The MiniMax M-series text models are available through Upmore via the standard Chat Completions API (/v1/chat/completions). All models in the series share the same request and response format — switch between them by changing the model parameter.

Available models

ModelNotes
MiniMax-M3Latest generation
MiniMax-M2.7
MiniMax-M2.7-highspeedHigh-speed variant of M2.7
MiniMax-M2.5
MiniMax-M2.5-highspeedHigh-speed variant of M2.5
MiniMax-M2.1
MiniMax-M2.1-highspeedHigh-speed variant of M2.1
MiniMax-M2
The -highspeed variants accept the same parameters and return the same response format as their standard counterparts. They run on faster inference infrastructure and are billed at a higher rate — pick them when latency matters more than cost.

​
Key capabilities

  • Chat Completions API — Standard /v1/chat/completions endpoint with messages
  • Streaming — Supports real-time token streaming via SSE
  • Tool use — Supports function calling and tool use

Quick example

curl https://api.upmore.net/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "MiniMax-M3",
    "messages": [
      { "role": "user", "content": "Explain quantum entanglement in simple terms." }
    ]
  }'

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://api.upmore.net/v1"
)

response = client.chat.completions.create(
    model="MiniMax-M3",
    messages=[
        {"role": "user", "content": "Explain quantum entanglement in simple terms."}
    ]
)

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

from openai import OpenAI

    messages=[

    ],
    stream=True
)

for chunk in stream:
    if chunk.choices and chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="")
