AI Weekly: Copilot Billing Shake-Up and Microsoft's Own Models — June 1-7, 2026

June opened with a pricing change that will hit a lot of teams and a batch of new models from Microsoft. GitHub Copilot moved everyone to usage-based billing, and Microsoft used its Build conference to unveil seven of its own models. If your business pays for Copilot, the billing change is the one to read carefully, because your costs could shift without you touching a thing.

The Deep Dive: A Copilot Bill Shake-Up and Microsoft's Own Models

GitHub Copilot switches to usage-based billing

On June 1, GitHub Copilot moved every plan to usage-based billing built on "AI Credits", where one credit equals one cent and you are charged on token consumption. Pro stays $10 a month with $10 of credits included, Pro+ is $39 with $39 included, and code completions remain unlimited. The catch is that heavy chat or agent use can now burn through your monthly allotment and tip you into overage.

If your developers lean on Copilot's agent features, your bill could climb even though the headline price looks the same. This is worth modelling before the first invoice surprises you.

Microsoft unveils seven in-house models at Build

On June 2, Microsoft launched a family of seven MAI models trained from scratch, including its first reasoning model, a fast coding model, and image, transcription and voice models. The goal is openly stated: cut costs and reduce reliance on OpenAI. For businesses inside the Microsoft ecosystem, that should mean cheaper AI baked into tools you already use.

Google also released Gemma 4 12B, an open model capable enough to run on a laptop with 16GB of memory.

Why this matters:

• Usage-based billing means your Copilot cost now depends on how heavily your team uses it, not a flat fee.
• Microsoft's own models should push down the cost of AI inside Office and Azure over time.
• A capable model that runs on a laptop lets privacy-conscious businesses keep data on their own machines.

What This Means for Australian SMEs

If you pay for Copilot, do the sums this month. Under the new model, a small team that uses the agent heavily could pay noticeably more, while a light-touch team pays about the same. Neither is bad, but you want to know which one you are before the bill lands.

The broader trend is helpful. As Microsoft builds its own cheaper models into its products, the AI you get inside Office and Windows should improve without a separate subscription. And an open model that runs on a laptop is a genuine option for any business that cannot send sensitive data to the cloud, common in Australian health, legal and finance work.

The practical takeaway for this week:

• Check your Copilot usage against the new credit allotment before you get an overage surprise.
• Watch for Microsoft's own models showing up in tools you already pay for. Often they cost you nothing extra.
• If data privacy is a hard constraint, test whether a laptop-run model like Gemma 4 12B fits your needs.
