Opus 5.5 is proof that we do need smarter models

Theo - t3․gg — Tue, 20 Oct 2026 22:13:42 +0000

As we see games get full blown crossovers and models get incredible at optimizing things on their own, I'm not sure we actually NEED smarter models?

Does the $200 Codex plan suck now?

Theo - t3․gg — Wed, 7 Oct 2026 20:40:02 +0000

OpenAI's $500 plan's new Ultrafast mode means your weekly limit can disappear in 2 hours, so does that just mean the $200 tier is useless now? Thank you Browserbase & General Translation for sponsoring! Browserbase:…

Theo - t3․gg — Tue, 6 Oct 2026 12:40:33 +0000

Your ability to work and put out even bigger things is only limited by your token usage, so lets fix that - it's time to learn how to token-max.

Anthropic Actually Fixed Opus

Theo - t3․gg — Wed, 23 Sep 2026 17:03:05 +0000

After Opus 5 wrecked my codebases, Opus 5.5 got a full day of real work done on about 20% of my weekly Claude limit, and I'm finally not scared to merge what it writes.

Jev is a brand new Typesafe model that's a fast classifier with tons of perks and safety, but it doesn't replace reasoning models like Astra/Fable.
