| Compare | Fireworks AI | OpenAI |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | Engineering teams running open models | Developers building AI-powered features |
| Who it's not for | Devs who just want a one-line GPT API call | Small teams needing predictable monthly costs |
| Privacy | Trust center with SOC 2 and triple ISO certification; zero data retention options; no Fireworks-attributed CVEs in sources reviewed.10 | Active CVE program, but 2026 brought a publicized agent escape and Codex vulnerabilities. |
| Support quality | No direct support evidence found | Billing dispute threads suggest weak support |
| Public sentiment | Coverage is sparse and mixed: technical users credit speed and model selection, but Trustpilot sits at 2.3/5 and pricing draws the loudest complaints.¹ | Reviewers credit OpenAI with model quality and market leadership while Reddit threads flag billing disputes and security incidents.15 |
| Biggest gotcha | Per-token pricing across serverless and on-demand complicates cost forecasting; pricing is G2 users' top complaint.¹ | 2026 agent escape incident: run vendor security review before enterprise deployment |
