OpenAI Agents SDK - Pros & Cons
Pros
- ✓Small, Python-first abstraction layer makes it easier to learn than heavier orchestration frameworks.
- ✓Official OpenAI support and default Responses API integration reduce glue code for OpenAI-based apps.
- ✓Built-in tracing, guardrails, handoffs, sessions, and MCP support cover common production agent needs.
- ✓Sandbox agents are useful for coding, document, and workspace tasks that need files, commands, and resumable state.
- ✓Open source package means teams can inspect the runtime instead of relying only on a hosted black box.
Cons
- ✗It is a developer framework, not a no-code builder; Python experience is required for meaningful use.
- ✗The SDK is free, but real deployments still incur OpenAI API, realtime voice, tool, sandbox, and hosting costs.
- ✗Pricing research needs manual verification because the OpenAI pricing page was JavaScript-gated during this run.
- ✗Teams still need to design permission boundaries, evals, logging, data retention, and human review processes.
- ✗Best experience is likely with OpenAI models, even though third-party model adapters exist.
Agent 365 - Pros & Cons
Pros
- ✓Provides a single registry that catalogs every AI agent running across Copilot Studio, Azure AI Foundry, and third-party platforms in a Microsoft 365 tenant
- ✓Extends existing Microsoft Entra identity, Conditional Access, and Zero Trust policies to AI agents without requiring a separate identity stack
- ✓Native integration with Microsoft Purview means data loss prevention, sensitivity labels, and audit logs already cover agent activity from day one
- ✓Microsoft Defender coverage applies threat detection and response to agent behavior, addressing prompt injection and data exfiltration risks
- ✓Designed for the 400M+ Microsoft 365 commercial seats, so most enterprises can deploy without a net-new vendor procurement cycle
- ✓Backed by Microsoft's enterprise SLA, FedRAMP, and global compliance certifications already in place for the rest of the M365 stack
Cons
- ✗Enterprise-only licensing with no public pricing or self-serve tier — small teams and individual developers cannot evaluate it
- ✗Heavily optimized for Microsoft-built agents; governance depth for non-Microsoft agent frameworks (LangChain, CrewAI, custom Python agents) is more limited at launch
- ✗Requires existing investment in Microsoft Entra, Purview, and Defender to unlock the full governance value — standalone deployment offers diminished benefits
- ✗Newly announced in late 2025, so production references, third-party reviews, and long-term reliability data are still limited
- ✗Adds another administrative surface for IT teams to learn and operate alongside the existing M365 admin centers
