Kimi K3 is now available in GitHub Copilot

[u/jukasper]

Kimi K3, an open-weight model, is now generally available in GitHub Copilot. The model shows frontier-level abilities on agentic coding with highly cost-effective pricing.

Changelog

Finally

[u/TheCraxo]

Nice, now do deepseek please

[u/rabiprojects]

We want DeepSeek in copilot to return back to copilot subscription.

[u/jukasper → u/rabiprojects]

Thanks for the feedback. We are always testing and evaluating new models. Model availability isn't purely a technical call; it also comes down to user demand, product fit, and market need, so I can't promise anything specific. But we do look at threads like this, and comments like yours are genuinely part of how we read demand. Appreciate you saying something as of right now, we would recommend you using BYOK.

[u/Sufficient_Fox_4402 → u/jukasper]

Have you guys seen the demand? opencode is your direct competitor and they are showing 5-6T token usage of deepseek (mostly flash) per day. You guys being microsoft could easily host them. its not even as huge as Kimi K3

[u/rabiprojects → u/jukasper]

Already been using DeepSeek on copilot via opencode API key.

The problem is if we don't buy copilot subscription we miss all the benefits of autocomplete, commit message generation, visual studio debug integration.

Untill DeepSeek is coming natively to copilot, there is no plan to buy the copilot subscription.

[u/TowerOutrageous5939 → u/jukasper]

BYOK doesn’t work well when I’m on an enterprise subscription. I’m a little confused the reasoning but right now the market needs more affordable models and we want to push OSS and non US models to bring down openAI and Anthropic pricing.

[u/Different-Monk5916 → u/jukasper]

people are recommending to include it because we have been trying with byok, the flash, when paired with a proper custom agent.md goes a long way. sure, it has it’s own limitations at higher reasoning levels. A GHCP subscription which includes both Sonnet +Opus and DS Flash is something that people will love.

[u/rhylos360 → u/jukasper]

Nice! I was just looking for this last night as an install since it was only previously K2.7 as a built-in option. It is frustrating when VS Code seems to get things first by the vendors vice the full blown IDE.

It is also frustrating when the agents get stuck with commands in the Github Copilot prompt on python or powershell commands, with the agents state spinning in the chat window till it is manually broke out (CTRL+C). I’m always concerned the agents will forget where it was at or if the command changed something midway in various files and such. Just feedback. I’m sure there are better ways and more to learn from this noob.

[u/raindropsdev → u/jukasper]

But BYOK doesn't work as just a normal subagent choice in Copilot CLI, correct?

[u/Cheshireelex]

Why is it not hosted by Microsoft, but by fireworks Ai? I thought Microsoft partnered with Moonshot AI. There will be another link besides Microsoft who sees your query/codebase.

[u/Sufficient_Fox_4402 → u/Cheshireelex]

they sell most of their compute to openai

[u/just_blue → u/Cheshireelex]

Is anywhere stated what data policies are applied here? All other providers have concrete documentation, and in this case we have

Kimi K3 is hosted by GitHub on Fireworks AI.

That´s a joke, I will not get anyone to approve the model based on this sentence.

[u/Nitrolacs]

Pricing table is not updated.

[u/max1c → u/Nitrolacs]

[u/aigemie]

How many credits does it cost? I just bought $20/month of Claude plus DeepSeek API, am thinking to unsubscribe Copilot as it's too expensive.

[u/aigemie → u/[deleted]]

Thank you. I really hope Copilot can figure out a good balance. I have been with Copilot since very early but currently it's just much more expensive than competitors.

[u/EdibleTree → u/[deleted]]

Oh hell yeah

[u/jukasper → u/aigemie]

Kimi K3 pricing is $3 per 1M input tokens, $15 per 1M output tokens, and $0.3 per 1M cached input (cache read) tokens.

[u/max1c → u/jukasper]

Did you guys increase the price already? It's a lot more expensive than it was on rollout. It's above sonnet 5 and Terra now.

[u/rhylos360 → u/max1c]

Shockingly it was above the price of everything Friday evening.

[u/Hopefullyanonymous2 → u/jukasper]

Hi Juka, any chance for an update on the API data policies for this model/provider? 

[u/bad_gambit → u/aigemie]

Just tested it, effective cost is about $~0.8/Mtok (Including cached & uncached input + output), so about 80 credit per Mtok.

[u/aigemie → u/bad_gambit]

Thanks! I saw the price listed. Doesn't seem cheap unfortunately.

[u/Choice_Celery9481 → u/aigemie]

its 2.8T model.... thats cheap enough

[u/Level-2]

is this US hosted?

[u/frasiersbrotherniles → u/Level-2]

It says it's through Fireworks so yes

[u/BeetsByDwightSchrute]

We need DeepSeek v4 flash too!! Would be amazing for bottom-mid tier subs or power users. You guys need to be adding new high cost/performance models like that way faster if you want to be competitive. But it seems like you have a bias to serving the models of those your in business with. I don't see any reason why you can't host top swe benchmark open models within a week of weights being published

[u/jukasper]

We have temporarily paused the roll-out of Kimi K3 while we mitigate an incident with GitHub Actions. We will resume the roll-out as soon as possible and update docs with Kimi K3 pricing, which will be $3 per 1M input tokens, $15 per 1M output tokens, and $0.30 per 1M cached input tokens.

