Kimi K2.7 Code is now generally available in GitHub Copilot, announced in GitHub's changelog on 2026-07-01. The headline is not just a new option: it is the first open-weight model you can pick in the Copilot model picker, positioned as an additional choice and a lower-cost option alongside the existing models.
What Kimi K2.7 Code is
Kimi K2.7 Code is a coding-focused model now offered inside GitHub Copilot. "Generally available" (GA) means it is out of preview and ready for day-to-day use, not a limited test. What sets it apart is its status as an open-weight model, the first of that kind to appear as a selectable option in the Copilot model picker rather than only the closed, hosted models that have filled the list so far.
GitHub hosts it on Microsoft Azure, so from a Copilot user's point of view it behaves like any other model in the picker: you choose it and it runs through GitHub's infrastructure.
Who gets it
Per GitHub's changelog, the GA rollout starts on:
- Copilot Pro
- Copilot Pro+
- Copilot Max
It will expand to Copilot Business, Enterprise, and other surfaces in the coming weeks. GitHub describes this as a gradual rollout while it monitors quality and performance, so if you do not see Kimi K2.7 Code in the picker yet, it may simply not have reached your account. You select it from the Copilot model picker once it is available to you.
What makes it different
The distinctive trait here is the open-weight angle. Every model that has been selectable in the Copilot picker until now has been a closed, proprietary model. Kimi K2.7 Code is the first open-weight model offered as a pick inside Copilot, which is why the announcement matters beyond simply adding one more name to the list.
The second angle is cost. GitHub positions Kimi K2.7 Code as a lower-cost option, an additional choice for developers who want to reach for a cheaper model on routine work rather than always running a premium one. Both points are GitHub's own framing in the changelog, not a performance claim: GitHub did not publish benchmark numbers, so treat this as "another option, cheaper, and open-weight" rather than a ranking against the other models.
How it fits alongside the other options
Copilot's model picker keeps growing, so the real question is which one for what:
- Kimi K2.7 Code: the new open-weight, lower-cost pick, useful when you want a cheaper option in the rotation.
- Closed, hosted models like Claude Sonnet 5: the established selectable models that have filled the picker so far.

How billing works
Kimi K2.7 Code is billed at provider list pricing under Usage-Based Billing (UBB). In practice that means usage is metered and charged at the provider's list rate rather than bundled into a flat allowance. GitHub did not publish a specific per-token figure in the changelog, so check your Copilot billing settings for the current rate before leaning on it heavily. The "lower-cost" framing is GitHub's, but confirm the actual rate in your billing settings rather than assuming a number.
How to enable it
- Make sure you are on a plan in the rollout (Pro, Pro+, or Max first, with Business and Enterprise following).
- On Business or Enterprise, note that Kimi K2.7 Code is disabled by default: a plan admin must enable the Kimi K2.7 Code policy in the Copilot settings before anyone can select it.
- Open the Copilot model picker in your IDE or CLI.
- Select Kimi K2.7 Code, and check your Usage-Based Billing settings to keep an eye on usage.
The bottom line
Kimi K2.7 Code reaching general availability in GitHub Copilot matters mostly for one reason: it is the first open-weight model you can pick in the Copilot model picker, offered as an additional, lower-cost choice and hosted by GitHub on Microsoft Azure. The GA rollout starts on Pro, Pro+, and Max, expanding to Business and Enterprise in the coming weeks, where an admin must switch on the policy first. Billed under UBB at provider list pricing, it is worth a try when you want a cheaper option in the mix.
