How this price is scoped: Read 2026-09-05 from Together's own serverless-models card (docs.together.ai/docs/serverless-models, the markdown surface the context gate also reads): zai-org/GLM-5.3 at input $1.40 / cached input $0.26 / output $4.40, context 1048575, quantization FP4. The triple is identical to Z.AI's first-party rate and to Fireworks' Standard rate for the same SKU. The 1,048,575-token window is what Together's card lists for THIS endpoint (docs/CONTEXT_WINDOW_CONVENTION.md) — it is Together's served window, not a claim read off the maker.

Deploy this open model on rented GPUs
Open weights mean you can self-host instead of paying per-token API prices. These platforms let you serve it on demand — often cheaper at scale.
Partner links — we may earn a commission if you sign up, at no cost to you. We only list platforms we'd recommend regardless.
Capabilities
struck through = not supportedBenchmark performance
accuracy % · higher is betterWe hold no per-benchmark accuracy scores for this model yet, so it has no accuracy average. That is a gap in our coverage, not a sign the model is untested — independent evaluators often publish a composite index for a new model long before releasing its per-benchmark numbers. The percentile above is its standing across the independent composites below.
- AA Intelligence Index: 48.6 (Artificial Analysis composite across reasoning, knowledge and coding evals)
- AA Agentic Index: 53.6 (Tool use, planning, autonomy)
- AA-Omniscience Index: 14.3 (−100–100)
- GDPval-AA v2: 1680.9 ELO (Real-world work tasks, human baseline = 1000)
- Ranks #8 of 180 comparably-measured models by percentile score, across 4 independent measurements
- Ranks #66 of 180 comparably-tested models by normalized performance per dollar
