Google says its models are now generally available. What that word should mean to you
Gemini 2.5 moved out of preview yesterday. «Generally available» is a procurement term, and most SMEs have been ignoring it for two years.
Google announced on 17 June 2025 that Gemini 2.5 Pro and Flash are now generally available, describing the change in terms of stability and reliability for production use, and introduced a lighter Flash-Lite variant.
Nothing about the models changed. What changed is a label, and that label is one most SMEs have been running past without noticing for two years.
What the labels actually mean
Preview or experimental. It can change without warning, be withdrawn, or behave differently next week. There is typically no service commitment and no notice period. This is fine for trying something. It is not fine underneath a process your business depends on.
Generally available. The vendor is committing to stability, to notice before changes, and usually to a service level. That is what you are actually buying when you put something into production.
The problem is that preview features are often the good ones, they appear in your existing subscription at no extra cost, and nothing in the interface says « this may vanish ».
Why this matters more after April
The GPT-4o rollback in April showed that even a stable, generally-available model can change behaviour under you. A preview one carries that risk plus the risk of simply disappearing.
If your invoice processing depends on a preview feature and the vendor retires it, you have no contractual claim and possibly no notice. That is a genuinely poor position for something that touches your accounts.
The check worth doing this week
For each AI feature you rely on, find out whether it is generally available or preview. It is usually stated in the documentation and almost never in the sales conversation.
Then apply one rule: previews are allowed for experiments, not for processes. If something in production is running on a preview feature, either accept the risk explicitly in writing, or move it.
The wider habit
This is the same question as the contract-length advice from January, the model-swap question from February and the supplier-governance one from May. All four are asking: what exactly have you been promised, and by whom?
In a field moving this fast, that is the only question whose answer stays useful.
