Choose DeepSeek-V3 when
Depends on provider path and compliance review—treat as a diversification bet.
Choose GPT-4o when
Strong when Azure AD, private endpoints, and Microsoft procurement are standard.
Overview
DeepSeek-V3 and GPT-4o overlap on coding and reasoning workloads but differ in ecosystem, multimodal breadth, and how teams buy and route traffic (OpenAI/Azure vs DeepSeek’s API paths). Choose based on evals, compliance, and integration cost—not hype.
Recommendation
Run a two-week A/B on real traffic with guardrails. If DeepSeek wins on cost-quality and passes security review, route non-critical workloads first; keep GPT-4o where integrations and multimodal paths are critical.
Limitations and trade-offs
Regional availability, policy constraints, and feature parity change frequently. Multimodal and audio behaviors differ—validate against your exact SDK path.
