Alphabet began September with a new AI model, a cybersecurity offering and a favorable antitrust ruling, following a four-month losing streak for Google shares, the company’s longest since 2015. Gemini 3.8 Flash, launched Wednesday as the company’s third Flash model in six weeks, emphasizes coding, reasoning and agentic tasks (multi-step AI actions), while Gemini 3.8 Flash Cyber targets trusted government and enterprise defenders. Google says the latest Flash model improves on Gemini 3.7 Flash and costs 75 cents per million input tokens and $3.75 per million output tokens. Alphabet is also expanding Gemini Enterprise with pay-as-you-go pricing, discounts of up to 20% on tokens, monthly agent-spending caps and a zero-dollar base subscription. Berkshire Hathaway CEO Greg Abel said the company views Alphabet as an AI winner, while Google Cloud CEO Thomas Kurian said nearly three-quarters of Google Cloud customers use its AI products and spend about 50% more than their original commitments. Alphabet’s advertising business grew 14% in the latest quarter, and a federal judge rejected the Justice Department’s request to force Google to sell its AdX ad exchange, choosing behavioral remedies instead. The decision follows last year’s rejection of demands to divest Chrome. Analysts remain divided over Google’s enterprise AI position, with D.A. Davidson analyst Gil Luria saying the new model keeps Google in the race but likely leaves it a distant third behind Anthropic and OpenAI. The stock rose 0.6% Wednesday after falling more than 1% Tuesday, leaving it slightly lower for September so far.
