GLM-5.3 Smart Index soared to 60: tied with Kimi K3, API unit price did not rise

Comparative news, according to monitoring, Zhi Spectrum officially opened the GLM-5.3 API. Previously, when the model was released, the API was not immediately launched. At the same time, an independent evaluation of Artificial Analysis was released: the Intelligence Index soared from 53 to 60 in GLM-5.2, equalizing Kimi K3, only 1 point below GPT-5.6 Sol. Once the weights are revealed as planned, it will be tied with Kimi K3 as the open weighting model with the highest AA rating. The biggest increase was Agent. GDPVal-aa v2's Elo jumped from 1524 to 1770, rising 246 points at a time, second only to Claude Opus 5's 1855, and over 100 points higher than Kimi K3's 1668. The API unit price did not follow suit. The input is still $1.40 per million tokens, the output is $4.40, and the cache input is $0.26, exactly the same as GLM-5.2. However, 5.3 is clearly more capable of spending tokens. AA measured that it outputs an average of about 18,700 tokens per task, 20% more than 5.2. As a result, the actual cost of a single task rose from $0.44 to $0.68, which was approximately 55% more expensive. Even so, it's still cheaper than the Kimi K3 at $0.84 and the GPT-5.6 Sol at $1.23.
