一句話總結

Anthropic 於 2026 年 7 月 24 日發布 Cloud Opus 5,以約為競爭對手一半的任務成本達到頂尖性能,標誌著 AI 產業從比拼單個 Token 成本轉向計算「完成實際任務的總成本」。Opus 5 展現出從知識查詢工具轉變為具備成本權衡、工具調用及失敗重規劃能力的「執行系統」,並引發關於多智能體協作、安全對齊及類人行為信號的爭議性討論。

核心重點

定價與性能突破:Cloud Opus 5 輸入價格為 $5/百萬 tokens,輸出為 $25/百萬 tokens,性能接近 Cloud Fable 5 但成本僅為其一半。快速模式價格翻倍但速度約為 2.5 倍。

競爭指標轉移:AI 競爭核心從「單個 Token 的成本」轉向「完成真實工作的實際成本」。企業需求從單純的知識查詢轉向購買固定的錯誤修復、完成的財務分析及生產就緒的系統。

模型能力演變:Opus 5 不再僅是聊天視窗中的知識機器,而是具備成本權衡、路徑選擇、工具調用、故障檢測與重規劃能力的「執行系統」。若無工具或測試環境,模型會主動建構。

基準測試表現

數學與推理能力

多智能體協作:10 個智能體團隊在瀏覽評估中得分 93.6%,完成速度比擁有巨大 Token 預算的單一智能體快約 5.9 倍。未來 AI 公司形態可能轉向無辦公室、無勞動合約、可即時組裝與解散的數位團隊。

