@JasonKuperberg and I are looking to back something here as well… and hopefully blow them up on X. Would love to partner on finding the right one!

Groq’s Real Value: Token Throughput Over Inference Speed
By
–
IMO this is the big opportunity for Groq, and one of the main reasons I invested. Faster inference is cool, but the real value is going to be in doing more tokens per prompt.

RAG vs Fine-tuning: Information vs Behavior Model Adaptation
By
–
@corbtt @dvdcrbt can give concrete examples, but from my experience, they enable completely different things. RAG/search really just gives the model *info* to work with. Fine-tuning changes the *behavior* of the model.

By
–
If you're a developer, here's what you need to know about the new @OpenAI open source models: – They come in two sizes (20B + 120B)… both are impressive, but I'll be focusing mostly on the 120B for the rest of this post – Capabilities (at a glance) are essentially o3 level…