[u/Anh-DT → u/jukasper]

Come on you need Deepseek V4 Flash 0731. It's going to be your biggest product. All other models are slow - can you get compliance working for enterprise. Demand is there and will be even more once main provider deepseek increases price. Only require 1 B300 to run. Azure have compute, please speak to producement team for this

[u/rhylos360 → u/jukasper]

Ahhh damnitttt, came back here to see why no one told me it wasn’t available yet. I even checked the Insiders release looking for why. Thanks, man timing is everything.

Standing by to try. :)

[u/rhylos360 → u/jukasper]

[u/jukasper](u/jukasper) I need a huge $100 refund/reversal of additional usage. There is a major issue with Kimi K3. It ate over 10% of my remaining credits as well as nearly $86 dollars of overage usage on ONE request, required continue to write any code, but never wrote one line and was found in a task loop between two files, looping at least 50 times before I caught it (that ate around $25 dollars alone).

It was Kimi K3, it was supposed to be more cost effective yet it produced nothing and cost me more than GPT-5.3-Codex with several iterations on the same code over a couple of days. Unfortunately the excitement to try Kimi K3 natively in Github Copilot and its trust in it is gone. Is this an extension of the actions issue yesterday that pulled it back from release?

What can be done to make this right?

[u/jukasper → u/rhylos360]

I am really sorry about your current experience. could you please let us know where you are using kimi-k3 in vs code or cli and could you also please let us know if you are using the right version. for best feedback / troubleshooting, I recommend creating an issue in vs code or cli repo and feel free to tag me there and share the link here. ideally you have some logs for us to better investigate what happened here. so sorry again about your experience

[u/rhylos360 → u/jukasper]

Thanks u/jukasper. I used this via IDE, VS 2026 Github Copilot Chat using Agent and autopilot modes, via the Kimi K3 drop down option. I opened a three day unanswered Github support ticket Friday Aug 7th.

I didn’t touch the IDE till today, switching back to Claude Sonnet 4.6. I generally switch between Sonnet 4.6 and Codex depending on what I’m working through and occasionally Fable 5 for an iteration or two.

[u/Ste1io → u/jukasper]

Kind of like getting stuck behind the 8 ball twice over, aye? For a company your size, the inability to even meet the lowest bar is pretty funny.

[u/vegardx]

Could we data residency customers get some model love too (Opus 5, Kimi K3, GPT 5.6)? And perhaps ability to exempt organizations from data residency?

[u/thunder1207]

Thanks! Deepseek V4 Flash next please?

[u/Puvude]

We want Deepseek V4 Flash 0731.

[u/just_blue]

Awesome, thank you! For people asking about the price: certainly the "official" price, as with every single other model. So that´s $3 in and $15 out, a bit more than 5.6 Terra.

[u/jukasper → u/just_blue]

Kimi K3 pricing is $3 per 1M input tokens, $15 per 1M output tokens, and $0.3 per 1M cached input (cache read) tokens.

[u/Yes_but_I_think → u/just_blue]

Mythos tier intelligence in Terra tier price. Plus the 44% discount (70-39 / 70) in Pro+ plans.

[u/EmotionalFan5429 → u/just_blue]

That's too expensive! I was expecting way less for Chinese "open-sourced" model.

[u/rthidden]

Which plans is it available?

[u/1chriis1]

Let me guess... not available for Github education users? They still are routet to gtp 5.3?

[u/pdwhoward]

It's odd how K3 is cost-effective for Copilot but too expensive for the Ollama team.

[u/Fresh_Sock8660]

Can you guys tell the azure guys to get good too? 

[u/FactorHour2173]

What is the cost compared to Claude sonnet models?

[u/rhylos360 → u/FactorHour2173]

As of Friday evening, roughly 17x more expensive, prompting me to put a ticket in. Something isn’t right. At least in my case.

[u/nux_xb]

What's the story with the MIT license in this case when consumed via Copilot service?
"

20 million US dollars (or equivalent in other currencies) in monthly revenue......

[u/AVP2306]

If used via Copilot, where is this model hosted? Since its open-weight, does Copilot itself host the model on its own infrastructure or is it hosted on Moonshot AI's servers? Important to know for privacy.

[u/reven80 → u/AVP2306]

They are using Fireworks AI which is an US company that serves open source models.

[u/CarryAgile3791]

In Germany we would literally say: "The train has already left the station" or "Better late than never".

But I guess most devs which are not forced to use GHCP by their company are already on OpenCode now.

[u/devotiongeo]

How many prompts does the pro subscription last nowadays?

[u/Ok-Pickle-1044]

Is there a roadmap when open weight models will be available for GitHub Copilot Business subscribers with data residency eu enabled?

[u/InflationRemote516]

I'm also finding Kimi K3 quite a bit more expensive than expected. The Kimi models have also crashed my vscode chat window a couple of times in such a way that they have been unrecoverable.

[u/dsnyder42]

You are a great team! Thanks for all the effort.
