AICodeKing reports that SWE-2 scored 67 out of 80, or 83.75%, across eight KingBench 3 coding tasksCode generation uses AI or another automated system to create source code from instructions, examples, schemas, or higher-level specifications.. That narrowly beat DeepSeek V4.1 Flash in the same run and placed SWE-2 fifth on the channel's current leaderboard, above Fable 5 but behind GPT-6 Astra.
The test spans interactive simulations, 3D objects, SVG generation, a game, a maths problem and a connected task that creates training data, fine-tunes a modelFine-tuning continues training a model on selected data so its behavior becomes better suited to a task, domain or operating environment. and serves it through a local web interface. SWE-2 earned full marks on the maths and fine-tuning tasks, while DeepSeek V4.1 Flash performed better on the game and 3D wristwatch tasks.
AICodeKing also found SWE-2 effective on longer agent work and a terminal-based movie tracker. Its main weakness was repeated clarification questions, so the suggested workaround is a system instruction that permits one essential question, encourages reasonable assumptions for routine choices and asks the model to continue toward a complete result.
