<Update label="March 3, 2026">
  ## FLUX.2 \[pro] Speed Upgrade & Preview Endpoint

  FLUX.2 \[pro] is now approximately **2x faster** across both text-to-image and image editing — with no quality loss and no price change.

  * **\~2x faster generation** — Across text-to-image and image editing workloads
  * **No quality loss** — On par with the original across all benchmarks
  * **No price change** — Faster generation at the same price
  * **Same API contract** — Drop-in upgrade, no code changes required

  ### New: `flux-2-pro-preview` Endpoint

  We're introducing `flux-2-pro-preview`, where our latest FLUX.2 \[pro] improvements land first. This speed upgrade is available now on `flux-2-pro-preview`, and the endpoint will continue to be updated as we ship new capabilities.

  The existing `flux-2-pro` endpoint remains **unchanged** as a fixed snapshot for workflows that require reproducibility.

  Learn more in the [Preview Endpoint documentation](/flux_2/flux2_overview#preview-endpoints).
