I prepaid for a ton of DeepSeek v4 flash tokens. When I use them I would like to try purchasing Luna tokens for a while. I like cheap and fast models and since I am retired, if I waste time having to sometimes manually switch to a stronger model, that is OK with me.

What are your use case for these? I’m manly interested in coding where more capability is better - give me a 10x model at 10x the price and I’ll take it. A worse model at very low cost has no appeal to me. At-least not for coding. Translation maybe? OCR?

Friendly reminder that GPT-5.6 in Codex cannot spawn Luna subagents, only Terra [1]

To fix this you currently need to make your own copy of the bundled model catalog [2] and opt Luna into MultiAgent V2.

"too cheap to meter" and Luna is still more expensive than deepseek-v4 pro

This is one of the things OpenAI has been focused on for an year or so that led to the doomed autoswitcher in ChatGPT .com (switching models based on estimated task complexity) that was quickly reverted

Whereas Google with Gemini 3.x, Anthropic with Fable etc are happy to just go for 'big model with dense params'

It's hard to guess from the outside of course but just this kind of talking points focus on GPU efficacy is what we see from OpenAI and Chinese open source labs more often than from Anthropic or Google Deepmind and this benchmark chart seems to concur

> $0.20 per million input tokens and $1.20 per million output tokens for Luna

This is... ridiculously cheap. Amazing!

It says Luna is fastest, but doesn't it take way more steps to get the same job done?

Or is the output speed so much higher that it cancels out?

I don't see a lot of benchmarks that record actual time. But on AA, Sol on Low beats Luna on High for Time Per Task.

It's a clever strategic move: grab the market of cheap low end models within the product range. It's lower friction to switch a model than a provider.

I truly wonder what kind of model is luna now.

Before I thought it was just an improved version or at least in the same class as gpt 5.4 mini but now it's being priced like a nano model!

I thought about it because Terra has similar pricing to 5.4 and Sol is similar to 5.5.

Luna was already my workhorse before, it performs very well on high/xhigh for most of the tasks, very happy about this drop.

I've been having issues with it using unreasonable timeouts for tasks that should have failed within minutes, not hours.
