What users praise
- • Credentialed workforce of doctors, lawyers and engineers instead of generic crowd annotators
- • GDP.pdf cited by OpenAI in the GPT-5.6 release with a concrete 30.7% flagship score
- • Kimi K2.7 post-training run published measurable SWE-Marathon, DeepSWE and Terminal-Bench gains
- • Benchmark catalog spans chart reasoning, dependent constraints, long-context policy and verticals
What frustrates them
- • Contact-only pricing means no public rate card, no tiers, and no way to self-serve
- • Benchmark sponsorship and independence questions raised directly in HN threads
- • Expert-credential verification process is never explained in any community source
- • No community data on support responsiveness, uptime, or SLAs at enterprise scale

Frequently Asked Questions
Can I use Surge AI for simple sentiment classification?
No, Surge is optimized for complex, reasoning-intensive tasks like RLHF, red teaming, and expert benchmarks, not binary labeling.
Does Frizzle require students to type answers?
No, Frizzle is built for paper worksheets—students write by hand and teachers snap photos with a phone, document camera, or scanner.
What subjects does Frizzle support?
Currently only K-12 math. Handwriting recognition and misconception detection are math-specific.
How does Surge AI ensure feedback quality?
It uses a curated workforce of domain experts (doctors, lawyers, engineers) and proprietary benchmarks like Antidote for expert grading.
What integrations does Frizzle have?
Google Classroom, Canvas, Clever, ClassLink. It is FERPA, COPPA, and SOC 2 Type II compliant.
Does Surge AI offer a free trial?
Pricing is contact-based; likely no free self-serve trial. Typically enterprise engagements start with a pilot.
Can Frizzle identify specific misconceptions?
Yes, it has 147 named misconceptions (e.g., misapplying distributive property) and traces prerequisite gaps across grade levels.
Which tool is better for automated grading without humans?
Frizzle, as it uses AI only. Surge AI relies on expert human graders—though can complement automated grading.
