Why agent latency matters more than raw model speed
Agent latency vs model speed decides UX and cost. We break down why step overhead dominates and how to measure end-to-end agent performance.
Streaming vs batch responses: latency tradeoffs for agents
Compare streaming vs batch latency for AI agents: capabilities, cost, throughput, ergonomics, and limits to decide which delivery mode fits your system.
Small models vs large models: when an 8B model beats GPT-5
A practical head-to-head comparison of 8B small models versus large frontier models like GPT-5 for AI agents, covering cost, latency, and capability trade-offs.
Measuring cost per successful task, not cost per call
Stop optimizing LLM spend by cost per call. Learn why cost per successful agent task is the metric that matters for agentic systems, with code.
How to benchmark agent latency across providers
Learn how to benchmark agent latency providers with instrumented loops, repeated trials, and statistical analysis to optimize LLM agent performance.
How fallback routing prevents costly agent retries
Practical guide to fallback routing for LLM agents: stop blind retries, cut cost and latency with gateway-level provider failover and routing directives.
Cutting p99 latency in multi-step agent pipelines
Practical guide to cutting p99 latency in multi-step agent pipelines: parallelism, aggressive timeouts, caching, and speculative execution with code.
Caching tool results to speed up agent loops
A practical guide to caching tool results agents in autonomous loops: reduce LLM latency and spend with deterministic memoization and TTLs.
What drives AI agent costs, and where the money goes
An AI agent cost breakdown maps spend across LLM tokens, tool calls, and orchestration loops so engineers can predict and cut costs in autonomous workflows.
Model routing for cost: when to downgrade to a cheaper model
Practical guide to model routing cost optimization: how to downgrade to cheaper LLMs safely in AI agents, with code and tradeoffs for engineers.
How to cut agent API costs by 60% with prompt caching
Practical steps to implement LLM prompt caching in agent loops, cutting repeated token costs by up to 60% with provider cache controls and gateways.
GPT-5 vs Claude Opus 4.5 vs Gemini 3: cost per agent task
Head-to-head GPT-5 vs Claude Opus 4.5 vs Gemini 3 for agents: cost per task, latency, ecosystem, limits, and which model to choose by use case.
Batching LLM calls to cut agent inference costs
Learn how to batch LLM calls to cut agent inference costs with OpenAI-compatible batch APIs, step by step, including runnable Python code and tradeoffs.
8 ways to reduce token spend in production agents
Practical engineering tactics to reduce token spend agents incur in production, from prompt caching to model routing and output constraints.
