AI Tools + ETF Weekly: Ultrafast inference, Git agents, and a split flow tape

AI tools

• Ultrafast inference: OpenAI's August 13 preview describes an API service tier for GPT-5.6 Sol that can run up to 14 times faster than Standard, with up to 750 output tokens per second. It is powered by Cerebras and remains a preview, so the useful comparison is not speed alone: availability, workload fit, and economics still matter. 1
• Pull-request context: Visual Studio Insiders' August 11 notes add a Git agent that can inspect a pull request, answer questions about its discussion and changed files, and return links into the relevant comments and files. GitHub and Azure DevOps MCP servers can provide more context. The same release also previews Bring Your Own Key for Microsoft Foundry and other supported providers. 2
• Encrypted inference: Google's August 14 security post introduces HEIR, an open-source compiler and toolchain for homomorphic encryption. Google describes demonstrations in recommendation, fraud detection, threat detection, and hotword recognition. The open questions for adoption are latency, supported operations, hardware cost, and model-conversion work—not whether encrypted inference sounds promising. 3

ETF market

• Flows: ETF Action's August 14 report recorded $5.75 billion of net ETF inflows for the day. Fixed income led with $2.97 billion, equities followed with $2.77 billion, and commodities saw $262.4 million of outflows. Ultrashort government bonds attracted about $968.9 million, while U.S. large-cap growth funds lost about $1.56 billion. The report also warns that daily outliers can reflect specialized rebalancing, particularly as actively managed ETFs expand. 4
• A daily cross-check: ETF.com’s August 14 report for August 13 named the iShares 0–1 Year Treasury Bond ETF, ticker SGOV, the top fund in its daily flow ranking. That reinforces the short-duration demand signal, but a flow ranking is not a return forecast. 5
• Price performance: CNBC reported a third consecutive weekly gain for the S&P 500, while the cross-section was less uniform: the SPDR S&P Retail ETF fell about 2% for the week and the iShares MSCI Brazil ETF fell about 4.8%. ETF flows and price performance answer different questions, so they should be read side by side rather than treated as cause and effect. 6
• New products: A Nasdaq-published RBC iShares release dated August 10 announced two ETFs beginning to trade on the Toronto Stock Exchange. XINT is a diversified international-equity fund outside Canada and the United States with a stated management fee of 0.23%; IBQT combines global equity ETFs with a modest bitcoin allocation and a stated fee of 0.22%. XINT is a geographic equity sleeve, while IBQT adds digital-asset exposure inside a portfolio wrapper; neither launch date establishes a trading history. 7
