DeepSeek’s Flash ties Anthropic’s Opus 5.5 in AI browsing benchmark

DeepSeek ’s latest AI model, Flash, has achieved a score of 75 out of 100 on the long-horizon browsing benchmark from Browser Use, equaling the performance of Anthropic ’s Opus 5.5. This development marks a significant milestone for DeepSeek as it places its V4.1 Flash model in direct competition with Anthropic’s latest offering. The benchmark result suggests an intensifying competition in the AI model landscape, particularly in browser-agent tasks where both companies are vying for prominence. This tie occurs despite the current Browser Use Bench chart listing DeepSeek’s model at a slightly lower score than Opus 5.5. Observers will be closely monitoring any updates to the Browser Use benchmark that reflect the tie between DeepSeek and Anthropic.
