness, ZCode, came out on top, and was the only one run on Flash. We ran Mouse on GLM-5.3-Flash on the same tasks. It passed 23 of 30, at $0.29 per pass.

GLM and DeepSeek rows are third-party local runs at list prices on observed cache. Mouse rows are Runta runs under FrontierHarness's scripts.

FrontierHarness tasks, pass rate against total recorded cost divided by passes. Different models, providers, and runtimes: a side-by-side, not a controlled ranking.

 

## The comparison

The published FrontierHarness board fixes the model at Kimi K3. The GLM results are a separate, community-run extension: the same 30 tasks and scoring, with GLM-5.3 on a Zhipu Max plan instead. Cost is observed tokens multiplied by Z.ai's API list price, not what the plan bills. ZCode was run three times per model, so its rows are averages.

| Harness | Model | Pass rate | Passed | $ / pass | Runs |
| --- | --- | --- | --- | --- | --- |
| ZCode | GLM-5.3 | 82% | 24.67/30 | $1.98 | 26 / 22 / 26 |
| Claude Code | GLM-5.3 | 80% | 24/30 | $2.58 | 1 |
| Mouse | GLM-5.3-Flash | 77% | 23/30 | $0.29 | 1 |
| ZCode | GLM-5.3-Flash | 76% | 22.67/30 | $0.15 | 24 / 21 / 23 |
| Codex | GLM-5.3 | 67% | 20/30 | $1.19 | 1 |
| Pi | GLM-5.3 | 60% | 18/30 | $2.10 | 1 |
| OpenCode | GLM-5.3 | 47% | 14/30 | $2.28 | 1 |

On Flash, Mouse's single run (23) sits within ZCode's three runs (24, 21, and 23). ZCode is cheaper per pass, $0.16 against Mouse's $0.29. On the full GLM-5.3 model, ZCode and Claude Code pass 24 to 25 tasks and cost $2 to $2.60 per pass, so Mouse on Flash comes within one or two tasks of them at a seventh to a ninth of the cost per pass.

## Against Kimi K3

The same harness scored 25 of 30 on Kimi K3 at $2.79 per pass. Flash lost two tasks that K3 passed, both DeepSWE: `expr-try-catch-errors` and `fastapi-deprecation-response-headers`. It did not pass anything K3 failed. The other five misses were shared: `meriyah` on DeepSWE, and `dna-insert`, `polyglot-c-py`, `extract-elf`, and `gcode-to-text` on Terminal-Bench.

The cost difference is mostly the model's price. Flash lists at $0.15 per million input tokens, $0.03 cached, and $0.50 output. Cache hits covered 96.7% of input tokens, so the median passing task cost a little over a cent. The DeepSWE tasks were most of the bill: the nine of them cost $6.10 of the $6.72.

## How the run was made

- FrontierHarness's own trial driver, unmodified, at their eval commit `e837a70`, on Runta with a fresh restore for every task and 4 vCPU / 8 GiB per task. Terminal-Bench through Harbor 0.22.0, DeepSWE through Pier 0.3.1.
- Harness commit `315e2b8` on OpenCode 1.18.27, the same checkpoint as the Kimi K3 run, with only the model changed: `glm-5p3-flash` served by Fireworks.
- Cost is each trial's observed tokens at Z.ai's GLM-5.3-Flash list price, which Fireworks matches. Three attempts on two tasks hit Ubuntu mirror errors while setting up the container, before the model ran; they were re-run and are not counted as failures.
- One run, 2026-09-14. The other rows were run locally by a third party, on a different provider, runtime, and harness versions (Claude Code 2.1.237, OpenCode 1.18.19, Codex 0.148.0, Pi 0.84.2), so this is a side-by-side, not a controlled ranking.

GLM results for ZCode, Claude Code, Codex, Pi, and OpenCode are from a community comparison shared this week, building on work by LotusDecoder. Mouse is built on [OpenCode](https://github.com/anomalyco/opencode) and is not affiliated with it or with Z.ai.

Interpretation history

• 2026-09-27T13:33:57Z
  The episode is over: the only new attachment (TensorSharp/Jev multimodal endpoint) is unrelated to GLM-5.3, and six weeks past release engagement sits at ~0.5 pts/h against a 69 pt/h peak — the magnitude flag reflects the September announcement/weights wave, not current activity. The independent-evaluation question the case was tracking is settled: coding frontier-adjacency is corroborated across AA, Terminal-Bench v4 and FrontierHarness, while the cyber-superiority claim never won independent confirmation, so it resolves as absorbed.

