DeepSeek V4 Flash

Fast free next-gen model

What it's the best tool for

Completely free with no request limits
Lightning-fast inference thanks to efficient Mixture-of-Experts design
One million token context for analyzing large codebases
Excellent performance on coding and reasoning tasks
Native Russian language support

Limitations

When to reach for something else

No built-in web search — relies only on context from your prompt
Text-only model, no image or video generation
Budget version — less capable than Pro on complex multi-step reasoning

Sample output

How DeepSeek V4 Flash responds

Prompt

Refactor this Python code to async version with asyncio and error handling, add logging.

DeepSeek V4 Flash

Here's the async version: import asyncio import logging logging.basicConfig(level=logging.INFO) logger = logging.getLogger(__name__) async def fetch_data(url): try: # async request implementation logger.info(f"Fetching {url}") return data except Exception as e: logger.error(f"Failed to fetch {url}: {e}") raise Ready for production with exception handling at each level.
