Anthropic released Claude Opus 4.8 on May 28, 2026, replacing Opus 4.7 at unchanged pricing. The company claims the model's misalignment rates match those of Claude Mythos Preview, the experimental model deemed too dangerous for public release in April 2026. Opus 4.8 delivers faster thinking modes at one-third the cost of version 4.7.

Google has released Gemini 3.5 Flash, a multimodal model with a 1 million token context window priced at $1.50 per million input tokens and $9 per million output tokens. The model supports text, image, video, audio, and PDF inputs with configurable thinking effort levels from minimal to high.
