Documented steps
POST http://localhost:11434/api/generate with JSON body {"model": "llama3.2", "prompt": "Why is the sky blue?", "stream": false}. model is required; the name follows model:tag format (tag defaults to :latest).
With stream:false you get a single JSON object: {"model", "created_at", "response": "<full text>", "done": true, "done_reason": "stop", "context": [...], plus stats fields}.
Read the stats from the final object: total_duration, load_duration, prompt_eval_count, prompt_eval_duration, eval_count, eval_duration. All durations are nanoseconds.
Compute tokens/sec as eval_count / eval_duration * 1e9.
Optionally pass a system string (overrides the Modelfile SYSTEM), and options object for sampler params (e.g. {"temperature": 0, "seed": 42}) at request time.
Known gotchas
If you omit "stream": false the endpoint streams newline-delimited JSON objects, not a single object — a naive json.loads of the whole body fails.
All duration fields are nanoseconds, not milliseconds.
The context field (conversational memory for /api/generate) is deprecated; use /api/chat with a messages array for multi-turn instead.
raw:true bypasses the prompt template (you must supply the fully templated prompt yourself) and no context is returned in raw mode.
