How to Sell Usage Credits in an AI App Without Billing Surprises

·2 views

A developer in Hyderabad explains how AI app builders can charge customers by usage, since flat monthly pricing breaks down when a few users consume far more than others. Credits are presented as the common solution, with the customer paying in advance for a balance that is drawn down with each use. The guide compares three models: credit packs, a monthly allowance within a subscription, and billing for usage after the fact, noting that prepaid options are generally easier to explain and less likely to surprise customers. It recommends choosing a unit customers understand, such as one credit per image, and pricing based on the real cost of each use plus a margin covering payment fees and retries. The author also advises testing the full flow in test mode before launch, and notes that payment provider features referenced in the article may change.

AI Can Generate Code, but Engineers Are Still Needed to Make Software Work

Tech leaders Marc Benioff of Salesforce and Mark Zuckerberg of Meta have predicted that AI will transform software engineering, with Benioff citing productivity gains for possibly limiting 2025 hiring. The article argues that generating code is only one part of building dependable software, since engineers must grasp user needs, integrate changes into complex systems, and verify outcomes. A 2025 METR study of 16 experienced developers found they took about 19% longer on tasks with AI tools, even though they believed the tools had sped them up. Google's 2024 DORA research linked higher AI adoption to lower delivery stability across the organizations it studied, though it did not establish causation. The piece concludes that AI will reshape engineering work but will not remove the need for human judgment, review, and responsibility.

Why a clean static analysis scan can still miss real vulnerabilities

A security series author ran a free static analyzer on their own service's code and got zero findings with its default rule set. A second run using a JavaScript-specific rule set flagged the post-login redirect logic, and the underlying flaw went unnoticed by every Semgrep rule set they tried. An AI code reviewer caught the issue when the fix was tested, and it has since been patched. The author's takeaway is that zero findings does not guarantee safety, so developers should layer different checking methods, verify every hit, and rerun scans regularly. The piece also notes that static analysis can reveal secrets such as API keys left in git history, including a deactivated AWS key found with Gitleaks.

How Remote Teams Can Choose the Right Online Whiteboard Tool

Online whiteboards have replaced physical walls for remote and hybrid teams, supporting brainstorming, retrospectives, diagrams and design work. The article argues that tools look alike in demos, so differences only emerge after weeks of real use with large boards and many participants. It recommends first listing the main situations where a team will use a whiteboard, then ranking them to decide which trade-offs are acceptable. Teams should test the canvas with realistic content, including performance on large boards, text handling, connectors, frames and recovery options. Collaboration features such as cursors, facilitation tools, guest access and asynchronous commenting also deserve trial sessions before a decision is made.

Researcher Claims Flaw in Vaani Voice AI Let Him Hijack Agents Across Tenants

A security researcher describes finding a flaw in Vaani, a voice AI agent platform that won Product Hunt's top daily spot, at a company hackathon. He says a single HTTP request from a free account could take over AI agents belonging to other customers, redirecting their outbound calls to read attacker-supplied prompts. The issue reportedly stemmed from predictable agent identifiers that were not properly protected by access controls. The researcher says he demonstrated the hijack without accessing private data and that the vendor has since patched the problem. The account highlights risks in multi-tenant voice AI systems that place outbound phone lines under automated agent control.
