How we price

Order

Providers are listed cheapest input rate first, then by output rate, a tie going to the creator's own listing. A provider that lists the model without a published rate sits at the end.

Prices

Base-tier, on-demand rates in USD per 1M tokens, converted at ECB reference rates where a provider publishes in another currency. Cached-input and batch rates show only where a provider publishes them. "Cheapest" marks the one provider with the lowest input and output pair; a tie wears no badge.

Cost

Input rate times the input tokens plus output rate times the output tokens, at the monthly volume set above the table. Cached-input, batch, long-context and reasoning-token billing are not modelled.

Heads up: Base-tier, on-demand rates per 1M tokens; cached, batch and long-context tiers excluded. A provider may serve a shorter context or a quantized build than the creator's release. Verify before provisioning. More on how we price.

Estimated cost to self-host

DeepSeek V4.1 Flash needs about 306 GB of GPU memory at 4-bit with 32K context. The cheapest rental that fits is 8× RTX A6000 at about $3,283 a month.

That costs the same as roughly 7B tokens a month on DeepSeek's API. Self-hosting is more expensive below that volume.

What it costs to self-host DeepSeek V4.1 Flash at each precision: the memory it needs, the cheapest rental that holds it, that rental's month and the API volume it pays off at

Estimates based on median on-demand rates for Nvidia GPUs. Memory is weights plus KV cache for one request, using FP8 KV cache where supported and FP16/BF16 otherwise. Break-even assumes a 5:1 input-to-output ratio. No guarantee of runtime support, usable performance, or that a matching quantized build exists. Pricing methodology.

Common questions

What is DeepSeek V4.1 Flash good for?

Long-context agent and coding work, and tasks that mix images with text. MIT-licensed weights, far lighter to self-host than V4 Pro, though the 552B backbone still takes a multi-GPU node.

When is DeepSeek V4.1 Flash not a good fit?

Audio and video work: it takes text and images in, and returns text only. Self-hosting still takes a multi-GPU node, and DeepSeek's own API charges the list rate at peak hours, so the price depends on the time of day.

What is the cheapest way to run DeepSeek V4.1 Flash?

Hosted, unless you push serious volume. DeepSeek charges $0.30 in / $1.20 out per 1M tokens. The cheapest rental that fits is 8x RTX A6000 at $3,283 a month, which costs the same as about 7B tokens a month on that API.

How does DeepSeek V4.1 Flash compare with DeepSeek V4 Flash?

DeepSeek says V4.1 Flash moves the Flash line onto a Causal Encoder-Decoder architecture that activates fewer parameters on input than on output, adds native image understanding, and compresses the KV cache, which it says cuts the cache-hit charges that dominate agent costs. Same 1M-token context. DeepSeek V4.1 Flash costs 275% more per 1M input tokens and 376% more per 1M output tokens than DeepSeek V4 Flash, at each model's cheapest listed provider. It came out 5 months later, has more parameters (552B with 16B active against 284B with 13B active) and takes image input, which DeepSeek V4 Flash does not.

Can I self-host DeepSeek V4.1 Flash?

Yes. The weights are MIT licensed. At 4-bit it needs about 306 GB of GPU memory, which starts at roughly $3,283 a month on the cheapest rental that fits.
