Enterprise Companies
100+ EmployeesThe strongest fit: 24/7 support with SLAs, premium support, AI advisors, Scale Tier uptime guarantees and data residency in ten regions.

OpenAI’s Pros & Cons
Balanced evaluation to help you make an informed decision
Strengths
- Enterprise plans include 24/7 priority support with SLAs
- Premium support adds faster responses, a dedicated contact and on-call availability
- AI advisors help eligible enterprises with organization-wide rollouts
- Scale Tier offers a 99.9% uptime SLA with reserved throughput

- Hosted web search, file search and code interpreter in the same API
- Help center chat is available in most languages
Limitations
- Self-serve API and ChatGPT users reach a chatbot first, with no SLA
- Trustpilot reviews average 1.3, citing hard-to-reach human support and billing disputes
- Prompts over 272K input tokens are billed at higher rates for the whole request

- Fast and Ultrafast modes cost 2x to 6x standard rates
- G2 reviewers report inaccurate answers and usage limits
Our Verdict
OpenAI earns its Best in Support placement for LLM platforms and APIs through the support structure around its models. Enterprise customers get 24/7 priority support backed by SLAs, can add premium support with a dedicated contact and on-call availability, and may qualify for AI advisors on large rollouts. Scale Tier adds a 99.9% uptime SLA with reserved throughput, and the help center chat runs in most languages. Capterra reviewers rate ChatGPT’s customer support 4.0 out of 5. The placement comes with a clear caveat. The strongest support sits behind Enterprise contracts, and self-serve API and Business customers start with a chatbot and have no response-time guarantee. Trustpilot rates OpenAI 1.3 out of 5 across 1,250 reviews, mostly over hard-to-reach support and billing. For companies that will sign an Enterprise or Scale Tier agreement, OpenAI is a well-supported choice; small teams on pay-as-you-go should expect a self-serve experience.
