GLM Coding Plan (Z.ai)
$18 (Lite) / ~$80 / ~$168 per mo (quarterly/yearly discounts)
Models: GLM only (GLM-5.3 flagship + GLM-5.3-Flash; requests for 5.2/5.1 auto-route to 5.3, 4.7 to 5.3-Flash)
What "flat" means: Fixed price with dual-window credit quotas: 2,000 / 12,000 / 28,000 credits per 5 hours and 10,000 / 60,000 / 140,000 per week (Lite/Pro/Max).
The catch: Credits, not prompt counts, since the 2026 revamp — burn varies by model, so capacity is less legible than a request cap. GLM models only; only the $18 Lite price is pinned on official docs, so confirm Pro/Max at checkout.
Pick GLM Coding Plan (Z.ai) when
+GLM-5.3-class quality covers your coding work
+You want a cheap flat plan and your volume fits the credit windows

OpenCode Go
$10/mo ($5 first month)
Models: 12 open-weight (DeepSeek V4, Qwen 3.6, GLM 5.2, MiniMax M3…)
What "flat" means: Fixed price buying ~6x its value: ~$60/mo of usage-equivalent, metered at model rates.
The catch: A capped value multiplier with tight windows: $12 per 5 hours, $30 per week, $60 per month. Open-weight models only.
Pick OpenCode Go when
+You run open-weight models and want the best raw value multiple available (~6x)
+Your usage fits inside $30/week — moderate, not always-on
+You want a plan built by OpenCode that also works with Hermes and OpenClaw
