NVIDIA released gpt-oss-puzzle-88B on March 26, 2026, a 88-billion parameter mixture-of-experts model optimized for inference efficiency on H100 hardware. Built using the Puzzle post-training neural architecture search framework, the model achieves 1.63× throughput improvement in long-context (64K/64K) scenarios and up to 2.82× improvement on single H100 GPUs compared to its parent gpt-oss-120B, while matching or exceeding accuracy across reasoning effort levels.

DuckDuckGo's Duck.ai chatbot platform now includes OpenAI's GPT-5 mini for free users and GPT-5.2 for subscribers, both with reasoning capabilities. The platform continues to anonymize all conversations by default, stripping metadata before routing chats to model providers including Anthropic, Meta, Mistral, and OpenAI.

A new Bytedance study reveals that large reasoning models actually know when they've reached the correct answer, but common sampling methods prevent them from stopping. The models engage in unnecessary cross-checking and reformulation despite already solving problems correctly.
