Comfy Router is live One API for frontier image, video, 3D, and audio models. Same model string. Same arguments. No new SDK, no new key, no redeploy. What Comfy Router gives you: → Explicit routing. You name the provider, we call that provider. It's down? The request fails there. No silent fallback. → Every job returns the provider that ran it. Log it, bill it, debug it. → Async. submit() returns a request ID immediately. The queue retries 429s and transient errors until a slot opens. subscribe() submits and polls to completion. → Batch-friendly. Queue a few hundred jobs, hold the IDs, pull results as they land. Nothing blocking on a 5-min video render. → 24h retention on inputs and outputs, then deleted. → Comfy credits. No sub, no Router fee. Providers at launch: Comfy. Runware, Wavespeed, Fal, Higgsfield. Multi-provider where the model supports it. Get Your API Key with the link below. ⬇️

Congratulations to @alexatallah, @louis_g_v and the entire @openrouter (F23) team!
We were the first firm to invest in @OpenRouter. When @alexatallah joined @hf0, he had already built a $13B company. He knew what he was doing. He didn't need help. Alex joined HF0 because we're not an incubator. We don't work with founders who need help. HF0 is a family... We live under one roof. We eat around one table. We work tirelessly in pursuit of the singular ideal: That by removing every distraction, and relentless and fearlessly training one's energy on the most important problem in each moment - massive, seemingly impossible feats of entrepreneurship become tractable. OpenRouter's journey embodies the fruition of this philosophy. Just 3 years ago, @alexatallah presented OpenRouter at HF0 demo day. Now, he's here.

.@FishAudio is one of the few legitimate challengers to Eleven Labs. That’s why we were one of their first backers. Don’t think their models are better? Try it for yourself.
Today we’ve raised $52M Seed and we are announcing the public launch of S2.1 Pro. >It can clone a voice from 5 seconds of audio >2x faster than Cartesia & 1/6th the cost of Eleven Labs >most expressive model with word level control over emotion, intonation, pacing etc We support frontier AI companies including HeyGen, LiveKit, Retell, Sanas, and OpenArt all run our model in production. If you're a business and we can't cut your voice AI costs by 50%, we'll give you 1 year of Fish Audio for free. Book a demo: s.fish.audio/tmapke To celebrate our first birthday, we'll give you 1 month of S2.1 Pro for free. Like, retweet, and comment “Fish” to get it.

We drove 410% conversion lift on @Replit's enterprise funnel, 2x-ing the number of demo requests. All in a matter of months. "Coframe makes you feel like you have a team of 100 people. There's nothing on the market like it." ⧉ x ⠕

We started building @HiJenny_ai less than 6 months ago to fix American homeownership. Today, on the country’s 250th anniversary, we’re shipping the first-ever AI Home Manager for homeowners and renters. Jenny itemizes everything in your home via voice, photos, and video so your electronics, art, and valuables are properly documented and insured. She books and manages service calls with plumbers, electricians, HVAC, landscapers, and handymen through an AI voice agent that calls and schedules on your behalf. And when you renovate, Jenny helps you scope the project, pick contractors, and manage the work end-to-end from your phone. Think ServiceTitan‑class orchestration, but for everyone—homeowners, renters, contractors—without the call center. Already 1,000+ homes are managed with HiJenny.

BlockRun has received an investment from the Base Ecosystem Fund by Coinbase Ventures @cbventures. This represents a major milestone in our mission to enable AI agents to pay and get paid in @USDC. We're the No. 1 AI agent payment company by transaction volume. We're deeply grateful for @Base, @x402, and the @CoinbaseDev . Our entire tech stack is built on x402 because of its frictionless design—it's what makes agent payments possible at scale.The journey is just beginning. We're building an entirely new economy for AI agents.

We asked Claude to fix one file. It read 47, including the SSH keys. Spotlight reads your Claude Code + Codex sessions and shows you what actually happened: what to fix, what's burning tokens, what's worth reusing. Free.

Today we’re announcing our $113M Series B led by @CapitalGVC. Over the last 6 months, weekly volume on OpenRouter grew from 5T to 25T tokens as AI rapidly shifts from experimentation into production. We’re excited for what comes next.

ComfyUI (W23) raises at $500M.
We just raised $30M at a $500M valuation, bringing our total funding to $47M. Led by @craft_ventures , with @PaceCap , @chemistry , TruArrow, and others. But before anything else: this belongs to the community. ComfyUI started as one developer and one open-source repo. No roadmap. No company. Just creators who wanted real control over how they built with AI. That community is now: → 4 million users → 60,000+ community-built nodes → 150,000+ daily downloads Every number traces back to people who built in the open, for anyone to use. Here's where the funding goes: → Comfy Cloud: for teams and studios that need security and scale → Collaborative workflows: versioning and iteration built for how studios actually work → A better local experience: more seamless, more stable → Ecosystem reliability: making 60,000+ community nodes more dependable → Day-one model support: every major release, compatible at launch We are not building a walled garden. We are building open infrastructure, built to last. Thank you genuinely, The ComfyUI Team

Recursive self-improving AI is here. I had heard people talking about self-improving AIs at some of the frontier labs but wasn't sure how real it was. One of the neo labs in the current @hf0 batch had a breakthrough and now it’s running in our basement. It’s real.
