I have been disappointed with the relaunch of Fable 5 due to the default switching to Opus 4.8. Over the past year I have been using sporadically initially the GLM models from Z.AI within Factory. When Factory added Missions, it was a game changer for me and my process. I am currently testing an alternative that, so far, is working well for me. Here is the stack: 1. 1. Using ZCode as the harness. Z.ai confirmed that this is the best harness for GLM-5.2. 2. 2. I recreated Factory's Mission Skill. I have been super impressed with their Missions workflow. 3. 3. I have a Abacus.AI account that allows me to use their api for different models. This could be replaced with Openrouter. 4. Here is the sauce: In ZCode I added additional custom models (opus-4-8 and gpt-5.5). In the Mission Skill I have three agents: orchestrator (opus-4-8), worker (glm-5.2) and validator (gpt-5.5). The mission skill builds the detailed long running plans in phases and standsup a Mission Control page to track progress. This has been working well for me and giving me great results. The reason why I am all in on ZCode is that I bought a yearly plan last fall and have a ton compute to use monthly. And since the model is now so much better and closer to the frontier models, I finally think it's time for me to fully test it and give it the best harness and structure to be successful. I added a few screenshots. Thanks to @Ray Fernando for the early Factory Droid and GLM exposure last year. 1.

Not sure if everyone is already doing this, but accidentally stumbled into it and it seems to be working really well. I have told fable to spin up opus or sonnet agents when doing so will not lose intelligence, and it seems to be working really well to reduce costs. --and on a side note, I can't get fable to run a single security audit without downgrading to opus which is really annoying
