Introducing Claude Sonnet 5 \ Anthropic anthropic.com
AI Weekly's analysis →
  • Anthropic released Claude Sonnet 5 on June 30, 2026, calling it 'the most agentic Sonnet model yet' and pitching it for autonomous browser and terminal use.
  • Through August 31, 2026 Sonnet 5 costs $2 per million input tokens and $10 per million output, then steps to standard rates of $3 and $15.
  • A new tokenizer means the same input can map to roughly 1.0 to 1.35 times more tokens than prior Anthropic models, partly offsetting the headline discount.

AI Weekly's analysis →
  • DiffusionGemma 26B-A4B generates text in parallel using diffusion refinement rather than token-by-token decoding.
  • The 4-bit quantized model requires only 18 GB RAM and reaches 2,000+ tokens per second on an RTX 6000.
  • Speed comes at a cost: AIME 2026 accuracy drops from 88.3% on standard Gemma 4 to 69.1% on DiffusionGemma.

I asked my wife to stop me from subscribing to GPT Pro. Her answer was pretty convincing: "Is it going to improve your work so much that you won’t need to upgrade to a higher plan, kind of like that Black Mirror episode?"

"I hate AI because it steals our noble work. Oh, is it just stupid code? That's fine then."

Just heard this one: "Art is about expressing thought; the artist is a thinker before anything else. The technique comes only at the materialization step. That's what people who think AI Art is Art don't understand." Sure, nice that you admit the prompter is an artist.

You might think this is a transphobic comment, but it is about AI.

AI backlash is all about narcisistic injury and ego protection.
