This morning’s TechCrunch headline was Google cutting prices on its AI subscriptions, a deliberate jab at OpenAI’s consumer tiers. The piece called it a warning shot, and it probably is one. Google can afford to lose money on inference for years, OpenAI knows it, and for a little while the winners are the people paying twenty bucks a month for a chatbot.

So everyone’s cheering. Cheaper AI, good. But I keep looking at this the way you’d look at two airlines undercutting each other on a route you never fly. The price isn’t the part that has you trapped. The tier is.

What a price war is actually buying

When Google drops the cost of its subscription, it isn’t being generous. It’s buying your default. The entire function of a subscription tier is that once you’re inside it, every task you have quietly flows through one provider, because switching feels like effort and you already put the card in. You picked Gemini Advanced or ChatGPT Plus, and now your brain routes every question to the tool you’re already paying for, and that habit is the actual moat. The price cut is just bait that walks you into the pen. Once the competitive heat dies down, the number drifts back up, and you’re still standing in the same spot, paying whatever they decide next.

And the tiers themselves are where the real games happen. The good model is gated behind the higher plan. The rate limits tighten right when you start relying on it. The feature you wanted shipped to the enterprise SKU first. None of that gets fixed by a temporary discount.

BYOK changes who holds the meter

Bring-your-own-key flips the whole arrangement. You hold an API key from whichever provider you like, you pay for exactly the tokens you burn, and no monthly plan decides what you’re allowed to touch. When Gemini 3.1 gets cheaper this week, you aim your key at Gemini. When Claude ships something sharper next week, you change it in a dropdown and move on. The price war stops being a cage and turns into a menu, which is the only sane way to treat a market where the leader changes every couple of months.

We made the data-privacy version of this argument in AI Data Mining Makes BYOK Essential, but the pricing angle is just as blunt: when you own the key, the provider competes for your next token instead of owning your next year.

The agent doesn’t need a price tag either

There’s a second cost these comparisons almost always blur together. The model and the agent are two separate products, and people keep paying for both as if they came welded. You pay your LLM provider for the intelligence. Then a lot of tools charge you again, on top, for the software that points that intelligence at your actual work.

Dassi doesn’t. The agent is free. You bring your own key, or you log in with the ChatGPT subscription you already pay for, and the part that does the clicking and reading and drafting costs nothing.

What this looks like when you actually use it

Picture the most boring version of your week. You’ve got a vendor portal open in one tab, a half-written reply sitting in Gmail in another, and a spreadsheet you’re supposed to fill from a page that has no export button. Every one of those is a browser task, and every one of them is the kind of thing a subscription chatbot can only help with if you copy the page out, paste it into a separate window, wait, and paste the answer back.

Dassi lives in the side panel of the browser you’re already in. It sees the tab you’re looking at, the one where you’re already logged in, so it can read the portal, draft the reply in place, and pull the numbers off the page that refuses to give you a CSV. The model behind it is whichever one you chose this morning. If Google’s price cut makes Gemini the cheap option today, run Gemini today. If that flips, flip with it. The agent doesn’t care which engine you bolted on, because it was never the thing charging you for the engine in the first place. We dug into why the browser is the right home for this in Why Your Browser is the Best Place for AI.

That’s the whole trick. The model is a commodity that gets cheaper while you sleep. The browser is where your work already lives.

So who actually wins the price war

Not the loyal subscriber, weirdly. The person who wins is the one who never committed to a side, the one running a key they can repoint in a dropdown and an agent that costs nothing to keep around while the giants set fire to each other’s margins.

Google fired a shot at OpenAI today. Next month somebody fires back, prices wobble again, and the headlines write themselves. I’ll probably read those too. But I’m not going to reorganize my work around whichever logo is cheapest this week, because the whole point of holding your own key is that you get to stop caring who’s winning.
