Remove unused detector weights (-30.6 GB)

Text detection moved to the Grok LLM judge in the detect-text edge function, so the Falcon-7B Binoculars pair and both text RoBERTas are no longer loaded or cached by the worker (image detection-v20-755af5c drops them from REQUIRED_MODELS / CACHE_SYMLINK_MAP).

sdxl-detector and AI-image-detector were replaced by haywoodsloan and Smogy in detector.py v6; they survive only in comments.

-class FalconConfig(PretrainedConfig):
-    r"""
-    This is the configuration class to store the configuration of a [`FalconModel`]. It is used to instantiate a Falcon
-    model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
-    defaults will yield a similar configuration to that of the
-    [tiiuae/falcon-7b](https://huggingface.co/tiiuae/falcon-7b) architecture.
-
-    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
-    documentation from [`PretrainedConfig`] for more information.
-
-
-    Args:
-        vocab_size (`int`, *optional*, defaults to 65024):
-            Vocabulary size of the Falcon model. Defines the number of different tokens that can be represented by the
-            `inputs_ids` passed when calling [`FalconModel`]
-        hidden_size (`int`, *optional*, defaults to 4544):
-            Dimension of the hidden representations.
-        num_hidden_layers (`int`, *optional*, defaults to 32):
-            Number of hidden layers in the Transformer decoder.
-        num_attention_heads (`int`, *optional*, defaults to 71):
-            Number of attention heads for each attention layer in the Transformer encoder.
-        initializer_range (`float`, *optional*, defaults to 0.02):
-            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
-        use_cache (`bool`, *optional*, defaults to `True`):
-            Whether the model should return the last key/values attentions (not used by all models). Only relevant if
-            `config.is_decoder=True`.
-        layer_norm_epsilon (`float`, *optional*, defaults to 1e-5):
-            The epsilon used by the layer normalization layers.
-        hidden_dropout (`float`, *optional*, defaults to 0.0):
-            The dropout probability for MLP layers.
-        attention_dropout (`float`, *optional*, defaults to 0.0):
-            The dropout probability for attention layers.
-        num_kv_heads (`int`, *optional*):
-            Number of key-value heads to use per attention layer. If unset, defaults to the same value as
-            `num_attention_heads`.
-        alibi (`bool`, *optional*, defaults to `False`):
-            Whether to use ALiBi positional biases during self-attention.
-        new_decoder_architecture (`bool`, *optional*, defaults to `False`):
-            Whether to use the new (Falcon-40B) decoder architecture. If `True`, the `multi_query` and `parallel_attn`
-            arguments are ignored, as the new decoder always uses parallel attention.
-        multi_query (`bool`, *optional*, defaults to `True`):
-            Whether to use multi-query attention in the decoder. Ignored when `new_decoder_architecture` is `True`.
-        parallel_attn (`bool`, *optional*, defaults to `True`):
-            Whether to compute attention in parallel with the feedforward layer. If False, they are consecutive
-            instead, as in the original Transformer architecture. Ignored when `new_decoder_architecture` is `True`.
-        bias (`bool`, *optional*, defaults to `False`):
-            Whether to use bias on Linear layers.
-        bos_token_id (`int`, *optional*, defaults to 11):
-            The id of the "beginning-of-sequence" token.
-        eos_token_id (`int`, *optional*, defaults to 11):
-            The id of the "end-of-sequence" token.
-
-    Example:
-
-    ```python
-    >>> from transformers import FalconModel, FalconConfig
-
-    >>> # Initializing a small (2-layer) Falcon configuration
-    >>> configuration = FalconConfig(num_hidden_layers=2)
-
-    >>> # Initializing a model from the small configuration
-    >>> model = FalconModel(configuration)

-    This model inherits from [`PreTrainedModel`]. Check the superclass documentation for the generic methods the

-
-    This model is also a PyTorch [torch.nn.Module](https://pytorch.org/docs/stable/nn.html#torch.nn.Module) subclass.
-    Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage
-    and behavior.
-
-    Parameters:
-        config ([`FalconConfig`]): Model configuration class with all the parameters of the model.
-            Initializing with a config file does not load the weights associated with the model, only the

-            (`sequence_length` of input past key value states). Indices of input sequence tokens in the vocabulary.
-
-            If `past_key_values` is used, only `input_ids` that do not have their past calculated should be passed as
-            `input_ids`.
-
-            Indices can be obtained using [`AutoTokenizer`]. See [`PreTrainedTokenizer.encode`] and
-            [`PreTrainedTokenizer.__call__`] for details.

-        past_key_values (`Tuple[Tuple[torch.Tensor]]` of length `config.num_hidden_layers`):
-            Contains precomputed hidden-states (key and values in the attention blocks) as computed by the model (see
-            `past_key_values` output below). Can be used to speed up sequential decoding. The `input_ids` which have
-            their past given to this model should not be passed as `input_ids` as they have already been computed.
-
-            Each element of `past_key_values` is a tuple (past_key, past_value):
-            - past_key: [batch_size * num_heads, head_dim, kv_length]
-            - past_value: [batch_size * num_heads, kv_length, head_dim]
-        attention_mask (`torch.FloatTensor` of shape `(batch_size, sequence_length)`, *optional*):

-            Mask to nullify selected heads of the self-attention modules. Mask values selected in `[0, 1]`:
-
-            - 1 indicates the head is **not masked**,
-            - 0 indicates the head is **masked**.
-
-        inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
-            Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This
-            is useful if you want more control over how to convert `input_ids` indices into associated vectors than the
-            model's internal embedding lookup matrix.
-
-            If `past_key_values` is used, optionally only the last `inputs_embeds` have to be input (see

-        use_cache (`bool`, *optional*):
