Z.ai: GLM 5.3
z-ai/glm-5.3About this API
GLM-5.3 is a large-scale reasoning model from Z.ai, built for complex software engineering and long-horizon agent tasks. It supports text input and output with a 1M-token context window, and improves...
Provider-supplied description, not an independently validated performance claim.These are the catalogue’s token tariffs. Image, audio, video, search and other charges may use different billing units. Zero token rates alone do not mean those services are free. See the complete pricing fields below and the source model page.
- The published 1,310,720-token context window can accommodate larger inputs, subject to gateway limits.
- No separate per-request fee is listed in this catalogue observation. Other modality charges may apply.
- The upstream catalogue advertises tool-call parameters. This gateway does not expose them yet.
- Published input token pricing is above the median of catalogue entries with the same output modalities and known tariffs.
- Published output token pricing is above the same-modality catalogue median.
- Trident Protocol currently limits requests to text content, 24 KB of conversation and at most 4,096 output tokens. Free variants remain subject to upstream rate limits and availability.
- No independent latency, uptime, reasoning-quality or coding benchmark has been measured by this application.
Assessment uses published fields and unweighted price medians across 426 entries with the same output modalities and known tariffs. It is a cost-and-capability comparison, not a quality ranking or recommendation.

One catalogue observation per hour. History begins when this deployment first observes the model. No backfilled or interpolated prices.
Zero baseline. Published token tariffs, not total multimodal cost or performance scores.
