		"ClassificationOutputTransform": {

				"label": {
					"type": "string",
					"description": "The predicted class label."

		"GenerationParameters": {
			"title": "GenerationParameters",
			"type": "object",
			"properties": {
				"temperature": {
					"type": "number",
					"description": "The value used to modulate the next token probabilities."
				},
				"top_k": {
					"type": "integer",
					"description": "The number of highest probability vocabulary tokens to keep for top-k-filtering."
				},
				"top_p": {
					"type": "number",
					"description": "If set to float < 1, only the smallest set of most probable tokens with probabilities that add up to top_p or higher are kept for generation."
				},
				"typical_p": {
					"type": "number",
					"description": " Local typicality measures how similar the conditional probability of predicting a target token next is to the expected conditional probability of predicting a random token next, given the partial text already generated. If set to float < 1, the smallest set of the most locally typical tokens with probabilities that add up to typical_p or higher are kept for generation. See [this paper](https://hf.co/papers/2202.00666) for more details."
				},
				"epsilon_cutoff": {
					"type": "number",
					"description": "If set to float strictly between 0 and 1, only tokens with a conditional probability greater than epsilon_cutoff will be sampled. In the paper, suggested values range from 3e-4 to 9e-4, depending on the size of the model. See [Truncation Sampling as Language Model Desmoothing](https://hf.co/papers/2210.15191) for more details."
				},
				"eta_cutoff": {
					"type": "number",
					"description": "Eta sampling is a hybrid of locally typical sampling and epsilon sampling. If set to float strictly between 0 and 1, a token is only considered if it is greater than either eta_cutoff or sqrt(eta_cutoff) * exp(-entropy(softmax(next_token_logits))). The latter term is intuitively the expected next token probability, scaled by sqrt(eta_cutoff). In the paper, suggested values range from 3e-4 to 2e-3, depending on the size of the model. See [Truncation Sampling as Language Model Desmoothing](https://hf.co/papers/2210.15191) for more details."

				"max_length": {
					"type": "integer",
					"description": "The maximum length (in tokens) of the generated text, including the input."

					"type": "integer",
					"description": "The maximum number of tokens to generate. Takes precedence over max_length."

					"type": "boolean",
					"description": "Whether to use sampling instead of greedy decoding when generating new tokens."
