Anthropic launches cheaper AI model Sonnet 5.5
Anthropic expanded its Claude 5.5 series with Sonnet 5.5 and Haiku 5.5, featuring cost reductions and performance gains. Sonnet 5.5 is 30% faster and up to 30% cheaper, priced at $2/$10 per million tokens. Haiku 5.5, designed for high-volume agentic tasks, is priced at $0.10/$0.50 per million tokens (under 100K tokens), scores 43 on the Artificial Analysis Intelligence Index (surpassing GPT-6 Luna and Gemini 3.8 Flash), supports 1M-token context, and introduces effort settings. A new tokenizer counts 30% more tokens, but costs are 75% lower. Both models are available on major platforms with integrations. Other AI news includes OpenAI's release of 719 math papers from an unreleased model, Mistral's Le Chonk and Reflection AI's Beam open-weight models, an OpenAI researcher's resignation, Google's public SynthID, OpenAI's EU watermarking, and industry moves like TikTok's shopping assistant and ElevenLabs' valuation doubling.
