Better models are always more expensive. That’s a rule everyone accepted while using AI. But this time, that rule has been broken. Anthropic has released Claude Opus 5.5. It is the first model in the new 5.5 family. The
00:10
Speaker A
first line of the announcement says this: It matches Sonnet 5.1 in most tasks but costs 40% less to run than Opus 5. It has top-tier performance, but the price has actually gone down.
00:18
Speaker A
There is one condition attached. It is based on default settings and typical workloads. Let’s break down the numbers to see if that’s true. If you watch to the end, I’ll show you the most profitable settings. First, shall we look at the rankings? There are nine
00:28
Speaker A
tests in the announcement. Subjects like coding, knowledge, work, and computer use. Opus 5.5 is ranked first in seven of them. It outperformed Sonnet 5.1, which took the same tests, in almost every subject. So, what about the two it lost? Both were lost to
00:39
Speaker A
OpenAI’s GPT-6 Astra. It narrowly lost the work automation test, 40.0 to 41.4, a 1.4-point gap. The scientific research test was 58.7 to 64.6. It clearly lost that one. However, if you stop after looking at the score table, you miss half the announcement. Think
00:52
Speaker A
about a taxi. Even if the meter rate is low, the fare is higher if the driver takes the long way. AI is the same.
00:56
Speaker A
Even with cheap tokens, it’s expensive if it uses too many to solve a problem. So, what matters isn’t the rate, but the final fare when you arrive. The announcement shows exactly that graph. The first graph is the terminal benchmark. It’s a coding
01:07
Speaker A
test where AI completes multi-step tasks in a terminal window. There’s an interesting ranking shift here.
01:12
Speaker A
Claude wasn't actually number one in this test before. When comparing their highest settings, GPT-6 Astra was 57.9 and Claude’s top model Sonnet 5.1 was 55.8. But Opus 5.5 scored 66.4. It reclaimed the top spot in coding it had
01:24
Speaker A
lost. How about the costs? Opus 5.5 at default settings beats Opus 5 at its highest settings. The cost is about one-fifth. Anthropic stated that it costs about 40% less to achieve the same score as Astra. Now, for today’s highlight. Let me give you a quiz.
01:37
Speaker A
Which score is higher: Opus 5.5 with depth of thought maxed out, or Opus 5.5 with default settings? It must be the highest setting, right? No. There is a test called Frontier Code. It checks if the code fixed by AI is actually worth
01:48
Speaker A
adopting. Here, the default setting was 54.6, and the max setting was 54.4; the default was higher. Turning the heat to maximum doesn't always make ramen taste better, right? That is exactly the picture. Moreover, this 54.6 is higher than Astra's top score of 53.3. The
02:01
Speaker A
cost per problem is about 1. The same results appeared in the GDP-based test, where 44 jobs were performed in real scenarios. The default setting Opus 5.5 beat the top-tier Astra at about 1/cost. I believe this is the core of this
02:11
Speaker A
announcement. It means you don't have to enable expensive settings, at least for these tests. So, what are the unit prices exactly? It’s 4 dollars for input and 20 dollars for output per million tokens. That’s 20% lower than Opus 5. For reference, Fable 5.1, based
02:22
Speaker A
on their own announcement, is 10 dollars for input and 50 dollars for output. Looking at the unit price alone, it’s not even half. The bigger drop is in cache reading. It dropped by 60% to 0.2 dollars per million tokens.
02:31
Speaker A
Cache reading is like the cost of taking side dishes out of the refrigerator. Instead of cooking from scratch every time, you reuse what’s already made. According to the announcement, most costs for coding or agent tasks come from this cache
02:39
Speaker A
reading. So, the price reduction is felt much more significantly than you might think. The speed has also become over 30% faster than Opus 5. Let's stop talking about numbers here. There is one more change that users will feel immediately. It’s the tone of voice.
02:49
Speaker A
Have you ever felt that the responses from Opus 5 were difficult? Anthropic acknowledged that this was one of the complaints they heard most often. Opus 5.5 puts important content at the beginning and uses less jargon or strange expressions. It also follows
02:59
Speaker A
the writing rules I set well. One tester put it this way: "It writes the way I write." Safety features have also changed. Most cybersecurity tasks are now handled by Opus 4.8 instead. The biology field also has similar safety
03:09
Speaker A
measures as Fable 5.1. Attempts to cross set boundaries have decreased by about 85% compared to Opus 5. You can use it starting today. It's available on the Claude app, as well as via API, AWS, Google Cloud, and Microsoft Azure.
03:19
Speaker A
There is also good news for subscribers. Usage limits for Pro, Max, and Team plans are increasing by five hours. I also saw a usage limit reset, which you can save and use whenever you want.
03:27
Speaker A
It’s like an emergency fund you pull out when you’re in a pinch. And Sonnet 5.5 and Haiku 5.5 are said to be coming out in a few weeks. I’ll summarize them for you when they arrive. In short, it’s better and cheaper,
03:35
Speaker A
so try using the default settings before the expensive ones. Give it a try today. If this was helpful, please like and subscribe. I will see you again with a better video next time.
