OpenAI is permanently shutting down the Assistants API. Every app using assistants, threads, or runs — including Azure OpenAI — will stop working. We handle the entire migration to the Responses API.
Assistants API, threads, runs, file search — all dead. No exceptions. No extensions.
Responses API has different patterns, tool handling, and thread management. One wrong assumption = broken features.
If your assistant powers customer-facing features, the deadline isn't Aug 26 — it's whenever testing and QA finishes before that.
Migration slots fill up. Engineers book out. The closer to the deadline, the more expensive and rushed it gets.
Pick the level that matches your needs. Every option includes a clear before/after map.
30 min — we map your current API usage and goals
Full usage map, risk register, migration plan delivered
Endpoints, tools, threads all migrated with smoke tests
Rollout checklist, monitoring, 1 week post-launch support
If we can't map a clean migration path, the audit is free. We only take on projects we're confident we can deliver.
Yes. Azure OpenAI's Assistants API retires the same day — August 26, 2026. The migration path is the same.
The Responses API has native file search support. We map your current vector store setup to the new equivalents with parity testing.
Audit: 48 hours. Standard migration sprint: 3–10 working days depending on complexity. We give you a fixed timeline after the audit.
Your app stops working on August 26, 2026. API calls to assistants, threads, and runs will return errors. There is no grace period.
Book a 48-hour audit. Know exactly what needs to change — before the panic starts.
Book Your OpenAI Migration Audit →Or email budzamar@gmail.com with "Migration Audit" in the subject
Setup time: 30 minutes to audit your codebase and kick off the migration.
hermes run --prompt "Scan the codebase in ~/projects for OpenAI Assistants API v1 usage. Find: assistants.create, threads, runs, openai.beta.assistants references. List every file, the deprecated call, and the line number. Categorize as: (a) prompts only, (b) threads + conversations, (c) streaming, (d) file handling. Deliver to ~/openai-migration-audit.md"
hermes run --prompt "Using ~/openai-migration-audit.md, produce a detailed migration map: for each deprecated v1 call, show the equivalent Responses API v2 replacement. Include: (1) old vs new code, (2) breaking changes for each, (3) test strategy, (4) estimated effort per endpoint. Save to ~/openai-migration-plan.md"
