Opus 5.5: Claude Just Hit Back at ChatGPT

Anthropic's Opus 5.5 reset the AI model leaderboard on price and quality, but the lead among OpenAI and Anthropic flips every few weeks.

• Opus 5.5 leads: Anthropic's new model beats Fable 5.1 and GPT-6 Astra on most benchmarks while running ~40% cheaper than prior Opus, per Gael's token usage test.
• Token economics flipped: Gael ran Cloud Code for 2.5 hours on the $20 plan using only 8% of his weekly limit, versus Astra burning a $20 plan in 30-40 minutes.
