Kimi Allegretto costs $39/mo; ChatGPT Plus costs $20/mo. Kimi's higher price does not buy comfortable headroom because its shared credits drain too quickly.
ChatGPT Plus vs Kimi Allegretto: choose ChatGPT Plus. Measured on ChatGPT Plus, one pass of our fixed task set fits about 85 tasks a week with GPT-6 Astra. Kimi Allegretto costs $39/mo; ChatGPT Plus costs $20/mo. Prices are the providers' own list prices, and the verdict is ours rather than a score.Measured
Our verdict
Choose ChatGPT Plus. Kimi can produce good visual design, but its limit empties far too fast to recommend. Long context and parallel agents don't help when ordinary use empties the plan this fast.
ChatGPT Plus costs less and gives you every OpenAI model in Codex.
$20 gets you Codex with every OpenAI model, including Astra. Luna handles high-volume small tasks at a fraction of the quota. OpenAI's extra resets are getting fewer and fewer, so don't rely on them lasting much longer.
Pros
Every OpenAI model, including Astra
Luna is cheap on quota
Generous allowance while the extra resets last
Cons
Opus 5.5 is stronger at the same price
Astra can drain the whole 5-hour window in one prompt
The current allowance depends on temporary extra resets
Best for People who want Luna for high-volume small tasks.
How far it goes: at least 15 times a week, and more than 100 for the cheapest model
Our whole real-world issues and spec planning pass runs at least 15 times a week, and more than 100 for the cheapest model on this plan, depending on which model you run.
That works out at about under 5c to 28c of the subscription per run, at the list price.
Measured on this plan, at <1% to 6%/1w of its allowance per run. A share belongs to the plan it was measured on, so we never subtract one plan's from another's.
Allegretto gives K3 more credits and parallel agents. The shared limit still runs out before ordinary work is done. K3 has also regressed in our use since release. We do not recommend it.
Pros
Good visual design
Long context
Parallel agent tools
Cons
The limit drains too quickly
K3 has gone backwards in our use
Best for Nobody.
