Black Forest Labs FLUX.2 [pro|flex|dev|klein]: near-Nano Banana quality but Open Weights
Black Forest Labs releases FLUX.2 in four variants — Pro, Flex, Dev (32B open weights), and Klein — adding multi-reference support for up to 4-megapixel output and a new variational autoencoder.
Black Forest Labs' FLUX.2 release features Multi-Reference Support for up to 4 Megapixel output and up to 10 images with consistency, including four form factors: Pro, Flex, Dev (32B Open Weight model), and Klein (TBA Open Weights). The new FLUX.2 - VAE introduces a variational autoencoder optimizing learnability, quality, and compression. Meanwhile, Anthropic's Claude Opus 4.5 demonstrates strong performance and efficiency, scoring 70 on Artificial Analysis, tying with GPT-5.1 high and trailing Gemini 3 Pro (73).
Opus 4.5 excels in agentic coding benchmarks and research evaluations, with notable token efficiency and reduced running costs. "Opus 4.5 leads Gemini 3 Pro on SWE-Bench Verified and tops the AICodeKing leaderboard," and it shows strong QA and systematic review capabilities. Anthropic also released a dense prompting guide for Opus 4.5.
