[AINews] Claude Opus 5: Fable-level performance at Opus price (half Fable)
Anthropic's Claude Opus 5 matches Fable performance at half the price
“Anthropic's Claude Opus 5 launch triggered a mix of benchmark scrutiny, strong anecdotal coding-agent praise, and renewed debate about frontier model evaluation.”
Anthropic released Claude Opus 5, which beats Fable on most official benchmarks while Anthropic's own messaging cautiously says it only 'comes close' — a gap attributed to the limits of current evals rather than actual capability. Independent evaluations confirm Opus 5 outperforms Fable, and at Opus pricing (half of Fable), it represents a significant efficiency milestone. On raw throughput efficiency it only matches GPT 5.6 Sol, keeping competitive pressure tight across the frontier.
