Google DeepMind's Andreas Kirsch argues open-source AI will soon match proprietary models like Mythos, drawing pushback from Florian Brand

Story Overview

In an X thread, Google DeepMind researcher Andreas Kirsch claims open-source models now unlock applications impossible with closed systems two years ago and projects they will soon reach the level of Anthropic's Mythos line; research engineer Florian Brand replies that such forecasts need concrete evidence rather than optimistic framing.

Not sure, but open-source is close behind and soon enough it will be as good as Mythos is now

The better question to predict the future is: are there examples that open source AI enables right now that weren't possible with closed models two years ago?

And the answer is of course yes ☺️

@BlackHC Are there any examples where open source AI enabled something that wasn’t possible with the closed models?

Open Question

Where the data stands right now

No benchmarks, datasets, or named use-case examples appear in the exchange to support the new-capabilities claim or the near-term parity projection, so the discussion rests on assertions whose timing remains unspecified.

Developer Impact

How the exchange shapes the wider debate

The back-and-forth highlights the recurring tension between forward-looking statements on open-source progress and demands for verifiable deltas, leaving participants to weigh the same projections without fresh technical anchors.

@BlackHC Looking at the actual evidence at hand and it’s looking awful for closed models in terms of safety. Closed guardrails don’t seem to work at all. Happy to discuss this later once i presented the facts.

yeah, looking further into this and it seems like open models are safer. blog about this later

@BlackHC I prefer evidence over vibes

@xeophon That's not vibes. That was a pretty good argument (better than yours imo)
