GLM-5.3

GLM-5.3 by zhipuai is offered by 82 providers on this page. Public prices are shown for 71 of them. Its official list price is $1.40 per 1M input tokens and $4.40 per 1M output tokens. The lowest paid channel is CrofAI at $0.40 / $1.40 per 1M, about 7.0× below the list price. That channel is a third-party gateway, so confirm its availability and rate limits before depending on it. It also has 3 free ($0) channels and 7 covered by a paid subscription; free tiers usually carry rate limits, and subscription-covered access bills $0 per token only after the subscription fee.

Artificial Analysis rates it 44.8 on the Intelligence Index, with 74.8 for coding and 53.1 for agentic tasks. Against its lowest blended price of $0.65 per 1M, that is roughly 69 index points per dollar, which is the value ratio the leaderboards rank on. Median output speed is 83 tokens per second, with 2.63s to the first token. Running one task of the Artificial Analysis suite costs about $2.0056, which reflects how many tokens its reasoning consumes rather than the unit price alone.

The context window is 1,000,000 tokens at the reference host, but hosts report different limits, from 327,680 to 1,049,000, so the usable window depends on the provider you pick. It supports reasoning, tool use, and structured output. Accepted input modalities are Text and Image. The weights are open, so it can also be self-hosted or served through a gateway of your choice. Providers report the capability flags inconsistently, so verify a specific feature against the host you plan to use.
