OpenCode is an open-source AI coding assistant that works with your project’s files and tools. Here’s what that means, what changed in 2.x, and how to try a small repair without handing it your whole environment.
Follow the changes in learning methods, data and compute that led to today’s models, and see why newer does not always mean better for a task.
Unix, GNU, the Linux kernel and distributions explain the cooperating layers you operate today, including what a container actually shares.
Google’s new reasoning model promises to stay with difficult work. Here is what that means for coding, research and investigations, and how to check the result.
UserRepGen turns a conversation into task and behavior descriptions. Follow the intermediate artifact through a synthetic support-assistant evaluation.
PulsarLM removes low-attention pages rather than summarizing them. A synthetic archive-retention case explains what a local agent’s recall trial must inspect.
Worth understanding
Explainer
The global auto mode is only part of the permission decision. Follow per-tool overrides, directory scope and restored settings through a copied-runbook exercise.
Explainer
Scion reduces repeated repository work for online agents. Its cache hierarchy explains why warm checkout speed and fleet recovery need different tests.
Explainer
Helion places CPU agent loops, token routing, GPU inference and supporting services in separate capacity zones that still share one task outcome.
Reliability in practice
Incidents, on-call work, and the decisions behind reliable systems.
Separate detection from response and find delays that an improving average can conceal.
Guide
A backup cleanup can pass its tests while an older data format remains unverified. A risk registry preserves that distinction for the next engineering decision.
Guide
Disturbed nights, specialist help and cleanup consume capacity beyond the primary shift. A workload worksheet connects that demand to staffing and delivery plans.
Put it to work
Put incident timestamps in order and examine the intervals between failure, detection, investigation, and recovery.
Build a timelineTurn a known failure into a procedure with scope, actions, escalation, and recovery checks.
Build a runbookTrack corrective actions alongside verification criteria and the risk that remains.
