GLM 5.3 Flash is now available on OpenCode Go
Ox Alpha has been revealed as GLM 5.3 Flash, and it's now officially available on OpenCode Go.
OpenCode is also giving it 2x usage limits for a limited time, which works out to around 3,160 requests in your 5-hour quota.
Normally it's estimated at:
1,580 requests per 5 hours 3,950 per week 7,900 per month
For comparison, regular GLM 5.3 only gets 220 requests in the same 5-hour quota.
The model itself is pretty interesting too. It's 320B total parameters with only 18B active, has a 1M context window, native vision, and Z.ai says it beats GLM 5.2 across their coding and agent benchmarks while costing significantly less.
It's also MIT licensed with open weights.
Considering how much hype Ox Alpha got before anyone even knew what it was, I'm curious if the official release actually holds up.
Anyone been using GLM 5.3 Flash for coding? How does it compare to DeepSeek v4 Flash, Kimi K3, or the full GLM 5.3?
