## How do I call DeepSeek V4.1 Flash?

With the OpenAI SDK, as for any OpenAI-compatible API: set the base URL to `https://llmwithcrypto.com/api/v1`, read your key from `LLMWITHCRYPTO_API_KEY`, and pass `deepseek-v4.1-flash` as the model. Pass your API key as a Bearer token in the Authorization header, as the OpenAI SDK does.

*deepseek_v4_1_flash.py*

```python
import os

from openai import OpenAI

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

resp = client.chat.completions.create(
    model="deepseek-v4.1-flash",
    messages=[{"role": "user", "content": "Classify this support ticket as billing, bug or feature request: \"I was charged twice this month.\""}],
)
print(resp.choices[0].message.content)
print(resp.usage)  # prompt_tokens and completion_tokens: what the call costs

```

## What is DeepSeek V4.1 Flash good for?

V4.1 Flash is the cheaper of DeepSeek’s two current API models; DeepSeek’s own API calls it `deepseek-flash`. The 1017 release is MIT-licensed and listed by almost every host we read, which gives one of the most reliable medians in our [price index](https://llmwithcrypto.com/data/open-model-api-price-index-2026/).

It suits work where volume and speed count: classification, extraction, summaries, first drafts, and agents that make many small calls. Switch to [DeepSeek V4 Pro](https://llmwithcrypto.com/models/deepseek-v4-pro/) when a task needs the larger model.

## What licence does DeepSeek V4.1 Flash come with?

MIT, as published by DeepSeek on Hugging Face: serving the model as an API is allowed with the copyright notice kept. Each model keeps its own licence and use policy (for example Meta’s Llama Acceptable Use Policy and the “Built with Llama” notice); using a model through us means accepting them.

## DeepSeek V4.1 Flash questions

### Why is one host missing from the comparison?

DeepInfra listed V4.1 Flash at a promotional “51% off” price on 23 October 2026. Promotions are left out of our median and of this table, so the comparison stays on list prices.

### Does the price change at night?

No. Ours is the same at every hour. DeepSeek’s own API charges $0.15 input and $0.60 output per million tokens off-peak, half its peak price, as listed on 23 October 2026.

### What do you keep from my requests?

We do not store your prompts or the model’s answers: once a response is sent, its text is gone. Each call leaves one log line with the time, the account, the model and the token counts, deleted after 30 days.
