Dev swaps prod system from GPT-5.4 to GLM: faster, cheaper, far more reliable

ivanbezdomny says his team switched a production system from GPT-5.4 (5.5 and 5.6 were less reliable) to GLM and GLM-flash plus Jev and a custom finetune — faster, cheaper and much more reliable. He still likes Astra and Claude for coding but finds them too expensive and unreliable for prod, arguing big labs' smaller/cheaper/older models no longer match open weights. A write-up is coming.
