Hermes Agent

ollama launch hermes

Hermes learns with you, automatically creating skills to better serve your workflows. Great for research and engineering tasks.

What's Changed

• Gemma 4 on MLX. Added support for running Gemma 4 via MLX on Apple Silicon, including a text-only MLX runtime for the model. The MLX backend also picked up mixed-precision quantization, better capability detection, and a batch of new op wrappers (Conv2d, Pad, activations, trig, masked SDPA, and RoPE-with-freqs).
• Hermes and GitHub Copilot CLI in ollama launch. Added both integrations, which can now be configured in one command alongside the rest of the supported coding agents.
• OpenCode moved to inline config. ollama launch opencode now writes its config inline rather than to a separate file, matching how other integrations are handled.
• ollama launch no longer rewrites config when nothing changed. Pressing → on a configured multi-model integration, or passing --model with the current primary, used to trigger a confirmation prompt and rewrite both the editor's config file and config.json. Now it's a no-op when the resolved model list matches what's already saved.
• Fixed ollama launch openclaw --yes so it correctly skips the channels configuration step, so non-interactive setups complete cleanly.
• Restored the Gemma 4 nothink renderer with the e2b-style prompt.
• Fixed the Gemma 4 compiler error that was breaking Metal builds.
• Fixed macOS cross-compiles so they no longer trigger generate, which was breaking cmake builds on some Xcode versions.
• Quieted cgo builds by suppressing deprecated warnings during go build.
