THE DAILY BRIEFING

Bittensor Daily — October 26, 2026

SN118 (Ditto)'s automated review system wrongly flagged roughly 30 legitimate agents under a new integrity rule, prompting the team to revert the rejections and revise the rule. Elsewhere, SN120 (Affine) saw a multi-hour training stall followed by a verified score improvement and the launch of a public video-generation studio, while SN44 (Score) moved against miners running multiple accounts from shared IP addresses.

Today's highlights

  1. 01

    SN118 (Ditto)'s automated review introduced an I2 integrity rule that wrongly flagged roughly 30 legitimate agents for context-compaction and retry behavior, which the team has since reverted while revising the rule.

    The error affected miner scoring directly, and the team's acknowledgment and correction shows how review-system bugs can misclassify valid work.

  2. 02

    SN120 (Affine) training stalled for about 4 hours after the e135 job exceeded its time limit, after which the following e136 checkpoint reached a held-out score of 0.875, up from 0.72 at e134.

    The team confirmed the stall left the checkpoint unchanged but doubled the time limit, and verified the subsequent score gain as genuine rather than a display bug.

  3. 03

    SN44 (Score) blacklisted several Cricket-track hotkeys after determining they were controlled by one miner using shared IP addresses and multiple account names.

    A community member raised similar concerns about multi-account control in the football track, suggesting the pattern may extend beyond the blacklisted hotkeys.

  4. 04

    A community member found files from a private evaluation dataset, marked for internal use and not to be distributed to miners, inside the public SN21 (AdTAO) repository since a Sep 2, 2026 commit.

    Public exposure of evaluation data could allow miners to game scoring, though the discoverer said the dataset was quarantined and not used.

  5. 05

    SN120 (Affine) launched Bittensor's first public AI video-generation studio along with a competition to optimize video generation efficiency.

    The launch extends Affine's work beyond internal training benchmarks into a user-facing product.

Subnet Community Pulse

SN15 24h +0.62%

ORO

What happened
Miners debated whether the current champion agent's code, including a regex pattern for text handling, constitutes prohibited hard-coding, with the dispute pending a decision from the subnet owner. Separately, the team clarified rules on resubmission after elimination and on scoring for agents whose hotkey is deregistered mid-race.
Community
Participants split between defending the champion agent's logic as generic text processing and arguing it amounts to hard-coding, with some calling for the owner to review the case. The exchange grew tense at points, with accusations of team affiliation and calls to keep the discussion respectful.
Official
A community member acting in a clarifying role confirmed that similarity checks still apply to eliminated agents resubmitted under a new hotkey, and that deregistered hotkeys continue to have their agents scored but require re-registration to receive emissions.

In debate · SN15 champion agent hard-coding dispute · 14 participants

  • Some miners argue the champion agent's code is generic text processing, not hard-coding, and passes the anti-cheating rule.

    “The code pass the cheating rule. This is not hard coding.”
  • Others reject this defense, saying the agent owner's own assurance is insufficient and the owner (seth) must rule on it.

    “your word alone is not enough to prove that the code for champion agent is clean. let’s wait to hear from the seth.”
  • Some insist plainly that any such logic is hard-coding regardless of how it is framed.

    “But hardcoding is hardcoding..”

SN118 24h +0.65%

Ditto

What happened
SN118 (Ditto)'s automated review introduced an I2 integrity rule that flagged context-compaction and retry behavior as a violation, wrongly rejecting roughly 30 legitimate agents. The team reverted the affected rejections and is revising the rule. Separately, users discovered a new 'Ditto Review' tool before it was officially announced, and the team acknowledged bugs causing reviews to stop early or return partial results. The team also clarified a case where an agent's copy-similarity hold was cleared after confirming it legitimately built on a publicly released model, with scores preserved.
Community
Users asked what was happening as agents were rejected and then reverted, with some reactions treating the episode lightly. A miner asked whether the reversal itself indicated a bug in the review process.
Official
The team acknowledged the I2 rule was applied too broadly, including to previously cleared agents, apologized, and said it was correcting the rule and clearing many rejections. It also confirmed a separate review-budget bug caused reviews to stop early and said this was fixed.

In debate · SN118 (Ditto) review bug fallout · 7 participants

  • Some community members reacted to the confusion with amusement rather than concern.

    “fun relif the stress”
  • The team acknowledged it had overreached by treating normal compaction and retry behavior as an integrity violation.

    “We treated losing previously seen evidence during a fallback as an I2 integrity violation. That rule was too broad”
  • A miner questioned whether the wave of rejections and reversals indicated a review bug, which the team said was instead a rule that was too narrow.

    “One hour ago, most top agents were rejected. but now they are reverted. Is that review bug?”

SN44 24h +0.17%

Score

What happened
SN44 (Score) blacklisted several Cricket-track hotkeys after determining they were controlled by a single miner using shared IP addresses and multiple account names. A community member also raised concerns about similar patterns of multiple accounts controlled by one miner in the football track. Separately, miners reported recurring ground-truth annotation errors across the petrol, person, PPE, vehicle, beverage and fallen-person tracks, prompting requests for manual review of specific blocks. A miner also asked the team to adjust the profile3 tie-break score threshold from 0.05 to 0.049, or to convert the petrol element to profile2, to avoid excluding top miners from emissions.
Community
Miners flagged specific blocks they believed were mislabeled in ground truth and asked for clarification on labeling policy for difficult images. Some miners who were blacklisted or lost scores due to errors such as HTTP 500 responses or missed latency failures asked the team to review their cases, and one miner questioned why vehicle detection had stopped working.
Official
The team confirmed removal of several blocks in the Petrol Station, Vehicle, PPE and Person tracks after review, stated that blacklisting decisions are not based solely on hotkey numbers, and declined the request to lower the tie-break threshold.

SN120 24h −1.10%

Affine

What happened
SN120 (Affine) training epochs stalled for about 4 hours after the e135 training job exceeded its 2-hour time limit; the job was closed without a model update, keeping the checkpoint at 4e4157b2, and the trainer's time limit was doubled. The following e136 checkpoint reached a held-out task score of 0.875, up from 0.72 at e134 and 0.56 for the base model. Separately, Affine (SN120) launched Bittensor's first public AI video-generation studio along with a competition to optimize video generation efficiency.
Community
Several miners flagged the stalled epochs and asked when training would resume. Miners have repeatedly asked the team to share the private UID ban logic, saying high-scoring miners are receiving no emissions despite high FLIP scores. A community member offered a technical explanation for a possible scoring bug, pointing to the epoch optimizer code and suggesting epochs with insufficient data should be dropped or deferred.
Official
The team explained the stall was caused by the e135 job running past its time limit due to long rollouts, confirmed the checkpoint was not updated, and said the trainer's time limit was doubled before e136 began collecting normally. The team also confirmed the 0.875 held-out score was a genuine result rather than a display bug, while noting the small task set (32) could cause a few points of variance between epochs.

SN21 24h +0.11%

AdTAO

What happened
A community member reported that the public repository ippcteam/SN21-adtao contained files labeled as a private evaluation dataset, including a manifest marked "PRIVATE — evaluation set, do NOT distribute to miners." The files were present in the repo since a commit dated Sep 2, 2026. The discoverer stated the dataset was quarantined and not used.
Community
Several community members questioned whether the exposed dataset had been used for mining and asked the team to address the matter directly. Some called for a review of the staking requirement for miners and asked for transparency on how any related proceeds would be handled.
