ONE MODEL, DIFFERENT COMMUNITIES

Scored separately for each platform, with different samples and audiences. Platform scores are not simply averaged; scored counts exclude quota-only comments.
Scores range from 0 to 100. Select a platform for its trend and reviews. Latest opinion time is not crawler health.
What people think
One user added a mini router that dispatches harder coding slices to Sonnet 5.5, and the setup improved first-pass implementation quality. One user, after briefly reviewing Claude Sonnet 5.5's Thomson problem proof, sarcastically said anyone who finds inspiration from it should just become a computer.

Some responses claim this is Anthropic's excessive promotion, but I feel I need to stand up for Anthropic. The reason is simple—this is not Anthropic's release at all... The original message was from a company doing various LLM benchmarks called Vals.AI. Here is the original text: We asked ten Claude Sonnet 5.5 agents to use Lean to prove the lowest-energy arrangement of seven electrons on a sphere (the Thomson problem, with N=7). Within 15 hours, they produced a 17,895-line proof, accepted by the Lean kernel, showing that the answer is a pentagonal bipyramid.

有些回答说这是anthropic的过度宣传，我觉得我得为anthropic站一下台。理由很简单，这根本不是anthropic发的…… 原消息是一家做各种LLM Benchmark的公司Vals.AI发的，这是原文： We asked ten Claude Sonnet 5.5 agents to use Lean to prove the lowest-energy arrangement of seven electrons on a sphere (the Thomson problem, with N=7). Within 15 hours, they produced a 17,895-line proof, accepted by the Lean kernel, showing that the answer is a pentagonal bipyramid.

I learned through my testing that sonnet 5.5 sometimes spawns opus 5.5 subagents. Might be one of the main reasons why sonnet 5.5 feels a lot more expensive for people.
And, this is not about the API price, but the percentage weekly usage of the subscription.

I actually added a mini router in front of it this week, and the harder slices get dispatched to sonnet 5.5 instead, pretty effective so far, it improved first-pass implementation quality.

这玩意儿哪里都不如Opus 5.5，也是给A畜学到国产小参数做题家模型雷霆大思考刷分的精髓了

So I don't know what's your process but I would suggest models wise to just use Opus 5.5 high or medium as the orchestrator to supervise a Sonnet 5.5 high implementer and use 6.1 sol xhigh (or medium if you notice xhigh is not sustainable for you) as a reviewer.

It really depends on the task, but it's often either sonnet 5.5 high or opus 5.5 med.

I discussed a JEV-related question and found that Company A's models now have a certain characteristic.

我拿一个跟JEV相关的问题讨论了一下，发现A家的模型现在有个特点。

在智能体命令行编程测试 Terminal-Bench 4.0 中，它以 70.6% 的高分拿下 全球第一 ，相比 Sonnet 5 的 10.3% 属于跨越式暴涨

才发现Sonnet5.5还挺耐用啊

思考用更多token导致更慢

免费用户也能用几下sonnet5.5，反观隔壁免费用户只能用luna

同思考档位的sonnet 5.5 比 opus 消耗token更多，效率更低

单价只有Opus一半，额度还给得更多，还学会了O社时不时发重置次数

If Astra is that great, how come its code introduces so many bugs? Give Astra a complicated task on Ultra, and then after give the prompt "review" - you will get about 5 problems.
