## Frequently Asked Questions

### Which AI agent platform is best in 2026?

LangChain maintains #1 position with 48% market share (up from 42%), but CrewAI is the fastest-growing platform at 67% quarterly growth, capturing enterprise multi-agent orchestration.

### What new platforms emerged since v1.0?

Key new entrants include Letta (MemGPT) for long-term memory agents, Phidata for production-grade agents, and OpenAI's Assistants API v2 with improved tool use and file handling.

### Should I migrate from my current platform?

Migration is recommended if your current platform lacks production monitoring (LangSmith equivalent), has limited model support, or doesn't support multi-agent orchestration for complex workflows.

### How do platform costs compare?

Open-source platforms (LangChain, CrewAI) have zero licensing costs but require engineering investment. Managed platforms (Vertex AI, Azure AI) cost $5K-$25K/month but reduce DevOps overhead.

### What are the key technical improvements since v1.0?

Major improvements: LangGraph for stateful workflows, CrewAI 1.0 with hierarchical agent management, tool-use improvements across all platforms, and 3x better token efficiency.
