Thanks for having us. @CompleteSkeptic’s pink personality and great energy really lit up the room.

If you are interested to hear a more grounded and first principled way of thinking about AI, please check out the video when it comes out.

Also please DM me if you are an energy drinks company. We are powered by energy drinks. 🫣❤️😅

We need more evals for document understanding. ParseBench is a really great start. I respect @llama_index ‘s work on this. 📈

[Jerry Liu @jerryjliu0]

We benchmarked GPT-5.5 on document understanding 📄📊

We ran it through ParseBench, our comprehensive OCR benchmark over enterprise documents. We evaluated metrics across various dimensions: visual grounding, tables, charts, and more.

We evaluated GPT-5.5 on mid thinking and zero-thinking modes. When compared against GPT-5.4 (0 thinking) and Opus 4.7 (adaptive thinking):
📈 GPT-5.5 wins on tables
📈 GPT-5.5 wins on visual grounding
📉 GPT-5.5 0-thinking does worse on charts than GPT-5.4 0-thinking
📉 Higher thinking does worse than lower thinking of content faithfulness, semantic formatting
📉 Opus 4.7 wins overall on content faithfulness and semantic formatting
💸 GPT-5.5 is expensive: 13c per page at mid-thinking modes and 5.93 at 0-thinking! This is 5x the cost of any competitive OCR solution.

Conclusion: GPT-5.5 is one of the better frontier models out there in terms of pure accuracy, but def not pound for pound w.r.t price.

Woohoo congrats @yoland_yan

[ComfyUI @ComfyUI]

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
