Taming Context Explosion in OpenAI Assistants/Responses with Go: Truncation, Summary Backfill, and Cost Caps

Mon, 02 Mar 2026 12:44:00 +0000

Long-running agent sessions usually fail the same way: context keeps growing, latency spikes, costs blow up, and answer quality gets worse.

That is rarely a model-quality issue. It is almost always missing context governance.

Go + OpenAI API Timeout Troubleshooting: DNS, TLS, Proxy, and Connection Pool

Mon, 02 Mar 2026 01:12:10 +0000

When OpenAI API calls start timing out in production, the real problem is usually not “OpenAI is down.”

The real problem is you don’t know which hop is failing: DNS, TLS handshake, proxy path, or your own connection pool.

OpenAI Agents SDK with Go: Tool Calling, Session Memory, and Error Recovery

Wed, 25 Feb 2026 01:18:00 +0000

Most teams can connect an LLM in a demo. The real pain starts in production: multi-step tasks, flaky tool calls, unclear retries, and rising cost.

This guide gives you a pragmatic Go-first blueprint for shipping an Agent workflow that can survive real incidents.

OpenAI Responses API Streaming in Go: Timeouts, Retries, and Observability

Mon, 23 Feb 2026 01:15:00 +0000

Production streaming fails in two predictable ways: users wait while the stream silently drops, and your logs say “timeout” without telling you where it actually broke.

This guide gives you a practical Go pattern for OpenAI Responses API streaming with strict timeout boundaries, safe retries, and useful telemetry.

Go Memory Leak Triage in Production: pprof + FlameGraph Step by Step

Sat, 14 Feb 2026 21:20:00 +0800

If your Go service RSS keeps climbing, drops after restart, then climbs again, you likely have a memory retention problem (or an actual leak pattern).

Do not start with random code edits. Run a clean evidence chain: metrics trend check → pprof snapshots → FlameGraph comparison → object growth path → regression validation.
