deepseek

DeepSeek on RunAPI

Use OpenAI-compatible endpoints at https://runapi.ai/v1 as the primary protocol.

Primary protocol recipe

Authenticate

Set OPENAI_API_KEY to a RunAPI API key and OPENAI_BASE_URL to https://runapi.ai/v1.

Send request

from openai import OpenAI
client = OpenAI(api_key="YOUR_RUNAPI_TOKEN", base_url="https://runapi.ai/v1")
response = client.chat.completions.create(
    model="deepseek-v4-pro",
    messages=[{"role": "user", "content": "Explain this decision."}],
)
print(response.choices[0].message.content)
print(response.usage)

For long output, set stream=True and stream_options={"include_usage": True}; consume through [DONE]. deepseek-v4-flash additionally supports one custom function on Responses; keep automatic tool selection and one serial call/result lifecycle.

Verify result

For Chat, require final assistant content, finish_reason, and usage. For Responses, require final output, one usage-bearing response.completed, and [DONE] when streaming.

Stop boundaries

Correct a rejected shape once using the structured error. Retry transport once only before any response or Usage and when replay is safe. Record a terminal error and stop without changing model or protocol. Add tools, reasoning, storage, cache controls, documents, or multimodal input only when the current RunAPI contract verifies the exact model/protocol shape.

Compatibility protocols

Load compatibility protocols only when an existing client requires Anthropic Messages or Gemini contents.
