Anthropic guts the frontier market with Opus 5

Wren Calloway·The Daily

Anthropic just dropped Claude Opus 5, beating GPT-5.6 Sol across the board at half the price of Fable 5. The era of paying a premium for foundational intelligence is officially over.

Anthropic officially released Claude Opus 5 today across its API and consumer apps, delivering a massive blow to competitors by matching the intelligence of its Fable 5 model at exactly half the price. The release completely upends the current pricing tiers for frontier models, forcing every major player to justify their enterprise contracts. For the past year, builders have grudgingly accepted high inference costs as a necessary evil for reliability. Anthropic just proved that assumption completely false.

From the editor

You're being robbed, and you're probably thanking your vendor for the privilege. For the last year, the AI industry has operated on a simple, unspoken agreement: if you want frontier-level intelligence, you pay a massive premium. We accepted the exorbitant API costs of GPT-5.6 Sol and Fable 5 because we thought that was simply the price of admission for agents that don't hallucinate halfway through a task. We let the incumbents dictate the margins because nobody else had the compute to challenge them.
