DeepSeek released an updated V4 Flash model on July 31 that jumped ten points to score 50 on the Artificial Analysis Intelligence Index, placing it one point behind OpenAI’s GPT-5.6 Luna while operating at roughly 60 percent lower cost per task (The Decoder).
Thinking Machines, the AI lab founded by former OpenAI CTO Mira Murati, released Inkling Small, an open-weights reasoning model less than one-third the size of its predecessor that outperforms the original on several coding and reasoning benchmarks (The Decoder). DeepSeek V4 Flash also received a new release checkpoint on July 31 (Simon Willison).
