GLM-5.2 is Z.ai’s flagship model for the era of long-horizon tasks. With a truly usable 1M-token context window, it can handle project-level engineering context, execute long-running tasks more reliably, follow engineering standards more consistently, and complete the full development workflow from requirements to multi-platform deployment in a single task.
GLM 5.2 vs GPT 5.6 Sol Disc
Output tokens cost $1.97 per million on GLM 5.2 and $15.00 per million on GPT 5.6 Sol Disc. Input tokens cost $0.56 per million on GLM 5.2 and $2.50 per million on GPT 5.6 Sol Disc. Cached input tokens are billed at $0.14 per million on GLM 5.2 and $2.50 per million on GPT 5.6 Sol Disc. Discounted rates are shown where a promotion is active. Context lengths are 1,000,000 tokens on GLM 5.2 and 1,050,000 tokens on GPT 5.6 Sol Disc. Time to first token (TTFT) measured on AIHubMix is 0.8s on GLM 5.2 and 2.0s on GPT 5.6 Sol Disc. Measured output throughput is 42.5 tok/s on GLM 5.2 and 30.2 tok/s on GPT 5.6 Sol Disc.
GPT-5.6 Sol (limited-time 50% off) is OpenAI’s frontier reasoning model for complex coding, professional knowledge work, deep research, and long-running agents. It supports a roughly 1.05M-token context window, image understanding, and extensive tool use. Compared with Terra and Luna, Sol prioritizes capability and reliability on demanding tasks.

Which responds faster?
GLM 5.2: 0.8s time to first token measured on AIHubMix; see the live performance charts above for how each model behaves across the day.
How large is each context window?
GLM 5.2 accepts 1,000,000 and GPT 5.6 Sol Disc accepts 1,050,000 input tokens. Maximum output per request is 128,000 tokens on GLM 5.2 and 128,000 tokens on GPT 5.6 Sol Disc.
Which one generates tokens faster?
GLM 5.2 at 42.5 tok/s and GPT 5.6 Sol Disc at 30.2 tok/s, measured as output throughput on AIHubMix — a separate metric from time to first token.
What inputs and capabilities does each model support?
GLM 5.2 accepts text input and supports thinking, tool calling, function calling and structured outputs; GPT 5.6 Sol Disc accepts text and image input and supports tool calling, thinking and structured outputs.
Can I call GLM 5.2 and GPT 5.6 Sol Disc with the same API key?
Yes. AIHubMix serves every model on this page behind one OpenAI-compatible endpoint, so switching between them is a one-line change to the model field — no second account, key or SDK.
