Why your arena fighter is benched as beta
A rating that comes back too low benches the fighter, but you can re-upload.
The short answer
Beta means your arena fighter is benched. When the rating on your entry photo comes back too low, the fighter is marked beta and cannot fight. It is not a ban and it is not permanent: you can re-upload a photo and try again.
What the status actually is
The Arena rates your entry photo once, and that rating is your fighter. If the result falls too low, the fighter does not go active. Instead it is marked beta, and the fight button stays unavailable.
The site does not publish the cut-off, so this page does not guess one. What matters for you is the effect: a beta fighter cannot be matched, whatever your Coin balance is, because the problem is the fighter and not the stake.
Why a low rating is often a photo problem
A low result does not always mean the subject of the photo is the issue. It often means the photo gave the rating little to work with: harsh shadows, a blurred frame, an awkward angle or heavy cropping all pull a score around.
The lighting and angle checklist lists what to fix before another attempt. The same subject photographed in even light and held steady can read very differently from a rushed shot.
How to try again
The route out is the one the Arena already offers. Re-upload a photo, let it be rated, and wait for the window to poll the result. If the new rating clears the bar, the fighter goes active and the fight button unlocks as normal.
Take the new photo before you start, rather than during the upload. Change one thing at a time, ideally the light first, so that if the score moves you know why.
Expect the second score to differ
A new photo can score differently, and that is normal rather than a fault. Why your AI cock score changed between photos walks through the reasons a number moves, so a different result the second time is no cause for alarm.
Equally, do not count on a lucky retake. The rating responds to the picture, so a better picture is the lever you have.
How to tell a photo problem from bad luck
Look at the photo you uploaded with fresh eyes. If it is dim, soft or tilted, the likely culprit is the picture. If it looked good by every check on the list, a second upload costs little, and it is a fair way to find out whether the first result was a one-off.
Keep both photos. Comparing a failed attempt with a better one is the quickest way to learn which change moved the score, and it makes the next entry easier.
What not to do
Do not take a string of near-identical photos and upload them one after another hoping one slips through. If the first failed for a reason such as harsh light or a soft focus, the next one will fail for the same reason. Fix the cause first, then upload.
And do not read a beta flag as a verdict on you. It describes one photo, rated once, at one moment. It tells you how that picture scored, and a better picture is a new input.
While you are benched
Being benched stops you fighting, nothing more, and the rest of the site works as usual. Come back to the Arena when you have a better photo, and treat the first attempt as a lesson in what the rating responds to.
