Hacker News, YouTube, Lemmy
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
Researched Oct 7, 2026
Who should pick which
- Systems engineer in aerospacePick: Dalus
Dalus is built for SysML v2 modeling, requirements management, and safety analysis—core tasks in aerospace engineering. Its AI Copilot reduces manual modeling effort, and SOC 2/GDPR compliance satisfies regulatory needs.
- AI safety researcher at a frontier labPick: Surge AI
Surge provides expert red teaming and RLHF tailored for frontier models. Its benchmarks (Riemann-bench, GDP.pdf) expose weaknesses, and the expert workforce ensures high-quality adversarial testing.
- Hardware startup with limited budgetPick: Dalus
Dalus's free tier (250 elements) lets small teams start modeling at no cost. Pricing scales gradually, and AI assistance speeds up system architecture tasks.
- LLM trainer needing fine-tuning dataPick: Surge AI
Surge's domain experts (doctors, lawyers, engineers) generate high-quality RLHF data for complex tasks. The platform's benchmarks help evaluate model performance beyond simple metrics.
- Automotive team adopting SysML v2Pick: Dalus
Dalus is optimized for SysML v2, essential for automotive systems engineering. Integrations with Simulink and Jira fit existing workflows, and version control is coming soon.
Frequently Asked Questions
Can Dalus replace a traditional MBSE tool like Cameo?
Dalus is a modern AI-native alternative, but legacy teams with deep investment in Cameo may find migration challenging. It supports SysML v2 and offers AI Copilot for model generation, but version control is still upcoming.
Does Surge AI provide automated evaluation without humans?
No, Surge's core value is expert human graders. For fully automated benchmarks, other tools may be better. Surge specializes in human-in-the-loop evaluation for nuanced reasoning tasks.
What is the free tier limit for Dalus?
The free tier caps at 250 model elements, suitable for small projects or proof-of-concepts. Larger teams need a paid plan.
How does Surge AI ensure data privacy?
Surge offers custom contracts and can sign NDAs. However, since it relies on human workers, sensitive data should be assessed. Dalus supports SOC 2, GDPR, and GovCloud for regulated data.
Which tool is better for a pure software development team?
Neither is ideal. Dalus is hardware-focused; Surge is for AI training. Software teams may prefer UML tools with GitHub integration.
Can I integrate Surge AI with my existing ML pipeline?
Yes, via Python SDK and REST API. Surge is designed for post-training optimization and RLHF workflows.
Does Dalus support real-time collaboration?
Yes, multiple engineers can work on models simultaneously. Status tracking and real-time updates are core features.
What are the latest benchmarks from Surge AI?
Antidote leaderboard (expert-graded), Riemann-bench (extreme math), GDP.pdf (PDF understanding), ComplexConstraints (entangled instructions), and EnterpriseBench (RL environments).