  The FlashX attachment supplies only a headline claiming 200 tokens/s, not the first-party serving artifact described by the attachment rationale. Without model identity, serving conditions, access terms or inspectable results, it does not establish improved agent throughput or change the coding and cybersecurity assessment.

  evidence attached: reddit.post.1wh8h88 — Offers weak user-level evidence of GLM-5.3 performance inside the DeepSeek harness, but the image-based anecdote is not an independent evaluation.
• 2026-09-15T00:26:00Z
  Mouse adds a methodologically specified coding-agent run that strengthens GLM-5.3-Flash's case as a low-cost evaluation candidate, moving beyond benchmark headlines to task-level outcomes and token accounting. The result is single-run and cache-dependent, not proof of cross-harness superiority, production economics, or stronger cybersecurity.

  The reported $37 red-team exercise adds a specific practical cyber lead: two bugs allegedly found outside an Alloy-modeled authentication layer, which reportedly held. This modestly strengthens evidence of useful security-review work, but title-only testimony establishes neither the bugs’ security impact nor comparative capability gains, and does not validate the authentication layer’s general security.

• 2026-09-06T13:24:14Z
  A second user's claimed long-context testing makes the regression concern more specific: strong initial answers followed by multi-turn degradation and weak system-prompt adherence. This modestly strengthens the reliability-testing lead but, without prompts, serving details or comparative outputs, does not establish regression or overturn independent coding benchmarks; practical cybersecurity capability remains provisional.
• 2026-09-06T11:27:54Z
  Refreshed comments recommend controlled comparisons and speculate about free-tier quantization; neither establishes a serving change or reproducible regression. Independent coding benchmarks remain supportive, while practical agent reliability and stronger cybersecurity capability remain unresolved.

• 2026-08-15T13:31:38Z
  The refreshed discussion and minor engagement changes add no independent coding evaluation, reproducible OpenVuln results, attributable vulnerability disclosure, or verified linkage between GLM-5.3 and the portal findings. OpenVuln remains an inspectable first-party implementation surface, but the case is still a cold validation episode awaiting external evidence.
• 2026-08-15T12:30:38Z
  OpenVuln moves the cyber claim from announcement and portal counts to a concrete first-party implementation surface, making follow-on inspection possible. It still provides no independently verified findings, reproducible methodology, or coding evaluation, so it does not establish GLM-5.3’s claimed capabilities.
• 2026-08-15T12:22:30Z
  evidence attached: hn.story.49309938 — The OpenVuln release is a concrete first-party artifact showing GLM-5.3 applied to open-source vulnerability auditing, though model claims remain unverified.
• 2026-08-15T11:40:57Z
  The refreshed discussion remains repetitive and anecdotal, with no independent coding evaluation, usable weights, attributable vulnerability disclosure, or verified connection between GLM-5.3 and the portal findings. The case remains a cold validation episode awaiting inspectable evidence.
• 2026-08-15T10:30:50Z
  The refreshed discussion remains anecdotal and repetitive, adding no independent coding evaluation, usable weights, attributable vulnerability disclosure, or verified link between GLM-5.3 and the portal findings. The case remains a cold validation episode pending inspectable external evidence.
• 2026-08-15T09:29:20Z
  The refreshed comments add only another anecdotal security-research experience and continued release enthusiasm, not an independent GLM-5.3 coding evaluation, usable weights, attributable vulnerability disclosures, or verified linkage to the CVD results. The case remains a cold validation episode awaiting inspectable evidence.
• 2026-08-15T07:29:46Z
  Z.ai’s new first-party post clarifies that the open-weight release is still being prepared behind cyber-safety evaluation and hardening, rather than providing weights or inspectable results. Independent coding validation and attributable cyber findings remain absent, so the case’s core hypothesis has not advanced.
• 2026-08-15T07:22:21Z
  evidence attached: hn.story.49308243 — Z.ai's first-party announcement materially updates the open-release and cybersecurity-capability hypothesis, though independent validation remains pending.
• 2026-08-15T06:49:53Z
  The newly attached article is secondary positioning rather than an independent evaluation: no benchmark outputs, trace-backed coding runs, attributable disclosures, or verified GLM-5.3 cyber results are visible. It therefore does not supply the second evidentiary line needed for corroboration.

