How we rank
Cheapest LLM APIs stay a strict price board, with a quality watermark so low-cost rows do not hide weak benchmark coverage.
- Eligibility — Chat-completion style APIs with positive priced tiers (we exclude zero-dollar rows here because `/best/free` covers that intent).
- Primary ranking — Ascending input $/1M tokens using consolidated provider data.
- Quality watermark — Rows show the first available MMLU or GPQA Diamond score as a capability check, but the score does not change cheap-page order.
- Variant collapse — We keep one row per model family (`familySlug` + parameter tier). When headline scores tie within ±0.5 pt (±10 Elo on Chatbot Arena), we pick the canonical SKU by lowest tracked input price, then GA over preview or limited access, then newest `release`. A folded sibling within the benchmark noise band can show a "Tied within margin" chip on that score cell.
- Coverage caveat — Ultra-cheap models may lack frontier benchmarks — pair this list with `/best/coding` or another task board for quality guardrails.

How often is this list updated?
The LLM rankings on this page are updated daily as new benchmark scores, provider availability, and pricing data are tracked. The "as of" date at the top of the page shows the most recent refresh.
How do you decide which models appear in the top 3?
The podium picks are driven by the primary benchmark signal for this category (shown in the Methodology section), filtered to non-deprecated models with confirmed API availability. In ties, we prefer the more recently released model.
Are preview or beta models included?
Preview models appear in the "Watch list" section but are not in the main ranked podium unless the category explicitly allows it (e.g., /best/coding and /best/agents, where preview models often lead benchmarks).
Can I compare two specific models head-to-head?
Yes — use the Compare tool at llmreference.com/compare for a side-by-side breakdown of context window, pricing, benchmarks, and provider availability.
Is the pricing data real-time?
Pricing is tracked from provider documentation and updated regularly. It reflects the best available public data, not live API quotes — always verify before billing.
