Non-tool basics all 200: chat, max_completion_tokens, system role, sampling params, SSE streaming (content deltas, usage chunk, [DONE]), json_schema (valid JSON matching schema) and json_object. Array-shaped message content is REJECTED with HTTP 500 'Request processing failed: text.charCodeAt is not a function' — same class of quirk as Cloudflare (PR #1587); messageContentFormat is set to 'string' and vision is false because the vision probe sends array parts and hits the identical 500. Tool calling does NOT work despite HTTP 200: morph-v3-large echoes the call as literal '<tool_call>{...}</tool_call>' text in message.content, and morph-v3-fast ignores the tools parameter and returns unrelated generated text (Python source) with finish_reason=length. tools and toolsWithStreaming are declared false on that basis; tools_plus_schema returning 200 is not evidence of structuredOutputWithTools since tools do not actually work. structuredOutput is true and strong (schema-conformant JSON, json_object accepted). The GET /v1/models roster lists 22 ids (morph-v3-fast, morph-v3-large, auto, morph-compactor, morph-warp-grep-v2.1, and passthrough ids for GLM/DeepSeek/Kimi/Qwen/MiniMax/Gemma/computer-use), but a deliberately invalid model name on /chat/completions came back 'is not served by this endpoint; accepted models: morph-v0, morph-v2, morph-v3-fast, morph-v3-large' — none of those other 18 roster ids were live-verified against chat/completions, so only the two confirmed working chat models are catalogued; context window (262144) and max output tokens (131072) for both come from Morph's public model metadata (https://www.morphllm.com/api/models/json), which also supplied pricing. Morph is a code-application (Fast Apply) specialist, not a general chat vendor: morph-v3-large is catalogued as the default because it is the general-purpose one of the pair, while morph-v3-fast is purpose-built for edit application rather than open-ended conversation."
