Switch in one line

Both models live behind Railwail's OpenAI-compatible endpoint. Replace the model string and you are done.

JavaScript / TypeScript
import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.RAILWAIL_API_KEY,
  baseURL: "https://railwail.com/v1",
});

// Before — using olmOCR
let r = await client.chat.completions.create({
  model: "lucataco/olmocr",
  messages: [{ role: "user", content: "Hello" }],
});

// After — switched to BLIP
r = await client.chat.completions.create({
  model: "salesforce/blip",
  messages: [{ role: "user", content: "Hello" }],
});
Python
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["RAILWAIL_API_KEY"],
    base_url="https://railwail.com/v1",
)

# Before — using olmOCR
r = client.chat.completions.create(
    model="lucataco/olmocr",
    messages=[{"role": "user", "content": "Hello"}],
)

# After — switched to BLIP
r = client.chat.completions.create(
    model="salesforce/blip",
    messages=[{"role": "user", "content": "Hello"}],
)

Which one wins for...

Quick verdicts derived from public specs. Always validate on your own workload.

Coding
olmOCR

Higher coding category match or larger context wins.

Writing
olmOCR

Bigger context window helps maintain long-form coherence.

Long documents
olmOCR

The larger context window is the deciding factor.

Vision
Tie

Multimodal/vision support is required for image inputs.

Real-time chat
Tie

Lower average latency wins for interactive UX.

Cost-sensitive
Tie

The model with the lower input-token price wins.

Frequently asked questions

Which is cheaper, olmOCR or BLIP?
olmOCR and BLIP cannot be compared on per-token price: at least one of them has no per-token price listed (it is priced per run or not yet priced). See each model page for its current price.
Which has more context, olmOCR or BLIP?
olmOCR and BLIP have similar context windows (— vs —).
Is olmOCR better than BLIP for coding?
For coding-heavy workloads we lean toward olmOCR on this comparison — it scores higher on the relevant heuristics (category, tags, or context window). Both models are usable for code via Railwail's OpenAI-compatible endpoint, so the safest path is to A/B test on your own prompts.
Can I use both olmOCR and BLIP via Railwail?
Yes. Both olmOCR and BLIP are accessible through a single Railwail API key and the OpenAI-compatible /v1/chat/completions endpoint. You only change the "model" parameter to switch between them — no SDK swap, no separate billing.
How do I switch from olmOCR to BLIP?
Replace the model identifier "lucataco/olmocr" with "salesforce/blip" in your request payload. Everything else — API key, base URL, request shape — stays the same. See the code example on this page for the exact one-line change.
