Z.ai Launches GLM-5.3 API Scoring 60 on Index
Z.ai released the GLM-5.3 API optimized for coding and agentic work at the same price as GLM-5.2.
TLDR
Z.ai made the GLM-5.3 API available for coding, defensive cybersecurity, and long-horizon agentic tasks. The model reaches 60 on the Artificial Analysis Intelligence Index, matching Kimi K3 and rising 7 points from GLM-5.2. Artificial Analysis recorded gains on AA-Omniscience from 4 to 14 and accuracy from 23 percent to 34 percent. On the GDPval-AA v2 benchmark the score rose 246 Elo points to 1770. The API is live through the official endpoint and partner gateways. Weights remain unreleased.

AA Artificial Analysis@ArtificialAnlysGLM-5.3 achieves 60 on the Artificial Analysis Intelligence Index, on par with Kimi K3 and up 7 points from GLM-5.2. Once the weights are released it will be tied as the leading open weights model @Zai_org has just launched GLM-5.3, which ties Kimi K3 (60) for the most…

ZE Zephyr@zephyr_z9Scaling the performance of a 700B model is pretty insane All the other models are 2x-4x larger than this https://twitter.com/ArtificialAnlys/status/2089830890709135426

T( Teortaxes▶️ (DeepSeek 推特🐋铁粉 2023 – ∞)@teortaxesTexAnd 0731 is 3x smaller than GLM-5, while matching (sometimes beating!) GLM 5.2. And it's not saturated yet. I think Flash-next will match GLM 5.3. It's time we talk AGAIN about the wisdom of parameter scaling. All this buzz about "10T mythos class" is juvenile. Clearly a 1T…
