How to choose

Key Takeaways

The best value model is GPT-6 Luna by OpenAI with a provisional Score/$ ratio of 111.8 (score: 55.9, output: $0.5/1M tokens).

The best open-weight model is MiniMax M3 at position #2.

24 models are ranked here; 1 tracked model is listed without a position.

Score in Context

What these scores mean

Value scores divide the weighted reasoning score by output token price (per 1M tokens). Higher means more capability per dollar. Models with no listed price are excluded.

Known limitations

Value rankings favor cheap models even if absolute performance is modest. A model scoring half as well at one-tenth the price wins on value — but may not meet your quality bar. Always check raw scores alongside value rankings.

About this ranking

Ranking data as of October 8, 2026

Reasoning models tend to be the most expensive tier — they use chain-of-thought, produce more output tokens, and are priced accordingly. This ranking divides each model's weighted reasoning score by output token price, revealing which models deliver the best abstract reasoning, long-context comprehension, and multi-step logic per dollar. For applications that need strong reasoning without frontier-model budgets, the value leaders here are worth serious consideration.

Unless noted otherwise, ranking surfaces on this page use BenchLM’s provisional leaderboard lane rather than the stricter sourced-only verified leaderboard.

GPT-6 Luna leads this ranking with a score of 111.8, followed by MiniMax M3 (66.17) and GPT-5.6 Luna (45.42). There is a significant gap between the leading models and the rest of the field.

The best open-weight option is MiniMax M3 (ranked #2 with a score of 66.17). Open-weight models are highly competitive in this category — self-hosting is a viable alternative to proprietary APIs.
