Deep dive
On shared benchmark coverage, SWE-bench Verified has GLM-5 at 77.8 and Kimi K2.6 at 80.2, with Kimi K2.6 ahead by 2.4 points; SWE-bench Pro has GLM-5 at 38.6 and Kimi K2.6 at 58.6, with Kimi K2.6 ahead by 20 points. The largest visible gap is 20 points on SWE-bench Pro, which matters most when that benchmark mirrors your workload. Treat isolated benchmark wins as directional, because provider routing, prompt style, and tool access can move real application results.
The capability footprint differs most on vision: Kimi K2.6, multimodal input: Kimi K2.6, and structured outputs: GLM-5. Both models share reasoning mode, function calling, and tool use, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
For cost, GLM-5 lists $0.6/1M input and $2.08/1M output tokens, while Kimi K2.6 lists $0.75/1M input and $3.5/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts GLM-5 lower by about $0.53 per million blended tokens. Availability is 5 providers versus 5, so concentration risk also matters.
Choose GLM-5 when provider fit and lower input-token cost are central to the workload. Choose Kimi K2.6 when coding workflow support and larger context windows are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
FAQ
Which has a larger context window, GLM-5 or Kimi K2.6?
Kimi K2.6 supports 262K tokens, while GLM-5 supports 200k tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible. Use this as a quick comparison signal, then confirm the provider-specific limits before committing to production.
Which is cheaper, GLM-5 or Kimi K2.6?
GLM-5 is cheaper on tracked token pricing. GLM-5 costs $0.6/1M input and $2.08/1M output tokens. Kimi K2.6 costs $0.75/1M input and $3.5/1M output tokens. Provider discounts or batch pricing can still change the final bill.
Is GLM-5 or Kimi K2.6 open source?
GLM-5 is listed under MIT. Kimi K2.6 is listed under Open Source. License labels affect whether you can self-host, redistribute weights, or rely only on hosted APIs, so confirm the upstream license before deployment.
Which is better for vision, GLM-5 or Kimi K2.6?
Kimi K2.6 has the clearer documented vision signal in this comparison. If vision is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ. Use this as a quick comparison signal, then confirm the provider-specific limits before committing to production.
Which is better for multimodal input, GLM-5 or Kimi K2.6?
Kimi K2.6 has the clearer documented multimodal input signal in this comparison. If multimodal input is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
Where can I run GLM-5 and Kimi K2.6?
GLM-5 is available on Fireworks AI, OpenRouter, Together AI, GCP Vertex AI, and NVIDIA NIM. Kimi K2.6 is available on NVIDIA NIM, Moonshot AI Kimi, Fireworks AI, OpenRouter, and Microsoft Foundry. Provider coverage can affect latency, region availability, compliance posture, and fallback options.
