How Claude Opus compares
42 creators weighed in
"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
"We know that Claude is good at certain things and Astra is good at other things because we've pushed them. But if you're not in it and using it, you don't know."
Good at different things than GPT Astra; 5.5 is about 80% cheaper than Opus 5 for equivalent tasks
"It's more about taste and what you like and how you like to work than that they're worse than Anthropic. So, Anthropic's Opus 5.5 I use more because it's more like my style. It leaves more space for my thinking instead of filling out eve..."
Compared to GPT-6.1, which is close in quality but differs in taste

"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
"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
"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
"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..."
Beats Gemini Argon on his writing-similarity test and his PowerPoint benchmark

"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
"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)

"GLM 5.2 cost $6 per task versus $15 for Claude Opus 4.6. DeepSeek V4 Pro costs about $3 versus $12.50 for Opus 4.5."
More expensive per task than open-weight models GLM 5.2 and DeepSeek V4 Pro
"It actually beats Opus and GPT Soul on benchmarks while being 20 times faster and 20 times cheaper."
Outperformed by DeepSeek V1 Flash on benchmarks
"It is $30 to use Opus 4.8 for input plus output for 1 million tokens."
23x more expensive than DeepSeek V4
