I still feel like the difference between Sonnet and Opus is a bit unclear. Somewhere on Anthropic's website it says that Opus is the most advanced, but on other parts it says Sonnet is the most advanced and also the fastest. The UI doesn't make the distinction clear either. Then on Perplexity, Perplexity says that Opus is the most advanced, compared to Sonnet. And finally, in the table in the blogpost, Opus isn't eve…
Opus hasn't yet gotten an update from 3 to 3.5, and if you line up the benchmarks, the Sonnet "3.5 New" model seems to beat it everywhere. I think they originally announced that Opus would get a 3.5 update, but with every product update they are doing I'm doubting it more and more. It seems like their strategy is to beat the competition on a smaller model that they can train/tune more nimbly and pair it with outside-…
Why isn't Anthropic clearer about Sonnet being better then? Why isn't it included in the benchmark if new Sonnet beats Opus? Why are they so ambiguous with their language?
For example, https://www.anthropic.com/api says:
> Sonnet - Our best combination of performance and speed for efficient, high-throughput tasks.
> Opus - Our highest-performing model, which can handle complex analysis, longer tasks with many steps, and higher-order math and coding tasks.
And Opus is above/after Sonnet. That to me implies that Opus is indeed better than Sonnet.
But then you go to https://docs.anthropic.com/en/docs/about-claude/models and it says:
> Claude 3.5 Sonnet - Most intelligent model
- Claude 3 Opus - Powerful model for highly complex tasks
Does that mean Sonnet 3.5 is better than Opus for even highly complex tasks, since it's the "most intelligent model"? Or just for everything except "highly complex tasks"
I don't understand why this seems purposefully ambiguous?
