Open-source harness / Apache 2.0Recorded October 5–6, 2026
Then it hit level five, and Sage cost under three cents per kill.
SageCraft is the open-source harness that lets Sage, Levanto’s decision model, play World of Warcraft.
One real decision from the final session, at 15:17:21 UTC: from the screenshot Sage saw to the keys the harness pressed.
Each question comes with one image. This one holds the live game, plus close-ups of the selected target and of our own player frame.

Step 1 of 5: Screenshot
Sources: options, choices and level readings in the public excerpt . Frames, checks and hashes in the run record .
Session 1, October 5. The level-one dwarf selects a Ragged Young Wolf, casts Smite, and gets its first kill. The recorded Sage HUD shows the chosen actions as they happen.
Session 1 / level 1
One dwarf, one Ragged Young Wolf and a spell called Smite. Sage picked the action; SageCraft pressed the keys.
Session 26 / level 4
A Rockjaw Trogg took the dwarf down to about a quarter of its health. The harness offered two options, heal or “resources unclear”, and Sage took the heal. A few seconds later, health read 71%.
Session 26, October 6. A Rockjaw Trogg brings the dwarf down to roughly a quarter of its health. The Sage HUD shows SELF HEAL; health then reads 71%. The highlight edit adds an enlarged view of the recorded health bar.
Session 14, October 6. The dwarf is stuck in snowy branches while the HUD cycles through PROBE FORWARD, DETOUR BACKWARD LEFT and DETOUR FORWARD RIGHT. This clip does not show an escape.
Session 14 / level 4
Forward. Still a tree. Back and left. Still a tree. Knowing which way to go and actually getting there turned out to be different problems.
We stopped this session by hand.
Level five.
A very long way from that first wolf.
Session 32, October 6, about 15:17 UTC. The dwarf finishes a fight in Coldridge Valley, the level badge changes to 5 and the chat records the level-up. The highlight edit enlarges the recorded badge. Off-clip, at 15:17:56 and 15:17:57, Sage reads the badge twice and the harness stops the run.

Between sessions we made 16 harness fixes and locked the hunting area to the trogg hills once. We also recovered the character at least 8 times with the runner stopped, mostly with a desktop-automation agent, three of them resurrections. The last session ran with no human gameplay input, code changes or restarts: late level 4 to 5 in 18 min 5 s, with 11+ kills. It was one zone and one class, with nothing to compare against.

What Sage read
levanto-sage-v1.3 on every returned decision · median request time 0.8 sA game character picking its next move and a workflow picking its next step need the same thing: a decision model your software can ask.
SageCraft is open source under Apache 2.0. Run the tests, or replay the campaign’s last 42 seconds without a game or an API key.
Replay loads the recorded events into a local SQLite database and prints a summary. It doesn’t run WoW, call Sage or send any input to your computer.
You’ll need macOS, an English WoW client, a priest, a Sage API key and about an hour of calibration. A live run makes roughly 800–900 Sage calls per hour of active play.
Automated play may break the game’s terms of use and can get an account suspended. Only use an account you’re prepared to lose.
Your world doesn’t need wolves. Put Sage inside an agent, a workflow or a game of your own.
The harness is free. Sage calls count against your Levanto plan.
Sage is the AI model for agents: frontier-model judgment in milliseconds, with a calibrated confidence score to branch on.
