DeepSeek V4.1 Flash launches; GPT-6.1 Astra said to be on hold
DeepSeek released V4.1-Flash-1017, claiming parity with Claude Opus 5.5 and beating GPT-5.6 Sol on most coding and agent benchmarks, while noting GPT-6.1 Astra is reportedly on hold after falling short in internal safety testing.
DeepSeek just released its most advanced model yet: DeepSeek-V4.1-Flash-1017. The company's own benchmarks put it roughly on par with Claude Opus 5.5, a significant jump over the regular V4.1 Flash. It beats GLM-5.3, and even GPT-5.6 Sol, on most coding and agent benchmarks! With GLM-5.5 and Qwen 4 also expected soon, we can safely say China is back. Expect a response from the United States, with all eyes on Anthropic and the rumored Fable 5.5. Meanwhile, no new frontier model from OpenAI. GPT-6.1 Astra is on hold after falling short in internal safety testing. Open Source vs Closed Source rematch?
