    This isn't really about cost savings, it's about control. Self-hosting makes sense when you need data privacy, custom fine-tuning, specialized models, or predictable costs at scale. For most use cases requiring GPT-4o-mini quality, you'll pay more for self-hosting until you reach significant volume.

    The "not optimized" self hosted deployment is 3x slower and costs 34x the price using the cheapest GPU / a weak model.

    I don't see the point in self hosting unless you deploy a gpu in your own datacenter where you really have control. But that costs usually more for most use cases.

    How to move from one service that is out of your control to another service that is out of your control.

    To people from Cerebrium: why should I use your services when Runpod is cheaper? I mean, why did you decide to set your prices higher than an established company with significant user base?

    I’m trying to figure out the cost predictability angle here. It seems like they still have a cost per input/output tokens, so how is it any different? Also, do I have to assume one gpu instance will scale automatically as traffic goes up?

    LLM pricing is pretty intense if you’re using anything beyond a 8b model, at least that’s what I’m noticing on OpenRouter. 3-4 calls can approach eating up a $1 with bigger models, and certainly on frontier ones.

    Why? Honestly, there are already tons of Model-as-a-Service (MaaS) platforms out there—big names like AWS Bedrock and Azure AI Foundry, plus a bunch of startups like Groq and fireflies.ai. I’m just not seeing what makes Cerebrium stand out from the crowd.

    Do you forecast costs or just provide more visibility?

    Is this article just saying openai is orders of magnitude cheaper than cerebrium?
