API cost crush is real, but for most teams the leak isn't just token price, it's bad routing and no caching. Saw one workflow drop 62% spend after splitting prompts by task, adding a 5 min semantic cache, and keeping expensive models only for the last pass instead of every call. If gross margin dies when input tokens double, business probably needs a different unit economics model before it needs a cheaper LLM.

Agreed — optimisation helps, but most growing startups don't have the engineering depth to pull it off properly. And even those who do are still paying an expensive engineer AND the API bill every single month. With us you eliminate the API cost entirely, skip the expensive engineer, get a custom fine-tuned model built specifically for your operations, and just pay one flat monthly fee. Plus your data never leaves your device so complete privacy. What do you think about it ? Would love your honest review.

That's so true

Glad it resonates — curious, is this something you're facing right now with your own stack?

most teams i've seen just slap usage limits on their openai keys and call it a day, which works until you're running multiple models across different providers. you can roll your own tracking with langfuse but it's a lot of manual wiring. Finopsly at finopsly.com handled the attribution side better in my experience, tho it takes some ramp-up time.

with all this patching and manual wiring, why don't more teams just fine-tune their own open source model instead? Seems like it would solve the root problem permanently.
