Matt Shumer, co-founder and CEO of OthersideAI, often known as its signature AI assistant writing product HyperWrite, has damaged his close to two days of silence after being accused of fraud when third-party researchers have been unable to duplicate the supposed high efficiency of a brand new giant language mannequin (LLM) he launched on Thursday, September 5.
On his account on the social community X, Shumer apologized and claimed he “Obtained forward of himself,” including “I do know that a lot of you might be excited concerning the potential for this and are actually skeptical.”
Nevertheless, his newest statements don’t totally clarify why his mannequin, Reflection 70B, which he claimed to be a variant of Meta’s Llama 3.1 skilled utilizing artificial information technology platform Glaive AI, has not carried out in addition to he initially acknowledged in all subsequent unbiased checks. Nor has Shumer clarified exactly what went unsuitable. Right here’s a timeline:
Thursday, Sept. 5, 2024: Preliminary lofty claims of Reflection 70B’s superior efficiency on benchmarks
In case you’re simply catching up, final week, Shumer launched Reflection 70B, on the open supply AI neighborhood Hugging Face, calling it “the world’s high open-source mannequin” in a submit on X and posting a chart of what he stated have been its state-of-the-art outcomes on third-party benchmarks.
Shumer claimed the spectacular efficiency was achieved to a way known as “Reflection Tuning,” which permits the mannequin to evaluate and refine its responses for correctness earlier than outputting them to customers.
VentureBeat interviewed Shumer and accepted his benchmarks as he introduced them, crediting them to him, as we should not have the time nor sources with which to run our personal unbiased benchmarking — and most mannequin suppliers we’ve coated have to this point been forthright.
Fri. Sept. 6-Monday Sept. 9: Third social gathering evaluations fail to breed Reflection 70B’s spectacular outcomes — Shumer accused of fraud
Nevertheless, simply days after its debut and over final weekend, unbiased third-party evaluators and members of the open supply AI neighborhood posting on Reddit and Hacker Information started questioning the mannequin’s efficiency and have been unable to duplicate it on their very own. Some even discovered responses and information indicating the mannequin was associated to — maybe merely a skinny “wrapper” — pointing again to Anthropic’s Claude 3.5 Sonnet mannequin.
Criticism mounted after Synthetic Evaluation, an unbiased AI analysis group, posted on X that its checks of Reflection 70B yielded considerably decrease scores than initially claimed by HyperWrite.
Additionally, Shumer was discovered to be invested in Glaive, the AI startup he stated whose artificial information he used to coach the mannequin on, which he didn’t disclose when releasing Reflection 70B.
Shumer attributed the discrepancies to points through the mannequin’s add course of to Hugging Face and promised to appropriate the mannequin weights final week, however has but to take action.
One X person, Shin Megami Boson, overtly accused Shumer of “fraud within the AI analysis neighborhood” on Sunday, September 8. Shumer didn’t immediately reply to this accusation.
After posting and reposting varied X messages associated to Reflection 70B, Shumer went silent on Sunday night and didn’t reply to VentureBeat’s request for feedback — nor submit any public X posts — till this night of Tuesday, September 10.
Moreover, AI researchers akin to Nvidia’s Jim Fan identified it was simple to coach even much less highly effective (decrease parameter, or complexity) fashions to carry out nicely on third-party benchmarks.
Tuesday, Sept. 10: Shumer responds and apologizes — however doesn’t clarify discrepancies
Shumer lastly launched an announcement on X tonight at 5:30 pm ET apologizing and stating, partially, “we have now a staff working tirelessly to know what occurred and can decide proceed as soon as we resolve it.

Shumer additionally linked to a different X submit by Sahil Chaudhary, founding father of Glaive AI, the platform Shumer beforehand claimed was used to generate artificial information to coach Reflection 70B.
Intriguingly, Chaudhary’s submit acknowledged that a few of the responses from Reflection 70B saying it was a variant of Anthropic’s Claude are additionally nonetheless a thriller to him. He additionally admitted that “the benchmark scores I shared with Matt haven’t been reproducible to this point.” Learn his full submit beneath:
Nevertheless, Shumer and Chaudhary’s responses weren’t sufficient to mollify skeptics and critics, together with Yuchen Jin, co-founder and chief know-how officer (CTO) of Hyperbolic Labs, an open entry AI cloud supplier.
Jin wrote a prolonged submit on X detailing how arduous he labored to host a model of Reflection 70B on his web site and troubleshoot the supposed errors, noting that “I used to be emotionally broken by this as a result of we spent a lot time and power on it, so I tweeted about what my faces appeared like through the weekend.”
