DeepSeek — frontier quality at a fraction of the price

DeepSeek models in GPTunneL: 1M token context, a reasoning mode and open weights. Pay per token, no subscription and no VPN.

What the DeepSeek family is good at

Traits DeepSeek keeps from one generation to the next — you can count on them whichever model you pick.

Below-market pricing

The main reason people pick the family: at comparable quality DeepSeek costs several times less than Western models of the same tier.

Reasoning mode

The model can think a task through and show its working — the thing people used to reach for a separate R1 model to get.

Strong at code

Developers like this family: it edits code carefully, reads large files and explains other people's decisions.

Open weights

The models are published under a free licence and can be run on your own hardware. In GPTunneL you can try them without owning any.

Which model to pick

Three current models — the fresh V4.1 Flash and two fourth-generation models. They differ in capabilities and price.

September 2026

DeepSeek V4.1 Flash

Flash opened the update to the fourth generation. According to DeepSeek, it beats the previous flagship V4 Pro on both quality and speed — especially in code and long multi-step tasks — while costing less. Context stays at a million tokens, and image understanding was added on top. There is no Pro version yet.

April 2026

DeepSeek V4 ProDeepSeek V4 FlashDeepSeek V4 Flash Vision

Two models at once: Pro for hard tasks and the lighter Flash. Context grew to a million tokens and the reasoning mode moved into the model itself. Later an experimental Flash Vision branch joined them — the same Flash, but able to read images.

DeepSeek V3

The first generation that got the company noticed outside China.

How billing works

There is no subscription: you top up one balance and spend it on any model on the platform.

Pay per token

You are charged for exactly what the request and the answer used. Not using it costs nothing: no limits, no monthly fee.

One balance for every model

DeepSeek, ChatGPT, Claude, image and video generation — all out of the same wallet. No separate subscription per service.

Top up the way you prefer

International cards, Apple Pay, Google Pay or crypto. The minimum top-up is $5.

Function review

The bug is on line 14: the counter is reset inside the loop, so the total always equals the last step.

Move the initialisation out of the loop and the accumulation will run across every element.

While you are there, replace the == comparison with is when checking for None.

Sign in whichever way suits you.

The model switches right inside the input — you can change it mid-conversation.

The answer lands in the chat and the context is kept until the conversation ends.

Signing up takes a minute, and $5 on the balance is enough to see whether the model fits your task.

Frequently asked questions

No. Requests go through GPTunneL's infrastructure, so the models open like any ordinary website — no VPN and no proxy.

DeepSeek is a family of neural networks from the Chinese company DeepSeek — the one that made the market recalculate the cost of artificial intelligence in early 2025, when its models matched Western flagships at a fraction of the price.

The family answers questions and writes and edits text, but it is best known for code and reasoning: the model can think a hard task through and reach the answer via intermediate steps. The current models hold up to a million tokens in context — a folder of documents or an entire project at once. The weights are published under a free licence, so DeepSeek can also be run on your own hardware.

DeepSeek models are available in GPTunneL — worldwide, without a VPN, with one balance and billing for the tokens you actually spend.
