Kimi K2.5 and GLM-5 are both top-tier models that compete with US giants. We compare them using Artificial Analysis benchmarks so you can see how they stack up.
Kimi K2.5 vs GLM-5: Strong Alternatives to US Frontier Models
You don’t have to stick to US providers for top-tier language models. Kimi K2.5 (Moonshot/Kimi) and GLM-5 (Z AI / GLM) both rank near the front of the pack on Artificial Analysis’s independent benchmarks. Here’s a straightforward comparison so you can see how they stack up—and when each might be the better fit.
The Numbers
On the Artificial Analysis Intelligence Index v4.0:
- GLM-5 (reasoning) scores 49.64—right up there with GPT-5.2 and Claude Opus 4.5. It’s a genuine frontier model with strong results on agentic tool use (τ²-Bench Telecom) and other evals.
- Kimi K2.5 (reasoning) scores 46.73; the non-reasoning variant is at 37.18. So for hard tasks, the reasoning version is the one to use. Kimi also does well on tool use and long-context style benchmarks.
So on this aggregate index, GLM-5 has a few points on Kimi K2.5; both are clearly in the “frontier” tier and well ahead of mid-tier models.
Where Each Shines
GLM-5 often leads on agentic and tool-use benchmarks in the data we’ve seen. If you’re building agents, automations, or apps that rely on function-calling and tools, GLM-5 is a strong candidate and can be more cost-effective than some US options. Check Artificial Analysis for the latest speed and price.
Kimi K2.5 is known for long context and solid reasoning. If your use case is long documents, RAG, or multi-turn reasoning with big context windows, Kimi is worth testing. It’s also open weights in some form, which can mean more deployment flexibility and provider choice.
Speed and Cost
Both models are available via API; Artificial Analysis tracks output speed and cost per 1M tokens. In general, non-US providers can offer competitive pricing—so if you’re optimizing for cost or diversity of supply, Kimi and GLM-5 are both worth including in your evaluation.
When to Choose Which
- Lean toward GLM-5 if you want maximum capability in this tier and care a lot about agentic and tool-use performance.
- Lean toward Kimi K2.5 if long context and reasoning are your priorities, or if you prefer a model with open-weight options and multiple providers.
