Spread = priciest source / cheapest source for the same model, each blended at 3 input tokens per output token with OpenRouter's 5.5% credit fee added. Saving = what you keep by buying at the cheapest source instead of the priciest. Official prices checked 9 November 2026; OpenRouter and Straitly prices fetched 9 November 2026.

How much does cached input save?

Re-reading a cached prompt prefix costs a median 90% less than fresh input on the official APIs. For agents and RAG, cache hit rate moves the bill as much as where you buy.[7-15]

Discount = 1 minus cached-read price divided by input price, within the same source. Cache writes and storage are priced separately by some makers and are not included. Cheapest cached read includes OpenRouter's 5.5% fee. Official prices checked 9 November 2026; OpenRouter and Straitly prices fetched 9 November 2026.

How is the index built?

Three public sources per model, one blend, one fee, lowest wins. Straitly is the lowest on 56 of 60.

  1. 1Three public prices per model

    Official from each maker's pricing page; OpenRouter and Straitly from their public APIs.[1][3][7-15]

  2. 2One 3:1 blend

    (3 x input + 1 x output) / 4 gives one price per 1M tokens.

  3. 3OpenRouter's fee is added

    Its 5.5% credit fee goes on top before the three are compared.[4]

  4. 4The lowest wins

    A tie goes to the official API.[6]

Method: six rules behind every number
  • Official API. The standard pay-as-you-go price on the maker's own pricing page, read by hand on 9 November 2026. Where a maker shows peak and off-peak or short and long prompt prices, the index uses the lower standard price and says so in the price notes. Batch and priority tiers are left out.
  • OpenRouter.The per-token price its public models API lists for the model id, times 1M. OpenRouter says: "Inference is billed at the provider's list price on every plan. OpenRouter's fee is charged when you buy credits, 5.5% on Standard and 8% on Business, never on individual requests." The table shows the listed price; the cheapest column adds 5.5%.[4]
  • Straitly. The price in Straitly's live public catalog, the same data behind straitly.ai/models. Straitly bills prepaid, per token, with no subscription and no minimum (pricing).[1][2]
  • Cheapest. (3 x input + 1 x output) / 4, the lowest wins and a tie goes to the official API. Cached-input prices are listed for reference but not blended. A mostly-input or mostly-output workload can change the winner, so each model page also prices three monthly workloads.
  • Inclusion. A model is listed only when at least two of the three sources publish a price for it.
  • Two denominators. Counts on this page (56 of 60) cover the 60 models in this index and OpenRouter's listed price for each model id. The compare pages use Straitly's full public catalog (164 models on 9 November 2026) against the cheapest OpenRouter seller per model, which is where 129 of 141comes from. Different sets: Straitly's own prices match where they overlap, but each set takes its reference prices from its own source, so a reference price can differ between them.[5]
Models cheaper on another source (4)

In this index, 3 are cheapest on OpenRouter and 1on the maker's own API.[5][6]

What do buyers ask about LLM API prices?

Is Straitly always the cheapest LLM API?

Not always. Straitly is the cheapest of the three sources on all 36 Claude, GPT, Gemini and Grok models and on 56 of the 60 models in this index. It is not the cheapest on DeepSeek V4.1 Flash (OpenRouter is 13% lower), DeepSeek V4 Pro (DeepSeek's API is 17% lower), GLM-5.3 (OpenRouter is 36% lower), GLM-5.3-Flash (OpenRouter is 20% lower). Straitly's full catalog, a wider set, shares 141 models with OpenRouter; there Straitly is below the cheapest OpenRouter seller on 129 of 141 (snapshot 9 November 2026). The 12 where an OpenRouter seller is cheaper are all open-weight models: Qwen, GLM, Gemma, DeepSeek, Kimi and gpt-oss variants.

What is the cheapest Claude API?

Straitly is the cheapest of the three sources on all 15 Claude models in the index at a 3:1 input-to-output mix. The lowest-priced Claude model is Claude Haiku 5.5: $0.06 input and $0.30 output per 1M tokens on Straitly, against $0.10 and $0.50 on Anthropic's API.

What is the cheapest DeepSeek API?

Straitly is the cheapest of the three sources on 1 of 3 DeepSeek models at a 3:1 input-to-output mix. OpenRouter is cheaper for DeepSeek V4.1 Flash and DeepSeek's own API is cheaper for DeepSeek V4 Pro. The lowest-priced DeepSeek model is DeepSeek V4.1 Flash: $0.006 input and $0.50 output per 1M tokens on OpenRouter, against $0.15 and $0.60 on DeepSeek's API.

What is the cheapest Kimi API?

Straitly is the cheapest of the three sources on all 5 Kimi models in the index at a 3:1 input-to-output mix. The lowest-priced Kimi model is Kimi K2.5: $0.27 input and $1.35 output per 1M tokens on Straitly.

What is the cheapest Qwen API?

Straitly is the cheapest of the three sources on all 7 Qwen models in the index at a 3:1 input-to-output mix. The lowest-priced Qwen model is Qwen3.7 Flash: $0.0168 input and $0.066 output per 1M tokens on Straitly, against $0.03 and $0.13 on Alibaba Cloud's API.

3 more questions: method, fees and price gaps
How much does the same model cost from different providers?
Across the 60 models, the priciest source costs a median 1.8x the cheapest one, blended at 3:1 with OpenRouter's 5.5% fee included. The widest gap is Qwen3.5 397B A17B: $0.2322 per 1M blended tokens on Straitly against $1.4243 on OpenRouter, 6.1x apart.
Does OpenRouter charge more than the list price?
OpenRouter's pricing page says: "Inference is billed at the provider's list price on every plan. OpenRouter's fee is charged when you buy credits, 5.5% on Standard and 8% on Business, never on individual requests." So on the Standard plan every dollar of usage costs about $1.055 of card spend. Its listed per-token price for some open-weight models is below the official price, and the index shows those cases.
How is the index built, and can I reuse the data?
Straitly and OpenRouter prices come from their live public APIs; official prices are read by hand on each maker's pricing page. For each model the index blends input and output at 3:1, adds OpenRouter's 5.5% credit fee, and picks the lowest; a tie goes to the official API. This edition is dated 9 November 2026.
