Enterprise AI procurement in June 2026 means navigating six frontier vendors, multi-agent orchestration, and strict compliance requirements.
Security & compliance matrix
Claude Fable 5: strongest safety posture, 30-day retention, Covered Model designation. ChatGPT 5.6: mature SOC2, Azure private endpoints. Gemini 3.5: VPC-SC, Google Cloud compliance. GLM 5.2: APAC data residency options.
TCO modeling
Don't compare list prices alone. Factor refusal fallbacks (Fable 5), orchestration overhead (Fugu), and volume discounts. GLM 5.2 and DeepSeek V4 for internal tools; frontier closed models for customer-facing.
Multi-vendor strategy
Standard pattern: primary (Fable 5 or GPT 5.6), secondary (Gemini 3.5), budget tier (DeepSeek V4), orchestration layer (Fugu) for quality-critical batch jobs.
Vendor lock-in mitigation
Abstract via OpenAI-compatible gateways. Sakana Fugu explicitly reduces single-vendor dependency. Maintain prompt versioning across model upgrades.
