Which platform won't get me fired?

Azure OpenAI. It's the safe choice that works out of the box. When it inevitably has issues (and it will), you can blame Microsoft, not your architecture decisions. Plus, your IT team already knows how to navigate Microsoft support hell.

Can I just use multiple platforms and route between them?

Sure, if you want to spend 6 months building routing infrastructure and debugging why Platform A is down while Platform B is rate-limiting you. I've done this - it's probably not worth it unless you're at massive scale (like 100M+ requests/month). For most companies, pick one and stick with it. But maybe I'm just bitter about the experience.

What about vendor lock-in?

Every platform locks you in somehow. AWS locks you into their ecosystem, Microsoft locks you into Office integration, Google locks you into their ML toolchain, and Claude locks you into building your own everything. The trick is picking the lock-in that aligns with your existing investments.

Is Claude really that much better at coding?

Yes, and it's not even close. Claude 3.5 Sonnet understands code context way better than GPT-4o, generates fewer bugs, and actually follows architecture patterns. But you'll spend months building the infrastructure that Azure OpenAI gives you for free. Only worth it if code generation is your primary use case. At least in my experience.

Why are cloud AI platforms so expensive compared to direct APIs?

Because they're not just selling you API access - they're selling you infrastructure you don't have to build. Azure OpenAI costs 3x Claude direct API, but includes SSO, monitoring, scaling, compliance, and support. If you value your engineers' time, it's often cheaper.

What's this 'intelligent routing' marketing stuff about?

AWS's way of saying "we'll use the cheapest model that doesn't completely suck for your request." It works, but the savings aren't as dramatic as they claim. We saw maybe 15% cost reduction, not the 30% they advertise. Still useful though. Your results might be different.

Will AI prices keep dropping?

Compute costs are dropping, but these platforms are adding enterprise features faster than costs decrease. Expect prices to stay roughly flat while you get better models and more features. Don't bank on AI getting dramatically cheaper.

Which platform actually scales the best?

Google Vertex AI handles the highest throughput, but good luck configuring it. AWS Bedrock scales automatically but throttles aggressively. Azure OpenAI scales predictably within Microsoft's infrastructure limits. Claude Direct scales as well as your infrastructure team can build it. Honestly, they all have different scaling problems.

What about latency for real-time applications?

If you need under 200ms consistently, you're probably using the wrong technology. All these platforms add network overhead. For truly real-time stuff, consider smaller models running on your own infrastructure. But for most "real-time" business applications, 300-500ms is fine. I think.

Can I fine-tune models for my specific use case?

- Google Vertex AI: Comprehensive fine-tuning, but requires ML expertise - AWS Bedrock: Limited fine-tuning through SageMaker, pain in the ass - Azure OpenAI: OpenAI's fine-tuning, decent but not amazing - Claude Direct: No fine-tuning, prompt engineering only Honestly? Most companies think they need fine-tuning but don't. Try prompt engineering first. Could be wrong about this, but that's been my experience.

Which platform is best for healthcare/finance/government?

AWS Bedrock for government (FedRAMP), any of them for healthcare (all have HIPAA), Azure OpenAI for finance (Microsoft already has the certifications). But the real answer is: hire a compliance lawyer, don't trust random engineers (including me) on the internet.

Where does my data actually go?

- AWS Bedrock: Stays in AWS, never leaves your VPC if configured right - Azure OpenAI: Microsoft processes it, but they're contractually bound not to use it - Google Vertex AI: Google processes it, similar contractual protections - Claude Direct: Anthropic processes it, good privacy practices but you have less control

What happens if there's a data breach?

You're probably screwed regardless of platform. The bigger risk is usually your own application security, not the AI provider. Focus on securing your API keys and user data, not worrying about theoretical breaches at trillion-dollar companies.

What breaks in production that you don't expect?

Rate limiting hits differently under load, models occasionally return garbage output, and billing spikes happen when you least expect them. Always build retry logic, output validation, and cost alerts from day one.

Which platform has the least bullshit support?

AWS support is expensive but competent. Microsoft support exists and eventually helps. Google support is hit-or-miss but their engineers are smart when you can reach them. Anthropic support is responsive but small team. None of them are perfect, honestly.

Should I build or buy AI infrastructure?

Unless you're a tech company with full-time ML engineers, buy it. I've seen too many companies waste 18 months building infrastructure that AWS provides in a weekend. Your time is worth more than the premium you pay for managed services.

After all this pain, which platform would you actually recommend?

Depends what kind of pain you want to deal with. If you want the easiest path and don't mind vendor lock-in, go with Azure OpenAI - it just works. If you need the best models and have engineers who can handle infrastructure, Claude Direct is worth the effort. If you're already on AWS and want cost optimization, Bedrock makes sense. If you have serious ML needs and engineers who don't mind complexity, Google Vertex AI is powerful. The real answer? Pick the platform that aligns with your existing infrastructure and team skills. The worst platform for your specific situation will cause more problems than the "best" platform that doesn't fit your context. I've learned this lesson the hard way - three times.
