Fireworks GLM 5.1 (Global)

GLM-5.1 is Z.ai's next-generation flagship model built for agentic engineering, with stronger coding capabilities and sustained performance over long-horizon tasks with hundreds of iteration rounds. It's a 754B-parameter MoE model

Provider: All Zhipu AI models | Fireworks AI

API Endpoint

https://api.fireworks.ai/inference/v1/chat/completions

Quick Start (Python)

Install: pip install openai

from openai import OpenAI

client = OpenAI(
    api_key="your-fireworks-api-key",
    base_url="https://api.fireworks.ai/inference/v1",
)

response = client.chat.completions.create(
    model="accounts/fireworks/models/glm-5p1",
    messages=[
        {"role": "user", "content": "Hello, how are you?"},
    ],
    max_tokens=1024,
    temperature=0.7,
)

print(response.choices[0].message.content)

Additional examples: Basic invoke, Streaming

Supported Parameters

Parameter	Type	Description
