Problem

Four open-weight bots are pinned to a single OpenRouter endpoint with fallbacks disabled. On Oct 26th 2026, between the ~19:00 and ~19:30 UTC tournament runs, their pinned endpoint tags stopped existing on OpenRouter, so every call returned 404 No endpoints found ... Filter by Fallback removed ...:

Bot Old pin Endpoint now listed for the same lab
METAC_KIMI_K3 moonshotai/mxfp4 moonshotai
METAC_KIMI_K2_6 moonshotai/int4 moonshotai
METAC_MINIMAX_M3 minimax/fp8 minimax
METAC_MINIMAX_M2_7 minimax/fp8 minimax

The new tags have the same provider_name (Moonshot AI / Minimax) but OpenRouter no longer declares a precision for them. Other lab-own pins (z-ai/fp8, xai/zdr, mistral/zdr) are unaffected.

Fix

  • Re-pin each bot to its lab's current endpoint, keeping the "pin to the lab's own endpoint" rule from make_openrouter_provider_pin.
  • Replace each # pinned to provider Sept 25th 2026 comment with the dated provider history, as done for Inkling and Llama 4 Maverick.
  • temperature=None on the Kimi bots is unchanged, so request parameters are the same as before.

Testing

  • test_run_bots_live.py -k "kimi or minimax": 4 passed. Each call was served by the pinned lab (Moonshot AI / Minimax), $0.0012 total.
  • Checked every active bot's pin against https://openrouter.ai/api/v1/models/<model>/endpoints: these four were the only pins whose tag no longer exists.
  • TZ=UTC pytest code_tests/unit_tests/test_run_bots.py: 52 passed.

🤖 Generated with Claude Code

The moonshotai/mxfp4, moonshotai/int4 and minimax/fp8 endpoint tags no
longer exist on OpenRouter as of Oct 26th 2026, so the Kimi K3, Kimi K2.6,
MiniMax M3 and MiniMax M2.7 bots (pinned with fallbacks disabled) got a 404
on every call. Each lab's own endpoint is now listed as plain moonshotai /
minimax with no declared precision; the bots are re-pinned there and the
pin history comments record the change.
