Quanteta says its LLM API Price Index now tracks list prices, context sizes and maker-published capability scores for 314 large language models across 50 providers, with methodology notes describing how the dataset is assembled and checked.
Quanteta updated its LLM API Price Index on June 4, expanding a public reference for comparing large language model API pricing and model attributes across providers.
Quanteta’s LLM API Price Index says it currently covers 314 models from 50 providers. The index lists per-token API prices, context sizes and maker-published benchmark or capability scores for supported models, according to Quanteta’s index page.
For teams evaluating model deployments, the practical value of the index is not that it picks a single “best” model, but that it places several commercial variables in one table. Quanteta presents prices alongside context-window information and capability-related fields, making it easier to compare models that may differ substantially in both cost structure and technical limits.
The index is especially relevant because LLM API pricing is often expressed in different units and formats across providers. A model can be inexpensive for input tokens but more costly for output tokens, while another may offer a larger context window at a different price point. Quanteta’s data gives readers a way to inspect these trade-offs in one place, while still requiring users to verify final pricing against each provider’s official documentation before making purchasing decisions.
Quanteta Data Lab’s methodology page describes the dataset as being assembled from provider-published pricing pages, model documentation and API sources. The methodology page also says Quanteta computes a blended-price measure, cross-checks entries, and currently covers 314 models across 50 providers.
Quanteta’s methodology states that its blended-price formula is intended to support comparison across different input and output pricing schemes. That kind of normalization can be useful, but it is still a derived metric rather than a provider’s official billing rule. Readers should treat it as an analytical comparison point and consult provider terms for exact costs, discounts, caching rules, batch pricing or regional availability.
The methodology page also notes the use of API-based sources for model metadata. OpenRouter’s public documentation, for example, describes a GET /api/v1/models endpoint that returns available model records and properties such as model IDs, names and context length. Quanteta cites model APIs as one category of source, and OpenRouter’s documentation shows how such structured model metadata can be obtained from an aggregator.
The LLM market changes quickly as providers release new models, rename older versions, alter context lengths or introduce new pricing tiers. A public index that timestamps coverage and explains its methodology can help developers, buyers and analysts compare options more systematically than by reading isolated pricing pages.
However, Quanteta’s own framing also implies limits. The index includes maker-published benchmark or capability scores, which means the figures may come from providers rather than independent evaluations. Benchmark numbers can vary depending on prompt formats, test conditions and model versions. As a result, the index is best read as a structured reference for pricing and published specifications, not as a definitive ranking of real-world model quality.
For organizations choosing an API provider, the most reliable use of the index is as a starting point: shortlist models by price, context window and published capabilities, then validate performance, latency, reliability and final billing terms through direct testing and official provider documentation.
