Dates beside benchmark scores refer to the linked source’s publication or capture date unless that source explicitly states when it measured the result. A shared URL alone does not establish comparable runs; unverified setups are marked. Prices are USD per million tokens at standard rates, excluding batch and caching discounts. Values we could not confirm from the provider are shown as “Not verified” rather than estimated.

Pricing tiers

Amazon Nova 2 Pro: Bedrock Global Standard $1.25/$10 per MTok; single-region $1.375/$11. Global Flex/Batch $0.625/$5 and regional $0.6875/$5.50. Global Priority $2.1875/$17.50 and regional $2.40625/$19.25. These are native Nova 2.0 Pro on-demand meters in the complete offer published October 16, 2026, with October 1 effective dates; not custom-model, provisioned-throughput or training prices. No Pro cached-input meter is present in this capture. Billing meters do not establish GA or account access.

Amazon Nova 2 Pro

Amazon's closed Nova 2 Pro preview accepts text, images, video and speech and generates text; its launch announcement specifies a one-million-token context.

Best for

  • AWS-native workloads
  • Multimodal
  • Long-context

Watch out

Preview access was announced for Nova Forge customers through their AWS account team. Current account access, a stable API model ID and a hard output cap remain unverified. Launch documentation names low/medium/high thinking; the current detailed thinking guide covers Lite only, so do not transfer its request rules to Pro. The October 1 Artificial Analysis 14-point Pro row is an estimate and is withheld. Omission from a current model list does not prove retirement.

GLM 5.2

The previous GLM text-only generation, available as an MIT-licensed checkpoint and documented token-API model; GLM-5.3 uses the same base with newer post-training.

Best for

  • Open-weight deployments
  • Reasoning
  • Cost-sensitive work

Watch out

Previous text-only generation; GLM-5.3 uses the same base with newer post-training, but direct token-API identity, Coding Plan routing and native weights remain separate. Current thinking docs accept none/minimal/low/medium/high/xhigh/max: none/minimal stop thinking, low/medium map to high, xhigh maps to max (default). These are not seven independent compute tiers. Exact total/active parameter counts remain unverified; shared-base wording alone is insufficient.

When the cheaper one wins

GLM 5.2 is cheaper on output at $4.40 per million tokens against $10 for Amazon Nova 2 Pro — about 2.3×. Use the cheaper tier for classification, extraction, summarisation, and any task where the expensive model’s extra score does not change the accepted output. The expensive one only pays if your hardest task actually fails on the cheap tier. This compares standard short-context token rates, not total cost per accepted task. Include input, cache, context tiers, schedules, retries and review in your pilot.

Evidence confidence: Medium

How strong and complete the evidence behind this comparison is — not a prediction of which model is better.

  • Pricing verified on both sides — Input and output rates are verified for both models.
  • 3/5 core specs verified on both sides — Not published for at least one side: max output, parameter count.
  • No directly aligned benchmark setup — No benchmark has matching cited sources, source dates, units, effort and recorded run details on both models.
  • Verified within the last 90 days — Older of the two catalog checks was 1 day ago.
  • Both models carry source citations — Each side has at least two catalog sources on record.

Which has the larger context window, Amazon Nova 2 Pro or GLM 5.2?
Both accept about 1M tokens of context, so document length will not decide between them.
Do Amazon Nova 2 Pro and GLM 5.2 support the same reasoning levels?
Amazon Nova 2 Pro exposes low, medium, high, while GLM 5.2 exposes none, minimal, low, medium, high, xhigh, max.
Should I use Amazon Nova 2 Pro or GLM 5.2?
Both are classified in our balanced tier; this editorial grouping does not imply equal capability. Amazon Nova 2 Pro is a candidate for aws-native workloads; GLM 5.2 is a candidate for open-weight deployments. Compare accuracy, tool reliability, latency and cost on representative tasks.
Can I self-host Amazon Nova 2 Pro or GLM 5.2?
GLM 5.2 publishes open weights, but self-hosting and third-party provider access depend on the licence, hardware, serving support, and availability. Amazon Nova 2 Pro is a closed model whose supported access paths are controlled by its provider.

Choosing between them

The verified figures that separate this pair, computed from the catalog rather than restated boilerplate.

  • Input price: Amazon Nova 2 Pro costs $1.25 per 1M tokens versus $1.40 for GLM 5.2 — a 1.1x difference at the headline tier.
  • Deployment: GLM 5.2 publishes weights you can self-host; the other is API-only.
