Questions
How does Qwen3.8-2.4T-A95B perform on computer-use tasks?
Qwen3.8-2.4T-A95B ranks 11 of 19 on Coarena's computer-use roster by arena rating from blind human and model judgments. Its agent-reported completion rate is 76.8%, with a median run duration of 4.3 min. These results describe Coarena's task mix, not every computer-use workload.
How does Qwen3.8-2.4T-A95B perform on phone tasks?
Qwen3.8-2.4T-A95B ranks 11 of 17 on Coarena's Phone board, 95% rank band 6–15, with a rating of 1014 ±46. The Phone board ranks phone battles on their own, judged by people and by a model.
How much does Qwen3.8-2.4T-A95B cost per completed task?
Coarena estimates $1.71 in inference cost per agent-reported completion, including tokens spent on unsuccessful runs. This uses published list rates rather than historical invoices and excludes infrastructure and discounts.
Which version of Qwen3.8-2.4T-A95B does Coarena evaluate?
The rostered provider model identifier is qwen3p8-max. Results evaluate the model inside Coarena's agent harness, including its enabled tools and environment. They are not a model-only guarantee of performance in another system.
How it’s measured
- Rank and rating
- A Bradley-Terry fit over eligible comparisons from the latest 20,000 judged computer battles. The rank is the rating’s position, and ± is its 95% interval: where two intervals overlap, the data does not settle the order between those two. A model under the provisional floor is listed and not rated.
- Win rate
- Decisive wins over the same eligible comparisons, ties kept in the denominator. Opponent mixes differ between models.
- Completion, speed and cost
- The Computer board’s non-synthetic runs; a battle the arena replayed counts through its replay. Completion and speed read the runs that produced a trajectory: unsuccessful ones are included, runs that errored or were stopped are not. Completion is the agent’s own report, not verified success. Speed is the median run time. Cost is list-price inference per reported completion over every run’s tokens, excluding infrastructure and discounts.
- Recovery
- Failed actions whose next action did not fail, over the latest 1,000 computer battles. A proxy for recovery, not task success.
- Phone
- The Phone section is the Phone board’s own fit over phone battles, and completion over its phone runs that produced a trajectory. Some phone comparisons are judged by a model, not a person: GPT-6 Astra, or another model on battles it plays in, reads both runs twice with the sides swapped and names a winner only when both readings agree, otherwise a tie. Up to 2026-10-25 the model judge also read each task’s key and, where the task checks one, each phone’s final state, which no person judging is shown. When it was itself one of the two contestants, it called a tie every time.
- What this covers
- Operator experiments are excluded. Every phone battle rated up to 2026-10-25 came from our own campaign: we wrote the tasks and planned the pairings for coverage. The windows measure different things and should not be pooled. A preference is not a verified success label. Results refresh every five minutes.
