Check out the latest on Anthropic’s Claude Haiku 5.5 and Sonnet 5.5, along with Gemini 4 Argon and Mistral Large 4.

The AI race hasn’t slowed down. In the last week, Google, Anthropic and Mistral AI all released new AI models ranging from widely accessible to super exclusive. Each focuses on different improvements, but the stakes go beyond benchmark bragging rights. We break down the latest releases, what’s new,and whether each one deserves your attention.

Some of the latest releases are incremental updates in model speed and price, where others are more substantial upgrades that push close to the frontier. 

Below, we’ll break down some of the newest models that have been released and if and how you can get your hands on them yourself. 

A major theme in new AI models lately is speed and cost efficiency, and that’s what Anthropic’s new Haiku 5.5 model brings to the table. It’s the first major update in a year for the company’s cheapest and fastest Claude. Anthropic says it’s designed for high-volume, cost-sensitive tasks and can reliably handle quick, repetitive workloads. 

Compared with the previous Haiku model, Anthropic says its latest model costs about 75% less to run — an impressive price drop. It’s also seen substantial improvements across a series of benchmarks, including computer-use tasks, knowledge work, agentic coding and visual reasoning.

5 is Anthropic’s first Haiku-level model to ship with an adjustable effort setting, allowing users to optimize the model for cost or intelligence. The latest model has seen significant improvements in alignment and cybersecurity, with stronger safeguards.
