OpenAI Deprecation — Hard Cutoff Incoming

109|

OpenAI is killing the Assistants API v1. Your AI product stops working if you don't migrate.

110|

Prompts are becoming built-in tools. Threads are becoming Conversations. The async model is fundamentally changing. This is not a version bump — it is a full architectural rebuild. If you built your product on Assistants API v1, the deadline is real and your product will break.

The Problem

123|

This is NOT a find-and-replace.

124|

OpenAI is not deprecating a few endpoints. They are restructuring the entire interaction model. Your code, your state management, your streaming logic — all of it must change.

125| 126|

127|

128|

Prompts (dashboard-only, UI-configured)

129|

→ Built-in Tools (code-level, API-driven)

130|

Prompts you configured in the OpenAI dashboard must now be defined as built-in tools in your API calls. Dashboard-only prompts will not work in v2. Every prompt must move into your codebase.

131|

132|

133|

Threads (persistent, API-managed state)

134|

→ Conversations (new lifecycle, new semantics)

135|

Threads are replaced by Conversations with a fundamentally different state model. Your existing thread management, context windows, and message history logic will not survive the transition.

136|

137|

138|

Async model (runs, polling, status checks)

139|

→ New streaming & sync/async behaviour

140|

The entire async execution model — runs, retries, polling loops, status-check logic — changes. Streaming behaviour is different. If your product relies on real-time responses, this is a rewrite.

141|

142|

143|

File handling & tool outputs

144|

→ New attachment & output structures

145|

File uploads, code interpreter outputs, and function call responses all change format. Every integration point — retrieval, code interpreter, function calling — needs updating.

146|

147|

148| 149|

150|

⚠️ This is an architectural migration, not an upgrade.

151|

If you treat this as a find-replace on your API calls, your product will break in production. The state model is different. The streaming model is different. The tool model is different. We migrate your entire integration — correctly — in one engagement.

How It Works

159|

Three steps. One migration. Zero downtime.

160|

We assess your entire Assistants API integration, migrate every endpoint and state model, and validate against production traffic — so your product keeps working.

161|

162|

163|

164|

Assess

165|

We audit your entire v1 integration — every Prompt, Thread, Run, and streaming call. You get a migration map showing exactly what changes and where.

166|

167|

168|

169|

Migrate

170|

We rewrite the integration layer: Prompts to built-in tools, Threads to Conversations, async runs to the new model. Your business logic stays intact — only the API layer changes.

171|

172|

173|

174|

Validate

175|

We run the migrated integration against your full test suite and live traffic patterns. Streaming, tool calls, file handling — every path is verified before we hand it back.

Pricing

184|

One migration. One price. Done.

185|

This is not a subscription. It is a one-time migration engagement. We move your product from v1 to v2 — completely.

⚠️ This is NOT for you if:
you want get-rich-quick schemes, expect overnight results, are looking for "hype" AI tools, or can't be bothered to follow a 5-minute setup.

✅ This IS for you if:
you want boring automation that quietly makes money, you value reliability over flash, and you believe one person with the right systems can build a real business.
