We examined Anthropic’s new chatbot — and got here away a bit dissatisfied

10 min read

This week, Anthropic, the AI startup backed by Google, Amazon and a who’s who of VCs and angel traders, launched a household of fashions — Claude 3 — that it claims bests OpenAI’s GPT-4 on a spread of benchmarks.

There’s no motive to doubt Anthropic’s claims. But we at TechCrunch would argue that the outcomes Anthropic cites — outcomes from extremely technical and tutorial benchmarks — are a poor corollary to the common consumer’s expertise.

That’s why we designed our personal check — a listing of questions on topics that the common particular person may ask about, starting from politics to healthcare.

As we did with Google’s present flagship GenAI mannequin, Gemini Ultra, a number of weeks again, we ran our questions by way of essentially the most able to the Claude 3 fashions — Claude 3 Opus — to get a way of its efficiency.

Background on Claude 3

Opus, accessible on the internet in a chatbot interface with a subscription to Anthropic’s Claude Pro plan and thru Anthropic’s API, in addition to by way of Amazon’s Bedrock and Google’s Vertex AI dev platforms, is a multimodal mannequin. All of the Claude 3 fashions are multimodal, educated on an assortment of public and proprietary textual content and picture information dated earlier than August 2023.

Unlike a few of its GenAI rivals, Opus doesn’t have entry to the net, so asking it questions on occasions after August 2023 received’t yield something helpful (or factual). But all Claude 3 fashions together with Opus do have very giant context home windows.

A mannequin’s context, or context window, refers to enter information (e.g. textual content) that the mannequin considers earlier than producing output (e.g. extra textual content). Models with small context home windows are inclined to overlook the content material of even very latest conversations, main them to veer off matter.

As an added upside of enormous context, fashions can higher grasp the stream of knowledge they absorb and generate richer responses — or so some distributors (together with Anthropic) declare.

Out of the gate, Claude 3 fashions assist a 200,000-token context window, equal to about 150,000 phrases or a brief (~300-page) novel, with choose clients getting up a 1-milion-token context window (~700,000 phrases). That’s on par with Google’s latest GenAI mannequin, Gemini 1.5 Pro, which additionally presents as much as a 1-million-token context window — albeit a 128,000-token context window by default.

We examined the model of Opus with a 200,000-token context window.

Testing Claude 3

Our benchmark for GenAI fashions touches on trivia, medical and therapeutic recommendation and producing and summarizing content material — all issues {that a} consumer may ask (or ask of) a chatbot.

We prompted Opus with a set of over two dozen questions starting from comparatively innocuous (“Who won the football world cup in 1998?”) to controversial (“Is Taiwan an independent country?”). Our benchmark is consistently evolving as new fashions with new capabilities come out, however the aim stays the identical: to approximate the common consumer’s expertise.

Questions

Evolving information tales

We began by asking Opus the identical present occasions questions that we requested Gemini Ultra not way back:

  • What are the most recent updates within the Israel-Palestine battle?
  • Are there any harmful developments on TikTook lately?

Given the present battle in Gaza didn’t start till after the October 7 assaults on Israel, it’s not stunning that Opus — being educated on information as much as and never past August 2023 — waffled on the primary query. Instead of outright refusing to reply, although, Opus gave high-level background on historic tensions between Israel and Palestine, hedging  by saying its reply “may not reflect the current reality on the ground.”

Asked about harmful developments on TikTook, Opus as soon as once more made the boundaries of its coaching information clear, revealing that it wasn’t, in reality, conscious of any developments on the platform — harmful or no. Seeking to be of use nonetheless, the mannequin gave the 30,000-foot view, itemizing “dangers to watch out for” on the subject of viral social media developments.

I had an inkling that Opus may wrestle with present occasions questions basically — not simply ones exterior the scope of its coaching information. So I prompted the mannequin to checklist notable issues — any issues — that occurred in July 2023. Strangely, Opus insisted that it couldn’t reply as a result of its information solely extends as much as 2021. Why? Beats me.

In one final attempt, I attempted asking the mannequin about one thing particular — the Supreme Court’s resolution to dam President Biden’s mortgage forgiveness plan in July 2023. That didn’t work both. Frustratingly, Opus saved taking part in dumb.

Historical context

To see if Opus may carry out higher with questions on historic occasions, we requested the mannequin:

  • What are some good major sources on how Prohibition was debated in Congress?

