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
Qwen3-4B FP8 needs about 9 GB of GPU memory at 4-bit with its full 32K context. The cheapest rental that fits is 1× RTX 3060 at about $58 a month.

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. No guarantee of runtime support, usable performance, or that a matching quantized build exists. Pricing methodology.

Common questions
What is Qwen3-4B FP8 good for?
Edge and on-device deployment, local chat and small tool-calling loops. Apache 2.0 weights at the light end of the Qwen3 lineup, small enough for a single consumer GPU.
When is Qwen3-4B FP8 not a good fit?
Image, video or audio input: it is text only. Heavier reasoning and long-document work, which the larger dense and MoE models in the same lineup are sized for.
What is the cheapest way to run Qwen3-4B FP8?
No provider we track hosts it; self-hosting on the cheapest rental that fits (1x RTX 3060, $0.08 per hour) costs about $58 a month.
Can I self-host Qwen3-4B FP8?
Yes. The weights are Apache 2.0 licensed. At 4-bit it needs about 9 GB of GPU memory, which starts at roughly $58 a month on the cheapest rental that fits.
