Mental model

Optimize for outcome per dollar spent, not for token efficiency—the cheapest interaction is often a different interaction entirely, not a more efficient version of the same one.

Summary

Meta is building data centers in temporary tent structures, borrowing Tesla's playbook to dramatically reduce capital and operational costs for AI infrastructure. This follows months of aggressive spending on compute capacity for training larger models. Apple has approved Poke as the first AI agent on its Messages for Business platform, opening a new distribution channel for AI-powered automation through native SMS and iMessage interfaces. This is Apple's first formal integration of third-party AI agents into a core business communication tool. NVIDIA released Nemotron 3.5 Content Safety, a customizable multimodal safety model designed for enterprise AI deployments. It lets companies fine-tune safety policies without retraining base models, addressing a major friction point in regulated industries.

Ravi Mehta just published a breakdown on what he's calling "tokenmaxxing" — the pattern where AI product teams optimize for feature completeness or model capability without accounting for the actual cost structure underneath. The piece walks through three concrete fixes that can cut token spend by 10x, which is a massive efficiency lever most teams aren't pulling yet.

Here's why this matters for you as a senior PM: we're at an inflection point where AI economics are becoming a first-order constraint on product decisions, not an afterthought. If you're building on top of LLMs or embedding them into your product, you're probably experiencing this already — the unit economics don't work until you get ruthless about prompt design, caching strategies, and when to actually invoke the model versus when to use cheaper heuristics.

The PM angle here is about decision-making under cost constraints that your finance team is now actually asking about. A year ago, "we'll just call GPT-4" was acceptable. Now it's not. You need to understand the tradeoffs between model quality, latency, and cost per transaction. That means sitting down with your eng team and actually mapping where tokens are flowing, then making hard calls about which features justify the expense.

Mehta's framing is useful because it resets the conversation: you're not trying to be cheap, you're trying to be intentional. Some features should absolutely use expensive models. Others shouldn't exist at all if they're just burning tokens for marginal user value.

This is exactly the kind of operational rigor that separates senior PMs from group product managers — knowing when to dig into unit economics and actually change the product architecture because of them.

Here's the thing that most teams get wrong about AI economics right now: they're optimizing for the wrong unit. Everyone's obsessed with token count — how many tokens does my model consume, how do I squeeze efficiency out of the inference engine. But that's not actually the constraint that matters. The real question is whether you're getting behavioural change per dollar spent, and most teams aren't measuring that at all.

Ravi Mehta just walked through this in a way that reframes how you should think about your AI product spend. The mental model is this: tokenmaxxing is what happens when you treat the infrastructure cost as the problem instead of treating user outcome as the problem. You end up optimizing locally — shaving tokens here, compressing context there — while your actual ROI per user stays flat or gets worse.

What that means in practice is you need to flip the question. Instead of asking "how do I reduce tokens," ask "what's the minimum viable interaction that creates the outcome I want?" Sometimes that's fewer tokens. Sometimes it's a completely different interaction pattern. Sometimes it's realizing you don't need the AI call at all.

Think about it like this: imagine you're building an AI-powered customer support tool. You could spend engineering cycles optimizing your prompt to use fewer tokens, maybe cut your token spend by 20 percent. Or you could step back and ask whether the customer actually needs a full AI response, or whether a well-structured knowledge base with AI-powered search gets them to resolution faster and cheaper. The second path might cut your spend by 10x, but only if you're measuring resolution time and cost per resolution, not token efficiency.

The move here is to audit your AI features this week with one specific lens: for each AI call you're making, what's the actual user outcome you're trying to create, and what's the cheapest way to create it? Not the cheapest in tokens — the cheapest in total product cost. You might find that some features don't need the latest frontier model. Some don't need real-time inference. Some don't need AI at all.

Start with your highest-volume AI feature. Map the user outcome. Map the actual cost per outcome. Then ask: if I had to cut this by half, what would I cut? Usually that exercise surfaces the real optimization opportunity, and it's never just "use fewer tokens."
