Z.AI: GLM 5.3
GLM-5.3 is the next-generation model in Z.AI's GLM series, supporting up to 1M context tokens and 128K output tokens. Native deep thinking, tool calling and structured output support long-document understanding, code generation and complex reasoning. Served on our own compute infrastructure, with both OpenAI and Anthropic API protocols.
Supply channels
Multiple compute channels with automatic failover when a channel is rate limited or unavailable.
Channels are ordered by request volume over the last 24 hours. A valid public provider name is shown when available; otherwise a generic channel label is used. Availability, latency and throughput use a rolling 24-hour window. Hourly colors show operational, degraded, down or no-traffic periods. Hover for actual values. The price is the same across channels.
Quick start
OpenAI / Anthropic compatible: change the base URL and set the model to z-ai/glm-5.3.
from openai import OpenAI
client = OpenAI(
base_url="https://api.goodputai.cn/v1",
api_key="GOODPUT_API_KEY",
)
resp = client.chat.completions.create(
model="z-ai/glm-5.3",
messages=[{"role": "user", "content": "Hello"}],
)
print(resp.choices[0].message.content)Billing method：Billed by token usage: Input CN¥4.00 · output CN¥14.00, per million tokens.Web search is billed separately: CN¥0.00 per search.

GLM-5.2 supports a larger context window and output length, with up to 1M context and 128K output tokens. It adds streaming output for tool calls via `tool_stream=true`, enabling real-time access to tool call arguments. Like the GLM-4.7 series, it supports deep thinking with `thinking={ type: "enabled" }`, where thinking is enforced once enabled, and introduces `reasoning_effort` to control reasoning intensity under chain-of-thought mode. It also delivers stronger coding performance and more advanced reason
MiniMax H3 video generation supports text-to-video, image-to-video (first frame or first/last frames), and reference-to-video using text, images, audio and video. Output: 768P, with audio generated by default. Billed by successfully generated duration at a list price of CNY 0.50/second; promotional pricing is shown on the page. Failed generations are not billed. Reference images, audio and video inputs are temporarily free.
MiniMax H3: text/image/reference-to-video (first or first/last frames), with text/image/audio/video inputs. 768P; audio on by default. List CNY 0.50/s; promo price on page. Failures unbilled; reference inputs temporarily free. Fast: pull-mode queue; submit returns task id. Only 1344x768 (16:9, default) or 768x1344 (9:16); 5–14s (default 5s). Frame rounding may add up to ~0.7s; billed by requested seconds. Other parameters match H3.