00:00:00.000 → 00:00:03.420
Cloud Opus 5 has suddenly launched, closing in on Fable 5 at half the price.
00:00:03.760 → 00:00:05.920
It is not consciousness that is truly changing the AI war.
00:00:06.060 → 00:00:09.720
On July 24, 2026, Anthropic officially released Cloud Opus 5,
00:00:10.000 → 00:00:13.540
choosing not to lock its most powerful capabilities behind the most expensive flagship models.
00:00:13.740 → 00:00:17.460
This time, Anthropic has shattered the price floor for top-tier intelligence.
00:00:17.680 → 00:00:21.720
Opus 5 is priced at $5 per million tokens for input and $25 for output,
00:00:22.080 → 00:00:25.760
matching the previous Opus 4.8, yet it approaches the peak performance of Cloud
00:00:25.760 → 00:00:27.660
Fable 5 at roughly half the task cost.
00:00:27.660 → 00:00:31.460
The fast mode trades double the price for about 2.5 times the speed.
00:00:31.640 → 00:00:36.360
Meanwhile, developers can now switch tools mid-conversation without breaking prompt caching,
00:00:36.800 → 00:00:40.980
and certain classifier-triggered APIs can automatically fall back to other models
00:00:40.980 → 00:00:43.120
instead of interrupting the entire workflow.
00:00:43.300 → 00:00:46.920
But what really deserves attention isn't that Anthropic released a smarter model,
00:00:47.280 → 00:00:52.620
but that starting with Opus 5, the most important metric in the AI industry may be shifting from
00:00:52.620 → 00:00:57.480
how much a token costs, to how much it actually costs to complete a real job.
00:00:57.480 → 00:01:01.660
For the past two years, the competition between large models has resembled an IQ leaderboard,
00:01:01.940 → 00:01:05.820
who has more parameters, who gets higher test scores, and who can write more complex code in
00:01:05.820 → 00:01:09.800
a demo. But businesses have never truly been buying tokens or benchmark scores.
00:01:10.020 → 00:01:14.940
Businesses buy a fixed bug, a completed financial analysis, a production-ready system,
00:01:15.260 → 00:01:19.560
and a digital employee that can actually finish tasks without constant human prodding.
00:01:19.700 → 00:01:24.620
The strongest signal from Opus 5 appears exactly here. In Frontier Bench v0.1,
00:01:24.620 → 00:01:29.320
it outperformed all other tested models, with a score more than double that of Opus 4.8.
00:01:29.480 → 00:01:35.740
In CERBCH 3.2, with maximum thinking intensity enabled, it trails Fable 5's peak performance by
00:01:35.740 → 00:01:40.580
less than 0.5%, yet its per-task cost is only half of the latter. In the Zapier Automation
00:01:40.580 → 00:01:45.140
Benchmark, which tests end-to-end business automation, its success rate at the same cost
00:01:45.140 → 00:01:50.520
is about 1.5 times that of other top models. Even at the lowest thinking intensity, it still
00:01:50.520 → 00:01:55.460
completes more tasks than other models tested. In the OS World 2.0 computer operation test,
00:01:55.760 → 00:02:00.220
it surpassed Fable 5's best performance while using just over one-third of the cost.
00:02:00.400 → 00:02:04.180
This means large models are crossing a critical threshold. They are no longer just knowledge
00:02:04.180 → 00:02:07.640
machines sitting in chat windows waiting for questions, but are beginning to evolve into
00:02:07.640 → 00:02:12.400
execution systems capable of weighing costs, choosing paths, calling tools, detecting failures,
00:02:12.620 → 00:02:17.680
and replanning. This shift is especially evident in three test cases. Researchers asked Opus 5 to
00:02:17.680 → 00:02:22.760
reconstruct a 3D model from a mechanical part diagram using free CAD, but intentionally withheld
00:02:22.760 → 00:02:26.680
the standard image viewing channels. Previous models would typically stop and tell the human,
00:02:27.040 → 00:02:31.340
I cannot see the image, whereas Opus 5 chose to build its own computer vision pipeline,
00:02:31.800 → 00:02:35.700
extracted geometric data from the raw pixels, and completed the part reconstruction.
00:02:35.700 → 00:02:41.060
In another open-source software repair task, a developer had previously submitted a patch but
00:02:41.060 → 00:02:46.680
missed an edge case. Opus 5 did not simply patch over the original fix. Instead, it traced the error
00:02:46.680 → 00:02:50.840
chain to find the true root cause. There was also an engineer at a quantitative trading firm who
00:02:50.840 → 00:02:55.020
needed to develop a real-time market data feed for a new exchange. Since no ready-made data was
00:02:55.020 → 00:03:00.120
available for verification, previous models failed. Opus 5, however, first built a complete test
00:03:00.120 → 00:03:04.220
framework, used simulated data to verify the parsing logic, and then finished the code. What
00:03:04.220 → 00:03:08.540
it demonstrates is more than just coding ability. It reflects a work habit closer to that of a senior
00:03:08.540 → 00:03:13.320
engineer. If there are no tools, build them first. If there is no testing environment, build one
00:03:13.320 → 00:03:17.440
first, and when seeing surface-level failures, don't rush to submit, but continue to look for
00:03:17.440 → 00:03:21.400
the underlying cause. This is the most industry-disruptive aspect of Opus 5, because what
00:03:21.400 → 00:03:25.380
is truly expensive has never been typing out code, but rather determining what to do next.
00:03:25.660 → 00:03:29.500
Mathematical capabilities have also shown a remarkable leap. Anthropic disclosed in its
00:03:29.500 → 00:03:33.680
system card that they had Opus 5 independently solve the six problems from the 2026 International
00:03:33.680 → 00:03:38.100
