Head-to-head comparison
Nex-N2-Mini (Nex AGI) and GLM 5.3 (Z.ai) compared on the ModelCap Index, API price, context window, provider availability, weight access and every public benchmark board they share. Figures are the same ones shown on the live rankings; nothing here is a hidden score.
Snapshot as of 19 August 2026
As of 19 August 2026, GLM 5.3 holds the stronger ModelCap Index position (#7 vs #25); Nex-N2-Mini is 44× cheaper per output token ($0.10/1M vs $4.40/1M); GLM 5.3 offers the longer context window (1M vs 262K tokens); and Nex-N2-Mini ships open weights.
Evidence: start rank interpolated from the launch card's own comparison table against resolved catalogue peers, discounted for measured cross-lab optimism · 1 public benchmark observation across 1 board. Prices are the lowest listed API offer per million tokens observed on the OpenRouter catalogue.
Scores are the sources' own published figures for each model's best evaluated configuration; ModelCap never re-runs a benchmark.

GLM 5.3 ranks higher on the ModelCap Index as of 19 August 2026: #7 against #25. That is a capability ranking built from public benchmark evidence with published uncertainty; whether it is "better" for you also depends on price, context and where you can run it.
Nex-N2-Mini is cheaper on output tokens: $0.10/1M against $4.40/1M. Input tokens are $0.025/1M for Nex-N2-Mini and $1.40/1M for GLM 5.3. Prices are the lowest listed API offer ModelCap observed, in USD per million tokens.
GLM 5.3 has the larger context window: 1M tokens against 262K.
The two models do not share a coding benchmark board on ModelCap yet, so no head-to-head coding score is published; the ModelCap Index position is the closest overall signal.
Nex-N2-Mini: Open weights. GLM 5.3: API only. Open weights mean the checkpoint can be downloaded and self-hosted under its licence; API-only models are available solely through hosted endpoints.
ModelCap currently lists 1 API provider for Nex-N2-Mini and 1 for GLM 5.3, from the OpenRouter catalogue snapshot the site serves; each model page lists the providers and their prices.
Every figure comes from the sealed ModelCap dataset published 19 August 2026; the page re-renders within a minute of each data refresh, and the ModelCap Index positions are the same ones shown on the live rankings.
