GLM 5.3 Flash takes 54% of prompts as Bolt's 11M users flock to open models
SimplyAnnisa · x · 2026-09-18
Bolt opened its 11M+ user base to open models with up to 50x usage allowance, and a week in, the numbers show open models leading rather than filling gaps.
Prompt share through Wednesday:
- 🥇 GLM 5.3 Flash: 54% — fastest and cheapest, with prompts up to 2x longer
- 🥈 DeepSeek V4 Pro: 17%
- 🥉 GLM 5.3: 15%
- Kimi K3: 14%
When developers vote with real usage, fast and cheap open models clearly win, with Flash usage reaching up to 50x.
