An open-weight LLM can cost less to serve when its hardware is used efficiently and enough inference runs across it to spread the cost of keeping that capacity available. Downloadable weights do not make inference free: they shift costs from a provider’s bill to compute, infrastructure, and operations. To compare costs fairly, identify what the per-token figure counts, which tokens it divides by, and the model and workload being served.
What does “cost per token” include?
Cost per token is a ratio: a defined set of costs divided by a defined number of tokens. The phrase alone does not say which costs are in the numerator, whether tokens are inputs or outputs, or what period the calculation covers.
| Measure | What it counts | What to watch for |
|---|---|---|
| Provider price | The provider’s charge under its billing rules, commonly quoted separately for input and output tokens. | Rates, regions, tiers, credits, and billing rules can change. Hugging Face’s HF-Inference documentation, for example, describes billing after credits as compute time multiplied by the underlying hardware price; it is not necessarily a simple per-token tariff. |
| Usage-based self-hosting cost | Attributable compute consumed to serve requests, divided by tokens served. | It can help compare serving efficiency, but may omit the cost of capacity held ready, idle time, and shared infrastructure. |
| Allocation-based self-hosting cost | The costs assigned to running and keeping capacity available for a model, divided by its tokens. | CNCF’s August 5, 2026 OpenCost article includes reserved GPU memory for weights, active inference compute, and a share of common infrastructure such as a gateway and KV-cache storage. |
| Full operating or ownership cost | Relevant allocated infrastructure plus other costs of operating the service, such as engineering, storage, networking, reliability, and evaluation. | A GPU-only estimate is partial if it leaves these costs out. A published cost-model repository, RightNow-AI, explicitly excludes several such categories. |
A transparent self-hosting calculation could be attributable hourly cost ÷ tokens served during that hour. State the period and cost categories. If input and output tokens have different economics, report them separately or disclose the mix used to calculate a blended rate. CNCF describes support for separate input- and output-cost calculations; do not compare an API’s output-only rate with a self-hosted blended figure as though they measured the same thing.
Why can open-weight serving cost less?
Capacity can serve more requests
Hardware that is already running can serve additional requests without requiring a separate full allocation for each one. When more useful inference runs on that capacity, its fixed costs are spread across more tokens. Traffic consolidation, model sharing, and routing work across deployments can raise utilization; they do not make the underlying capacity cost disappear.

Serving software can improve hardware efficiency
Kernel fusion, quantization, and scheduling can change how much useful throughput a given hardware setup delivers. NVIDIA attributes improvements in its stack to software factors including these techniques. Their effect depends on the model, hardware, serving stack, and service targets, so a result on one configuration is not a general price guarantee.
Batching and request shape affect work per token
Batching can amortize request-level work across more outputs. A 2026 study measuring energy on H100 and H200 systems found that energy per token varied with model, inference phase, batch size, context length, and output length. In tested settings, larger batches and longer outputs could reduce energy per token by spreading fixed energy over more tokens even while total energy per request increased. Energy is only one cost component, so those findings explain why a static efficiency figure can mislead; they do not establish an all-in cost per token.

Model choice and quantization change resource needs
A smaller or quantized model may need fewer resources, but model size alone does not determine efficiency, and a change in precision can affect quality and throughput. A preliminary 2026 study tested 18 open models ranging from 0.5B to 7B parameters on one RTX 4060 Ti 16GB system. In its specified tests, it reported 0.2747 J/token for qwen2.5:0.5b and 0.3234 J/token for tinyllama:1.1b, with throughput above 325 tokens per second for those cases. The authors’ results apply to that system, Ollama setup, and prompt set—not to arbitrary prompts or hardware. They support benchmarking candidates on the workload you need, not a universal rule that the smallest model is cheapest.
When is self-hosting cheaper than an API?
It depends on utilization and what each side of the comparison includes. CNCF’s August 2026 OpenCost article gives an illustration, not a general break-even price: at 25% utilization, it assigns $1 per million tokens to usage cost and $4 per million to allocation cost, compared with $2 per million for an external API. In that example, self-hosting becomes competitive above about 50% utilization. The figures are specific to the article’s assumptions; they are not market-wide rates or a prediction for another deployment.

The gap between the example’s usage and allocation figures shows why “GPU cost per token” can answer a different question from “what does serving this model cost us?” A system may consume relatively little compute per token while still carrying substantial cost for reserved capacity. Conversely, high sustained use may spread that capacity cost over many more tokens.
For your own comparison, line up the same service requirements and accounting boundary on both sides. Include the model and quality target, request mix, context lengths, throughput, latency, availability, and relevant operating costs. Use current provider and hardware pricing for the region and tier you would actually use; the cited studies and examples are not current price quotes for your deployment.

What should you include in a fair comparison?
| Comparison factor | Why it changes the result |
|---|---|
| Model and quality target | Models with different capabilities or sizes are not equivalent units of work. A cheaper token is not a cost saving if it does not meet the task’s quality needs. |
| Input/output mix and context length | Providers may price input and output differently, and request shape changes processing and energy use. |
| Quantization and serving stack | Precision, kernels, scheduling, and inference engine affect throughput and quality. The RightNow-AI cost model warns that quantization is not held constant across its comparisons. |
| Utilization and burstiness | Reserved capacity still contributes to allocation cost when requests are sparse or bursty; sustained use can distribute fixed costs across more tokens. |
| Throughput, latency, and availability targets | A configuration with attractive throughput may not meet interactive latency, uptime, or redundancy requirements. |
| Included cost categories | Compute-only arithmetic can omit staffing, storage, networking, idle capacity, and reliability costs that matter to an actual service. |
| Billing basis, region, and date | Provider rates, credits, rental prices, and hardware prices change. Record the applicable tier, region, billing basis, and date when quoting a live price. |
Which costs are easy to leave out?
A published RightNow-AI cost model flags exclusions that can materially change an estimate. It excludes engineer time, storage, image registry, network egress, cold starts, weight loading, on-call work, redundancy, load balancers, and model evaluation; it also excludes idle capacity beyond its utilization assumption. These are not necessarily costs every deployment will incur in the same way, but a comparison should include relevant ones or label the estimate as excluding them.
Keep the scope consistent: if your self-hosted calculation includes reserved GPU capacity and operations, compare it with a provider price that meets similar service requirements, not merely with a compute-only rate. If a number is intended only to compare token-generation efficiency, label it that way rather than presenting it as the cost of operating a production service.

How to read benchmark claims
Benchmark results are useful when their conditions resemble the deployment being considered. NVIDIA’s 2026 material, citing SemiAnalysis InferenceX benchmarks as of April 2026, reports $0.123 per million tokens at 116 TPS/user interactivity for GB300 NVL72 using NVIDIA Dynamo and TensorRT-LLM. It also reports a change from $0.11 to $0.02 per million tokens for GPT-OSS-120B within two months, attributing that change to software alone. These are vendor-published claims tied to the named platform, stack, model, benchmark, and time context; they are not general cost estimates for other workloads.
More broadly, energy-per-token results are not cost-per-token prices, and throughput results do not include every cost of a reliable service. No single independently measured cost-per-token figure applies universally: the answer changes with configuration, accounting scope, workload, and utilization.
Is “open-source LLM” the right term?
When the specific point is that downloadable model weights can be run on infrastructure you control, “open-weight model” is often more precise. Availability of weights by itself does not establish that every model component or its license qualifies as open source. Check the particular model’s license and terms before deploying it; the ability to download weights is not a substitute for that review.