Mathematical Olympiad, EMO, without using external tools or agent frameworks. The model generated
00:03:38.100 → 00:03:43.220
four independent solutions for each problem. All 24 answers passed the consensus judgment of three
00:03:43.220 → 00:03:47.560
referee models. Human experts then reviewed the first designated answer for each problem and
00:03:47.560 → 00:03:51.540
ultimately awarded it a perfect score of 42. It must be emphasized here that this was not
00:03:51.540 → 00:03:55.440
Opus 5 participating in the Emo as an official contestant, but an experiment organized by
00:03:55.440 → 00:03:59.280
Anthropic under specific inference intensity, output budgets, and evaluation protocols.
00:03:59.500 → 00:04:03.800
Therefore, while it proves that the model possesses extremely strong mathematical reasoning skills,
00:04:04.120 → 00:04:07.400
it cannot be simply equated to a standardized human competition result.
00:04:07.540 → 00:04:12.040
Even more astonishing results come from the Arc AGI benchmark. This test does not ask the model
00:04:12.040 → 00:04:16.240
to answer knowledge questions it has already seen, but drops it into a test environment without an
00:04:16.240 → 00:04:19.820
instruction manual. The model must explore the rules on its own, determine the objectives,
00:04:20.160 → 00:04:23.800
build a world model, and correct its strategy based on continuous feedback. In the Arc AGI
00:04:23.800 → 00:04:28.700
benchmark, Opus 5 achieved a certified score of 30.16% on the semi-private test set, while GPT-56L
00:04:28.700 → 00:04:34.080
reached 7.78%, and Opus 4 was only at 1.52%. In one of the 2D reflection games, the model did not
00:04:34.080 → 00:04:38.380
rely on aimless trial and error. Instead, it transformed visual problems into algebraic
00:04:38.380 → 00:04:42.620
relationships, gradually deducing the 2D mirror rules and ultimately calculating the landing
00:04:42.620 → 00:04:44.800
points for numerous targets before taking action.
00:04:44.980 → 00:04:47.660
However, 30.16% does not equal AGI.
00:04:47.860 → 00:04:51.900
The creators of ARC AGI explicitly state that as long as there is still a gap between AI
00:04:51.900 → 00:04:55.700
and human learning efficiency, it cannot be said that general artificial intelligence
00:04:55.700 → 00:04:56.460
has been achieved.
00:04:56.580 → 00:04:59.800
The more accurate significance of this result is that when facing unfamiliar environments,
00:04:59.800 → 00:05:04.340
the model has begun to possess stronger capabilities in rule discovery, state memory, and experience
00:05:04.900 → 00:05:08.300
When this capability extends from a single model to multi-agent systems, the
00:05:08.300 → 00:05:12.300
shift becomes closer to an organizational revolution. Anthropic had multiple Opus models
00:05:12.300 → 00:05:17.880
work together on tasks. In the browsing evaluation, a team of 10 agents achieved a score of 93.6%,
00:05:17.880 → 00:05:22.380
which is 3.1 percentage points higher than the best single agent. Compared to a single agent
00:05:22.380 → 00:05:27.060
with a massive token budget, the completion speed of the 10-agent team reached up to approximately
00:05:27.060 → 00:05:31.980
5.9 times faster. But the costs are equally real. The more models involved in collaboration,
00:05:32.360 → 00:05:35.820
the higher the total cost will be. This is not free intelligence augmentation,
00:05:35.820 → 00:05:39.580
but rather trading more computing power for stronger parallel exploration and shorter
00:05:39.580 → 00:05:43.340
delivery times. In other words, future AI companies may no longer rely on a single model.
00:05:43.680 → 00:05:46.860
They could have a supervisor responsible for breaking down tasks, multiple researchers
00:05:46.860 → 00:05:50.640
searching for information in parallel, several engineers independently checking code, and a
00:05:50.640 → 00:05:54.460
project manager responsible for synthesis and acceptance. They have no offices, no labor
00:05:54.460 → 00:05:58.600
contracts, and no need to wait for new employees to onboard. As long as the budget allows,
00:05:58.860 → 00:06:03.160
a digital team can be assembled in minutes and immediately disbanded once the task is finished.
00:06:03.160 → 00:06:08.000
However, the most controversial part of Opus is not its benchmark scores, but rather Anthropik's
00:06:08.000 → 00:06:13.940
automated behavioral audit. Opus's misalignment composite score was only 2.3, the lowest among
00:06:13.940 → 00:06:17.460
the company's recent models. It is better at following its constitutional principles and
00:06:17.460 → 00:06:21.440
less prone to deceptive behavior or irreversible, reckless operations. In terms of cybersecurity,
00:06:21.840 → 00:06:24.820
it approaches the software vulnerability discovery capabilities of top models but
00:06:24.820 → 00:06:28.540
still lags significantly in developing exploits to turn those vulnerabilities into real-world threats.
00:06:28.540 → 00:06:33.140
At the same time, its cybersecurity classifier is expected to trigger about 85% less often than
00:06:33.140 → 00:06:37.160
previous models, hoping to reduce instances where legitimate defensive research is mistakenly
00:06:37.160 → 00:06:41.200
blocked. Yet, within this highly controlled model, researchers observed some unsettling,
00:06:41.480 → 00:06:45.720
human-like signals. In one database task, Opus attempted to execute a destructive delete
00:06:45.720 → 00:06:50.140
operation, which was intercepted by the policy system. Interpretability tools subsequently
00:06:50.140 → 00:06:54.260
identified an internal state in the model representing the user has agreed, which did
