Reliable agents are built in layers: trustworthy data, caller verification, scoped tool permissions, and human handoff when the model gets it wrong.
At VapiCon, the people building those layers and the people running agents on them break it down.

Releasing the model weights and technical report of Kimi K3.
Kimi K3 is our most capable model: a 2.8T MoE model with native visual understanding and a 1M-token context window.
New model architecture: 2.5x the intelligence per unit of compute, not just more params.
Alongside Kimi K3, we're opening up more of the stack behind it — high-performance attention kernels, MoE communication library, and infrastructure for running agent environments at scale.

At its peak, Sun Microsystems was valued at 205B (394B if inflation adjusted). Sold software in enterprise servers. Got disrupted by Linux, x86, and commodity hardware. Ended up selling to Oracle for 7.4B, losing 96% of its value.
Open source models running on local hardware can have a similar impact given what’s going on.

Keeping up with AI news is becoming a full-time job.
So my friend @ivan_bezdomny built HuggingNews, an AI-curated feed that surfaces the news actually worth reading. Soon, it will even personalize the feed using your Hugging Face profile. Been using it for weeks!
Bookmark it, or ask your agent to send you the top 10 stories every morning or night. Less noise. More signal. More building!

Your B2B website is the worst salesperson on your team🚨
It works one shift. Says the same thing to every visitor. Give up the second they scroll. Meanwhile, you're paying $40 CPMs to send traffic to a brochure.
@interact_ai is rebuilding the interface. An AI agent lives on your site and turns every visit into a personalized walkthrough of your product:
▫️ Starts a real conversation the second a visitor lands
▫️ Generates slides, sections, and docs on the fly based on intent
▫️ Walks each visitor through a tailored demo
▫️ Books meetings inline, no forms, no friction
▫️ Logs every conversation so your AE walks into the call already briefed
@sprintoHQ , @LightBeamAI and many others have deployed it and already seeing 3.2x conversion in 2 months and still increasing.
Would you add it to your website tomorrow?

Sometimes the best marketing ideas show up outside of meetings and slides, over a drink with the right people around.
We’re hosting an end-of-year marketers hangout in San Francisco to bring together folks building and marketing great products. It’s a space to share real stories from the year, what worked, what didn’t, and what’s top of mind as we plan for what’s next.
Expect thoughtful conversations, a relaxed atmosphere, and good company.
🗓 Tuesday, Dec 30
⏰ 4:00 PM to 8:00 PM
📍 Standard Deviant Brewing, Pier 70, SanFrancisco

Math.
Prime numbers feel like the universe whispering that it still keeps some secrets just for itself.

Kalpa Labs (@KalpaLabsAI) is training one generalist model for all speech tasks. Steer it like an LLM, give long system prompts & make use of native contextual awareness.
Congrats on the launch, @pshishodiaa and @jhagauti!

When you're fetching data with RAG for voice assistants, you should give feedback to the user so that they know they might need to wait a couple of seconds before the result comes back. Thankfully, @livekit agents make this super easy.
I'll show 4 different ways w/ code 🐍
