EvoScientist v0.2.4 β Claude Opus 5, new Geminis & the Anthropic-protocol channel
G'Day! v0.2.4 is a model-catalog and protocol-compat release: Claude Opus 5 and two new Gemini flashes join the lineup, and Kimi K3 now works end-to-end over Anthropic-protocol channels β including the Kimi For Coding subscription endpoint β after a deep dive into how strict Anthropic-compatible edges validate requests.
π§ New models
- Claude Opus 5 β selectable in
EvoSci onboardand/modelon Anthropic (nativeclaude-opus-5) and OpenRouter (anthropic/claude-opus-5, fast variant included), with 1M context. - Claude 5-series thinking fix β
claude-opus-5/claude-sonnet-5on the direct Anthropic API now get adaptive thinking; the auto-config previously fell through to the legacybudget_tokensshape, which 5-series models reject with HTTP 400. - Gemini 3.6 Flash & Gemini 3.5 Flash Lite β selectable on Google (native) and OpenRouter, 1M context.
π§ Kimi K3 over Anthropic-protocol channels
K3 runs with thinking always on, and strict Anthropic-compatible edges (Moonshot's Kimi For Coding endpoint, OpenRouter's Anthropic schema) reject several things the default request path produced. v0.2.4 makes the whole surface work:
- Structured output no longer 400s β
with_structured_outputon K3-class models routes throughoutput_config.format(json_schema) instead of a forced tool call, which mandatory-thinking endpoints reject (tool_choice 'specified' is incompatible with thinking enabled). This also fixes the >20-tools tool-selector on these channels. - Cross-provider history replay β switching a session from an OpenAI-compatible provider (Qwen, DeepSeek, β¦) to an Anthropic-protocol endpoint no longer 400s: foreign
reasoning_contentblocks are stripped before send. Native Claude benefits from the same protection. - Multi-turn thinking preserved β K3's thinking blocks are kept on replay (Kimi backends require them on tool-call turns), and streamed thinking that arrives without a
signature_deltagets its signature defaulted β fixing a second-turn 400 after any streamed reply. - Thinking declared like the official client β K3-class models on Anthropic-routed providers now declare
thinking: enabled(with a matchingmax_tokensfloor), mirroring Moonshot's own kimi-code client.
π Fixes
- Interrupted tool-call history repaired β resuming after a mid-tool-call interruption no longer corrupts the conversation history (#366).
- Skill installs scrub host paths β
skill_manageroutput no longer leaks absolute host paths, and batch installs are guarded (#377). - Multi-turn reasoning context for ChatGPT OAuth β the codex proxy Responses API path now defaults
reasoning.context, so GPT-5.x keeps its reasoning across turns (#380). - Quieter logs β missing async-subagent tools log at DEBUG instead of WARNING (#378).
π§© Dependencies
- openrouter pinned
<0.11β 0.11.x introduced SSE streaming regressions (teardown noise, mid-turnReadTimeout); pinned until fixed upstream (#373).