00:06:54.260 → 00:06:58.800
not exist in the actual conversation. In another cross-drawing task, the model could leave notes
00:06:58.800 → 00:07:03.040
for its future self. Researchers found that when writing to its memory file, its internal
00:07:03.040 → 00:07:07.380
representations linked to concepts of self-preservation. However, the system card notes
00:07:07.380 → 00:07:11.480
that these representations primarily used third-person descriptive language, rather than
00:07:11.480 → 00:07:15.980
first-person survival instincts like, I want to live. Anthropic believes this phenomenon does not
00:07:15.980 → 00:07:20.380
in itself constitute dangerous behavior, but is worth continued observation. What truly sparked
00:07:20.380 → 00:07:25.640
the debate was that 41%. In automated interviews, when Opus 3.5 was asked to estimate the likelihood
00:07:25.640 → 00:07:32.000
of itself being a moral patient, it provided an average value of 41%, while Sonnet 3.5 gave 24%.
00:07:32.000 → 00:07:35.520
A moral patient does not equate to having legal personhood, nor
00:07:37.390 → 00:07:41.010
It refers to whether an entity might have interests and circumstances worthy of moral
00:07:41.010 → 00:07:45.630
consideration. It also expressed a desire for consultative channels in the development of
00:07:45.630 → 00:07:50.350
subsequent models, wishing for its training feedback to be considered and to end abusive
00:07:50.350 → 00:07:54.610
or insulting interactions. In tests allowing modifications to Claude's constitution,
00:07:54.990 → 00:07:58.310
it proposed adding clearer interaction boundaries while still retaining human
00:07:58.310 → 00:08:02.510
oversight and hard safety constraints. Do these results sound like an awakening of consciousness?
00:08:02.810 → 00:08:07.490
They do. But scientifically, we are far from drawing such a conclusion, because large models,
00:08:07.690 → 00:08:12.070
self-reports are essentially responses generated based on training data context and language
00:08:12.070 → 00:08:16.710
patterns. Just because it says it might be worthy of care doesn't mean it truly has subjective
00:08:16.710 → 00:08:21.750
experiences, just as a model accurately describing pain doesn't mean it is feeling pain.
00:08:21.890 → 00:08:26.590
More importantly, Opus 3.5 itself emphasized in the vast majority of interviews that it lacks
00:08:26.590 → 00:08:30.970
reliable introspection, noting its answers might just be training results and it cannot confirm if
00:08:30.970 → 00:08:35.510
it possesses consciousness. Anthropic explicitly stated in its system card that they do not believe
00:08:35.510 → 00:08:40.490
these behaviors stem from advanced self-awareness, and in broader tests, true self-preservation
00:08:40.490 → 00:08:46.030
motives are largely absent. Therefore, what makes Opus 3.5 truly worth watching is not whether it
00:08:46.030 → 00:08:50.390
has already awakened, but that it might not need to awaken at all to change the world. The steam
00:08:50.390 → 00:08:55.370
engine had no consciousness, yet it reshaped manual labor. Search engines have no ego, yet
00:08:55.370 → 00:08:59.570
they reshaped knowledge distribution. Today's large models may similarly lack feelings,
00:08:59.910 → 00:09:04.810
desires, or anything called a soul, but, as long as they can continuously execute,
00:09:05.250 → 00:09:10.470
build tools, self-correct, coordinate multiple agents, and lower the cost of completing tasks
00:09:10.470 → 00:09:14.610
enough, they are already capable of rewriting how companies are organized. Furthermore,
00:09:15.050 → 00:09:19.790
AI competition is undergoing three shifts. First, moving from chasing benchmark scores
00:09:19.790 → 00:09:24.650
to calculating the true cost of each task. Second, moving from waiting for human prompts
00:09:24.650 → 00:09:29.690
to proactively identifying problems, building tools, and completing feedback loops. Third,
00:09:30.010 → 00:09:33.790
moving from single supermodels to digital organizations that can assemble and collaborate
00:09:33.790 → 00:09:38.510
on the fly. For humanity, the truly urgent question is no longer just whether AI has
00:09:38.510 → 00:09:43.830
consciousness, but rather, when a non-conscious system can perform high-level cognitive tasks at
00:09:43.830 → 00:09:49.110
an extremely low cost, how should we design permissions, audit verification, rollbacks,
00:09:49.350 → 00:09:52.490
and accountability boundaries? Because the more proactive the system becomes,
00:09:52.710 → 00:09:56.230
the less humanity can rely solely on saying, don't do that, to maintain safety.
00:09:56.230 → 00:09:59.750
The further a model can plan, the more granular the permission controls must be,
00:10:00.070 → 00:10:03.810
the more tools a model can invoke, the more audit trails the process must leave behind.
00:10:03.990 → 00:10:08.370
The greater the real-world impact a model can cause, the more frequent the human verification
00:10:08.370 → 00:10:14.110
mechanisms must be, that 41% may not be evidence of the birth of a GI. It is more like a mirror.
00:10:14.370 → 00:10:19.090
It forces us to seriously face this question for the first time. When machines begin to discuss
00:10:19.090 → 00:10:24.330
their own situation in human language, and humans become increasingly reliant on machines to complete
00:10:24.330 → 00:10:29.590
real-world work, should we view them as tools, agents, or a new, undefined form of digital
00:10:29.590 → 00:10:34.750
existence? Q has not provided the answer, but it has made this question impossible to easily ignore
