The cheapest open LLMs to run via your own API key

Open LLMs ranked by their real, dated $/1M-token price (blended input+output) on your own API key — cheapest first, $0 markup. This list only includes models we have an actual, verified price for; we never pad it with size-based guesses. The $0-on-your-own-hardware and rent-a-GPU options are shown on each model's page.

How this is ranked: Built only from real, dated prices in model-prices.ts — size-estimated models are EXCLUDED from this ranking entirely (so no fabricated figure can drive the order). 'Cheapest' is a measured dollar amount, not a quality claim; open the advisor for your exact workload.
