Which platform should you choose?
Build agents with code, orchestration, memory, and evaluation libraries. Start with a real task and compare the output, effort, permissions, and full cost. Check licensing, maintenance status, supported providers, and hosting or inference costs. Validate claims with the vendor and test the important workflow with your team. Differences shown here are evaluation prompts, not hands-on performance findings.
