Fable 5.1 实测：用 AI 复刻被 Canva 收购后关停的 remove.bg

73 Share Hey folks,

I said Tuesday I was going on a bit of a tear with building stuff…

I scraped the OpenRouter website to build this, which constantly updates

Ben Tossell @bentossell 53.5 million tokens per second are moving through OpenRouter’s top 20 apps right now.

I scraped their public usage pages to show which models are being used bentossell.com/realtime-tokens 3:02 PM · Sep 1, 2026 · 13.9K Views 10 Replies · 7 Reposts · 64 Likes I also got an email that remove.bg - which removes backgrounds on images - is being shut down in December after being acquired by Canva, so I one-shot my own version with Fable 5.1

so fable made me my own (you can clone it) 3:31 PM · Sep 2, 2026 · 32.7K Views 30 Replies · 5 Reposts · 309 Likes People have pointed out you can do this natively on a Mac (I didn’t actually know that), but so what? remove.bg was a business, it got acquired for money, people use these kinds of things.

I’m not building these for anyone specifically or to make money with them. I just like building. I like new things. I’m doing it because I can. It’s fun. And I learn a lot about how to build by actually doing it.

Building any idea helps you have more ideas.

In tomorrow’s session breakdown, I’ll be going through (at least) one build - where I scraped 105 million rows of public government information to see where they spend our tax money… I used 2 billion tokens 😳.

With all my builds I’ll make them open-source so you can clone/remix them.

This is what my agent usage is like btw:

p.s. I’m out of my Fable weekly usage already 🥹

Anthropic also reduced the cost of caching inputs for Fable by 75%, making API usage about 25% cheaper than before.

OpenAI’s Astra is also coming soon (rumours say today).

Another new model from Meta - Muse Voice transcribe looks really insane for transcription use cases. I wish it were open-source.

Gemini models can now decide which bits of a video are worth watching . Instead of sampling a video at a fixed frame rate, it searches across frames, audio and transcripts for the moments it needs. 88% fewer tokens used, up to 66% cheaper and a minor bump in accuracy on benchmarks.

Inworld built Realtime TTS-2 for the next wave of consumer apps. That takes three things: text-based voice design, sub-100ms latency at P99, and one voice identity across 200+ languages. Learn how to give your AI apps a voice . *

Claude Code/Cowork can now use your computer in the background, while you do your other work, just like Codex. Previously, Claude would take over the computer, making it unusable for you while Claude worked.

WebMCP adds tools (that agents can use) for any action you can take on a website (vs having to use the UI). Vercel’s agent-browser now uses WebMCP if present and then falls back to clicking around on the UI.

Generate up to a minute of 1440p video from 1-6 images, with pixel-perfect camera control.

Bella @nazzari if you are non-technical and your github looks like this I want to be friends and I want to hire you 3:22 PM · Sep 1, 2026 · 159K Views 628 Replies · 18 Reposts · 1.21K Likes Sam Altman @sama Over the summer, we have been sprinting on safety priorities; it's more important than ever for capabilities and safeguards to advance together. We have more to do but have made a lot of progress. We are also going to be launching our next model soon.
