Maxim AI has released Bifrost, an open-source AI gateway designed to unify access to multiple large language model providers. Bifrost offers a single OpenAI-compatible API endpoint that routes requests to services like AWS Bedrock, Google Vertex AI, Google Gemini, and Anthropic's native API. This solution aims to simplify enterprise AI deployments by managing different authentication schemes, SDKs, and request protocols, while also providing built-in failover and governance capabilities.

Anthropic is retiring specific versions of its Claude 4 Opus and Sonnet models, claude-opus-4-20250514 and claude-sonnet-4-20250514, on June 15, 2026. This deprecation affects not only direct calls to these snapshot IDs but also the versioned aliases like `claude-opus-4-0` and `claude-sonnet-4-0` that resolve to them. Developers using these models should update their code to reference newer versions, such as `claude-opus-4-1`, and be aware that partner platforms like AWS Bedrock and Google Vertex AI may have different retirement schedules. Additionally, teams relying on mocked SDK tests or model-router fallback configurations need to implement integration tests against live APIs to ensure their systems do not silently fail after the June 15 deadline.

Amazon Bedrock now supports programmatic tool calling (PTC), a new method for large language models to interact with external tools. PTC allows models to generate code that invokes multiple tools simultaneously within a sandboxed environment, significantly reducing latency and token consumption compared to traditional sequential tool calls. This approach is particularly beneficial for complex data processing and multi-step operations, with AWS offering three implementation methods on Bedrock. AI

A new approach allows running open-source LLMs like Llama 3 directly within AWS Lambda containers, bypassing traditional API providers for specific tasks. This method leverages model quantization and increased Lambda container limits to enable self-hosting of LLMs on serverless CPUs. While not universally cheaper than managed APIs, it offers significant cost savings and enhanced privacy for high-volume, low-reasoning workloads. AI

Anthropic launched Anthropic Academy, offering 17 free courses with completion certificates, accessible via Skilljar. The academy is divided into two paths: one for developers focusing on Claude Code and API integration, and another for non-technical founders covering effective interaction with Claude. While most courses are recommended, some advanced or enterprise-focused modules are suggested for skipping by indie hackers. AI

Amazon Bedrock has introduced AgentCore, a new capability designed to overcome the limitations of context windows in large language models. This feature enables models to process and reason over documents of virtually any length by treating the input as an external environment. It utilizes a Recursive Language Model (RLM) approach, where a root LLM agent orchestrates analysis by generating code to interact with document chunks, delegating semantic tasks to sub-LLMs, and accumulating results in persistent working memory.

AWS has introduced Amazon Bedrock AgentCore, a managed service designed to simplify the creation and deployment of multi-tenant AI agentic applications. This platform addresses key SaaS architectural challenges such as tenant isolation, data security, and cost attribution. By utilizing session-isolated microVMs, AgentCore offers robust security and operational efficiency for various use cases, including business intelligence, recruitment assistance, and dashboard automation.

Anthropic has released version 0.29.2 of its TypeScript SDK for Amazon Bedrock. This update includes a changelog detailing the specific modifications from the previous version, bedrock-sdk-v0.29.1. The company emphasizes that user feedback is taken seriously in their development process. AI

Major book publishers have filed a class-action lawsuit against Meta, alleging massive copyright infringement in the company's AI training data. Separately, Italian Prime Minister Giorgia Meloni criticized the spread of AI-generated deepfake images, including a lingerie picture of herself. The increasing costs associated with AI development are expected to translate to higher prices for consumers, while companies like Hapag-Lloyd are leveraging platforms like Amazon Bedrock for customer feedback analysis and Amazon SageMaker for streamlining generative AI development.
