Yeah Sonnet 5 furthers the case. They stumbled on the next paradigm of training that is way beyond language modeling and the remaining lead is much less obvious.

Sonnet 5.0 just dropped. Early vibes > huge token guzzler, promotion pricing helps > step above 4.6, but not really as good as Opus 4.8 Opus 4.8 still seems better than Sonnet 5 in terms of cost/performance trade-off. Will confirm on LiveBench shortly

While this isn't the release we're waiting on from Anthropic (wen Fable!?) it's absolutely welcome! Sonnet 5 is here folks 🔥 It's more Agentic, it's faster than Opus 4.8 obviously while also being fairly close in performance!? [image]

BREAKING claude releases Sonnet 5. Here is what they didn't say. Opus 4.8 is completely nerfed into the ground since these benchmarks. almost unusable. this means Sonnet 5 will become the new standard moving forward until we get fable 5 back.

@claudeai Sonnet 5 climbed hard on agentic search. Huge implecations for agentic-workflow. The old Sonnet is basically dead weight on this point. [image]

It happened. Claude Sonnet 5 released. Dominates Opus 4.6. Almost as good as Opus 4.8. A fraction of the price. It's also significantly faster than Opus, while being incredibly agentic. Without a doubt the new go to model for Hermes/OpenClaw Do yourself a favor and do this [image…

Sonnet 5 also holds up better in agents that run unattended. It keeps state across many steps, recovers from errors without losing the thread, and checks its own work as it goes. More multi-step runs finish correctly the first time.

Claude Sonnet 5 is live. It does Opus-level work at Sonnet-level pricing. Sonnet jumps from 5.3% to 13.5% on @Zapier's AutomationBench, scoring more than double Sonnet 4.6 on multi-step workflows. It's got all the speed and none of the stalling. It trusts what it finds, knows [im…

Sonnet 5 is a substantial improvement over Sonnet 4.6 on reasoning, tool use, coding, and knowledge work. Its performance is close to Opus 4.8, at lower prices. [image]

Here is my first assessment of Sonnet 5: Sonnet 5 is better than Sonnet 4.6. Who would have thought? But jokes aside: Unfortunately, it is weaker than Opus 4.8 across all evals. Why they nevertheless labeled the latest Sonnet 5 iteration with a “5”, even though “4.8” would have […
