Today, we're releasing our open-weight, auto-routing model @daridotdev, built for coding agents.
We're state-of-the-art on the Pareto Frontier, w/ 70% cost reduction + comparable coding performance to Fable.
Bring your own evals, choose your models, or use our defaults.
Vignesh Varadarajan retweeted
We made deploying agents to prod so easy your coding agent can do it in under 5 minutes.
Get a production-grade API that scales to 100s of concurrent sessions, pauses for days between messages, and recovers sessions even on sandbox crashes or LLM provider failure.

Introducing @daridotdev.
Deploy your AI agent as a stateful, versioned API.
- durable sessions
- built-in execution + sandboxes
- tools, files, retries handled
Stop stitching infra. Just dari deploy.

Back at @ycombinator for alumni demo day and you could feel the difference. Observations as a founder-turned-investor:
1. W26 is shipping way faster than earlier batches. Floored by companies that pivoted in the last few weeks with real products and customers. I attempted a late pivot in the S21 batch and it was… not like that
2. Spending more on tokens than headcount. Many 2-person teams consuming over $75K of tokens / month with no signs of slowing down.
3. First hires are increasingly in sales / commercial engineer roles, not “pure” devs. Distribution > engineering.
4. Crazy traction, and it’s not just "YC ARR”. Founders running sales / success / support agents are showing up to enterprise conversations looking like mature orgs. Lots of healthcare, banking, govt logos across the batch.
5. Valuations reflect all of this. Most teams raising at $30-40M vs ~$20M just a year or two ago. Love seeing founders get rewarded for speed, progress, profitability.
6. And a fun surprise: tons of deeptech love! Robotics, energy, drug discovery - YC branching out in a positive way.
Most importantly: founders still love YC. Reuniting with my batchmates (five years later!) and supporting W26 founders means more than I can put into a tweet.

Vogent launched Voice Agent Wizard - it builds complete voice AI agents from a simple text description in minutes instead of weeks.
building a working voice agent today means 3-4 weeks of development, tweaking parameters, and debugging why it breaks with real users.
The wizard is trained on thousands of actual agent designs. You describe what you want, upload a few conversation examples, and it generates everything - architecture, prompts, edge case handling.
More details 1/2

.@vogentai just released Vogent-Turn-80M: an open-source, state-of-the-art turn-detection model for voice AI.
It improves any voice AI stack by detecting when to wait and when to speak, reducing interruptions and making conversations more humanlike.

The Vogent AI team nailed this one 🔥🔥 They rearchitected the sesame CSM 1B model for:
- Ultra-realistic streaming voice
- Latency < 200ms
- Easy voice cloning (example Trump)
Listen to the AI Trump tariffs conversation but wait till you hear the next one.

Excited to share our deployment of Sesame voices - use them for no additional cost!
We rebuilt @sesame's CSM-1B to make the most realistic voice agents you’ve ever seen.

You can now use @OpenAI GPT-4o STT and voices on Vogent! This lets you control voice attributes with natural language; here we use it to make a collections agent more effective. (sound on)
