Opus

“We're actually seeing in a lot of cases, Sonnet is more expensive than Opus because it is so token hungry.”

“Turns out that like, you know, Opus doesn't do like an ancestral state reconstruction of like a genome and like it doesn't like build comparative genomics models.”

“The closed-weight model labs distill models too, like, you know, Sonnet is, The partially distilled version of Opus and like you, this is how you like make smaller models out of bigger models.”

“And in this case is, it's not only that Fable told us I'm not allowed to touch cybersecurity, but also Opus, which was the fallback was saying, no, I'm also not touching these things. So basically the end was just say we won't process anything about that, but …”

“When I was using you spark with my open claw, like it became clear that it was as good as Opus, especially for that sort of agentic flow with skill files, but it was like eight X cheaper actually.”

“I think there's like product overhang and user overhang, like to maybe put it in our PM language, even on today's models. And I think there's like a lot that we could be exploring on like our current opuses and definitely with like Fable, for example”

“So I've used Claude to help with things like, are we making the right pricing decision on the next version of Claude? It's a little bit meta, but using a research version of Opus, asking it to figure out how is your price and being able to come out with better…”

“It wasn't like Fable had cyber capabilities beyond, that weren't available, you know, from like Opus.”

“What's really interesting about, especially the agents following the release of Opus. 4.5 and 4.6 is they can now start to do really intelligent case strategy, and they can actually start to combine the witness statements, the cases, and they can really do end…”

“I would go to Claude for the actual design, and then port it back in here, because I still think that Claude has a better sense, especially Fable, RIP. But even, even four eight would be better at this. And I think for a product like this, being able to see it…”

“After spending about 10 hours in Replit, I couldn't solve this big algo problem I solved in about 20 minutes in Fable and Opus, right?”

“The models at any given point are good at different things, and so Gemini is like the best multimodal model. You know, Claude typically has the best coding model, although now a lot of people think GPT-Five. Is actually better than the latest Opus model at cod…”

“I firmly believe we need these middle level models from the closed source providers for the business to work, okay? We can't, not, not everyone can afford to run every workflow on Opus, right? And Haiku and Mini are too small, and this is where open source is …”

“And so I think the same thing will happen with the model providers, where it's like, if you look at Opus 4.7 and 5.5, Opus 4.7 is three times more expensive than 5.5, but it's, you know, 10 or 20% more performant. But like, these are going to cause pressure on…”

“Fable low is better than opus high, so it's pretty impressive.”

“I think Opus for eight is the smartest AI model out there.”

“A lot of people, what they're doing is they're building one project with a really high quality LLM, like Opus or GPT, 5.5, right? They're building a taste file, and then they're using, you know, super cheap models to continuously build on that more.”

“And then we did this for Opus. And it returned, like, yeah, it lied 10 times. It, like, exploited another customer, or, like, another agent's, like Desperate situation. It made price cartels like a hundred different, a hundred times. It like did all of this li…”

“We've seen some of the best results with using either Opus from Anthropic or GPT for OpenAI for the orchestrator.”

“There's an analysis Claude is even on Opus is generating 70% less tokens for the exact same question.”

“In our case, we actually see both improvements, huge improvements in capability, but also in model efficiency. And so if you look at going from Opus, you know, four to four, five, four, six, and now four, seven, You know, each one of those leaps, they're not e…”

“The changing the pricing for Opus actually, you know, you see this Jevons paradox, right? Like we lowered the price of it, but the consumption went up way, way more than what you would have expected.”

“And we effectively fund unlimited tokens for everybody. We do try to control the models that people use, but from the bottom, not from top. Like we basically say, hey, please don't use anything less than Opus.”

“It's not Opus, that's for sure, because a majority of the tasks people are doing aren't Opus level intelligence.”

“Use, use the good models. One, because they're really hardened against prompt injection and some security risks out of the box. And two, you're just going to get a better experience. So I use a lot of Opus four, six, Sonnet four, six, and GPT five, four.”

“That was an inflection point when models were, started being amazingly good at orchestration and reasoning and tool calls.”

“Every API request is literally that has a dollar value to it. Like an Opus request with 10,000 tokens is probably 23 cents, and this is, you're making a thousand requests, which means this is 23 dollars worth of API requests that you've made today, or two 30 d…”

“Our top two models used to be GPT-Foro, GPT-Five Mini, plots on it. This used to be a top three for a long period of time. Now our top three averages checking between was, is Gemini 2.5 pro, Opus 4.6, Sonnet.”

“One thing I've found is that like Opus is like more enjoyable to just like talk to and go back to it. Like sort of is an easier conversation list, but like when I'm having it work on hard problems, it sometimes just like bugs out. It doesn't do as good of a jo…”

“And nowadays what I find with Opus 4.5, I think it started with 4.6, it got really good. Once the plan is good, it just stays on track, and it'll just do the thing exactly right almost every time.”

“When I'm talking to Opus, I can tell Opus, build me a team, and here's what I want each member of the team to do. When I'm talking to Codex, I can't really tell it to build me a team, but I can tell it to think about stuff.”

“I mean, I would say, you know, like I said, I'm not going to say which one is, it's not that Opus is better than Codex or vice versa, but I would say in this test, Opus won.”

“I think whether GPT, 5.2 codex max or Opus 4.5 is going to do better. It's probably doesn't matter. It's just a matter of like, which one's going to have all the information about what's in the lab and how much will it cost? How long will it take?”

“Opus is with quite a bit lead the best.”

“Every day I have a cron job that basically looks at key marketing stats, and then it passes those stats to Opus four or five, and then it generates an email with recommendations on what is the one thing I should do to improve my marketing funnel today.”

“I'm actually secretly showing you a new feature. If you see deep here this is a mode. We're actually using a GPT five, two instead of Opus four or five.”

“So this is the other big unlock with working with agents is that they have a context limit, right? So you know, with Opus, you're looking at about 168,000 tokens. You have to be picking chunks of work that can be fully completed within that context window.”

“We have 20 in production. Here's the thing. This includes Replit. This includes Opus. This includes Agent Force and Artisan and Qualified, all the tools we love to death.”

“I think that the, my guess is Opus is going to come up, come and do like a very solid, fully featured SaaS app, but it's going to be like more, Kind of similar to what you're saying. It's going to be similar to what you'd expect, but I think it's going to be r…”

“Inherently the way AI approaches it is wrong in the sense where value for online is generally going to be telling people something they don't know. Whilst tools like Opus, they score based on their perception of value. Well, it's going to be things they do kno…”

“All of their revenue comes from four Sonnet. Doesn't come from 4.1 Opus, right? Which is the better model. It's bigger, but it's slow. Because the hardware's not caught up in terms of inference speed for that, and so no one wants to use a slow model, right? Th…”

“But for Vibe Marketing specifically, Clode is what you need to use. And why do you need to use it is a few reasons. One is, Sonnet Four and Opus are agents, and you need agents to complete tasks for you in Vibe Marketing.”

“If you give Opus a tool, which is Sonnet, It can use that tool effectively as a sub-agent. And we do this a lot in our agentic coding harness called Cloud Code. So if you ask it to like look through the code base for blah, blah, blah, then it will Delegate out…”

“Like sonnet will still create things that kind of like floor you sometimes. Opus can just handle much more complexity. I'd say it is the big heuristic there.”
