Bunshin Big Model 4.5 Turbo

What is the Bunshin Big Model 4.5 Turbo?

Wenshin Big Model 4.5 Turbo is the latest generation of big language model released by Baidu on April 25, 2025 at Create Developer Conference. As the flagship product of Wenshin Big Model family, its core features are "multi-modal, strong inference, low cost", and it realizes comprehensive upgrades in terms of performance, functionality, and cost, aiming to provide more efficient and cost-effective AI solutions for enterprises and individual developers. It aims to provide more efficient and economical AI solutions for enterprises and individual developers.

Wenshin Big Model 4.5 Turbo Main Features

1. Multimodal processing capability
   • cross-modal interaction: It supports mixed input and output of text, image, and speech, and realizes cross-modal information alignment and joint reasoning. For example, if a user uploads a medical image and inputs a question, the model can combine visual features with the medical knowledge base to generate a diagnostic suggestion.
   • Dynamic content generation: In scenarios such as video generation and graphic creation, the model can process multiple modal data simultaneously to generate structured content. For example, dynamic videos are generated based on textual descriptions entered by the user, and voice narration is automatically added.
2. Deep Reasoning and Logic Enhancement
   • Long Chain of Thought (CoT) Optimization: Supporting multi-step reasoning and reflection, it can disassemble complex problems into logical chains and dynamically adjust the path of reasoning. For example, in mathematical proof problems, the model can generate a complete derivation process and backtrack to correct it when contradictions are found.
   • Tool call and action chainThe model integrates code interpreter, database query, API call and other tools to realize the closed loop of "think-act". For example, if the user inputs "analyze a company's financial report and generate visual charts", the model can automatically call data analysis tools to generate interactive reports.
3. Low cost and high efficiency
   • Price Direct 80%: The price per million tokens input is as low as $0.8, and the output price is $3.2, which is only 40% of the similar model. e.g., when an enterprise processes 100 million tokens per day, the cost is reduced by 80% compared to its predecessor.
   • Training and Reasoning Performance Improvement: Through the joint optimization technique of flying paddle text core, the training throughput of text core 4.5 Turbo reaches 5.4 times of that of text core 4.5, and the inference throughput reaches 8 times, which significantly reduces the resource consumption.
4. "de-illusionization" ability
   • Content Accuracy ImprovementThrough the technical framework of self-feedback enhancement, based on the generation and evaluation feedback capability of the large model itself, the model iteration closed loop of "training-generation-feedback-enhancement" is realized, which significantly reduces the model illusion, and the ability of the model to comprehend and deal with complex tasks is greatly improved.

Wenxin Big Model 4.5 Turbo Usage Scenarios

1. Enterprise Applications
   • Intelligent Customer Service: Through the multimodal interaction capability, it supports users to consult questions in voice, text, pictures and other ways, and the model can quickly understand and give accurate replies.
   • data analysis: Integrated code interpreter and database query tools support business users to enter natural language commands directly to automatically generate data analysis reports and visualization charts.
   • content creation: Supports multimodal content generation such as graphic, video, audio, etc. It is suitable for content production in advertising, film and television, games and other industries.
2. Developer Tools
   • API Calls and Integration: Supports API calls through the Baidu Intelligent Cloud Thousand Sails Big Model Platform, allowing developers to quickly integrate modeling capabilities into their own applications.
   • Code generation and debuggingThe combination of Wensin Quick Code intelligent code assistant supports multi-modal programming, development tool invocation, application preview, and realizes end-to-end generation of "Requirements - Coding - Debugging - Verification".
3. Individual user scenarios
   • Learning and education: Support multi-step reasoning and solving of complex disciplinary problems, e.g., mathematical proofs, design of physics experiments, etc.
   • Life Helper: Supporting life scenarios such as travel planning, health counseling, legal counseling, etc., users can input their needs through natural language, and the model can disassemble the task and call relevant tools to complete it.
