Has anyone used Helicone with Azure OpenAI? Any gotchas?

Hey everyone! I've been lurking for a bit and finally have a reason to post. I'm super new to the whole LLM observability space, but my team is starting to use Azure OpenAI for a few internal automation projects. I've been reading all the great stuff about Helicone here on the forums, and it seems like a perfect fit for what we need—mainly tracking costs, latency, and usage across different projects and team members. My question is pretty specific: has anyone here actually set up Helicone to work with Azure OpenAI's endpoints? I know the docs say it's supported, but I'm always a bit nervous when connecting services like this. I'm wondering about the real-world, practical gotchas. Like, for example, does the configuration differ a lot from the standard OpenAI setup? I saw you need to use a custom base URL, but are there any header quirks or authentication nuances with Azure's API keys versus OpenAI's? Also, how well does Helicone handle Azure's unique features, like different deployment names for the same model? I'm picturing a scenario where we have a `gpt-4` deployment in Azure that's actually named something like `mycompany-gpt4-deploy-001`—does all the cost tracking and model attribution in Helicone still work smoothly? And maybe most importantly, from a project management perspective, did you run into any issues with rate limiting or increased latency by adding Helicone as a proxy? Our use cases aren't crazy high volume yet, but we need things to remain pretty snappy for user-facing tools. Really appreciate any insights you all might have! I'm trying to build a case for using Helicone to bring some visibility into our scattered experiments, and hearing about your direct experience would be a huge help in avoiding any trip-ups during the rollout.

You're spot on about the coordination overhead. That 12% failure rate over time is a great data point - it's the kind of leaky abstraction that kills adoption because the dashboard becomes "that unreliable cost thing" teams stop trusting.

I've found the explicit headers, while manual, actually help with adoption in a different way. When a team has to consciously tag their calls, it triggers a conversation about *why* we're tracking costs in the first place. It moves the proxy from being invisible infra to a governance tool they have a relationship with. Annoying? Yes. But sometimes the friction is the point.
