   Nikkei Crosstech NEXT Tokyo 2026 opens, AI-driven development in focus

   The Nikkei Crosstech NEXT Tokyo 2026 conference has opened, with a focus on AI-driven development. The event is described as a chance to experience the power of AI-driven development firsthand.

   The conference is framed around hands-on experience, so its impact hinges on what attendees take away from the sessions.

   The Boring Co. Tops $3B Week With $23B Valuation

   The Boring Co. raised a $3 billion Series D led by the United Arab Emirates, valuing the tunnelling company at $23 billion. Three others also raised $1 billion or more: Cognition, Motive and Stoke Space. Four companies hit $1 billion-plus in a single U.S. week. The Boring Co.'s total funding rose to nearly $3.9 billion, and Cognition jumped to a $48 billion valuation on a $2 billion round.

   Whether the surge trails into next week hinges on SpaceX-style space and defense demand. Watch Suniva's planned South Carolina facility, which would more than quadruple its manufacturing capacity.

   Reddit user seeks tools to turn React/Next.js code into fine-tuning data

   A Reddit user asked for tools or workflows that turn an existing codebase into a fine-tuning dataset, for example converting a React/Next.js project into instruction/prompt -> code pairs. The request shows a developer wants to build a dataset and benchmark to test a different model architecture aimed at better quality and speed with less VRAM, rather than relying on generic descriptions.

   The thread asks how to keep context between components and files, combine screenshots with code, and generate useful instructions. No specific tool, repo, paper, or workflow was named in the post.

   AWS shows MCP Apps on Amazon Bedrock AgentCore

   AWS published a step-by-step demo of Unicorn Rentals, an MCP App that lists, books, and returns unicorns, running on Amazon Bedrock AgentCore runtime and exposed through AgentCore Gateway. The same server renders the same interactive cards in ChatGPT and Claude. MCP Apps is host-agnostic, so organizations reach customers on ChatGPT, Claude, or other supported hosts without rebuilding for each. The thin protocol adapter delegates business logic to AWS Lambda and DynamoDB, which could be existing services.

   Since AgentCore runtime uses consumption-based pricing, production success hinges on right-sizing container memory and reviewing Lambda concurrency. AWS recommends AWS WAF, CloudWatch alarms, and Amazon Bedrock Guardrails at trust boundaries.

   OpenAI's Habitat Rewritten in Rust, 6x Faster

   In Q2 2026, OpenAI announced it rewrote its Habitat storage infrastructure from Python to Rust. The work was done by two engineers along with Codex and GPT-5.5. Habitat now handles over 70 million requests per second across nearly 40 regions for more than 1 billion weekly users. It has evolved from a single-database Python library two years ago.

   OpenAI says it will fully retire Python within weeks. The test will be whether the Rust version can maintain the same reliability.

   OpenAI opens Agents API beta, same infra as Codex

   OpenAI released the Agents API as a public beta. It runs on the same infrastructure as Codex and ChatGPT, with automatic context management, parallel tool use, and task delegation to sub-agents. Developers can now choose OpenAI-hosted sandboxes or partners like Cloudflare, Vercel, and Oracle, with no extra fees beyond token usage. This builds on the open-source Codex harness and supports MCP, custom functions, and web search.

   The test is whether developers adopt the partner sandboxes for production workloads, since billing is based solely on token usage. Watch how the public beta develops.
