GitHub Spark is shutting down August 31 — export code now and replace broken `llm()` calls

GitHub Spark stops being available to existing users on August 31, 2026. Deployed apps are meant to keep running, but owners should export code to a repository now; Spark apps using `llm()` need a separate inference provider because the underlying GitHub Models service retired July 30.

OpenAI’s Jalapeño chip posts its first public inference results ahead of 2026 deployment

Jalapeño is now working first-party silicon rather than a roadmap item. OpenAI reports materially better latency and throughput per kilowatt than compared Blackwell systems across GPT-OSS, DeepSeek and Kimi workloads, while SemiAnalysis says it inspected the chip and benchmarked it with its open InferenceX suite.

Supabase makes MCP access centrally governed through enterprise SSO

Supabase has implemented MCP Enterprise-Managed Authorization using identity-provider assertions, short-lived tokens and existing Supabase role boundaries. It gives organizations a central on/off switch for approved AI clients while keeping access scoped to the individual employee rather than sharing a powerful organization token.

OpenAI’s Assistants API has shut down

The Assistants API shutdown date has passed. OpenAI’s deprecation documentation lists August 26, 2026 as the removal date and directs developers to Responses and Conversations for replacement workloads.

OpenAI’s Codex client exposes a GenUI layer for refreshable interfaces inside conversations

RuntimeWire found a generic `genui` message path, a server-directed widget refresh endpoint and 467 versioned Learning Block manifests inside OpenAI’s Codex desktop client. The material development is not another visualization feature: it is evidence of a reusable interface layer beneath conversational answers, with important limits around what is actually public or enabled.

ChatGPT Ads expands self-service globally as targeting, measurement and campaign tooling deepen

ChatGPT Ads is moving from beta inventory toward a global performance-ad stack. OpenAI has expanded self-service buying and says optimized bidding is now the majority of campaigns, while new audience, measurement and workflow controls increase both scale and attribution complexity.

Cloudflare links AI code scanning to live edge exposure before proposing a fix

The interesting part is not another AI scanner. Cloudflare is connecting source-code evidence to what is actually deployed and being attacked at the edge, validating findings outside the model, then preparing both a code patch and, where appropriate, a narrowly scoped WAF mitigation for customer review.

Google Cloud is making every Application Integration run execute under an explicit identity

The migration turns integration identity from an implicit platform detail into an operational dependency. Teams may need new run-as accounts and `Service Account User` grants not only for runtimes but also for editors, publishers, approvers and deployment automation.
