TheFastest.ai
19 mentions across 2 sources · 100% positive (averaged across 1 source)
YouTube, Bluesky
What users praise
- • Daily-updated benchmarks keep data current.
- • Open-source code and public raw data ensure transparency.
- • Standardized methodology (1000/20 tokens) enables fair comparisons.
- • Multi-region testing (US West, US East, Europe) reveals geographic variance.
What frustrates them
- • Only measures speed; ignores model quality, cost, and accuracy.
- • Supports only three US/EU regions – not truly global.
- • No community feedback or reviews to validate trust.
- • Tests only up to 20 output tokens – unrealistic for long responses.

Voyage AI
64 mentions across 6 sources · 45% positive — mixed (weighted across 6 sources)
Hacker News, YouTube, App Store, Stack Overflow, GitHub, Lemmy
What users praise
- • Domain-tuned embedders for finance, legal, and code deliver measurable retrieval precision gains
- • Harvey case study showed 25% fewer irrelevant documents and 3x lower vectorDB costs
- • Low-dimensional embeddings (3x-8x shorter vectors) cut storage and search costs materially
- • Instruction-following rerank-2.5 and rerank-2.5-lite let you steer ranking behavior in plain language
What frustrates them
- • Terms grant Voyage an irrevocable license to train on API customer data by default
- • Usage-based pricing at $0.12-$0.18 per million tokens can balloon for high-frequency agents
- • A community benchmarker found a small Jina model outperformed Voyage for their use case
- • Circular import bug in voyageai v0.3.5 broke lazy import systems before being fixed

Frequently Asked Questions
Can I use TheFastest.ai for production embedding?
No, TheFastest.ai benchmarks LLM inference speed, not embeddings. For embeddings, use Voyage AI.
Does Voyage AI offer a free trial?
Pricing is contact-based, but likely involves a paid plan. No public free tier mentioned.
Which tool provides multimodal embeddings?
Voyage AI announced voyage-multimodal-3.5 for multimodal retrieval. TheFastest.ai benchmarks multimodal prompt latency, not embedding.
Are Voyage AI's models open-source?
No, they are proprietary. TheFastest.ai's code is open-source.
How does TheFastest.ai measure speed?
It uses 1000 input tokens, 20 output tokens, warms up connections, and takes best of 3 runs across multiple regions.
Which tool has longer context support?
Voyage AI supports up to 32K tokens in embeddings. TheFastest.ai does not offer models, only benchmarks.
Can I self-host Voyage AI?
No, it's a cloud API. TheFastest.ai's tools are available for self-hosted benchmarks via GitHub.
Are both tools SOC 2 compliant?
Only Voyage AI offers SOC 2 and HIPAA compliance. TheFastest.ai is a benchmarking site without compliance certifications.
