Thunder Compute (YC S24)
Discussed by users across 1 sources · 55% positive — mixed (weighted across 1 source)
Hacker News
What users praise
- • Genuinely aggressive GPU pricing — RTX A6000 at $0.35/hr, A100 80GB at $1.09/hr
- • Per-second billing on sandboxes with scale-to-zero suits RL rollouts and CI evals
- • Neither instances nor sandboxes are ever preempted, unlike spot-priced competitors
- • Zero egress fees removes a classic cloud surprise on data-heavy ML workloads
What frustrates them
- • No regional spread — a single footprint constrains latency and data-residency needs
- • Self-serve tops out at 8 GPUs; larger runs require a manual conversation
- • Sandbox access is request-gated rather than self-serve by credit card
- • Zero independent reviews means uptime and support claims are unverified publicly

55 mentions across 5 sources · 53% positive — mixed (weighted across 5 sources)
Hacker News, App Store, Stack Overflow, GitHub, Lemmy
What users praise
- • Produces embeddings good enough that developers ship real RAG, search, and memory apps on it
- • Domain-tuned legal and code models address the retrieval problems generic embedders struggle with
- • Shorter vectors (3x-8x) cut vectorDB storage and search spend meaningfully in production
- • Plugs into any vectorDB and any LLM, confirmed by builders wiring it into Qdrant and GoodMem
What frustrates them
- • Default training on API customer data is a serious blocker for confidential workloads
- • Lost a head-to-head embedding comparison to a smaller Jina model in one benchmark
- • Python library has only ~114 GitHub stars, so community help and examples are limited
- • Per-token billing with no subscription makes agent-driven spend hard to cap

Who should pick Thunder Compute (YC S24), and who should pick Voyage AI?
- Enterprise RAG developer (finance)Pick: Voyage AI
Voyage AI offers domain-specific embedding models for finance, long-context support up to 32K tokens, and SOC 2/HIPAA compliance, essential for regulated document retrieval.
- Data scientist training LLMs on a budgetPick: Thunder Compute (YC S24)
Thunder Compute provides cheap on-demand GPUs with per-minute billing, fast provisioning, and VSCode integration, perfect for cost-sensitive training workloads.
- Legal tech startup building RAGPick: Voyage AI
Voyage's legal-specific embedding models and rerankers with instruction following improve accuracy in legal document retrieval, reducing hallucination risk.
- AI researcher with bursty batch jobsPick: Thunder Compute (YC S24)
Per-minute billing and no minimum commitment allow researchers to spin up A100s for short experiments without paying for idle time.
- Developer needing multimodal retrievalPick: Voyage AI
Voyage announced voyage-multimodal-3.5, which will handle multimodal data (text+images) in retrieval, a feature Thunder Compute does not address.
Frequently Asked Questions
Are Voyage AI and Thunder Compute direct competitors?
No. Voyage AI provides domain-specialized embedding and reranking models; Thunder Compute offers on-demand GPU cloud infrastructure. They serve different layers of the AI stack.
Which is better for a startup with limited budget?
Thunder Compute for GPU compute (per-minute billing, no commitment). Voyage AI requires contacting sales, but its low-dimensional embeddings can reduce downstream vector DB costs.
Does Thunder Compute offer any AI models?
No. Thunder Compute is raw GPU compute; you bring your own models and code. Voyage AI provides pretrained embedding and reranker models.
Can I use Voyage AI with Thunder Compute GPUs?
Yes. Voyage's embedding models can be accessed via API and used with any compute backend, including Thunder Compute for inference or fine-tuning.
Does Voyage AI support multimodal retrieval?
Yes, with the announced voyage-multimodal-3.5 model. Current models are text-only (including code and long-context).
What GPUs are available on Thunder Compute?
NVIDIA A6000, L40, A100 80GB, and H100 PCIe, in configurations from 1 to 8 GPUs.
Does Voyage AI have a free tier?
No. Pricing is contact-based; no free tier is mentioned.
How does Thunder Compute achieve its low pricing?
Through proprietary GPU virtualization (GPU-over-TCP) that improves fleet utilization, reducing waste and passing savings to customers.
