I'm currently spending $200 for Claude. That's around my maximum that I can afford. I could stretch that to $500 I guess. But I saw reports of people spending tens of thousands of dollars with Claude API. That's certainly outside of my budget.
So if/when Anthropic decides to stop subsidizing subscription (if they ever do that thing, I still not sure about that), I'll certainly look at the other options. And available "open weights" LLMs hosted by someone will be my first pick. Right now Claude 4.8 feels very advanced, but things move very fast...
whats the basis for this thought
Again, for Claude, (2) it’s rumored that their API rates have around a 90% profit margin. It’s also claimed that the subscription limits get you around 10x tokens per monthly dollar vs buying them with API rates.
Edit: to drive it home. If a tokens true cost to anthropic is 1/10 of what they sell it for at API rates, and a subscription gets you tokens at 1/10 the price, that’s cost-neutral for the business if every subscription uses every token. They’re selling tokens at cost, not at a loss. Many subscription users won’t use their full allotment. That means serving some users doesn’t cost the business as much - which might push the subscription business from cost neutral to profitable.
Or, maybe I'm wrong, but my understanding is: MoE is just an architecture to keep the activated weights smaller per token. The experts get routed basically token-by-token, and the "experts" themselves don't have a semantic domain so the "expert" word was maybe a poor choice.
You talk to a smart, heavy model to build a plan composed of smaller steps. Then you have the heavy model spin up smaller, cheaper LLMs to actually implement the tasks.
The heavy model is basically read-only in that mode. It can read files, execute tests, etc, but it can’t write code. It just tracks what needs to be done, offloads the work to dumber LLMs, validates the task is done, and moves on to the next step.
It sort of pushes humans up the stack. Instead of having a human sitting there prompting the LLM to start the next task, you have another LLM do that loop.
It’s been on my list to try out.
"The sparsely-gated MoE layer,[21] published by researchers from Google Brain, uses feedforward networks as experts, and linear-softmax gating. Similar to the previously proposed hard MoE, they achieve sparsity by a weighted sum of only the top-k experts, instead of the weighted sum of all of them."
"Top-k experts," in case of some DeepSeek's models k=1.

Only because someone else is paying the bills. I use Claude Opus at work because my employer pays for the tokens and encourages me to do it.
At home, I use DeepSeek Flash. It's not as good, but it's maybe 0.7 quality for 0.001 cost.
GPT refused to do so (citing that it's illegal even though I own the games). Deepseek did a wonderful job for 7 cents.
At work I use Opus because, why not? But I could easily switch to a less capable model if needed.
In the. US at least it is actually illegal to download ISOs/roms of games, even if you own a physical copy. It's a stupid law and as a downloader (as opposed to the people hosting the files) your chances of getting into any kind of actual legal trouble are effectively 0, but it is still against the law.
BTW, I also use DeepSeek v4 Flash very frequently: fast and so cheap it is almost free.
The best answer would be to pull session stats from your harness and compare that against the limits. I think Anthropic publishes the limits of each plan.
If you’re using a pretty stock harness and not doing crazy multi-agent stuff with it, you’re probably fine.
My girlfriend built a whole (but simple) React app with it and only hit the limits of the $20 plan once. In fairness, she was trying to get it to clean up a bunch of 800ish line React files at once with a vague “make it look nice” prompt that she ran a few times. I think it was just churning for like half an hour straight before she burned all her credits.
It’s probably enough if you’re not on a fully agentic development strategy, it’s plenty to have it write tests and do comments and stuff, just not enough to continually have it doing giant refactoring passes.
Cursor's $20 a month plan provides a reasonable amount of Opus tokens as well.
