Verity Mod Ollama Local AI Setup

What the Ollama option changes

Ollama runs a language model service on your computer. Verity JE can send prompts to that local service instead of using the Groq cloud path. This removes the need for a Groq credential and can keep model inference local, but it adds hardware, storage, model, service, and configuration requirements.

Use Ollama only after the base Java mod works. Minecraft should launch with the correct loader, Verity should load in a clean profile, and the documented in-game interaction should appear. If the game crashes before the title screen, solve the loader or dependency problem first.

Check whether local inference fits your computer

Local models use disk space, memory, processor or graphics resources, and power. Larger models generally need more resources and may answer more slowly on modest hardware. The right model is one that Ollama can load reliably while Minecraft is also running.

Before installing a large model, review the current Ollama documentation and the model’s published size. Keep enough free disk space for the download and enough memory headroom for both applications. A system that can run Minecraft smoothly may still struggle when a model and a modded game compete for memory.

Start with a smaller model supported by the current Verity instructions. The goal of the first test is a complete response, not maximum model quality. Once the connection is stable, you can compare models one at a time.

Install Ollama from its official source

Use the official Ollama documentation linked in the Sources section. Install the version for your operating system and follow its current service-start instructions. Avoid repackaged installers or bundles promising a preconfigured Verity model.

After installation, verify Ollama outside Minecraft. Open a terminal or the official interface, download the chosen model using the current Ollama command, and run a short prompt. The service and model must work independently before Verity can use them.

Record the exact model name displayed by Ollama, including any tag. Similar-looking names can identify different models or versions. “Model not found” often means Verity requests a name that is not installed, not that the mod itself failed.

Verify the local service

Ollama normally exposes a local HTTP service. Its documentation commonly uses http://localhost:11434 as the local base address. Confirm the current default in the official documentation and verify that the service is running before launching Minecraft.

“Localhost” means the same computer as the process making the request. If Minecraft runs in a virtual machine, container, remote desktop environment, or separate server, localhost may point to the wrong machine. Keep the first test on one computer. Remote exposure introduces firewall and security decisions that are outside the simplest Verity setup.

Do not open the Ollama service to the public internet merely to fix a local connection. A local firewall rule should be as narrow as the setup requires. Follow official Ollama guidance for any non-local deployment.

Configure Verity JE

Use the current configuration location shown by the Verity JE project or its maintainer-linked Ollama tutorial. Select the Ollama/local provider path. Enter the local service address only if the current setup asks for one, and enter the model name exactly as Ollama lists it.

Do not leave a stale Groq provider selected while testing Ollama. Choose one provider so an error can be attributed to one path. Restart the game or reload configuration as directed by the current maintainer instructions.

The guide does not prescribe a permanent config filename because mod releases can move settings. A copied path from an older tutorial may edit the wrong launcher instance or an obsolete option.

First end-to-end test

1. Start Ollama and confirm the model answers outside Minecraft.
2. Start the clean Verity JE profile.
3. Open a new test world.
4. Send one short text prompt.
5. Watch both the Minecraft log and Ollama output for the request.

A response in Ollama but not Minecraft suggests a Verity configuration or response-handling problem. No request reaching Ollama suggests the provider selection, endpoint, service availability, or firewall. A model-not-found response identifies the name or missing download. A very slow response may be resource pressure rather than a broken connection.

Wait for one request to finish. Sending many prompts can queue local work, consume more memory, and make the mod appear less responsive.

Common Ollama failures

Service is not running: the model may be installed but no process is listening. Start Ollama using the current operating-system instructions and verify again outside Minecraft.

Exact model is missing: list installed models. Copy the complete name and tag into Verity, or download the model the current project recommends.

Wrong endpoint: use the local address documented by Ollama and Verity. Watch for a changed port, an accidental https scheme on a plain local service, or a remote hostname copied from another tutorial.

Profile mismatch: confirm that the Verity configuration belongs to the launcher instance you actually start.

Memory pressure: close heavy applications, use a smaller model, lower other game resource demands, and observe operating-system memory rather than repeatedly reinstalling.

Firewall or isolation: verify that the Java process can reach the local service. In managed environments, follow network policy rather than disabling security controls.

Text before speech

Test text responses before microphone input or text-to-speech. A local model response proves that Ollama, the endpoint, model name, and Verity request path work. Voice features add operating-system permissions, input devices, speech recognition, audio output, and language behavior.

The Verity JE page notes that AI text can support multiple languages while speech-to-text and text-to-speech were tested in English. Use short English text during the first diagnosis. If text works and voice does not, keep the Ollama setup unchanged and troubleshoot the audio layer separately.

Privacy and security boundaries

Local inference can reduce the number of prompts sent to a cloud model, but it is not a blanket guarantee that the entire game session is offline or private. Review the behavior of Minecraft, the launcher, Verity, other mods, and update tools. Avoid placing passwords, private documents, or sensitive personal information in prompts.

Keep the Ollama service local unless you intentionally design and secure a remote deployment. Do not expose it through a router, public tunnel, or unrestricted network interface as a quick fix. Logs can still contain prompts and local paths, so inspect them before sharing.

Decide between Ollama and Groq

Choose Ollama when your machine can run an appropriate model and you prefer local inference. Choose Groq when local resource use or model management is impractical and you accept a cloud provider. Neither option fixes a wrong loader, missing dependency, or unsupported Minecraft version.

Keep a record of the working model name, Ollama version, service address, Minecraft version, loader, and Verity release. After any update, test Ollama alone, then Verity in a clean world, before returning to an important save.
