Episode 70: Qwen 3.6 27B Hits 80 t/s on Mixed RTX Hardware, Codex Opens to OSS, Fable 5 Suspended

A heterogeneous dual-GPU setup running an RTX 5080 paired with an RTX 3090 sustained 80 tokens per second on Qwen 3.6 27B at Q8 quantization with a clean tensor-parallel layer split. OpenAI opened Codex to open source maintainers and added three workflow courses in OpenAI Academy. Anthropic suspended Fable 5 and Mythos 5 from US government access following a federal directive tied to the Amazon CEO's meetings with Trump administration officials. Endor Labs placed Fable 5's coding results mid-tier, and developers debated Claude Fable's proactive agent behavior. Show notes: https://tobyonfitnesstech.com/podcasts/episode-70/
