Looking at all these releases it’s not a surprise that model routing is the fastest growing segment in AI right now. There are 10+ LLM companies, each with dozens of models of different modalities, each model with multiple size variants, then different “thinking” levels, then agentic modes, “pro” modes, a “fast” option, standard vs flex vs batch execution. And of course each end combination has a different input/outp…

Who are the customers though? Honest question, I'd like to understand it. For me, anything other than current best available SOTA for any task is unacceptable. The only routing rule I need is "the most powerful model I still have flat-priced quota available for". I mean, why settle for less?

That's nice and all, as long as flat-priced quota continues to exist. Seems unlikely to go on forever!

Go read the safeguards section in the report and you will realize why that is. These models are heavily as safeguarded and that was the initial reason why they said they couldn't and haven't released Mythos because that model is the one without the safeguards. OpenAI is did the same thing when they announced a model without safeguards broken into HuggingFace servers.

Yes, this makes a lot of sense, but it’s just very amusing to see. 2 months ago, the world was about to end, now not so much.

> now not so much

OpenAI Huggingface breach begs to differ

Very interesting that Fable took more creative liberties. Have you tried giving Fable the same task, but also specifying that it implement a pixel-perfect design? I think that I prefer the Fable implementation. I find the UI elements in the Fable implementation to have more contrast, which feels more usable to me. I also like how the right padding on the "Book Your Escape" CTA in the upper right matches the top and b…

All of these are using a build skill which specifies rules for building it, requirements to create a pixel perfect implementation, and tooling to help in that process. Here's the build skill / instructions I pasted in to both of them: > Create a web page implementation from the following instructions: > https://diffui.ai/build/Spa_Booking_Experience_build.md?auth...

Thank you for sharing this. I was just using OpenAI's Product Design plugin[1] to create designs but it just didn't reproduce it in code faithfully so will need to try this.

Looking at intelligence vs cost: - Opus 5 is 10% smarter than Grok 4.5 for 10x the cost. - Opus 5 is a bit smarter than Gpt 5.6 Sol for 2.75x the cost ref: https://artificialanalysis.ai/?cost=intelligence-vs-cost-per...

That's not how intelligence works - "IQ 130 is just 7% smarter than IQ 120"

And to the guardrails of Fable: https://x.com/cheatyyyy/status/2080693704290140330

That tweet says: > Opus 5 can silently fallback to Opus 4.8 (without any notice) on the serverside if you hit a guardrail But https://support.claude.com/en/articles/16049681-why-claude-s... says (emphasis mine): > These checks cause Claude to _visibly_ fallback from Opus 5 to Opus 4.8 [...] You'll see a notice explaining that the model switched, and the response will be labeled with the model that answered. So who is…

Is some random guy on Twitter right, or official support docs that explicitly describe this scenario?

Fable is better than Opus which is better than Sonnet which is better than Haiku. They’re basically just sizes. Though it gets even more confusing because they also have effort levels so it’s not really possible to call one fast and one slow since Fable on Medium will be faster than Opus on Max. I agree it’s confusing, and now OpenAI is following Anthropic’s lead with their new naming (Sol, Terra, Luna).

But according to their benchmarks Opus 5 outscores Fable 5 on basically everything. So which one is “better”?

I think the problem is that Fable 5 is probably a bit outdated right now.

Fable 5.1 or whatever they go with will be the stronger version vs Opus 5.

From about 2 hours of Opus 5 use , I would say it is quite impressive.

Here's another test of a cyberpunk ramen shop website. One thing I've found LLMs have a lot of difficulty with is angular cuts / elements that aren't easily representable with CSS. Cyberpunk aesthetics are generally a great test of that, since they have a lot of microglyphs / window decoration. Design source of truth: https://image.non.io/9d5fed20-b476-49d3-841b-37eb553fb88e.we... Opus 5 build: https://html.non.io/ne…

God damn, we are living in the future. I love this so much. Designs like this would never have seen the light of day in the cellphone incrementalism / corporate memphis era of tech. Now people can be weird and awesome again. This is 1980's cyberpunk / late-90's Matrix / early-00's sci-fi UI. Great ideas that died to frutiger aero (which isn't a bad design aesthetic) and flat design (which is). This is fun and it's go…

What do you mean designs like this? This is 2016-cyberpunk-neon-era inspired by video game interfaces, these are not uncommon at all. Google something like "discord cyberpunk theme" or "cyberpunk rice site:reddit.com/r/unixporn" and you'll find endless examples. This isn't suprising at all obviously.

I think the most important thing here is not absolute performance.

insane pricing: " Claude Opus 5 is available today on all platforms, priced at $5 per million input tokens and $25 per million output tokens (the same as Opus 4.8)"

"insane" that they kept the price the same and didn't jack it up, my bad for the ambiguity.
