DeepSeek Text Generation Model

# DeepSeek V4 Pro

DeepSeek's flagship open-weight reasoning model: a large sparse Mixture-of-Experts with a 1M-token context window. At high reasoning effort it ranks among the strongest open models on math and coding, at pricing far below closed frontier peers.

import OpenAI from "openai";

const openai = new OpenAI({
  baseURL: "https://api.inference.net/v1",
  apiKey: "<YOUR_API_KEY>",
});

const completion = await openai.chat.completions.create({
  model: "deepseek-v4-pro",
  messages: [
    {
      role: "user",
      content: "What is the meaning of life?"

for await (const chunk of completion) {
  process.stdout.write(chunk.choices[0]?.delta.content as string);
}
```

Prompt caching

1. Keep the prompt prefix stable and byte-identical across calls.
2. Do not send prompt_cache_key. These routes do not support it and may reject the request.
3. Check usage.prompt_tokens_details.cached_tokens in the response to confirm cache reads.
