How this price is scoped: Unbiased makes Pareto and is its only seller, so this is a first-party list price. Its own rate card at https://unbiased.ai/pricing/ (read 2026-09-18, receipt data/evidence/unbiased-pareto/2026-09-18.txt) prints the three legs as money rather than as a ratio — "Input $2.50 / Mtok", "Cached input $0.25 / Mtok", "Output $7.50 / Mtok" — and the page's own meta description repeats them machine-readably: "Pareto token rates: $2.50/Mtok input, $0.25/Mtok cached input, $7.50/Mtok output." The model card at unbiased.ai/model-card states the same three figures in prose and adds that cached input is billed at 0.1x the input rate. OpenRouter's endpoint list for unbiased/pareto (read 2026-09-18) returns exactly ONE endpoint, provider_name "Unbiased", at prompt 0.0000025 / completion 0.0000075 / input_cache_read 0.00000025 with discount 0, so the maker's own figure and the only routed figure agree to the cent on all three legs. The rate is metered against prepaid credits, but unlike a credits-only vendor it is quoted in USD directly and does not vary with the $10, $100 and $1,000 pack sizes, so there is no pack-size spread to resolve and no promotional or introductory marker appears against it. Unbiased charges this flat rate whichever model a request is blended from — the price is its own, not the routed model's — so the row carries no orchestrator pricing caveat.
Price receipt
Partial receipt. We read Unbiased's own pricing page on , and every price above is printed on it — for each one, Pareto is the nearest model name on the page and no other model we track sits closer. What that capture does not give us is an entry for this model we can parse, so the match rests on where the numbers sit on the page rather than on a row we could read end to end. We keep the page text we read; its content hash is 27661bf629. Check the provider's page before relying on it.
Overview
Unbiased's only model, and a blended one: the platform answers a request by composing across several frontier models behind the scenes and returns a single answer, sold as one SKU under the API identifier "pareto". Text and image in, text out; 262,144-token context and up to 131,072 output tokens on the maker's own endpoint, with tool calling. $2.50/$7.50 per 1M tokens and cached input at $0.25 — a tenth of the input rate, which Unbiased positions as 15-25% of Fable 5's list. Its own model card publishes Pareto 26.9's scores against Fable 5.1, GPT 6 Astra and DeepSeek 4.1 Flash: ahead on ArXivMath (88 vs 72/91/28), level on DeepSWE (74), behind on Terminal-Bench 4.0 (51), MMMU-Pro (78) and HLE no-tools (49). No measured task cost or composite score is published, so the cost-per-task claim the positioning implies is not evidenced by the maker.
