Agent Stack Daily covers the return of Claude Fable 5: US restrictions on Anthropic's Mythos and Fable models were dropped on June 30, and the Mythos-class flagship is back on OpenRouter with 1M context, multimodal input, and reasoning support. OpenClaw v2026.6.11 and OpenAI Codex rust-v0.142.5 shipped, and Claude Sonnet 5 hit OpenRouter with 1M context alongside Google's Nano Banana 2 Lite. Research includes the Orca unified world latent space paper, the Agents-A1 35B MoE, BlockPilot on diffusion speculative decoding, generative skill composition, and TRIAGE on role-typed credit assignment. OmniRoute consolidates 231 providers behind one endpoint. Show notes: https://tobyonfitnesstech.com/podcasts/episode-78/
