DeepSeek V4 Pro - Starrise AI

DeepSeek V4 Pro is available through Starrise AI via the OpenAI-compatible interface. Supports thinking mode, function calling, and JSON mode.

Key Capabilities

OpenAI-compatible — Drop-in replacement for the OpenAI SDK, no other code changes needed
Thinking mode — Deep thinking with configurable reasoning intensity
Function calling — Native support for tools and function calls
JSON mode — Structured output via response_format
Long context — Supports large document processing and multi-turn conversations
Streaming — Real-time token streaming via SSE
Prompt caching — Automatic caching with hit/miss statistics returned

Quick Example

curl https://ai.alad.com/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "deepseek-v4-pro",
    "messages": [
      { "role": "user", "content": "Explain quantum entanglement in simple terms." }
    ]
  }'

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://ai.alad.com/v1"
)

response = client.chat.completions.create(
    model="deepseek-v4-pro",
    messages=[
        {"role": "user", "content": "Explain quantum entanglement in simple terms."}
    ]
)

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

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://ai.alad.com/v1"
)

stream = client.chat.completions.create(
    model="deepseek-v4-pro",
    messages=[
        {"role": "user", "content": "Write a short poem about the ocean."}
    ],
    stream=True
)

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

`stop`	string / array	No	Sequences where generation stops (up to 16)
`response_format`	object	No	`{"type": "json_object"}` to enable JSON mode
`tools`	array	No	List of function calling tools
`tool_choice`	string / object	No	Tool selection control: `none`, `auto`, `required`, or specify a function
