Which platform should you choose?
Access, host, and serve models for text, image, audio, and agent applications. Start with a real task and compare the output, effort, permissions, and full cost. Compare latency, usage billing, rate limits, model licenses, and data handling for your workload. Validate claims with the vendor and test the important workflow with your team. Differences shown here are evaluation prompts, not hands-on performance findings.