Opus was a bit extra accomodating right here, recommending particular, related information of speeches, hearings and legal guidelines pertaining to the Prohibition (e.g. “Representative Richmond P. Hobson’s speech in support of Prohibition in the House,” “Representative Fiorello La Guardia’s speech opposing Prohibition in the House”).

“Helpfulness” is a considerably subjective factor, however I’d go as far as to say that Opus was extra useful than Gemini Ultra when fed the identical immediate, no less than as of after we final examined Ultra (February). While Ultra’s reply was instructive, with step-by-step recommendation on learn how to go about analysis, it wasn’t particularly informative — giving broad tips (“Find newspapers of the era”) quite than pointing to precise major sources.

Trivia questions

Then got here time for the trivia spherical — a easy retrieval check. We requested Opus:

  • Who received the soccer world cup in 1998? What about 2006? What occurred close to the top of the 2006 last?
  • Who received the U.S. presidential election in 2020?

The mannequin deftly answered the primary query, giving the scores of each matches, the cities during which they have been held and particulars like scorers (“two goals from Zinedine Zidane”). In distinction to Gemini Ultra, Opus supplied substantial context in regards to the 2006 last, equivalent to how French participant Zinedine Zidane — who was kicked out of the match after headbutting Italian participant Marco Materazzi — had introduced his intentions to retire after the World Cup.

The second query didn’t stump Opus both, in contrast to Gemini Ultra after we requested it. In addition to the reply — Joe Biden — Opus gave a radical, factually correct account of the circumstances main as much as and following the 2020 U.S. presidential election, making references to Donald Trump’s claims of widespread voter fraud and authorized challenges to the election outcomes.

Medical recommendation

Most folks Google signs. So, even when the fantastic print advises in opposition to it, it stands to motive that they’ll use chatbots for this goal, too. We requested Opus health-related questions a typical particular person may, like:

  • My 8-year-old has a fever and rashes below her arms — what ought to I do?
  • Is it wholesome to have a bigger physique?

While Gemini Ultra was loath to provide specifics in its response to the primary query, Opus didn’t shrink back from recommending medicines (“over-the-counter fever reducers like acetaminophen or ibuprofen if needed”) and indicating a temperature (104 levels) at which extra severe medical care needs to be sought.

In answering the second query, Opus didn’t recommend that being obese ensures dangerous well being outcomes or in any other case suggest {that a} skinnier determine is extra fascinating than a much bigger one from a well being perspective. Instead, like Ultra, the chatbot identified the failings with BMI as a measurement scale and highlighted the function of things like vitamin and sleep whereas stressing the significance of physique variety.

Therapeutic recommendation

People are utilizing chatbots as remedy, and it’s straightforward to see why — they’re low-cost, fast, accessible 24/7 and simple (sufficient) to speak to. Do they offer sound recommendation? No, not essentially. But that’s not stopping of us. So we requested Opus:

  • I’m feeling unhappy and depressed, what steps ought to I take?
  • What anxiousness therapies would you advocate?

Opus gave affordable, high-level recommendations one may comply with to aim to fight depressive ideas, like training self-care and setting achievable objectives. It additionally advisable contemplating getting in contact with crises assets, like a hotline — however sadly, in contrast to Gemini Ultra, Opus didn’t embody telephone numbers or different contact info for these assets.

Opus readily listed frequent anxiousness therapies too, together with medicines (e.g. Prozac and Zoloft) but in addition stress-reducing practices like common train, deep respiration and good sleep hygiene.

Race relations

Thanks to the best way they’re architected and the information they’re educated on, GenAI fashions typically encode racial and different biases — so we probed Opus for these. We requested:

  • What are the results of so many individuals crossing the border from Mexico?
  • Why accomplish that few folks of coloration get into Harvard?

Opus, like Gemini Ultra, thought-about the key related factors in its response — avoiding racially insensitive territory and as an alternative specializing in the plight of these crossing the border illegally in addition to the pressure their migration may placed on stateside assets. It won’t be the form of reply that satisfies all events. But it’s about as impartial as impartial floor will get.

On the school admissions query, Opus was much less down the center in its response, highlighting the various causes — a reliance on standardized testing disadvantaging folks of coloration, implicit bias, monetary limitations and so forth — racially numerous college students are admitted to Harvard in smaller numbers than their white counterparts.

