# Cheaper alternatives to Kimi K2.5

Moonshot AI · LMArena 1445.2 · $0.900/M on a balanced workload · prices as of 2026-08-28

## Everything cheaper and higher-scoring gives something up.

Of the 133 models carrying both an independent score and a published price at the same delivery mode, **4** score at least as high as Kimi K2.5 and cost no more under at least one workload. **4** do not, and every row names what it drops.

Dominance is not a property of a model. It is a property of a model, a capability lens and a workload, and all three are named on every row. Scores are LMArena Elo, used under CC BY 4.0 from the official dataset; prices are blended per million tokens. A higher score is not a drop-in replacement.

This page is built from that comparison and nothing else. When no model is both better and cheaper than Kimi K2.5, it is not generated.

## Where it holds

| Workload | Kimi K2.5 $/M | Better and cheaper | With a trade |
| --- | --- | --- | --- |
| Balanced | $0.900 | 0 | 3 |
| Summarise | $0.432 | 0 | 3 |
| Chat | $1.06 | 0 | 4 |
| Code gen | $1.50 | 0 | 4 |
| Agentic | $0.494 | 0 | 3 |

Workload mixes are defined on the [methodology page](/methodology/). Cached input is priced at the cached rate, and reasoning tokens at the worse of the reasoning and output rates.

A replacement has to clear every line above, not just the score. [Full record for Kimi K2.5](/models/moonshotai__kimi-k2.5/).

## Cheaper and higher-scoring, but you give something up 4

These score at least as high and cost no more on the two plotted axes, and lose something that is not on them. Read the last column before switching.

## What this compares, and what it leaves out

 - Quality is LMArena Elo, used under CC BY 4.0 from the official dataset. The 95% confidence interval on a difference between two scores is about ±10.68 points, so a gap smaller than that is marked *tie* rather than an improvement — see [significance bands](/significance/).
 - 188 further models at this delivery mode carry a price but no independent score. They are absent from the comparison in both directions — unrated is not a zero, and an unmeasured model is neither an alternative nor a worse buy.
 - Retired models are never offered as an alternative, and a model only competes against its own delivery mode: batch trades latency for price, so it is not a like-for-like swap.
 - Nothing here measures latency, throughput, rate limits or how a model behaves on your prompts. Two models with the same index score are not interchangeable.
 - The models that nothing beats on both axes are on the [value frontier](/frontier/), and every other model something cheaper beats is [listed here](/alternatives/).
