Been using this for two days now. Notes below:
* This is an excellent alternative to Sonnet - which was my daily driver. I'm glad I tried GLM 4.5. You won't find any difference.
* My context usage per session was about 50% with Sonnet earlier, but it fills up fast with GLM, and I hit 80-90% often. Could be the lower context size that is hurting.
* Sonnet used to be very painful to work with as the context size goes beyond 80% (hence my habit of shorter conversations). GLM holds itself well even until the last bit of remaining context. Does not deviate from the assigned task.
