soo..... which is it? Mythos 5 or Fable 5?
They are not the same model, Mythos 5 is not yet available... so what are we doing here? taking the best score from both? Benchmark-maxxing hard, eh?...

Claude Code is literally unusable at the moment... this amount of write errors to disk is not okay... pls fix asap @claudeai@bcherny@trq212
oh - and if v2.1.159 is a fix, you need to say so, "Internal infrastructure improvements (no user-facing changes)" means nothing. You need to reprioritize a hotfix for this, plz.

First announcement signs of Claude Opus 4.8 - Embrace long-running tasks, hopefully /goal works better and opus 4.8 can set its own goals

Planning Mode Benchmarks from @bladnman says plan, but don't use "Plan Mode" π
1. Claude Code + Plan Mode: hurts, Opus β15.6, Sonnet β5.0.
2. GPT 5.4 + Cursor Plan Mode: also hurts, β11.1 drop vs no planning.
3. Cursor + Plan Mode: slight benefit for Anthropic models, Opus +1.5, Sonnet +0.5.
4. Opus 4.6 & Sonnet 4.6 have similar planning results (even with planning mode off).
5. Top result: GPT 5.4 + Codex CLI at 95.0 (X-High).
6. Gemini 3.1 Pro trails at 52β57.
