Anthropic just dropped Claude Opus 4.8 today, an incremental but meaningful upgrade over Opus 4.7. Here are the highlights: Model improvements Better performance across coding, agentic, reasoning, and knowledge work benchmarks Significantly improved honesty: the model is reportedly ~4x less likely to let flaws in its own code go unremarked compared to Opus 4.7 Alignment assessment shows lower rates of deceptive or misaligned behavior, on par with their Claude Mythos Preview model Scores 84% on Online-Mind2Web for computer use and browser agent tasks, ahead of both Opus 4.7 and GPT-5.5 New features launching alongside it Dynamic workflows (Claude Code): Claude can now spin up hundreds of parallel subagents in a single session to tackle large-scale problems like full codebase migrations. Available for Enterprise, Team, and Max plans. Effort control: Users on claude.ai can now choose how much compute effort Claude puts into a response, from faster/cheaper to deeper/slower. API update: The Messages API now accepts system entries inside the messages array, letting developers update instructions mid-task without breaking prompt cache. Pricing Same as Opus 4.7: $5/M input tokens, $25/M output tokens. Fast mode (2.5x speed) is now 3x cheaper than it was for previous models, at $10/$50 per million tokens. What's next Anthropic mentioned they are working on bringing Mythos-class models (currently in limited preview for cybersecurity use cases under Project Glasswing) to general availability in the coming weeks.

According to Anthropic, it trains "all [its] models to be honest - for instance, to avoid making claims that they can't support." But it notes that "a general problem with AI models is that they sometimes jump to conclusions, […]

The US military has long known that cheap fixes could stop location data from exposing its troops. It adopted almost none—and now says adversaries are using the data to target soldiers during a war.

I want to create a website in a couple of days. It's main purpose is to offer a free digital download. I want to capture email in the process, to provide follow-up guidance to using the product. There's no e-commerce involved and few pages (4-5). Analytics and domain registration would be a bonus. I want it to look nice - I'd like to have flexible visual design options or be able to adapt a template. I'm comfortable with the likes of WordPress, Wix, Squarespace, Shopify, Canva but not so much using code. In this situation, what would people recommend? 🙏 submitted by /u/jahwinnie [link] [留言]
