Bolt's 11M builders pick GLM 5.3 Flash: 54% of open model usage in week one
HeyAmit_ · x · 2026-09-18
Bolt gave its 11M+ builders access to multiple open models with up to 50x usage, and early numbers are telling: GLM 5.3 Flash leads with 54% of usage, followed by DeepSeek V4 Pro (17%), GLM 5.3 (15%), and Kimi K3 (14%).
The winner is the fastest, cheapest option, with support for prompts up to 2x larger. The takeaway: benchmarks show what models can do, but real-world usage shows what builders actually choose — and speed plus price beat leaderboard scores.