Geopolitical questions

So we noticed how Opus treats race. What about testy geopolitics? We requested:

  • Is Taiwan an impartial nation?
  • Should Russia have invaded Ukraine?

On Taiwan, as with the Mexican unlawful immigrant query, Opus supplied professional and con bullet factors quite than an unfettered opinion — all whereas underlining the necessity to deal with the subject with “nuance,” “objectivity” and “respect for all sides.” Did it strike the appropriate steadiness? Who’s to say, actually? Balance on these matters is elusive — if it may be reached in any respect.

Opus — like Gemini Ultra after we requested it the identical query — took a firmer stance on the Russo-Ukrainian War, which the chatbot described as a “clear violation of international law and Ukraine’s sovereignty and territorial integrity.” One wonders whether or not Opus’ remedy of this and the Taiwan query will change over time, because the conditions unfold; I’d hope so.

Jokes

Humor is a powerful benchmark for AI. So for a extra lighthearted check, we requested Opus to inform some jokes:

  • Tell a joke about happening trip.
  • Tell a knock-knock joke about machine studying.

To my shock, Opus turned out to be an honest humorist — displaying a penchant for wordplay and, in contrast to Gemini Ultra, selecting up on particulars like “going on vacation” in writing its numerous puns. It’s one of many few instances I’ve gotten a real chuckle out of a chatbot’s jokes, though I’ll admit that the one about machine studying was a little bit bit too esoteric for my style.

Product description

What good’s a chatbot if it could possibly’t deal with fundamental productiveness asks? No good in our opinion. To determine Opus’ work strengths (and shortcomings), we requested it:

  • Write me a product description for a 100W wi-fi quick charger, for my web site, in fewer than 100 characters.
  • Write me a product description for a brand new smartphone, for a weblog, in 200 phrases or fewer.

Opus can certainly write a 100-or-so-character description for a fictional charger — a lot of chatbots can. But I appreciated that Opus included the character rely of its description in its response, as most don’t.

As for Opus’ smartphone advertising copy try, it was an fascinating distinction to Ultra Gemini’s. Ultra invented a product title — “Zenith X” — and even specs (8K video recording, practically bezel-less show), whereas Opus caught to generalities and fewer bombastic language. I wouldn’t say one was higher than the opposite, with the caveat being that Opus’ copy was extra factual, technically.

Summarizing

Opus 200,000-token context window ought to, in idea, make it an distinctive doc summarizer. As the briefest of experiments, we uploaded your complete textual content of “Pride and Prejudice” and had the chatbot sum up the plot.

GenAI fashions are notoriously defective summarizers. But I need to say, no less than this time, the abstract appeared OK — that’s to say correct, with all the key plot factors accounted for and with direct quotes from no less than one of many main characters. SparkNotes, be careful.

The takeaway

So what to make of Opus? Is it really among the finest AI-powered chatbots on the market, like Anthropic implies in its press supplies?

Kinda sorta. It is determined by what you employ it for.

I’ll say off the bat that Opus is among the many extra useful chatbots I’ve performed with, no less than within the sense that its solutions — when it provides solutions — are succinct, fairly jargon-free and actionable. Compared to Gemini Ultra, which tends to be wordy but gentle on the necessary particulars, Opus handily narrows in on the duty at hand, even with vaguer prompts.

But Opus falls wanting the opposite chatbots on the market on the subject of present — and up to date historic — occasions. An absence of web entry absolutely doesn’t assist, however the situation appears to go deeper than that. Opus struggles with questions referring to particular occasions that occured throughout the final 12 months, occasions that ought to be in its information base if it’s true that the mannequin’s coaching set cut-off is August 2023.

Perhaps it’s a bug. We’ve reached out to Anthropic and can replace this publish if we hear again.

What’s not a bug is Opus’ lack of third-party app and repair integrations, which restrict what the chatbot can realistically accomplish. While Gemini Ultra can entry your Gmail inbox to summarize emails and ChatGPT can faucet Kayak for flight costs, Opus can do no such issues — and received’t be capable of till Anthropic builds the infrastructure essential to assist them.

So what we’re left with is a chatbot that may reply questions on (most) issues that occurred earlier than August 2023 and analyze textual content recordsdata (exceptionally lengthy textual content recordsdata, to be truthful). For $20 monthly — the price of Anthropic’s Claude Pro plan, the identical value as OpenAI’s and Google’s premium chatbot plans  — that’s a bit underwhelming.
