> Letting anyone download and run powerful AI models has real risks. But closed-only AI would concentrate power in a handful of companies, and that is a risk too.

Few debates in AI are as heated as the one about open weights: whether companies should publish their trained models for anyone to download, inspect and modify. One side sees a public good; the other sees a loaded weapon left on the kitchen table. Both have a point. On balance, I think openness is winning the argument, with conditions.

## The case for

**Science:** researchers cannot study what they cannot access. Much of what we know about how language models work, and fail, comes from open models.

**Competition:** open models keep prices down and stop a few companies from controlling the platform everyone builds on.

**Privacy and sovereignty:** hospitals, governments and companies can run open models on their own machines, without sending sensitive data to someone else’s cloud.

**Everyone else:** developers in countries and languages the big labs overlook can adapt models for their own needs.

## The case against

Once weights are published, they cannot be recalled. Safety training can be stripped out by fine-tuning, and a determined bad actor can use an open model without any company watching. For today’s models, the extra harm is debated; for future models with serious capabilities in areas like biology or cyber-attacks, the stakes would be higher.

## A middle path

The sensible position is not “open everything” or “close everything”, but to test models carefully before release and to be more cautious as capabilities rise. Most models today are well on the safe side of that line, and the benefits of opening them are real. If that changes, the policy should change with it.
