Setting Weights Too Fast
SettingWeightsTooFast is a documented Subtensor standard error. The standard-errors reference
defines it as “Exceeded rate limit for setting weights”
(Subtensor Standard Errors).
What It Means
This error means a validator attempted to submit weights again before the subnet’s required
weight-submission wait had elapsed. The weights-rate-limit reference defines WeightsRateLimit /
CommitmentRateLimit as how long, in blocks, a validator must wait between weight commits on a
subnet
(Subnet Hyperparameters: WeightsRateLimit / CommitmentRateLimit,
Subtensor Standard Errors).
So the rejection is about pacing repeated submissions, not about whether the validator had permission to set weights or whether the submitted weight vector was structurally valid (Subnet Hyperparameters: WeightsRateLimit / CommitmentRateLimit, Glossary: Weight Setting).
Why It Appears
The weights rate limit exists to bound how frequently a validator can change its on-chain weight signal. The hyperparameters reference describes it as the minimum block wait between one weight commit and the next on the same subnet (Subnet Hyperparameters: WeightsRateLimit / CommitmentRateLimit).
That makes SettingWeightsTooFast the narrow runtime error for retrying the set_weights path
before that wait requirement clears. It does not say the validator chose bad scores, and it does not
say the submission carried the wrong version metadata
(Subtensor Standard Errors,
Subnet Hyperparameters: WeightsRateLimit / CommitmentRateLimit).
What It Does Not Mean
This error should not be read as the version-compatibility failure on weight submission. Bittensor
documents IncorrectWeightVersionKey separately for the case where a set_weights call declares a
version below the subnet’s required weights version key
(Subtensor Standard Errors,
Subtensor Standard Errors).
It also should not be read as the weights rate limit parameter itself. WeightsRateLimit names the
underlying subnet rule, while SettingWeightsTooFast is the rejection label returned when that rule
is breached
(Subnet Hyperparameters: WeightsRateLimit / CommitmentRateLimit,
Subtensor Standard Errors).
Distinction from Weights Rate Limit
WeightsRateLimit / CommitmentRateLimit is the subnet hyperparameter that sets the required block
gap between weight commits. SettingWeightsTooFast is the runtime error returned when a validator
tries again before that gap has passed
(Subnet Hyperparameters: WeightsRateLimit / CommitmentRateLimit,
Subtensor Standard Errors).
- WeightsRateLimit / CommitmentRateLimit — required wait between weight commits.
- SettingWeightsTooFast — error returned when that wait is violated.
Distinction from Incorrect Weight Version Key
SettingWeightsTooFast is a pacing error on how soon another weight submission was attempted.
IncorrectWeightVersionKey is a compatibility error on the version metadata declared inside a
weight submission
(Subtensor Standard Errors,
Subtensor Standard Errors).
- SettingWeightsTooFast — submission retried too soon.
- IncorrectWeightVersionKey — submitted version is below the required version floor.
Reader Boundary
This page defines the meaning of the error label. It does not identify the live wait configured on
any particular subnet or tell a reader exactly when the next submission will succeed there. The
stable point here is narrower: if the required weight-commit gap has not elapsed, the chain rejects
the repeated submission with SettingWeightsTooFast
(Subnet Hyperparameters: WeightsRateLimit / CommitmentRateLimit).
