Agent Stack: APIs, Memory, GPU Slicing, Coding Agents, and Inference Racks

Components of a Coding Agent breaks coding agents into six essential components, showing how context, tools, memory, and harnesses make LLMs practical for software work. This gives outcome engineers a checklist for building reliable agent delivery lanes and harnesses that reduce brittleness in production (Principle 06/11).

research-llm-apis — 2026-04-04 release catalogs raw JSON and curl patterns across LLM vendors and proposes redesigned abstractions for server-side tool execution. Outcome engineers can use it as a vendor-agnostic reference to standardize adapters, reduce brittle glue code, and design deterministic tool interfaces (Principle 03).

LLM Wiki — example of an ‘idea file’ shows a concrete pattern for agents to build and maintain a persistent, interlinked wiki that captures evolving knowledge instead of re-deriving it each query. If you need agents that carry context and provenance across runs, this is a practical memory/knowledge-graph pattern to adopt (Principle 11/06).

sllm — Split a GPU node with other developers, unlimited tokens launches a GPU-slicing service that lets teams share nodes for low-cost, multi-tenant model access with unlimited tokens. This lowers the cost of iteration for agent development and supports fast feedback loops across teams, changing how you budget and run agent experiments (Principle 07/04).

Korean startup launches RebelRack and RebelPOD inference racks, claims 6x lower power and up to 75% cheaper than Nvidia unveils new inference hardware claiming major gains in energy efficiency and lower acquisition costs for on-prem inference. If those figures validate, outcome engineers gain a new economic lever for deploying high-throughput agents on-prem — rethink cost models, placement, and artifact shipping (Principle 08/12).
