A repost of a benchmark-style comparison showing Claude Opus 5 beating Claude Fable 5 on a hard 3D coding task while costing only three-quarters as much.
- The quoted thread says Anthropic launched Claude Opus 5 and positions it as close to Fable 5-level frontier intelligence at half the price.
- In the reposted experiment, Opus 5 produced the best-engineered and most visually convincing Three.js output.
- The poster argues that Opus 5 also beats Fable 5 on most benchmarks, making Fable 5 harder to justify except for niche use cases.
- The comparison also mentions GPT-5.6 Sol and Kimi K3, but the main takeaway is the relative performance and price/value tradeoff between Anthropic’s models.
