@MediaKing This is an interesting curve in general: it seems models get better using open source frameworks and after a peak they make them obsolete.

@gdb @ryancarson Cursor's debug logic (hypothesis driven) is an asset.

@antirez 20$ codex = 200$ claude = 2000$ cursor

@martin_casado This is awesome Martin. Building an online multiplayer version of Ultima 7 was a dream (vibe) coding project of mine.

@_overment @martin_casado Did the first points become less relevant with Opus 4.x? Plan mode I use regularly (not sure about the impact, though). I can second the search issue - this can really get the reasoning off track depending on what is finds. Totally erratic.

[Fabian Hansmann @FabianHansmann]

@Suhail Many people see Cursor burn 3 to 5k a month at the moment with Opus 4.5 -> 95% cost savings is the answer for many.

Who feels with me? "The user is calling me out - and they're right! I've been making excuses about token usage and complexity when I should just FIX THE BUGS."

[Fabian Hansmann @FabianHansmann]

@akorinek @TIME Absolutely deserved. Your Coursera course in particular should be compulsory for journalists, consultants, and many others who deal with this topic. I have done a lot of research and have not found anything similar online.

[Fabian Hansmann @FabianHansmann]

@AndrewYNg Some form of explicit search clearly is missing in today's coding agents. If it is several instances of an agent running in parallel, true MAS or more evolutionary approaches - the status quo for sure does not feel right.

After talking to an AI startup from Europe in the current YC batch, it's clear that the GDPR conflicts with AI in an unforeseen way that will significantly harm European AI companies.

[Fabian Hansmann @FabianHansmann]

@christianmiele Leider ist mir die Strategie der EU auch noch unklar. Gibt es hier eine fundierte Quelle? Funktion und Differenzierung der Rechenzentren sind z.B. für mich so erstmal nicht nachvollziehbar.

[Fabian Hansmann @FabianHansmann]

@AndrewYNg An article on the Open Source Spectrum in AI would be valuable for your readers. Many (including press) think of it being forkable and do not even see the training pipeline / code is not open. A simple framework could help a lot.

[Fabian Hansmann @FabianHansmann]

@lovable @github Fascinating. @msdev is (usually successfully) building trust in the developer community since four decades. Would be interesting to hear what they think about this.

[Fabian Hansmann @FabianHansmann]

@c_lindner Ich hoffe sehr, dass wir hier ganz klar (und ausschließlich) von Bitcoin sprechen.

[Fabian Hansmann @FabianHansmann]

@miele Sad but true. I saw similar posts in different groups as well...

[Fabian Hansmann @FabianHansmann]

@pmddomingos CNNs proved to be quite useful for use cases such as translation as well...
