'Opus 5.5 benchmarks just dropped'

BridgeMind claims Opus 5.5 beats Fable 5.1 and GPT-6 Astra 'across the board' at half Fable 5.1's price. This overstates Anthropic's own claim ('matches Fable 5.1 on most tasks'); treat as hype, not a source for benchmark numbers.

OPUS 5.5 BENCHMARKS JUST DROPPED.

It beats Fable 5.1 and GPT 6 Astra across the board.

Agentic coding, knowledge work, reasoning, computer use, visual recognition. Opus 5.5 leads every single one.

At half the price of Fable 5.1.

Anthropic finally shipped the model we have been begging for. Smart enough to lead the frontier and affordable enough to actually use.

Testing it now.
