Release history for TachiBot MCP — new models, tools, and orchestration capabilities.

v2.34.0

Sep 14, 2026

New models

GPT-6 Astra is the default, and qwq_reason works again

GPT-6 Astra is the OpenAI default. Backs openai_reason, openai_brainstorm, openai_code_review, spec_writer, tachi and the GPT reviewers, falling back to sol, then terra.
GPT-6 goes through the Responses API. No temperature; the none/minimal efforts Astra rejects are sent as low.
qwq_reason is back. Now on qwen3.8-27b after OpenRouter retired qwq-32b. Same name and parameters.

Bug fixes

Reliability at every boundary

grok_search actually searches. Moved to grok-4.6; tests assert a real web_search_call and citation.
Protocol-safe diagnostics. stdout stays reserved for JSON-RPC.
create_workflow no longer clobbers existing files without overwrite: true.
