đ° AWS + AI = Amazonâs Profit Engine

AWS, Amazonâs cloud computing business, reported 28% sales growth, suggesting the online retail giantâs biggest AI bets are paying off.
Key details:
On Wednesday, Amazon announced earnings for Q1 FY2026, with net sales increasing 17% to $181.5 billion, operating income increasing 30% to $23.9 billion, and net income increasing 77% to $30.3 billion when compared to Q1 FY2025. For context, Amazon outperformed Wall Streetâs net sales expectations, beating the $177.2 billion projection by $4.3 billion.
Itâs important to note that Amazonâs reported net income is inflated because it includes a $16.8 billion pre-tax valuation gain from Amazonâs investment in Anthropic. In simple terms, because Anthropicâs FMF increased, Amazon recorded that increase as a net gain on the income statement.
Key takeaways:
AWS and OpenAI recently expanded an existing $38 billion multi-year compute capacity agreement by $100 billion over eight years. This expansion includes Amazon investing $50 billion in OpenAI in exchange for its consumption of 2 GW worth of Trainium capacity through AWS. Amazon also announced a strategic collaboration with Anthropic that includes investing up to $20 billion and supplying up to 5 GW of compute in exchange for Anthropic spending $100 billion over the next ten years on AWS.
Whatâs notable isnât just AWSâs impressive sales growth. Itâs how that sales growth is being engineered. By anchoring Amazon CEO Andy Jassyâs $200 billion AI spending spree to customer commitments with frontier AI firms like OpenAI and Anthropic, Amazon effectively locks in demand before supply is fully brought online.

MIT CSAIL recently developed âRLCR,â which trains language models to generate calibrated confidence scores alongside their answers. So, what shortcoming is this intended to address?
Key details:
Todayâs language models are statistical systems or estimation engines designed to predict the probability of a sequence of words. In simple terms, theyâre essentially sophisticated autocomplete machines trained on the entire internet.
For example, when given: âThe cat chased the {BLANK}!â language models ask themselves, given the words so far, whatâs the most likely next word? In this case, it might predict: â{MOUSE}!â
The fundamental issue is the âmismatch of objectives.â In other words, a language model is trained to process diverse inputs and generate plausible outputs that sound human.
That means if the most âprobableâ next word within a sentence is factually incorrect but grammatically correct, the language model will pick it because it lacks grounding: it canât double-check a fact against the real world. It can only check if the next word within a sentence fits the statistical patterns it learned from billions of training examples.
With RL, reasoning models earn the same reward for right answers whether they carefully reason or correctly guess. Over time, this teaches them to confidently answer every question theyâre asked, whether supported by strong evidence or pure guesswork.
Key takeaways:
The worldâs best frontier AI models, such as OpenAIâs âGPT-5.5,â arenât just passive next-word predictors in practice. Theyâre often wrapped in retrieval and reasoning. Even so, âGPT-5.5â can still hallucinate when it lacks reliable external verification because the core algorithmic architecture still functions as a sophisticated autocomplete machine that confidently guesses when it doesnât know.
The worldâs best frontier AI models donât reliably know when they might be wrong. âRLCRâ is engineered to fix miscalibrated confidence. In simple terms, it isnât trying to make them better at getting answers right. Itâs trying to make them better at learning when not to answer.
