+PARAMETER num_ctx 65536 # Or higher if supported/needed. Maximize context.
+PARAMETER temperature 0.25 # Low for precision, but slightly higher than 0.1/0.2 for minor flexibility
+PARAMETER top_p 0.9      # Focuses on probable tokens, cutting off the long tail (less likely than top_p=1)
+PARAMETER top_k 40       # Further restricts sampling pool (often works well with top_p)
+PARAMETER repeat_penalty 1.1 # Mild penalty to discourage nonsensical loops, but allows necessary code repetition.
+PARAMETER num_keep 1024   # Keep initial instructions/context
+PARAMETER num_predict 16384 # Generous prediction length for substantial code blocks
