Middleware Is the Kill Zone — Own a Vertical or Own the Control Plane
When the model itself performs distributed systems engineering — writing programs to coordinate tools, holding state across multi-hour sessions, choosing between scripting and direct interface manipulation — the customer's question is brutal: why pay for your orchestration when the runtime orchestrates natively? At monthly release cadence, 'the labs won't ship our feature' is no strategy.
Follow where a billion-dollar week did not go. Norm Ai ($1.2B, agentic law) and Lovable ($13.2B, code generation) got funded for vertical depth; SambaNova, Positron, and Prime Intellect for infrastructure. Horizontal tooling — wrappers, thin orchestration, general-purpose middleware — is squeezed from both sides, and investors are pricing that before operators are.
Two quieter moves show layer ownership. NVIDIA open-sourced 110+ agent skills portable across Claude Code, Codex, Cursor, and Kiro — quietly teaching every agent to depend on CUDA-X libraries. Open spec, closed gravity: the Android playbook for AI infrastructure. And the routing proxy is emerging as the API gateway of the AI era — open-source proxies like Plano claim 2x cost reduction with zero code changes. Prompt caching is model-specific, so a cache-hot expensive model beats a cache-cold cheap one: per-call routing is broken; session-level pinning is the pattern. Whoever owns that layer owns cost observability and vendor optionality.
Next 90 days:
- Map every product against what GPT-5.6, ChatGPT Work, and Muse Spark do natively.
- Where overlap exists, differentiate on proprietary data and vertical expertise — or reposition as infrastructure these runtimes consume.
- Own the control plane: adopt routing as configurable infrastructure now, not single-provider volume commitments that trade away optionality.
In an agentic-runtime market, the only defensible positions are below the model (infrastructure) or above it (vertical data) — everything in between is a feature awaiting absorption.
What to do
Map every product line against GPT-5.6, ChatGPT Work, and Muse Spark 1.1 within 30 days; flag features the runtimes now ship natively and assign a differentiate-or-reposition call to a named owner
Stand up an open-source routing proxy (Plano or equivalent) as the control plane between all agent services and model providers this quarter, with session-level model pinning as default policy
