MAI-Code-1-Flash is now available for GitHub Copilot

[ebndev]

MAI‑Code‑1‑Flash, Microsoft's latest small‑tier coding model, is now rolling out in GitHub Copilot starting with VS Code. MAI‑Code‑1‑Flash delivers best‑in‑class quality for its size, outperforming other small models in early testing, making it well‑suited for lightweight coding workflows. Designed and tuned specifically for GitHub Copilot, this marks the first in a new wave of purpose‑built coding models from Microsoft.

Availability in GitHub Copilot

MAI‑Code‑1‑Flash is beginning to roll out to Copilot Free, Pro, Pro+, and Max plans. Availability will start with a limited set of users and expand gradually over the coming weeks.

You'll be able to select the model in the model picker in

• Visual Studio Code

More than interested to try when it comes out. But what about the full fledged Thinking version?

[natestrom]

Definitely looking forward for the new MAI models to land on Business/Enterprise accounts!

[ederbond]

Is it going to be available to download and run completely offline on my own hardware with the full fledged Visual Studio 2026 IDE?

[francovp]

Why no business or Enterprise? :(

[spoiledsport]

WHy not Visual Studio?

[drewid]

100%. About to dump tooling due to the 20x-30x increase in costs with GitHub Copilot and this is maybe the only thing that would save it.

[okasi]

Will it be uploaded to hugging face?

[mindplay-dk]

Put it up on OpenRouter so we can try it, please - and so we can see how much it really costs.

[OminousIndustries]

Put it up on OpenRouter so we can try it, please - and so we can see how much it really costs.

Agree with this. As far as releases go this one is making it rather difficult to even try the model

[mindplay-dk]

They have the other MAI models (image, voice, transcribe) already up there, so presumably it's coming.

[chriddyp]

This is looking great! Would love to try it out and benchmark it in Plotly Studio for data visualization and analytics workflows. Will this be available as an API on Azure or Open Router? Or only integrated in product suites?

[winter123123]

Why are business/enterprise users not supported?
Costs have already increased due to the shift to a pay-as-you-go model, so why do we have to face this kind of discrimination?
If this is how we are treated, we will stop using the enterprise service.

[drewid]

When can we get this in regular Visual Studio? About to dump tooling due to the 20x-30x increase in costs with GitHub Copilot and this is maybe the only thing that would save it.

[tfukumorikkmic]

I agree.

[gimlichael]

Eager to try this - I need a replacement for Claude Haiku 4.5 - and this looks like the sweet spot. When will it be available? I am on the Pro+ and already 2 day has passed 🐌

[erincon01]

I don't see MAI in my ghcopilot business. Is this expected?

[MihailCosmin]

I also don't see it as of 08 June
Is this an US, EU rollout issue ?

[eugenenell2021]

When will MAI be available for Enterprise GitHub Copilot? Why are business/enterprise users not supported as yet and how long will it take before we get it?

[oduis]

Could it be that "available" just means "for inline code completion", but if never shows up in the models?

[gimlichael]

No - it's literally written that it start with a limited set of users and expand gradually over the coming weeks. Go have a look at YouTube - people lucky enough to get the model are quite pleased with it. And i actually think that Copilot will have value again as I assume Microsoft can provide these models cheap (since they own everything tied to it).

[oduis]

Thanks, just watched the Youtube demo.
Unfortunately, the price is exactly the same as GPT5.4 mini: GitHub Model prices
From the SWE Pro bench MAI-Code-1 and GPT5.4 mini seems to be in the same ballpark, and I found the latter really usable for its size.
I would have hoped for a lower cost one like the Microsoft Raptor model though.

[gimlichael]

At least for me, it looks like a solid replacement for Claude Haiku 4.5 - but time will show 🤞🏼

[tanvishinde017]

Thanks for bringing MAI-Code-1-Flash to GitHub Copilot.

It's great to see more purpose-built coding models being added to the ecosystem. Having efficient lightweight models is especially valuable for quick edits, smaller projects, and reducing overall credit usage.

Looking forward to trying it out in VS Code and seeing how it compares with the other available models. It would also be interesting to see future benchmarks and broader availability across additional Copilot surfaces.

Hallo, aus Deutschland 🔰 🎉

[justinoneten]

I'd love to hear the line of thinking as to why this was rolled out to individual accounts first vs. business / enterprise. Shouldn't users paying for a premium product have the earliest access?

[Jaimi]

So those of us paying for the higher tiers in individual plans are not paying for "Premium Product"? I beg to differ.

[justinoneten]

@Jaimi You are, but they're rolling it out across the board for individual plans, including pro ($10/mo) and even free users before business ($19/mo) and enterprise ($39/mo).

I'd totally get it if they rolled it out by monthly plan cost – Max, Pro+, Enterprise, Business, Pro, then Free – but they're giving it to free users before business users, which seems like a real slap in the face for people who are actually paying consistently to use the service.

[Jaimi]

I see what you mean. But look at it this way - if it goes catastrophically bad, it's better for them to test i on those accounts.

[ederbond]

Microsoft's free plan in VS Code, its terribly small. Tested it on a small ASP.NET WebAPI app the it's consumed 23% in a single small change of creating a db migration in a small project. It was in High thinking mode. It will be like a 1 ~ 3 days trial.

[ederbond]

If they don't want to lose, even more developers from their ecosystem to other platforms, or they should release it to public to be downloaded and run locally on the developers machine. At least a full version of it to run for free or a variant the allow at least .NET full agentic programming, with the goal do run it locally and Free (at least for .NET) it will be the only effective way to contain the competition to defeat you) you're otherwise the competition might defeat you.

[PeterLeeSAG]

May I know how to apply or select it in the agent mode on the web UI? I can't see it on the page of the agent mode.

Does MAI-Code-1-Flash support vision capabilities?
