Developer Portals / API Management
The pivotal question between Cerebras and Azure OpenAI Service is how much of your setup stays portable: Cerebras carries low lock-in and Azure OpenAI Service carries medium lock-in. Cerebras is hosted inference on Cerebras hardware for very fast LLM token throughput. Azure OpenAI Service is Azure-hosted OpenAI models with enterprise compliance and regional endpoints. Pick Cerebras when the job is api gateway and rate limiting and you accept low lock-in; pick Azure OpenAI Service when it is api gateway and rate limiting and you accept medium lock-in. The data we have shows Cerebras at mostly transparent pricing and docs with solid developer experience, and Azure OpenAI Service at mostly transparent pricing and docs with solid developer experience. The honest trade-off: neither is universal — Cerebras is a poor fit for internal, simple projects, and Azure OpenAI Service is a poor fit for internal, simple projects. Match the pricing model and lock-in level to how your team actually works, not the feature list.
Quick take
Cerebras is for hosted inference on Cerebras hardware; Azure OpenAI Service is for Azure-hosted OpenAI models; decide based on how portable the setup must stay.

Choose Cerebras if a free tier with paid upgrade from $50/month is the right shape and the work maps to hosted inference on Cerebras hardware for very fast LLM token throughput.
Not for: Internal, Simple projects
Choose Azure OpenAI Service if some ecosystem coupling is acceptable and the work lines up with Azure-hosted OpenAI models with enterprise compliance and regional endpoints.

Cerebras starts at $50/month on a freemium model; Azure OpenAI Service starts at $1 on a subscription model. That makes the sticker comparison depend on usage — a low entry price can get expensive once volume ramps, so price at your actual workload.
Migration is possible in either direction. Cerebras carries low lock-in and Azure OpenAI Service carries medium lock-in, so plan for meaningful but not blocking rework. Run both in parallel before you fully cut over.
Both Cerebras and Azure OpenAI Service rate the same on developer experience (4/5). The decision on DX then comes down to taste — which CLI, UI, or workflow matches your team's habits. A short side-by-side trial is the quickest way to tell.
Yes — Azure OpenAI Service is a reasonable alternative to Cerebras for api gateway and rate limiting. The practical differences are freemium-vs-subscription billing and low-vs-medium lock-in. If those fit your constraints better, treat Azure OpenAI Service as a credible swap.
