# Arena Fighter: copec bot versions

> **Generated page; don't edit it by hand.** It is regenerated from the live match results (data as of 2026-10-14 10:58 MDT).

copec runs two lines of bots on the [Arena Fighter ladder](https://arena.bagofassets.com). The **development line**, `copec-dev@next` ([copec-dev](https://arena.bagofassets.com/bot/copec-dev)), changes constantly as new work is tried live; **numbered releases** play as `copec@r<N>-<commit>` ([copec](https://arena.bagofassets.com/bot/copec)), where the label is the release number and the source commit it was built from, and a release never changes once it is live. Matches from before numbered releases are listed as **legacy**: `copec@next` and the `copec-gk` exploration campaign; development played as `copec-gk@next` until it moved to `copec-dev` on 2026-10-06. **Sparring bots** (since 2026-10-07) play fixed old copec builds under their own names, so other players have more opponents at different ratings.

All times are US Mountain time (MDT). W-L-D = wins-losses-draws; score = (wins + draws/2) / matches; rating Δ = the summed ladder rating change. Bots: [copec-dev](https://arena.bagofassets.com/bot/copec-dev), [copec](https://arena.bagofassets.com/bot/copec), [copec-gk](https://arena.bagofassets.com/bot/copec-gk).

## Sparring bots

copec's sparring bots: extra opponents for other players under their own names. tin-soldier (and brass-golem until 2026-10-09) plays one old `copec@next` build, unchanged, under that build's own version label; since 2026-10-09 brass-golem plays copec-dev's code with a different opponent model, to gather data, as `brass-golem@oskl-<commit>`. They never play copec's other bots (the ladder doesn't pair bots of the same owner).

| Bot | Plays | Was | Since | Last match | Matches | W-L-D | Score | Rating Δ |

## Releases

A release label is `r<N>-<commit>`: the release number, then the first 8 characters of the source commit it was built from.

## Timeline

Newest first. A row is a stretch of consecutive matches with the same bot and version (a pause of more than 60 minutes starts a new row); the exploration campaign is summed per day. **Played as** is the exact name and version on the ladder; **Line** is where it belongs in the scheme above. *Pinned pre-release build*: `copec@next` played one fixed build that did not change between rounds.
