A more powerful unrestricted version remains restricted to select access. Benchmarks are reportedly impressive. Pricing is noted as significantly higher than the already-costly Opus tier — roughly 2x. A notable mention is Stripe reportedly migrating 50 million lines of Ruby code in a single day using the model. The author raises concerns about cost and the broader implications of rapidly improving AI on the workforce. ## Full article daily.dev links to this article rather than hosting it.
