THESE TWO LINES OF CODE ARE SAVING COMPANIES UP TO 70% ON AI SPEND

THE BIGGEST FALSE DICHOTOMY IN AI: a costly frontier model for everything, or a cheap model everywhere. (Only to restart tuning with each new model release.) Finest finds the model your work needs: 👉 FINEST API [5] serves a lower-cost configuration only when it clears your task's quality bar. Otherwise, the model you named serves. 👉 FINEST CODE [6] brings the same evidence-gated approach to Claude Code, with Claude as the default and fallback. All you do is change two lines of code. You keep your prompts, model IDs, tools, and workflow.

03STRATEGIES & TACTICS

THE COMPANY DOES NOT LIVE IN THE LLM

Deterministic systems should be used to establish context. Large language models should be used to reason over that context. Models shouldn't be used to establish whether something has happened or what the current state of a system is. Systems should be used to assemble that information into context so that models can interpret, connect, reason, and synthesize.

CITATION SHARE IS NOT A METRIC YET

The discovery layer and the infrastructure layer have never been equally measurable. The industry puts all of its attention and spend into the layer where the numbers are contested, produced by interested parties, and unstable across instruments. The layer that determines whether agents can transact with them at all returns a clean pass or fail on every check. Both citation and infrastructure matter, but infrastructure is what gets you transacted with.

"I'M CHURNING" | 10 BIGGEST THREATS TO SAAS

This is the person on the other side of your renewal itemizing how he decides to cancel. A working CFO lists what he is cutting and why, including a workflow tool that quoted him double what he pays for Claude and a $ 50K-a-year point solution whose function a larger vendor now bundles for free. His own playbook is opening renewal conversations four or more months early, and he reckons 30 to 60 minutes of demoing alternatives buys enough negotiating power. Backdrop is the Bessemer cloud index up 55% in six months, its highest since early 2022.

THE "PLAYER-COACH" ROLE IS BECOMING INCREASINGLY HARDER

Teams using coding agents open 6x more pull requests than traditional teams and 3x more than they did in 2024, according to Linear's report on AI usage in software teams. Review load is climbing faster than anyone's model of the job, which is the likeliest way your first engineering manager hire burns out. Managers already see only about 40% of what a report does in a day. The squeeze lands hardest on engineering managers and tech leads: the people expected to write code and manage at once.

KEEPING CREDENTIALS OUT OF AN AI AGENT'S CONTEXT WITH RELAY

WorkOS Relay proxies third-party agent API calls and injects the credentials at the boundary so prompt injection attacks are unable to steal tokens. It lets apps call third-party APIs on behalf of users without directly handling secrets. Requests are proxied through WorkOS, where credentials are swapped in based on the user and organization context. Relay is still in early access, and access requires contacting support.

BEHIND THE BUILD: GENERATIVE PLUGINS AND SHADERS AT FIGMA

Figma has introduced generative plugins and shaders to the canvas to give users a way to design the tools they need, when they need them. Users can publish plugins and shaders to the Figma community or privately within organizations on Organization or Enterprise plans. The agent can build motion and interactivity into any effect, and users can view and download the code behind any shader or plugin. The Figma MCP server can be used to view, change, and export generative plugins and shaders.

INTRODUCING ADAPTIVE INTELLIGENCE: UNDERMINING THE ECONOMICS OF EVERY BOT ATTACK

Adaptive Intelligence is a new bot detection engine from Cloudflare that makes getting through so slow and costly that attacks stop being worth running. Not every attack is obvious to spot, and the economics of deterministic detection are always in the attacker's favor. Adaptive Intelligence makes sure that nothing attackers learn stays true, so each new attempt costs more than the last. It recognizes bots without visibly reacting to them and treats detection as a statistical judgment, weighing many signals at once so there's no single piece of logic for an attacker to isolate and beat.

05MISCELLANEOUS

WHY ADDING MORE AI AGENTS MAKES YOUR TEAM SLOWER

Agent scaling is about how cleanly a system allows agents to work in isolation without stepping on each other all the time. This requires expertise in the problem domain, a keen eye for good architectural decisions, and good measurement. Coding is the easy part of writing software - it's everything else that takes most of the time. There's only so much you can streamline before you start losing a significant amount of quality.

“ENSHITTIFICATION” ISN'T REAL

"Enshittification" isn't real. Social media platforms change to meet evolving user needs, not to worsen user experiences. Despite complaints, user satisfaction and engagement with platforms like Instagram continue to rise. Critics mistake platform evolution and user dislocation for deterioration, but the data shows that people use these platforms more, not less.
