📢 Announcing the new SOTA voyage-3-large embedding model! • 9.74% over OpenAI and +20.71% over Cohere • flexible dim. (256-2048) and quantizations (float, int8, binary) • 8.56% over OpenAI with 1/24x storage cost • 1.16% over OpenAI with 1/192x storage cost ($10K → $52)

Proud to share our best model yet, pushing boundaries again and outperforming all models on all domains (except voyage-code-3 on code). Our binary, 1024-dim embeddings are 5.53% better than OpenA, float, 3072 dim. If you spent $10k monthly on storage, now it’s $104 with us!

Thanks so much for the report Jonathan Ellis. We are serious about evaluation and try hard to provide the best quality for REAL-WORLD use cases.

RL + CoT works great for DeepSeek-R1 & o1, but:  1️⃣ Linear-in-log scaling in train & test-time compute 2️⃣ Likely bounded by difficulty of training problems Meet STP—a self-play algorithm that conjectures & proves indefinitely, scaling better! 🧠⚡🧵🧵 arxiv.org/abs/2502.00212

It's tough when one brain has to handle two "PR"s 😇😇—public relations and pull requests. I felt that I am running MoE— every time I see PR, my visual cortex do a quick routing to the right part of brain.

1/ Congrats Dev Ittycheria Tengyu Ma sahirazam + the Voyage AI by MongoDB team on their acquisition by MongoDB today! As a founding investor, Conviction believed that better embedding and re-ranking models were critical to robust AI-powered search/retrieval (a key enterprise AI use case)

📢 Meet voyage-3.5 and voyage-3.5-lite! • flexible dim. and quantizations • voyage-3.5 & 3.5-lite (int8, 2048 dim.) are 8% & 6% more accurate than OpenAI-v3-large, and 2.2x & 6.5x cheaper, resp. Also 83% less vectorDB cost! • 3.5-lite ~ Cohere-v4 in quality, but 83% cheaper.
