# Migrate Off GitHub Models in 15 Minutes: The Exact Endpoint Swap

> GitHub Models dies July 30. Because it spoke the OpenAI format, moving off it is a base-URL-and-key edit — not a rewrite. Here's the exact before/after for each destination, plus the one-env-var wrapper that means you never do this again.

## Key takeaways

- GitHub Models is fully retired on July 30, 2026, with brownouts on July 16 and 23. If your code calls https://models.github.ai/inference with a GitHub PAT or GITHUB_TOKEN, it breaks on those dates. The migration is small because GitHub Models implemented the OpenAI Chat Completions API — every replacement below is a base_url + api_key change, not a rewrite.
- The current call: an OpenAI() client with base_url='https://models.github.ai/inference', api_key=GITHUB_TOKEN (a PAT with models:read), and a model like 'openai/gpt-4o-mini'. You keep client.chat.completions.create() exactly as-is; you only change where it points and how it authenticates.
- The swaps, each one edit: OpenRouter → base_url 'https://openrouter.ai/api/v1', an OpenRouter key, model 'openai/gpt-4o-mini' (same namespaced IDs). Direct OpenAI → drop base_url entirely, an OpenAI key, model 'gpt-4o-mini'. Anthropic → base_url 'https://api.anthropic.com/v1/', an Anthropic key, a claude model ID via its OpenAI-compatible endpoint. Moonshot Kimi → base_url 'https://api.moonshot.ai/v1', a Moonshot key, model 'kimi-k2.7-code'. Local Ollama → base_url 'http://localhost:11434/v1', api_key 'ollama' (ignored), a pulled model like 'llama3.3'.
- The durable fix is to never hard-code any of these: read LLM_BASE_URL, LLM_API_KEY, and LLM_MODEL from the environment, build one shared client, and route every call through it. Switching providers becomes editing three env vars — no code change, no redeploy of logic.
- The CI note: GitHub Actions minted GITHUB_TOKEN automatically, so a lot of GitHub Models usage is hiding in workflows. Grep your repo for 'models.github.ai' and 'models:read', add the new provider's key as an Actions secret, and set the three LLM_* env vars in the workflow — the same wrapper works in CI and prod.

## At a glance

| Destination | base_url | api_key | Example model ID |
| --- | --- | --- | --- |
| GitHub Models (retiring) | https://models.github.ai/inference | GitHub PAT (models:read) | openai/gpt-4o-mini |
| OpenRouter | https://openrouter.ai/api/v1 | OpenRouter key | openai/gpt-4o-mini |
| OpenAI (direct) | (omit — SDK default) | OpenAI key | gpt-4o-mini |
| Anthropic | https://api.anthropic.com/v1/ | Anthropic key | claude model ID |
| Moonshot Kimi | https://api.moonshot.ai/v1 | Moonshot key | kimi-k2.7-code |
| Local Ollama | http://localhost:11434/v1 | ollama (ignored) | llama3.3 |

## By the numbers

- **3 lines** — the whole diff to switch providers once base_url + key + model live in env vars
- **15 min** — empty-workflow-to-working-call on a replacement, because the request shape never changes
- **July 16 & 23** — brownouts that will fail your call early — test the swap before them, not after
- **models.github.ai** — the string to grep for across your repo, including .github/workflows
- **localhost:11434/v1** — the local Ollama base URL that keeps dev + CI at zero per-token cost

GitHub Models is [fully retired on July 30, 2026](https://github.blog/changelog/2026-07-01-github-models-is-being-fully-retired-on-july-30-2026/), with brownouts on July 16 and 23 that will break your calls early. The [decision of *where* to move](/posts/github-models-shutdown-where-to-move.html) is its own piece; this one is the mechanical part — the exact edit — and it's smaller than the deadline makes it feel.
Here's why: GitHub Models implemented the **OpenAI Chat Completions API**. So does every replacement. Your actual `create()` calls don't change at all. You change *where the client points* and *how it authenticates*. That's the entire migration.
1. What you're replacing
The GitHub Models call looks like this — an OpenAI SDK client aimed at the GitHub endpoint, authenticated with a token that carries the `models:read` permission:
```
from openai import OpenAI
import os

client = OpenAI(
    base_url="https://models.github.ai/inference",
    api_key=os.environ["GITHUB_TOKEN"],   # a PAT with models:read
)

resp = client.chat.completions.create(
    model="openai/gpt-4o-mini",
    messages=[{"role": "user", "content": "ping"}],
)
```
Everything below the `client = ...` line survives untouched. You are only editing the two arguments to `OpenAI(...)` and the `model` string.
2. The swaps, one edit each
Each destination is the same three-part change: **base URL, key, model ID.**
Destination`base_url``api_key`Model ID**[OpenRouter](/stack/openrouter)**`https://openrouter.ai/api/v1`OpenRouter key`openai/gpt-4o-mini`**OpenAI (direct)***(omit — SDK default)*OpenAI key`gpt-4o-mini`**Anthropic**`https://api.anthropic.com/v1/`Anthropic keya `claude` model ID**Moonshot Kimi**`https://api.moonshot.ai/v1`Moonshot key`kimi-k2.7-code`**Local Ollama**`http://localhost:11434/v1``"ollama"` (ignored)`llama3.3`
[OpenRouter](/posts/tool-highlight-openrouter-one-api-every-model.html) is the smallest diff because it keeps the *namespaced* model IDs (`openai/gpt-4o-mini`) and the many-models-one-URL shape you're losing:
```
client = OpenAI(
    base_url="https://openrouter.ai/api/v1",
    api_key=os.environ["OPENROUTER_API_KEY"],
)
# model="openai/gpt-4o-mini" — unchanged
```
Going [local with Ollama](/posts/ollama-vs-lm-studio-vs-jan.html) keeps dev and CI at zero per-token cost; the `api_key` is required by the SDK but ignored by the server:
```
client = OpenAI(
    base_url="http://localhost:11434/v1",
    api_key="ollama",
)
# model="llama3.3" (after: ollama pull llama3.3)
```
3. Do it once: put the endpoint behind one env var
> The migration is easy because the format is shared. Make the *next* one free by never hard-coding the endpoint again — read it from the environment and route every call through one client.

