Surge AI
48 mentions across 3 sources · 53% positive — mixed (weighted across 3 sources)
Hacker News, YouTube, Lemmy
What users praise
- • Credentialed expert workforce covers doctors, lawyers, and engineers for reasoning-heavy labeling
- • Benchmarks like GDP.pdf have been cited directly in OpenAI's GPT-5.6 launch materials
- • HANDBOOK.md evaluates long-context agentic policy adherence across Finance and Medical domains
- • ComplexConstraints lifted MultiChallenge by 10.1 when used for 4B model training
What frustrates them
- • Benchmark sponsorship is questioned publicly, undermining independence claims for regulated filings
- • Contact-only pricing forces a sales cycle before any comparison against Scale AI
- • Serves OpenAI, Anthropic, and Meta simultaneously, raising impartiality and leakage concerns
- • Scaling a genuine expert workforce is slow and caps throughput for large programs
