As of August 25, 2026, Grok-3 Mini is 85% cheaper on blended LLM API pricing. Grok-3 Mini costs $0.30 per million input tokens and $0.50 per million output tokens ($0.80 blended 1M-in + 1M-out). GLM-5V-Turbo costs $1.20 / $4.00 per million tokens ($5.20 blended). Sources: https://docs.z.ai/guides/overview/pricing and https://docs.x.ai/docs/models. The cheapest LLM for your app still depends on how many output tokens you generate.
GLM-5V-Turbo Z AI API pricing is $1.20 input and $4.00 output per million tokens via Z AI. Grok-3 Mini xAI API pricing is $0.30 input and $0.50 output per million tokens via xAI. Use those four numbers, not ChatGPT Plus or Claude Pro subscription prices, when you are comparing APIs.
Grok-3 Mini has a published LiveCodeBench score of 80.4%. GLM-5V-Turbo does not have that eval on this page yet.
GLM-5V-Turbo supports a 203K token context window, while Grok-3 Mini supports 128K tokens. GLM-5V-Turbo offers a larger context window. Filling a larger window bills more input tokens, so the cheaper-per-million model can still cost more on long documents.
Shared benchmark scores for GLM-5V-Turbo and Grok-3 Mini are still limited. Check the comparison table for the evals each model has published. Check the comparison table for GPQA Diamond, SWE-bench, MMLU, HLE, and the other evals we track. Token price and benchmark score together are the usual LLM comparison, not either number alone.
Both GLM-5V-Turbo and Grok-3 Mini are production API models. For cost-sensitive production traffic, Grok-3 Mini has better economics on the blended 1M-in + 1M-out scale. For maximum capability, weight the benchmark table for your domain. Many production stacks route cheap models for drafts and a frontier model for the hard turn, which is usually cheaper than sending everything to the expensive API.
Yes. Call GLM-5V-Turbo through Z AI and Grok-3 Mini through xAI with separate API keys, or through a gateway that already wraps both. Keep prompts in tokens, not characters, when you estimate the invoice. AnotherWrapper templates can swap providers without rewriting auth and billing.
List rates are the latest published Z AI API pricing and xAI API pricing, quoted per million tokens. Official rate sheets: https://docs.z.ai/guides/overview/pricing and https://docs.x.ai/docs/models. Prompt caching, batch APIs, and committed-use discounts can change the invoice. Benchmark scores are from official publications and independent evals, updated as new numbers land.
GLM-5V-Turbo supports up to 128K output tokens per request, while Grok-3 Mini supports up to 8K output tokens. Output tokens are usually the expensive half of API pricing, so a higher max output cap is a capability, not a discount.
Grok-3 Mini has a measured throughput of approximately 100 tokens/second. Throughput data for GLM-5V-Turbo is not yet available. Throughput (tokens per second) and time-to-first-token are why two models with the same per-million-token price can still feel different in chat and agents.