Instead of editing code per provider, read all three moving parts from the environment and build a single shared client:
```
# llm.py — import this everywhere, construct the client nowhere else
from openai import OpenAI
import os

client = OpenAI(
    base_url=os.environ.get("LLM_BASE_URL") or None,  # None → OpenAI default
    api_key=os.environ["LLM_API_KEY"],
)
MODEL = os.environ["LLM_MODEL"]
```
```
from llm import client, MODEL

resp = client.chat.completions.create(
    model=MODEL,
    messages=[{"role": "user", "content": "ping"}],
)
```
Now switching providers is editing **three environment variables** — no code in the diff, no logic redeployed. This is the same discipline behind a [provider-agnostic agent](/posts/provider-agnostic-ai-agents.html): make the model vendor a variable, not a constant. Pair it with real [error handling and fallbacks](/posts/how-to-handle-llm-api-errors-retries-and-fallbacks.html) and one dead provider stops being an outage.
4. Check CI — GitHub Models is hiding in your workflows
The trap: GitHub Actions injects `GITHUB_TOKEN` automatically, so a workflow step can call the inference API with **no explicit key in the YAML.** That usage is invisible until July 30 kills it. Before the brownouts, grep the whole repo — including `.github/workflows` — for the two fingerprints:
```
grep -rn "models.github.ai\|models:read" . --include="*.py" --include="*.js" --include="*.yml" --include="*.yaml"
```
For each hit: add the new provider's key as an **Actions secret**, set `LLM_BASE_URL`, `LLM_API_KEY`, and `LLM_MODEL` in the job's `env:`, and the wrapper from step 3 runs unchanged in CI. Test it against the endpoint *now* — the [July 16 brownout](https://github.blog/changelog/2026-07-01-github-models-is-being-fully-retired-on-july-30-2026/) is a much better place to discover a broken workflow than the hard cutoff on the 30th.
That's the whole job: two lines to point somewhere new, three env vars to never do it again, one grep so CI doesn't ambush you.

## FAQ

### Do I have to rewrite my model calls to migrate?

No. GitHub Models implemented the OpenAI Chat Completions API, so your client.chat.completions.create(...) calls stay identical. You change only the base_url and api_key you construct the client with, and the model ID string. That's why the whole migration is a 15-minute edit rather than a project — the request/response shape doesn't change across any of the OpenAI-compatible destinations.

### What was the GitHub Models setup I'm replacing?

An OpenAI SDK client pointed at base_url='https://models.github.ai/inference', authenticated with a GitHub PAT (or the Actions GITHUB_TOKEN) carrying the models:read permission, calling a namespaced model like 'openai/gpt-4o-mini'. Anything matching that pattern stops working on July 30, 2026 — and will fail during the July 16 and 23 brownouts as a preview.

### Which replacement needs the fewest changes?

OpenRouter, because it keeps the namespaced model IDs (e.g. 'openai/gpt-4o-mini') and the 'many models, one endpoint' shape — you change base_url to 'https://openrouter.ai/api/v1' and swap the key. A direct provider is just as few edits but pins you to one vendor's model IDs. Both are a two-line diff.

### How do I stop this from happening again?

Don't hard-code the endpoint. Read LLM_BASE_URL, LLM_API_KEY, and LLM_MODEL from environment variables, build one shared client from them, and import that client everywhere. The next time a provider dies or you find a cheaper one, you edit three env vars and redeploy — no code touches the diff. This works precisely because every provider here speaks the same OpenAI format.

### I might be using GitHub Models in CI without realizing it — how do I check?

Grep your whole repo (including .github/workflows) for 'models.github.ai' and 'models:read'. GitHub Actions injects GITHUB_TOKEN automatically, so workflow steps could be calling the inference API with no explicit key in sight. For each hit, add the new provider's key as an Actions secret and set the LLM_* env vars in the job. The same wrapper you use in production runs unchanged in CI.

### Can I keep costs at zero the way GitHub Models did?

For development and CI, yes — point LLM_BASE_URL at a local Ollama server (base_url 'http://localhost:11434/v1', api_key 'ollama') and pull a small model. Per-token cost is zero; you trade it for local hardware. Because it's the same env-var switch, you can run Ollama locally and a hosted provider in production with identical code.
