Pair a frontier model with a cheap sidekick to cut coding costs
Artificial Analysis benchmarked Cognition's Devin Fusion, which pairs a frontier model with the cheaper SWE-2 model as a sidekick. The GPT-6 Astra pairing costs 43 percent less and runs 31 percent faster than a Claude Fable 5.1 pairing while scoring close behind it.

Qwen3.8-27B now runs at Cerebras inference speed
Qwen3.8-27B is now served on Cerebras hardware for fast inference, with Artificial Analysis scoring it near GPT-5.6, DeepSeek V4 Pro, and Claude Sonnet 4.6, though early testers report it underperforms on coding tasks.
A dated brief from the vibe-coding frontier. Today’s Intel.
