What you need to know about DeepSeek V4 Pro 0423

DeepSeek, based in China, put DeepSeek V4 Pro 0423 online on April 24, 2026. It accepts text as input and produces text. Its context window reaches 1,048,576 tokens, larger than 93 % of the models in the registry, and it can write up to 384,000 tokens in one go.

It has been available for about 6 months, long enough for its prices and scores to have settled.

DeepSeek V4 Pro 0423 pricing

On OpenRouter, DeepSeek V4 Pro 0423 costs $0.21 per million input tokens and $0.42 per million output tokens. Counting three tokens read for every token written, its average price is $0.261 per million, more expensive than 24 % of paid models (2.9 times cheaper than the median of $0.76).

A concrete example: a task that sends 2,000 tokens (about 1,500 words) and receives a 500-token answer costs $0.0006. At 1,000 tasks a day, budget $19 a month. The price calculator redoes this with your own volumes.

Tokens already sent and cached are billed at $0.017 per million.

Each dot is a model rated by Epoch AI; DeepSeek V4 Pro 0423 is in orange. Higher = more capable, further left = cheaper. Open the LLM benchmark to filter.

For at least equal performance, DeepSeek V4 Flash 0731 and DeepSeek V4 Flash 0423 cost at least 30% less.

Features, privacy and local use

  • It supports tool calling, so it can drive an AI agent, call APIs or MCP servers.
  • It can answer in an enforced JSON format (structured outputs).
  • It is a reasoning model: it "thinks" before answering, which helps on hard tasks but uses more output tokens.

Its weights are open and downloadable from Hugging Face (mit licence): you can run it on your own machines without sending your data to a third party. With 1,598,839,674,782 billion parameters, it needs about 893,421,289,389 GB of memory at 4-bit quantisation. Check with the VRAM calculator. It was downloaded 361,083 times on Hugging Face last month.

Verdict

Computed score: 82/100, from public data (performance, price, context, features).

Strengths

  • Low price: cheaper than 76 % of paid models.
  • Very large context (1M tokens): long documents or a whole codebase fit in one request.
  • Open weights: self-hostable, your data stays with you.
  • Agent-ready: tool calling and structured JSON output.

Limitations

  • Text only: reads neither images nor files.

Avoid if…

  • you want to host it on a single consumer computer (≈ 893,421,289,389 GB needed at 4-bit).
