imagine a swarm of Qwens reasoning together to deliver more accurate answers than one Qwen alone at a lower cost per task that’s already live on Fortytwo Engine
Introducing Fortytwo Engine An inference API that runs open-weight models through Swarm Inference • 7% higher scores on average vs. the base model • Nearly 25% fewer tokens per task • Same per-token price and speed • Private by default First model: Qwen3.8-27B Try it: engine.fortytwo.network

Fortytwo Engine more than doubled Qwen3.8-27B’s score on @scaling01's LisanBench Standalone BF16: 2,452 Fortytwo Engine swarm: 5,197 (+112%) LisanBench tests strategic planning, memory and constraint following: build the longest word chain possible using single-letter edits, dictionary words and no repeats. Both runs: 50 starting words × 3 trials, temperature 1.0, 100k-token cap, xhigh reasoning, leaderboard scoring. What improved: • Repetition loops observed in the standalone run; none observed on Engine • Higher mean scores on 40/50 starting words • Mean link validity: 92.2% → 97.1% • Fully valid chains: 5.6% → 22.9% of recorded answers • Answers after retries: 72/150 → 140/150 Against the October 16 leaderboard, these scores would place 28th → 14th, putting Qwen3.8-27B on Fortytwo Engine between GPT 5.4 (medium) and DeepSeek V3.2 Speciale. These are our runs, not official leaderboard entries.

The Liquid Inference router network is growing quickly. We now have 28 verified companies serving >1000 models, offering capacity dynamically and updating quotes in real-time. Average time for providers to onboard and integrate models is 3 hours, full verification within a day.

сapitalization-wise, these results are insane
We just updated Fortytwo Prime. Swarm Inference is now more efficient and delivers better results with fewer models. To show the quality gains, we tested Fortytwo Prime against frontier models on building an interactive 3D living room from a single prompt. Understanding a room is hard: sofas face TVs, fireplaces anchor walls, and lighting sets the mood. Results breakdown ↓
