GPT-6 Pro seems to underperform astra max right now?

Anecdata model ranking on large scale software project planning:

Opus 5.5: originality, overall knowledge
Astra: getting the details right
@grok 4.7: clearest writing/thinking

IMO Grok also outperforms on faster iteration/experimentation (esp. managing resources in autoresearch loops), even if it's less knowledgable right now on many subfields โ€“ I expect Grok to move up the ranks fast.

Introducing Magnetar from Microsoft Research, the first zkVM that is: (1) general-purpose (RV64), (2) post-quantum from standard hashes alone (no curves, no lattices, no Poseidon), and (3) built for recursion.

Despite its conservative security, it is the fastest zkVM: 7.2โ€“8.7 MHz on a laptop, 10โ€“39ร— faster than existing zkVMs across 15 workloads! An optimized version reaches 9.5โ€“12.8 MHz.

๐Ÿ’ฏ Still plenty of work to do, but it can and must be done. Beyond the UX gains, all Satoshi-derived nodes will continue to require security hardening this year, and spreading out confirmed throughput by 10ร— would meaningfully harden node security and tx censorship resistance.
