On Thursday, Anthropic released Opus 4.8, the newest version of its most advanced publicly available model. The model is available everywhere, with standard pricing at the same level as the previous Opus release. The new model comes just 41 days after Opus 4.7 was released, a much faster upgrade cycle than normal for Anthropic. (The most recent Sonnet and Haiku models are three and seven months old, respectively.) The fast turnaround may have something to do with the chilly reception to Opus 4.7, which some users found disappointing. That interval has also seen significant new releases for OpenAI’s Codex and Google’s Gemini Flash model, increasing the pressure on Anthropic to keep pace.

Full report : Anthropic launches Opus 4.8, saying it’s “more likely to flag uncertainties about its work and less likely to make unsupported claims”, at the same price as 4.7.
