He argues that the "frontier" of open-weight models has already outgrown the closed-source camp:
- Models like DeepSeek v4 Pro and Kimi K3 are released as open weights with massive parameter scales.
- In contrast, Claude Fable 5 and GPT-5.6 Sol remain closed-source, with the latter only available to government-approved clients.
- He concludes that the visible boundaries of open-weight models have already surpassed closed-source ones, making it worth watching if "closed" will gradually become synonymous with "lagging behind" in the future.
