How Claude Opus compares
50 creators weighed in
"These models, well, especially ChatGPT and Claude, are the ones that power the various different agents that I work with... When I do stuff with Claude Code in the terminal or on my computer, that is powered by Opus 5.5 these days."
Alongside ChatGPT and Perplexity
"Claude Opus 5.5 right now, in my opinion, at least for the things that I'm doing, is the best at coding. And so it's best at creating apps, especially if it is very front-end focused... GPT-6 Soul is also frontier and it's amazing. It's ..."
Compared to GPT-6 Soul, which he says is not as good at front-end design
"And so even though I really love Opus 5.5 as a model and even though it does really good work, the performance is so slow and you really feel that in a personal agent."
Slower than Codex's GPT ultrafast models and Muse
"I think I've just been spoiled lately by Opus 5.5. I know, I know. Your GPT girl here has been using Opus 5.5 because for creative tasks, for design, for video, for art, it is just the best on the market right now. I'll do an episode in ..."
Outperforms Muse Wonder on creative and front-end design; she normally prefers GPT
"Yeah, I mean the models change every day. Right now, Opus 5.5, that's amazing. And then the GPT six, Luna and Opus, those are great. Yeah. And you get tons of usage from that for your 20 bucks a month."
Alongside OpenAI's GPT-6 Luna

"In my opinion, these models don't do anything better than Opus 5.5. Opus 5.5 is the best model in the world right now. Use Opus 5.5. And so for most of my coding stuff or anything that requires a lot of intelligence, I have just been usi..."
Better than Gemini 4 Argon and Muse Wonder at the same price
"If you want to compare that against the best run so far of the models I've tested, this is Opus 5.5... it has these much more complex curved shapes."
Better than Gemini Argon's primitive shapes
"It's just not as detailed as Claude Opus 5.5. Opus 5.5 is just so amazing at adding detail."
More detailed than Gemini Argon
"I am a Claude girly through and through for writing, particularly with Opus 5.5 and Sonnet 5.5 coming out... Part of the reason I prefer Claude is that Claude talks more like me naturally."
Compared with Gemini Argon, which has better editorial judgment
"Opus on this task, it's much cleaner. It's just one idea per slide. So I would say that I'm still going to use Opus for PowerPoints... At least from my writing, I think Claude writes much closer to what I published naturally... I find Cl..."

"Anthropic puts out the best models for life sciences today. I run a life sciences R&D organization. We use their models. They're incredible. They're better than other models. And so we want to use them."
Better than other models for life sciences; cheaper open-weight models used for coding and internal workflows instead
"I couldn't solve this big algo problem — I solved it in about 20 minutes in Claude Opus. By using Claude plus Opus, I was able to get to the heart of the problem in an algorithm I could not understand. I lost a day using the n minus one ..."
Compared to using step-down/open-source models in Replit which wasted a full day without solving the problem
"We ran an experiment where we did Claude by itself, then we did us plus Claude. When you use our harness with Claude, it was simultaneously 1.4x cheaper and 1.5x faster than just using Anthropic Opus 4 alone."
Compared to 8090's software factory harness wrapping Claude, and to the best frontier open-source model with their harness
"Even Qwen models are able to have similar detection capabilities as Opus 4.8 with 80% cheaper because they're open-weight models."
Qwen open-weight models achieve similar vulnerability detection at 80% lower cost
"If open models really accelerate and then beat Opus 5 or Fable squarely across all categories, then that would be a big business risk to them going public."
Mentioned alongside Fable as top closed-source models that open-source models would need to beat

"We're able to deliver the same performance as — honestly, Opus 5, which is now I guess we're dating ourselves — Opus 5 is frontier-level intelligence. We're able to serve it; it's the same engagement rate, the same AB test performance, t..."
Used as a performance benchmark that Instinct claims to match at much lower cost
"It's about as powerful as Opus 4, but it's faster and cheaper than the Opus model. Grok 4.5 is $8 per 1 million tokens input plus output — almost four times cheaper than Opus 4."
Used as the primary benchmark for Grok 4.5 — Grok 4.5 described as comparable in quality but ~4x cheaper and faster
"It takes this GLM 5.2 into the arena with some of the best, like Claude Opus 4.8. Almost all of these Chinese LLMs and agents are open source."
Used as a benchmark against Z.ai's GLM 5.2
"It's going to code just as well as Opus 4. If you compare this to the cost of an Opus or a GPT 5.5, this is a steal."
Used as the intelligence and cost benchmark that GLM 5.2 is being compared against
"Get ready for Deep Seek 4, 20x over current US company LLM, even Opus 4.6 and Codex."
Used as benchmark for Deep Seek 4 comparison
"At times I've been a bit pooh-poohing of distillation. This is obviously distillation of Opus 5.5, like if you look at the capabilities that it kind of did."
Kimi K3.1 Pro distilled from it
"Their whole sales pitch in orchestration is look, we're going to use Opus 5.5 as an orchestrator, but then we're going to use Kimi K3 or Qwen as a submodel at half or a third or a fifth the price."
Paired with cheaper Kimi K3 or Qwen submodels
"Fable was almost certainly pre-trained off of a common corpus and probably post-trained off of a good deal of the same synthetic corpus as earlier models like Opus 4.8. So the signatures would be reasonably expected to rhyme if K3 were b..."
Referenced as a prior model whose training corpus overlaps with Fable 5, potentially explaining similarities with Kimi K3
"K3 beats Anthropic's Opus 4.8 and OpenAI's GPT 5.5 on most coding and agent tasks."
Kimi K3 reportedly beats it on most coding and agent tasks.
"They distilled data clearly from Opus and others. Sonnet is $20 or Opus is $40 and I think Fable is $60."
Compared to Kimi K3 ($15/million tokens) and DeepSeek ($1/million tokens)

What creators say
"Generally we default to Opus 5.5. Opus 5.5 is still like a great everyday daily driver. As everyone knows, it's an amazing model. It's just really reliable, it's fast, it's efficient, it's also just high quality on daily work."
