Claude Sonnet 5 Explained: 1M Context, $2/M Tokens & the Tokenizer Catch

From the creator

Link to our newsletter: https://bitbiased.ai/ Anthropic just made Claude Sonnet 5 the default model for everyone on Free and Pro — no popup, no email. So instead of taking the launch post at face value, I went through the system card, the pricing page, and the platform docs line by line. The benchmark gains are real. But there's a footnote about the tokenizer that quietly changes what "cheaper" means once the introductory pricing window closes in September. In this video: where Sonnet 5 lands next to Sonnet 4.6 and Opus 4.8, which benchmarks hold up and which need context, what the new effort parameter changes about how you prompt this model, and what Anthropic's own safety testing admits it still can't do as well as Opus 4.8. ⏱️ TIMESTAMPS 00:00 — Intro 1:46 — Where Sonnet 5 Lands In The Lineup 2:56 — What Actually Shipped? 4:54 — The Benchmark Numbers, Contextualized 7:01 — Effort And Adaptive Thinking: What Changed Under The Hood 8:37 — The Safety Picture: What Anthropic Tested And Admitted 10:54 — Who Should Actually Switch 11:53 — The Verdict 🔔 Subscribe for skepticism-first breakdowns of every major AI model release — I check the claims so you don't have to. 💬 If you've already migrated to Sonnet 5, what are you seeing on your own token costs?

Makers residency 4th edition

Your idea can be anything. At our last workshops, people built plant-based nutrition businesses, a way to measure planetary resilience, crochet headwear and a way to connect lonely people living in the same building. An asset manager went on to raise an additional £25M on their fund within nine months. The fourth workshop is a full day at KOKO with Nick Sarafa, learning to build with Claude Code. Bring the thing you keep meaning to start. We’ll bring the pizza.
