Watch out
Added on 2026-08-27 and priced on a promotion with a published end date — size a budget on the $0.15/$0.50 list rate, not the $0.075/$0.25 you will be billed until 2026-09-09. Open-weight status is not stated on the pricing page, so do not assume the rest of the GLM line's MIT terms carry over
What we would use it for
The cheapest tier in the GLM line while the launch promotion holds
What this has cost, week by week
Output price at each refresh since 2026-08-27. A vendor change is the provider changing its price. Our correction means this board changed what it prints and the provider's charge did not move — the two are never merged, because publishing the second as the first would be a price rise that never happened.
Nothing has moved since we started tracking it.
