Newton’sWhat can be observed or verified
Provider documentation, published pricing, product behavior, response records, and measured system state.
NEWTON’S RESEARCH · AI INFERENCE ECONOMICS & INFRASTRUCTURE RESEARCH
How model choice, pricing, caching, reliability, and access method change the real cost of AI work.
Research for builders comparing models, APIs, subscriptions, and gateways using the conditions that actually shape a workload.
How to read this research.
Each article distinguishes documented facts, reasoned conclusions, and questions that still need testing.
What follows from the evidence
Economic and product conclusions that become stronger or weaker as the observed facts change.
What remains to be tested
Long-range claims about market structure are labeled as hypotheses until product and market evidence earns more certainty.
Foundational research
Start with the governing economics before evaluating any particular provider or product.
INFERENCE ECONOMICS
Read research →The Same AI Workload Doesn’t Have One Price
Why model, provider, cache behavior, context, processing tier, latency, and commitment all change the economics of AI inference — and what that means for builders.
Questions before changing your workflow
Use these guides to compare the options that are available for your next workload.
TOOL COMPATIBILITY
Examine the argument →Codex and Claude Code Routing: What Changed by Aug 2026
A practical routing truth map for builders: where Codex and Claude Code keep native sessions vs where Newton’s route can be inserted safely.
DECISION GUIDE
Examine the argument →Why Not Just Buy Extra AI Credits When You Hit the Limit?
Sometimes you should. Compare the next available ways to finish the work: provider credits, a direct API, waiting, or a multi-model gateway.
DECISION GUIDE
Examine the argument →Subscription vs API vs Gateway: Which One Is Actually Cheaper?
There is no universal winner. Compare the marginal workload, not three products that meter value in different ways.
QUALIFICATION
Examine the argument →When You Should Not Use Newton’s
A useful infrastructure product should be able to tell you when a subscription or direct provider is the more rational choice.
Turn the argument into a decision.
Use a non-sensitive workload to compare the available options before moving more work.