• 2026-08-15T04:26:20Z
  The refreshed discussion adds no independent coding evaluation, usable weight implementation, attributable vulnerability disclosure, or verified link between GLM-5.3 and the portal findings. This remains repetitive amplification rather than validation, so the case stays cold despite hot adjacent topics.
• 2026-08-15T01:25:13Z
  The refreshed HN discussion adds no independent evaluation, released-weight implementation, attributable vulnerability disclosure, or verified connection between GLM-5.3 and the portal findings. This is continued amplification rather than validation, so the case remains cold pending substantive external evidence.
• 2026-08-15T00:24:19Z
  The refreshed discussion adds no independent coding evaluation, released-weight implementation, attributable vulnerability disclosure, or verified GLM-5.3 link to the portal findings; it is repetitive amplification rather than validation.
• 2026-08-14T23:29:35Z
  The refreshed discussion remains repetitive amplification of the release and vulnerability-count claims, without an independent coding evaluation, usable weight test, attributable disclosure, or verified GLM-5.3 connection. The case remains a cold validation episode awaiting substantive external evidence.
• 2026-08-14T22:32:14Z
  The refreshed comments remain repetitive amplification and speculation, adding no independent coding-harness result, usable weight test, attributable vulnerability disclosure, or verified connection between GLM-5.3 and the portal findings. The case remains a cold validation episode awaiting substantive external evidence.
• 2026-08-14T21:25:37Z
  The refreshed comments remain repetitive amplification and skepticism, with no independent coding-harness result, released-weight test, attributable vulnerability disclosure, or verified link between GLM-5.3 and the portal findings. The case remains cold despite high surrounding topic heat.
• 2026-08-14T20:41:55Z
  Refreshed comments add only an unattributed anecdote about security-research performance and further amplification of existing claims. There is still no independent coding evaluation, released-weight test, named vulnerability disclosure, or verified attribution of the portal results to GLM-5.3.
• 2026-08-14T19:47:36Z
  Refreshed comments and minor engagement growth only repeat enthusiasm, skepticism, and the existing vulnerability-count claim. No independent coding evaluation, released-weight test, named disclosure, or verified GLM-5.3 attribution changes the case’s meaning.
• 2026-08-14T18:41:05Z
  The refreshed discussion adds no independent coding evaluation, released-weight test, named vulnerability disclosure, or verified attribution of the portal results to GLM-5.3. This remains a cold validation episode despite the surrounding topics staying hot.
• 2026-08-14T17:42:12Z
  The refreshed comments remain repetitive amplification of release claims and the unverified vulnerability count; no independent coding evaluation, named disclosure, released-weight test, or GLM-5.3 attribution changes the case’s meaning.
• 2026-08-14T16:38:20Z
  The refreshed discussion remains repetitive amplification and anecdotal enthusiasm, without independent coding evaluations, named vulnerability disclosures, or evidence linking the portal results to GLM-5.3. The case remains open but cold pending substantive validation or released weights.
• 2026-08-14T14:24:32Z
  The refreshed comments add only further amplification and anecdotal enthusiasm, with no named disclosures, independent harness results, or verified link between GLM-5.3 and the portal’s vulnerability count. The validation episode remains open but is now cold pending substantive external evidence.
• 2026-08-14T13:37:37Z
  Refreshed comments merely amplify the existing vulnerability-count claim and local-model speculation; they add no named disclosures, independent validation, or evidence tying the CVD portal’s findings to GLM-5.3. The case remains a live validation episode without substantive advancement.
• 2026-08-14T12:33:08Z
  The case now has a concrete field-performance claim—2,436 unpatched open-source vulnerabilities reportedly surfaced through Z.ai’s disclosure portal—rather than benchmarks alone. It remains a single derivative report without attributable disclosures, independent verification, or a demonstrated link to GLM-5.3, so it does not yet qualify as corroboration.
• 2026-08-14T12:22:43Z
  evidence attached: reddit.post.1vo56qy — The report provides potentially relevant field evidence that GLM 5.3 can discover large numbers of real open-source vulnerabilities, though the claim still needs verification.
• 2026-08-14T11:31:06Z
  The refreshed discussion only repeats the previously identified CVD portal lead and broader speculation; it adds no attributable vulnerability disclosures, independent coding-harness results, or evidence tying operational cyber findings to GLM-5.3. The validation episode remains open but has not substantively advanced.
• 2026-08-14T10:35:12Z
  A refreshed HN comment introduces a concrete, externally checkable claim that Z.ai is using its cyber capability to scan open-source software and coordinate vulnerability disclosures through a public CVD portal. This advances the case beyond repetitive benchmark discussion, but the operational results and their connection to GLM-5.3 remain unverified.
• 2026-08-14T09:27:47Z
  Refreshed comments remain speculative and repetitive, adding neither an official weight artifact nor independent coding-harness or cybersecurity results. The release still defines a validation episode, but its substantive meaning has not advanced.
• 2026-08-14T08:41:38Z
  The newly attached Reddit post does not establish that GLM-5.3 weights are available; it only anticipates local and quantized performance, while other evidence says the weights are forthcoming. The case remains vendor-claimed and awaits an official weight artifact plus independent coding-harness and cybersecurity evaluations.
• 2026-08-14T08:22:26Z
  evidence attached: reddit.post.1vo0r4w — The released GLM-5.3 weights provide direct first-party evidence for the open model-validation case, though performance remains untested.
• 2026-08-14T07:24:01Z
  Refreshed discussion remains repetitive amplification of the release, with no independent coding-harness results, implementation reports, or practical cybersecurity validation. The case stays open but cools until substantive evaluation evidence arrives.