-            If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
-            `past_key_values`).
-        output_attentions (`bool`, *optional*):

-class FalconConfig(PretrainedConfig):
-    r"""
-    This is the configuration class to store the configuration of a [`FalconModel`]. It is used to instantiate a Falcon
-    model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
-    defaults will yield a similar configuration to that of the
-    [tiiuae/falcon-7b](https://huggingface.co/tiiuae/falcon-7b) architecture.
-
-    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
-    documentation from [`PretrainedConfig`] for more information.
-
-
-    Args:
-        vocab_size (`int`, *optional*, defaults to 65024):
-            Vocabulary size of the Falcon model. Defines the number of different tokens that can be represented by the
-            `inputs_ids` passed when calling [`FalconModel`]
-        hidden_size (`int`, *optional*, defaults to 4544):
-            Dimension of the hidden representations.
-        num_hidden_layers (`int`, *optional*, defaults to 32):
-            Number of hidden layers in the Transformer decoder.
-        num_attention_heads (`int`, *optional*, defaults to 71):
-            Number of attention heads for each attention layer in the Transformer encoder.
-        initializer_range (`float`, *optional*, defaults to 0.02):
-            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
-        use_cache (`bool`, *optional*, defaults to `True`):
-            Whether the model should return the last key/values attentions (not used by all models). Only relevant if
-            `config.is_decoder=True`.
-        layer_norm_epsilon (`float`, *optional*, defaults to 1e-5):
-            The epsilon used by the layer normalization layers.
-        hidden_dropout (`float`, *optional*, defaults to 0.0):
-            The dropout probability for MLP layers.
-        attention_dropout (`float`, *optional*, defaults to 0.0):
-            The dropout probability for attention layers.
-        num_kv_heads (`int`, *optional*):
-            Number of key-value heads to use per attention layer. If unset, defaults to the same value as
-            `num_attention_heads`.
-        alibi (`bool`, *optional*, defaults to `False`):
-            Whether to use ALiBi positional biases during self-attention.
-        new_decoder_architecture (`bool`, *optional*, defaults to `False`):
-            Whether to use the new (Falcon-40B) decoder architecture. If `True`, the `multi_query` and `parallel_attn`
-            arguments are ignored, as the new decoder always uses parallel attention.
-        multi_query (`bool`, *optional*, defaults to `True`):
-            Whether to use multi-query attention in the decoder. Ignored when `new_decoder_architecture` is `True`.
-        parallel_attn (`bool`, *optional*, defaults to `True`):
-            Whether to compute attention in parallel with the feedforward layer. If False, they are consecutive
-            instead, as in the original Transformer architecture. Ignored when `new_decoder_architecture` is `True`.
-        bias (`bool`, *optional*, defaults to `False`):
-            Whether to use bias on Linear layers.
-        bos_token_id (`int`, *optional*, defaults to 11):
-            The id of the "beginning-of-sequence" token.
-        eos_token_id (`int`, *optional*, defaults to 11):
-            The id of the "end-of-sequence" token.

-    This model inherits from [`PreTrainedModel`]. Check the superclass documentation for the generic methods the

-
-    This model is also a PyTorch [torch.nn.Module](https://pytorch.org/docs/stable/nn.html#torch.nn.Module) subclass.
-    Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage
-    and behavior.
-
-    Parameters:
-        config ([`FalconConfig`]): Model configuration class with all the parameters of the model.
-            Initializing with a config file does not load the weights associated with the model, only the

-    Args:

-            (`sequence_length` of input past key value states). Indices of input sequence tokens in the vocabulary.
-
-            If `past_key_values` is used, only `input_ids` that do not have their past calculated should be passed as
-            `input_ids`.
-
-            Indices can be obtained using [`AutoTokenizer`]. See [`PreTrainedTokenizer.encode`] and
-            [`PreTrainedTokenizer.__call__`] for details.

-            [What are input IDs?](../glossary#input-ids)
-        past_key_values (`Tuple[Tuple[torch.Tensor]]` of length `config.num_hidden_layers`):
-            Contains precomputed hidden-states (key and values in the attention blocks) as computed by the model (see
-            `past_key_values` output below). Can be used to speed up sequential decoding. The `input_ids` which have
-            their past given to this model should not be passed as `input_ids` as they have already been computed.
-
-            Each element of `past_key_values` is a tuple (past_key, past_value):
-            - past_key: [batch_size * num_heads, head_dim, kv_length]
-            - past_value: [batch_size * num_heads, kv_length, head_dim]
-        attention_mask (`torch.FloatTensor` of shape `(batch_size, sequence_length)`, *optional*):
-            Mask to avoid performing attention on padding token indices. Mask values selected in `[0, 1]`:

-        head_mask (`torch.FloatTensor` of shape `(num_heads,)` or `(num_layers, num_heads)`, *optional*):
-            Mask to nullify selected heads of the self-attention modules. Mask values selected in `[0, 1]`:
-
-            - 1 indicates the head is **not masked**,
-            - 0 indicates the head is **masked**.
-
-        inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
-            Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This
-            is useful if you want more control over how to convert `input_ids` indices into associated vectors than the
-            model's internal embedding lookup matrix.
-
-            If `past_key_values` is used, optionally only the last `inputs_embeds` have to be input (see

-        use_cache (`bool`, *optional*):
-            If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
-            `past_key_values`).
-        output_attentions (`bool`, *optional*):
-            Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
-            tensors for more detail.
-        output_hidden_states (`bool`, *optional*):
