04 — Questions

Which should you choose?

Which is better: GLM-5.1, GLM-5.2 or Kimi K2.7 Code?

It is close. Our weighted score puts them within 3 points (Kimi K2.7 Code 64/100, GLM-5.2 61/100, GLM-5.1 57/100), so choose by what matters most for your work: GLM-5.2 for raw capability and Kimi K2.7 Code on price. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%.

Which is cheaper, GLM-5.1, GLM-5.2 or Kimi K2.7 Code?

Kimi K2.7 Code is cheaper at $0.95 input / $4.00 output per million tokens (official Moonshot AI API price). GLM-5.1 costs $1.40 input / $4.40 output per million tokens (official Z.AI API price); GLM-5.2 costs $1.40 input / $4.40 output per million tokens (official Z.AI API price). At a typical mix of three input tokens to one output token, that is $1.71 per million tokens for Kimi K2.7 Code versus $2.15 for GLM-5.1 (1.3× as much) and $2.15 for GLM-5.2 (1.3× as much).

Which scores higher on benchmarks?

GLM-5.2 scores higher on the Capabilities Index (ECI): GLM-5.2 151.8 (#44 of 148), Kimi K2.7 Code 150.0 (#49 of 148) and GLM-5.1 149.9 (#51 of 148). The confidence ranges of the top two overlap (149.8–154.0 vs 148.1–151.8), so treat the gap as small. On individual benchmarks: GPQA Diamond — GLM-5.2 91.9%, GLM-5.1 89.9%, Kimi K2.7 Code 87.9%; FrontierMath Tiers 1–3 — GLM-5.2 59.2%, Kimi K2.7 Code 54.0%, GLM-5.1 36.8%; OTIS Mock AIME 2024–2025 — Kimi K2.7 Code 95.6%, GLM-5.1 93.3%, GLM-5.2 86.4%; SimpleQA Verified — Kimi K2.7 Code 36.5%, GLM-5.2 34.2%, GLM-5.1 34.0%.

Which is better for coding?

There are no published SWE-bench Verified results for Kimi K2.7 Code yet, so there is no like-for-like coding score. On overall capability, GLM-5.2 leads, which tends to carry over to coding, but test on your own codebase. All three support tool calling for agent workflows.

Which has the bigger context window?

GLM-5.2 has the largest context window at 1,000,000 tokens, against 262,144 for Kimi K2.7 Code and 200,000 for GLM-5.1. Maximum output per response: GLM-5.1 up to 131,072, GLM-5.2 up to 131,072, Kimi K2.7 Code up to 262,144 tokens.

Which can read images, PDFs, audio or video?

GLM-5.1 accepts text; GLM-5.2 accepts text; Kimi K2.7 Code accepts text, images and video. Kimi K2.7 Code handles the widest range of inputs.

Are any of these open source?

Yes, all three publish their weights, so you can self-host them.

Which is newer?

GLM-5.2 is the newest, released Jun 13, 2026. Kimi K2.7 Code came out Jun 12, 2026; GLM-5.1 came out Apr 7, 2026. Knowledge cutoff: Kimi K2.7 Code Jan 2025.

How do you decide the winner?

Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Oct 4, 2026.
