On coding performance alone, a 763B model handed out under MIT drew level with the summit — DeepSeek V4.1-Flash-1017 edged out Opus 5 and GPT-5.6 Sol on the SWE benchmark
On October 17, DeepSeek released V4.1-Flash-1017, an MIT-licensed open-weight model. It scored 77.0 on DeepSWE v1.1, the coding benchmark, edging out Opus 5 and GPT-5.6 Sol on that single point. You can self-host it or use a cheap API, but it still trails on general reasoning like HLE — and "silentl
