·2026.04.15 23:31

Key point

GLM 5.1 on Ollama Cloud feels much slower than on Windsurf and has unstable tool integration.

Details

GLM 5.1, first tried on Windsurf with free credits, felt responsive and had good comprehension, but using it via a subscription on Ollama Cloud turned out much less satisfying than expected.

The issues can be summarized as follows.

  • Very slow
  • Stalling occurs mid-task
  • Frequent timeouts
  • Doesn't properly understand tools like Serena MCP and filesystem

The user tested this across Claude Code, Codex, and the Continue.dev plugin (VS Code), and while each environment had its own quirks, Claude was noted as the most stable among them.

In conclusion, even with the same model, perceived performance on Ollama Cloud was much worse than on Windsurf, and it was speculated that a significant part of the problem may be related to behavior on the Ollama server side.
