Could "claude-jupiter" be Anthropic’s next Sonnet-class model? Sonnet 4.8 surfaced in the Claude Code source leak alongside Opus 4.7 and the Mythos/Capybara references — so this might be another internal codename rather than a random Discord rumor.

GPT-5.5: Smartest model but most confidently wrong benchmark results reveal flaw
By
–
GPT-5.5 is the smartest model ever tested. It's also the most confidently wrong. That's not an opinion. That's what the benchmarks say when you read both columns. Artificial Analysis runs AA-Omniscience, a benchmark designed to penalize models that guess instead of saying "I

Agentic Harness Boosts Coding Agents 10% Without Model Changes
By
–
You can now make coding agents 10% smarter without touching the model. Coding agents rely on a "harness" of prompts, tools, and configurations that shape how they work. Tuning this harness is usually manual, slow, and breaks easily. A new paper introduces Agentic Harness
