[Blog] Infer-forge: Loop and Graph Engineering Around SGLang

[TianyuZhang1214]

Summary

This PR adds “Infer-forge: Loop and Graph Engineering Around SGLang,” a technical blog describing our agent-driven engineering practice for managing inference-system complexity around SGLang. Infer-forge builds from Harness Engineering to long-running Task Loops, then composes independently verifiable Tasks into project-scale Task Graphs.

What the Article Covers

• Inference as a deployment space: An optimization is meaningful only within a complete deployment point spanning the model, serving scenario, SLO, topology, runtime, and accelerator platform.
• MonoRepo and Harness: A reproducible cross-repository workspace connects kernels, communication libraries, SGLang, deployment, Evaluation, diagnosis, memory, compute resources, and safety boundaries.
• Task Loop: A persistent Task can advance across multiple Agent executions while preserving its contract, evidence, Verification boundaries, and Handoffs.
• Task Graph: Multiple Tasks can be coordinated into large engineering projects and capability-evolution workflows without losing provenance, constraints, or paths that did not ship.
• Lessons learned: The article discusses Task granularity, evidence-driven graph evolution, verifiable Deliverables, and why Context, Harness, Loop, and Graph accumulate rather than replace one another.

Evidence from Practice

• From April to July, the peak number of inference-engineering Tasks under concurrent management rose from 2 to 9. Observed peak engineering concurrency therefore rose 4.5×.
• A large DeepSeek-V4-Pro serving optimization project was organized as 38 independently verifiable Task nodes across seven Task Types.
• The project delivered four serving profiles while preserving seven paths that did not enter the final Release, keeping both successful and unsuccessful engineering decisions reproducible and auditable.
• These figures are longitudinal operating observations from one engineer, not a controlled productivity benchmark.

Assets and Validation

• Adds a dedicated blog cover and 16 technical figures.
• Verifies that all local image references resolve correctly.
• Passes git diff --check.
• Passes the complete npm run build.
