Line range hint 1-90: Consider adding model capability documentation

While the model metadata is well-structured, it would be helpful to include documentation about each model's specific capabilities (e.g., code generation, instruction following, etc.) to aid in model selection.

Would you like me to propose a documentation structure for the model capabilities?

src/Azure/src/AzureOpenAiChatModel.cs (3)

47-47: Fix typo in method name

The method name contains a typo: ExtarctTools should be ExtractTools.

-        List<ChatTool> tools = ExtarctTools(request);
+        List<ChatTool> tools = ExtractTools(request);

256-261: Enhance tool name parsing validation

While using ElementAtOrDefault provides some safety, consider adding explicit validation for the expected format to provide more meaningful error messages.

-                var toolNameAndId = message.ToolName?.Split(':') ??
-                                    throw new ArgumentException("Invalid functionCall name and id string");
-
-                var toolCall = OpenAI.Chat.ChatToolCall.CreateFunctionToolCall(toolNameAndId.ElementAtOrDefault(1),
-                        toolNameAndId.ElementAtOrDefault(0),
-                        BinaryData.FromString(message.Content));
+                var toolNameAndId = message.ToolName?.Split(':') ??
+                    throw new ArgumentException("Tool name is required");
+                
+                if (toolNameAndId.Length != 2)
+                {
+                    throw new ArgumentException($"Invalid tool name format. Expected 'name:id' but got '{message.ToolName}'");
+                }
+                
+                var toolCall = OpenAI.Chat.ChatToolCall.CreateFunctionToolCall(

Line range hint 314-342: Implement required interface methods

Several critical methods are currently throwing NotImplementedException:

  • CountTokens overloads for token counting
  • TryCalculatePriceInUsd for price calculation

These methods are part of the implemented interfaces and should be properly implemented to avoid runtime exceptions.

Would you like help implementing these methods? I can provide implementations based on Azure OpenAI's token counting and pricing models.

59-59: LGTM! Improved code formatting

The removal of unnecessary whitespace improves code readability while maintaining the method's functionality.


Line range hint 37-37: Great use of C# 12's collection expressions!

The initialization of ToolCalls using = [] is a clean and efficient way to ensure the property is never null. This aligns well with the class's overall null-safe design pattern.

src/DeepInfra/src/DeepInfraModelProvider.cs (3)

25-25: LGTM: Price update for MythomaxL213B model

The price adjustment from 1.0e-7 to 8e-8 USD per token aligns with the changes mentioned in the AI summary and appears to be part of a routine pricing update.


33-33: Verify pricing consistency across Qwen model family

The new Qwen257BInstruct model's pricing (6e-8 USD) and context length (32768) are consistent with other Qwen models in the same series (e.g., Qwen27BInstruct).

✅ Verification successful

Pricing and context length are consistent within Qwen 7B models

The verification confirms that Qwen2.5-7B-Instruct's pricing (6e-8 USD) and context length (32768) match other 7B models in the DeepInfra provider:

  • Qwen2-7B-Instruct: 6e-8 USD, 32768 context
  • Qwen2.5-Coder-7B: 6e-8 USD, 32768 context
🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Verify consistency of pricing across Qwen models
rg "Qwen.*ToMetadata.*6[Ee]-8" --type cs

Length of output: 42


Script:

#!/bin/bash
# Search for all Qwen model metadata definitions to compare pricing
rg "Qwen.*ToMetadata" -A 1 --type cs

Length of output: 6455


15-17: Verify the context length for new models

The new models MetaLlama318BInstructTurbo and Qwen25Coder32BInstruct have been added with context lengths of 131072 and 32768 respectively. These values should be verified against the official DeepInfra documentation.

✅ Verification successful

Context lengths are consistent with model families

Based on the search results:

  • The context length of 131072 for Meta-Llama-3.1 models is consistent across the family (Meta-Llama-3.1-70B-Instruct, Meta-Llama-3.1-8B-Instruct all use 131072)
  • The context length of 32768 for Qwen models is consistent across all Qwen variants in both DeepInfra and Together providers (Qwen2-72B, Qwen1.5 series, Qwen2.5 series all use 32768)

The context lengths for both new models align with their respective model families' established patterns in the codebase.

99-99: LGTM! Good addition of performance tracking.

The stopwatch initialization is a valuable addition for monitoring the timing of streaming responses.


133-133: LGTM! Enhanced logging with timing information.

The addition of timing information to the logging statements will help with debugging and performance analysis of streaming responses.

Also applies to: 139-139


Line range hint 144-146: Investigate the commented-out delta equivalence assertion.

The commented assertion suggests there might be inconsistencies in how different providers handle streaming deltas. This should be investigated to ensure consistent behavior across providers.

Let's analyze the delta handling across different providers:

src/Azure/src/AzureOpenAiChatModel.cs (2)

Line range hint 147-157: LGTM: Robust tool calls handling

The implementation properly handles tool calls with appropriate null checking and field mapping.


Line range hint 274-312: LGTM: Clean implementation with modern C# features

The method effectively handles both tool calls and regular messages, making good use of C# 12's collection expressions.

src/DeepInfra/src/Predefined/AllModels.cs (4)

18-20: LGTM! MetaLlama318BInstructTurboModel implementation

The class follows the established patterns and conventions for model implementations.


28-30: LGTM! Qwen25Coder32BInstructModel implementation

The class follows the established patterns and conventions for model implementations.


108-110: LGTM! Qwen257BInstructModel implementation

The class follows the established patterns and conventions for model implementations.


18-20: Verify model IDs exist in DeepInfraModelIds

Let's ensure the model IDs used by the new classes are properly defined.

Also applies to: 28-30, 108-110

✅ Verification successful

Model IDs are properly defined in DeepInfraModelIds

The verification shows that all referenced model IDs (MetaLlama318BInstructTurbo, Qwen25Coder32BInstruct, and Qwen257BInstruct) are properly defined in src/DeepInfra/src/DeepInfraModelIds.cs and are correctly used in both the model provider and predefined model classes.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Check if the model IDs are defined in DeepInfraModelIds

# Search for model ID definitions
