MIGRATION & COMPATIBILITY

Migration guide

Migrating from Text Completions

DEVUP AI does not expose the legacy /v1/completions endpoint. For OpenAI-compatible text generation, use Chat Completions.

Availability notice

  • /v1/completions is not in the current API contract.
  • Requests should use /v1/chat/completions.
  • The selected model must support chat-style input.

Text Completions vs Chat Completions

Legacy Text Completions

  • Raw prompt string
  • Model-specific prompt formatting
  • Endpoint not currently exposed by DEVUP AI

Chat Completions

  • Structured messages array
  • Explicit roles such as system, user, and assistant
  • Current OpenAI-compatible interface for text generation

Legacy raw prompt

Illustrative only

A conceptual legacy input (illustrative only, not a runnable DEVUP AI API request):

text
Summarize the following text:

<document>

DEVUP AI Chat Completions

The equivalent Chat Completions request formatted as a structured messages array:

import os
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["DEVUP_API_KEY"],
    base_url="https://api.devupai.com/v1",
)

response = client.chat.completions.create(
    model="deepseek-ai/DeepSeek-V4-Pro",
    messages=[
        {
            "role": "user",
            "content": "Summarize the following text:\n\n<document>",
        }
    ],
)

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

Migration checklist

  • Replace /v1/completions with /v1/chat/completions
  • Replace prompt with messages
  • Assign the correct message roles
  • Keep the DEVUP AI base URL and API key
  • Confirm that the selected model supports Chat Completions
  • Re-test stop conditions and output-length controls
