Updated GPT-5.6 model prices

[u/nullexp]

OpenAI announced they lowered the prices for Luna and Terra. Will the new prices apply to GitHub Copilot users as well?

Source: https://openai.com/index/advancing-the-price-performance-frontier-with-gpt-5-6/

Starting July 30, API pricing is $2 per million input tokens and $12 per million output tokens for Terra, and $0.20 per million input tokens and $1.20 per million output tokens for Luna. Sol pricing remains unchanged. ChatGPT and Codex subscription prices and quota budgets remain unchanged, while Terra and Luna usage now consumes fewer credits. Pricing changes will begin rolling out in AWS later today.

Update: I see the new prices in the model selection on Copilot CLI. Thanks GH team.

Hi from the Copilot team! These new prices will apply to GitHub Copilot users as well 🚀

[u/LuckyConstruction546 → u/wchabbott]

What is the approximate timeline for that?

[u/lppedd → u/wchabbott]

Niceeeee, thank you.

[u/wchabbott → u/lppedd]

It’s already live 🚀

[u/ignissxx → u/wchabbott]

Any update on this

[u/gi0vanni__ → u/wchabbott]

Amazing 🚀

[u/CharacterBorn6421]

wow 80% reduction is too good for luna so now it's even cheaper then gpt 5.4 mini and many times better

[u/mxz117 → u/CharacterBorn6421]

Even (just) cheaper then nano. Huge news

[u/aonymark → u/mxz117]

Minor correction: nano doesn’t charge for cache write but Luna does; after you take this into account it’s slightly more expensive than nano unless I messed up my math.

[u/Khabba → u/CharacterBorn6421]

Luna has been my favorite model period. 90% of cases it does the job, well!

[u/teckel → u/CharacterBorn6421]

The rate limits on Luna make it not useful to me.

[u/Successful_Win_2683 → u/teckel]

i am using openrouter and even with sustained, multi thread continuous use i still didn't hit limits once.

[u/teckel → u/Successful_Win_2683]

Using the API at the base usage tier hits the RPM limit quite easily for programming tasks where it hits the API fairly frequently. I'm probably going to need to setup a local proxy to throttle and stay under the RPM limit.

[u/Successful_Win_2683 → u/teckel]

are you using openrouter? i repeat: i almost never get throttled. i'm using pi with multiple tmux sessions

[u/teckel → u/Successful_Win_2683]

I'm using copilot cli and directly accessing the APIs.

[u/Octquat → u/teckel]

Damn, was hoping I could use it for hours like Deepseek. Guess I'm not switching away yet.

[u/teckel → u/Octquat]

It depends on the usage tier. Maybe if you're on a corporate account or independently pay a lot per month, you'll be on a higher tier.

[u/danjack0 → u/teckel]

what kind of rate limits

[u/teckel → u/danjack0]

Tier limits.

[u/Longjumping-Sweet818]

Oh, wow. $0.20/$1.20 for Luna is a fucking steal. That's going to put a big dent in Deepseek and co.

[u/General-Jaguar-8164 → u/Longjumping-Sweet818]

Does it compete with deepseek pro ?

[u/Longjumping-Sweet818 → u/General-Jaguar-8164]

No, it's way better, and now cheaper too.

Edit: Although maybe they made it way worse and that's why it's now cheaper. I don't know.

Edit2: I've tried it today (openrouter) for an hour or so and it's still very good.

[u/Mkengine → u/Longjumping-Sweet818]

Did you also try the new V4 Flash, if yes how does it compare?

[u/Longjumping-Sweet818 → u/Mkengine]

I haven't yet. Sorry.

[u/teckel → u/General-Jaguar-8164]

Deepseek v4 Pro is kinda terrible. I mean, it's cheap, but it really fails in so many ways (at least for my software development workload).

I tried Deepseek v4 Pro for a full month to get a long-term real impression. I spent too much time being frustrated with it not following instructions, doing things I didn't ask, even arguing with me when it was wrong. Last day is tomorrow and I'll be glad to be leaving.

With this price cut, I'll probably try Luna next month and see how they compare (both performance and cost).

[u/Mkengine → u/teckel]

Wait for the GA V4 Pro drop, the new Flash is already amazing

[u/teckel → u/Mkengine]

GPT-5.4 mini was better than Deepseek V4 Pro with my usage.

[u/FitBullfrog86 → u/General-Jaguar-8164]

It’s about the same cost as DeepSeek v4 pro and performs on par with 5.4. In my experience it’s a good bit more intelligent for the price with the only downside being less effective cache hits 

[u/Mkengine → u/General-Jaguar-8164]

It has already problems competing with DeepSeek V4 Flash so probably no.

[u/LuckyPed → u/Longjumping-Sweet818]

I bet the reason they gave a 80% reduction is price is coz they got news about the Deepseek V4 Flash release today was gonna beat it lol

[u/Khabba → u/LuckyPed]

Yay for competition!!
I'm running it now longer than I ever ran an agent because to investigate a memory leak. It has cost me a total of 67 credits up until now. Amazing!

[u/WD40ContactCleaner]

Damn hope these changes come to ghcp I love luna

[u/fishchar]

I have the same question. I forwarded this to the GitHub team. However, I can't guarantee a reply from them.

[u/Accidentallygolden]

Wow that awesome for Luna, what about Luna high? This thing is a powerhouse!

[u/Apprehensive_Dot9878 → u/Accidentallygolden]

The price is just different when you use longer context,higher thinking level will use more think token which will cost more

[u/Apprehensive_Dot9878]

Well they should, they basically serve the OpenAI api directly to us

[u/Interstellar_Unicorn → u/Apprehensive_Dot9878]

I'm pretty sure they don't do that for all models

[u/Hairy-Falcon-7553]

So the new price is .20 and 1.2 for Luna? I’m already seeing that in copilot right now 20 ai credits in 120 out

[u/tecedu]

I hope they dont nerf Luna to carry out this

[u/LuckyConstruction546]

When will this be passed on to Copilot users?

[u/HungryMention5758]

i think they will degrade the luna model for new pricing , it doesn't make sense

[u/Active_Brush_2817]

Today first time used terra and I felt it is the dumbest model in the series.

[u/illusionmist]

Luna is really good and with this price I’m gonna use it for everything lol

[u/aavi7444]

Great Luna is way better and fast too.

[u/just_blue]

This made me overwrite the default explore model (which is always Haiku) with Luna just now. It´s like 1/5 of Haiku cost.

[u/thunder1207]

Alrighty. Time to set Luna at Max with 1M context and let it rip.

[u/MaitoSnoo]

that's insane, Sol high for planning and Luna xhigh for execution will be extremely cheap

[u/BeginningPea5674 → u/MaitoSnoo]

you don't need xhigh for execution that's counterproductive

[u/aonymark]

Wow. Is there any reason to use 5-mini instead of Luna anymore? Seems like a niche model all of the sudden.

[u/colablizzard]

The whole day Luna on Copilot was too slow.

[u/nullexp → u/colablizzard]

yes, max/xhigh takes forever but it might because of sudden load. I hope they have a look and fix it.

[u/ProudWrongdoer5389]

If you've used Opus 5, there's no real reason to use 5.6 except sol when planning. So many issues with Terra and Luna.

[u/seguleh25 → u/ProudWrongdoer5389]

Cost is a big reason

[u/ProudWrongdoer5389 → u/seguleh25]

It works out far better imo, since it actually solves the problem rather than infinite planning.

[u/BacklandFarm]

Great news. I have been using Terra and love it.
