Why did Microsoft pause GitHub Copilot signups?

Microsoft grounds Copilot signups amid capacity crunch

Microsoft has paused new GitHub Copilot account sign-ups for several subscription tiers, including Pro, Pro+, and Student. It also tightened usage limits and removed certain Opus models from Pro, while restricting Opus 4.7 availability to Pro+.

The practical effect is that some new customers can’t immediately start using Copilot under the previously available plan mix, and existing users may see stricter ceilings on how much Copilot can be used during the billing period.

What changed

• New sign-ups are paused for Pro, Pro+, and Student tiers.
• Usage limits were tightened across the affected plans.
• Opus model availability was reduced: Opus models were removed from Pro, with Opus 4.7 limited to Pro+.

Why it matters

Copilot is one of Microsoft’s most visible “AI at work” products, and sign-up pauses are a signal that underlying demand and/or compute capacity has outpaced what Microsoft can support at the old terms. In other words, pricing and packaging are being adjusted not just for product strategy, but for operational constraints.

These kinds of gating and entitlement changes also shape developer expectations. For teams trying to roll out AI assistance, sudden plan restrictions can create procurement delays and force workarounds (for example, switching tiers or changing workflows).

More broadly, the move reflects a recurring pattern in generative AI markets: as usage rises quickly, providers often ration access via plan limits, feature gating, or model tiering until capacity and cost structures stabilize.
