The model scores 73/80 (91.25%), placing first ahead of Fable 5, Qwen 3.8 Max, and Opus 4.8/5, and up sharply from GLM 5.2's 75% two months earlier despite identical parameter count and architecture. ZAI highlights a new specialization in security analysis (code auditing, vulnerability discovery) validated with real security teams, paired with an 'open-source shield initiative' that keeps defensive capabilities open while gating high-risk misuse. The reviewer calls out strong performance on both frontend and backend tasks, a notable jump on a previously failed 3D contact-lens-case prompt, and near-best results on a hard 3D wristwatch task. ## Full article daily.dev links to this article rather than hosting it.

GLM-5.3 scores 91.25% (73 out of 80) on the Kingbench 3 benchmark, up from GLM-5.2's 75% roughly two months earlier, despite having the same parameter count and architecture. The jump comes from further post-training rather than architectural changes, with the biggest gains seen in 3D web tasks like a contact lens case prompt that GLM-5.2 previously failed. _Developers tracking open model progress can follow GLM releases and comparisons on daily.dev._ ### What is GLM-5.3's security analysis specialization? GLM-5.3 is specifically trained for code auditing, vulnerability discovery, and security analysis, and has reportedly been used by real security teams to identify risks across developer tools, messaging apps, internet infrastructure, office systems, and robotics. ZAI pairs this with an open-source shield initiative that keeps defensive capabilities open while gating high-risk misuse behind layered safeguards and trusted access. _Teams evaluating AI-assisted code auditing tools can compare options like this on daily.dev._ ### How does GLM-5.3 rank against other top AI models like Fable 5 and Opus 5? On the Kingbench 3 benchmark, GLM-5.3 scored 91.25%, ranking first ahead of Fable 5 (82.5%), Qwen 3.8 Max (81.25%), Opus 4.8 (80%), and both Opus 5 and Kimi K3 (77.5%). It notably beat Fable 5 on individual tasks including a 3D folding table animation and a bow-and-arrow game, though Fable remains preferred for very long-horizon, complex problems. _Developers choosing between frontier and open coding models can track head-to-head comparisons on daily.dev._ ## Similar posts on daily.dev - [GLM-5.3 vs Kimi K3](https://daily.dev/posts/glm-5-3-vs-kimi-k3-xtujtmge7) · Medium · 2 upvotes · 0 comments --- Tags: [#ai](https://daily.dev/tags/ai) [View this post on daily.dev](https://daily.dev/posts/glm-5-3-fully-tested-i-got-early-access-it-s-1-on-my-bench--shcgm5tqp) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"GLM-5.3 (Fully Tested): I GOT EARLY ACCESS & IT'S #1 ON MY BENCH!","url":"https://daily.dev/posts/glm-5-3-fully-tested-i-got-early-access-it-s-1-on-my-bench--shcgm5tqp","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/glm-5-3-fully-tested-i-got-early-access-it-s-1-on-my-bench--shcgm5tqp"},"datePublished":"2026-08-14T05:27:17.591Z","dateModified":"2026-08-14T11:11:46.561Z","description":"An early-access review of GLM-5.3, ZAI's newest open model, run through the reviewer's personal Kingbench 3 benchmark suite covering coding, 3D simulations,...","image":"https://i.ytimg.com/vi/iMpBNN-0-Ss/sddefault.jpg","thumbnailUrl":"https://i.ytimg.com/vi/iMpBNN-0-Ss/sddefault.jpg","isAccessibleForFree":true,"articleSection":"AICodeKing","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"AICodeKing","logo":"https://media.daily.dev/image/upload/s--x7nDUfWj--/f_auto,q_auto/v1768208312/logos/aicodeking","url":"https://daily.dev/sources/aicodeking"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/glm-5-3-fully-tested-i-got-early-access-it-s-1-on-my-bench--shcgm5tqp","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"ai","timeRequired":"PT7M","video":{"@type":"VideoObject","name":"GLM-5.3 (Fully Tested): I GOT EARLY ACCESS & IT'S #1 ON MY BENCH!","description":"An early-access review of GLM-5.3, ZAI's newest open model, run through the reviewer's personal Kingbench 3 benchmark suite covering coding, 3D simulations,...","thumbnailUrl":"https://i.ytimg.com/vi/iMpBNN-0-Ss/sddefault.jpg","uploadDate":"2026-08-14T05:27:17.591Z","duration":"PT7M","url":"https://api.daily.dev/r/shCgm5TqP","embedUrl":"https://www.youtube.com/embed/iMpBNN-0-Ss"}} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"AICodeKing","item":"https://daily.dev/sources/aicodeking"},{"@type":"ListItem","position":3,"name":"GLM-5.3 (Fully Tested): I GOT EARLY ACCESS & IT'S #1 ON MY BENCH!"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/glm-5-3-fully-tested-i-got-early-access-it-s-1-on-my-bench--shcgm5tqp#faq","mainEntity":[{"@type":"Question","name":"How does GLM-5.3 compare to GLM-5.2 in benchmark performance?","acceptedAnswer":{"@type":"Answer","text":"GLM-5.3 scores 91.25% (73 out of 80) on the Kingbench 3 benchmark, up from GLM-5.2's 75% roughly two months earlier, despite having the same parameter count and architecture.
