According to the Artificial Analysis benchmark graph in the article, Luna can now outperform Sonnet 5 and Opus 5 low at ~4-10x less cost

You'd be surprised at what Luna can do, especially on xhigh or max. It's capable of working overnight, usually productively, just like Sol.

Haiku 4.5, on the other hand, is comparable to performance to Gemma4 31B (with working tool call formatting) in my experience, and Gemma4 strongly wins on vision and multimodal.

Per Artificial Analysis:

- Haiku: 30 points

- Luna Medium/High/Xhigh/Max: 38/46/49/51 points

That's a massive difference:

- 30 points is Gemma 4 31B territory

- 50 points is GLM-5.2 (744B) territory.

luna is way better than haiku 4.5
