Structured rows reported in this exact model repository at the pinned revision below. They are the publisher talking about itself: never measured evidence, never a score input on their own. They remain quarantined until dataset revision, harness, configuration and identity pass ModelCap’s independent admission review.
BES normalizes admitted public benchmark evidence for measured Index rows. Its legacy score and observables prior do not define the public language rank.
These adoption and deployment observations remain context only. They do not change this model's ModelCap Index score or rank.
The bounded 0–100 capability score blends each source’s competitive placement with its published achievement, then combines capability families. Evidence breadth adds a modest uncertainty adjustment; price and popularity are not part of benchmark-led rank.
Not yet published: the base model it derives from, a link to the licence terms, pinned evaluation dataset versions.

GLM 5.3 holds ModelCap Index position #11 of 280 ranked language models as of 2 October 2026, with an Index score of 80.0 (interval 74.0–86.0); evidence: measured. The Index combines public benchmark boards with published uncertainty; the methodology page explains the weighting.
GLM 5.3 is listed at $1.40 per 1M input tokens and $4.40 per 1M output tokens as of 2 October 2026; the lowest output price among 32 providers is $0.488 on Baidu. Prices come from the OpenRouter catalogue and re-observe on every refresh. For 1,000 requests using 2,000 input and 500 output tokens each, the listed rates imply $5.00 total (2M input + 0.5M output). This excludes caching, batch discounts, prompt-length tiers, tool charges and retries; verify the chosen endpoint's rate and limits before budgeting.
GLM 5.3 has a published context window of 1M tokens (1,048,576). The snapshot lists a 131,072 token catalogue-declared route output cap. OpenRouter catalogue or provider-endpoint declaration.
