fix: bypass display_generation for OpenAI streaming to enable raw chunk output #1030
Conversation
…nk output This fix modifies Agent._start_stream() to handle OpenAI-style models with direct streaming that bypasses the display_generation UI, allowing users to get raw streaming chunks when stream=True. Key changes: - Replace self.chat() fallback with direct OpenAI client streaming - Add proper knowledge search and tool handling for OpenAI path - Use _build_messages helper for consistent message formatting - Yield raw chunks without display function interference - Add robust error handling with chat history rollback - Preserve fallback to simulated streaming on errors Fixes streaming behavior where chunks were wrapped in display_generation instead of being yielded directly to user code.

Summary of Changes
Hello @MervinPraison, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request significantly enhances the streaming experience for OpenAI-style models by implementing direct, raw chunk output. It moves away from a simulated streaming approach to leverage the native streaming capabilities of the OpenAI API, ensuring users receive real-time, unadulterated responses. The changes also integrate existing functionalities like knowledge search and tool handling into this new streaming path, while providing robust error handling and a fallback mechanism.
Highlights
- Direct OpenAI Streaming: I've updated the
_start_streammethod to directly utilize the OpenAI API's streaming capabilities for OpenAI-style models. This replaces the previous fallback toself.chat()and simulated streaming. - Raw Chunk Output: The core change ensures that raw streaming chunks from the OpenAI API are yielded directly to the user, bypassing any intermediate
display_generationUI wrapping. This provides true, real-time streaming output. - Enhanced OpenAI Integration: The new streaming path now properly handles knowledge search integration into the prompt, formats and includes tools for OpenAI API calls, and uses the
_build_messageshelper for consistent message formatting. - Robust Error Handling & Fallback: I've added a
try-exceptblock around the OpenAI streaming call. In case of an error, the chat history is rolled back, and the system gracefully falls back to the original simulated streaming behavior usingself.chat(). - New Test File: A new test script,
test_streaming_display_fix.py, has been added to validate the setup of the streaming infrastructure and confirm thatagent.start()returns a generator when streaming is enabled, using a mock model for testing.

Code Review
This pull request introduces a significant improvement by implementing true streaming for OpenAI models. The code is well-structured, including robust error handling with history rollback and a fallback to simulated streaming. My review focuses on reducing code duplication and improving the test script to ensure it correctly validates the intended behavior.

This test case is flawed. The try...except block will never catch an exception because calling a generator function (agent.start which returns _start_stream) only creates a generator object but does not execute its code. The code inside the generator is only executed when it's iterated over. As a result, the except block is currently unreachable code.
To fix this, you should consume the generator to trigger the underlying code that is expected to raise an exception for the mock model.

The if/else block for creating the OpenAI completion has duplicated code. The only difference is the presence of the tools parameter. This can be refactored to build a dictionary of parameters first, and then conditionally add the tools key if formatted_tools is not empty. This will make the code more concise and easier to maintain.
# Create streaming completion directly without display function
completion_args = {
"model": self.llm,
"messages": messages,
"temperature": kwargs.get('temperature', 0.2),
"stream": True
}
if formatted_tools:
completion_args["tools"] = formatted_tools

The fallback logic for simulated streaming is identical to the implementation that was removed from the else block in this PR. To improve maintainability and avoid code duplication, consider extracting this logic into a private helper method, for example _simulate_stream_from_response(self, response). This new method could then be called here in the except block.

Bug: OpenAI Streaming: Client Access and Tool Call Issues
The new OpenAI streaming implementation introduces two bugs:
- Incorrect Client Access: It attempts to access the OpenAI client via
self._openai_client.client, which is incorrect. It should useself._openai_client.sync_clientfor synchronous operations, consistent with existing codebase patterns, otherwise anAttributeErrorwill occur. - Missing Tool Call Handling: The streaming loop only processes
delta.contentand ignoresdelta.tool_calls. This prevents tool execution when tools are provided, breaking the agent's ability to use tools in streaming mode.

2040-2131: Well-implemented streaming enhancement with proper error handlingThe refactored
_start_streammethod successfully addresses the PR objective of bypassingdisplay_generationfor OpenAI streaming. The implementation includes:
- Proper knowledge augmentation (lines 2043-2051)
- Consistent tool handling (lines 2053-2057)
- Message building using the helper method (lines 2059-2061)
- Chat history management with rollback on errors (lines 2064-2075, 2117-2119)
- Direct streaming without display functions (lines 2086-2102)
The error handling with fallback to simulated streaming (lines 2120-2131) ensures graceful degradation.
test_streaming_display_fix.py (1)
14-57: Well-structured test for streaming infrastructure validationThe test effectively validates the streaming display bypass fix by:
- Checking agent creation with
stream=True- Verifying that

Global error logging should use theerror_logslist, and a callback system should be provided for real-time error reporting.
Context length exceptions should be handled with automatic retry logic.
Graceful degradation should be implemented for optional dependencies.

2040-2181: Excellent implementation of OpenAI streaming with comprehensive tool call support.The new streaming implementation successfully addresses the PR objectives by implementing true streaming for OpenAI-style models without
display_generationinterference. Key strengths include:
- Knowledge search integration (lines 2041-2050)
- Proper tool parameter handling and formatting (lines 2052-2057, 2082-2093)
- Direct streaming via OpenAI client without UI wrapper (lines 2085-2095)
- Complete tool call handling with accumulation and execution (lines 2110-2160)
- Robust error handling with chat history rollback (lines 2166-2169)
- Graceful fallback to simulated streaming (lines 2170-2180)
The implementation correctly handles both text content and tool calls in streaming responses, addressing the previous concern about missing tool call handling.
2086-2095: Code duplication issue successfully resolved.The implementation now uses the recommended dictionary approach to build completion arguments and conditionally adds tools, eliminating the code duplication that was flagged in previous reviews.
2166-2180: Robust error handling with graceful degradation implemented.The error handling implementation is comprehensive and follows best practices:
- Chat history rollback prevents inconsistent state (lines 2167-2169)
- Proper error logging for debugging (line 2169)
- Graceful fallback to simulated streaming ensures user gets response (lines 2171-2180)
- Word-based chunking in fallback provides reasonable streaming simulation

There was a problem hiding this comment.
Fix tool call argument parsing for proper execution.
The tool call arguments are passed as a string to execute_tool, but this method expects a dictionary of parsed arguments.
Apply this fix to properly parse the JSON arguments:
try:
- tool_result = self.execute_tool(
- tool_call['function']['name'],
- tool_call['function']['arguments']
- )
+ import json
+ parsed_args = json.loads(tool_call['function']['arguments']) if tool_call['function']['arguments'] else {}
+ tool_result = self.execute_tool(
+ tool_call['function']['name'],
+ parsed_args
+ )📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

🤖 Prompt for AI Agents
In src/praisonai-agents/praisonaiagents/agent/agent.py around lines 2143 to
2146, the tool call arguments are currently passed as a string to execute_tool,
but execute_tool expects a dictionary. Fix this by parsing the arguments string
as JSON before passing it to execute_tool, ensuring the arguments are properly
converted into a dictionary format.

when the stream=False, it should show the display_generation (even if there is streaming withint display_generation) then its fine. also verbose=True by default. so it should show the display_generation ❯ python basic-agents.py from praisonaiagents import Agent agent = Agent( agent.start("Why sky is Blue?") |

This fix modifies Agent._start_stream() to handle OpenAI-style models with direct streaming that bypasses the display_generation UI, allowing users to get raw streaming chunks when stream=True.
Key changes:
Fixes streaming behavior where chunks were wrapped in display_generation instead of being yielded directly to user code.
