USE CASES

Explore AI models with your own tasks

Try models from different providers, experiment with prompts, compare responses, and find the right solutions for your tasks. From coding and data analysis to prompt testing and cost optimization, EidoStack provides one workspace for experimenting with AI.

01 / EXPLORE AI MODELS

Try different AI models with your own tasks

Don't limit yourself to one model or one provider. EidoStack lets you work with supported models from OpenAI, Anthropic, and Google in one interface. Choose a model, send your own requests, and explore the results. When needed, compare several models at the same time.

Find the model that works best for your task

Instead of relying only on public rankings and demos, test model capabilities yourself.

?Test different models with the same requests.

?Compare response quality, style, and level of detail.

?Check how accurately models follow your instructions.

?Explore the characteristics and limitations of different models.

02 / NEW AI MODELS

Explore new AI models without switching between platforms

The AI industry moves fast. Providers regularly release new models with additional capabilities, improved quality, and different pricing. But reading about a new model's capabilities isn't enough to understand how useful it is. Try it yourself.

Discover how a new model differs from the one you already use

Open a newly supported model in EidoStack, send familiar prompts, and compare the results with other models. There's no need to switch between separate provider Playgrounds or manually move requests around.

?Try newly supported AI models.

?Compare new models with familiar ones.

?Explore differences in behavior and response quality.

03 / PROMPT EXPERIMENTATION

Experiment with prompts and improve AI responses

Even a small change to a prompt can significantly affect the result. Adding an instruction, changing the wording, or using a different system prompt can change how an AI model behaves. EidoStack lets you experiment with requests, repeat tests, and compare results in one workspace.

Find wording that works better for your tasks

Try different instructions and observe how the selected model's responses change. Use the same prompts with other models to explore differences in their behavior.

?Experiment with different prompt formulations.

?Create and modify system prompts.

?Test how accurately a model follows instructions.

04 / AI COST ANALYSIS

Compare the cost of different AI models

The cost of using AI depends not only on provider pricing but also on the number of tokens needed to complete a particular request. Two models can solve the same task while consuming different numbers of tokens and costing significantly different amounts. EidoStack helps you analyze these differences during real experiments.

Understand what your AI requests cost

Compare models on the same tasks and assess how their costs differ. Use built-in analytics to view token and cost statistics without constantly switching between provider dashboards.

?Track input and output tokens.

?View the estimated cost of every request.

?Compare costs across different models.

05 / MODEL COMPARISON

Find out whether you need a more powerful AI model

The most expensive model isn't always the best choice for a particular task. Some requests require complex reasoning and high accuracy, while faster and more affordable models can handle others very well. EidoStack lets you compare models from different tiers using your own tasks.

Find the right balance between quality and cost

Use the same prompt with different models and explore differences in their responses. Compare results, token usage, and estimated costs to understand when the benefits of a more expensive model really matter.

?Compare standard and premium models.

?Test complex and simple tasks across different models.

?Explore differences in response depth and quality.

OutcomeUse more powerful models where their capabilities are truly needed, and avoid overpaying for simple tasks.

06 / CONTEXT MANAGEMENT

Experiment with context and manage conversation history

Context affects what information an AI model receives and how it generates responses. But sending the entire conversation history isn't always necessary. EidoStack lets you choose different context-building strategies and analyze how they affect model behavior, token usage, and cost.

Find the right context strategy

Try different ways of passing conversation history and compare results. Use context window visualization to understand how many tokens the information you send consumes.

?Use the full conversation history.

?Send only recent messages.

?Include system instructions without conversation history.

?Use semantic search for relevant context through RAG.

07 / DEVELOPER TASKS

Use different AI models for coding and technical tasks

AI models can help developers write code, find errors, explain complex concepts, and solve engineering problems. But different models have different strengths. EidoStack lets you work with multiple AI models through one interface, use them for real development tasks, and compare the solutions they produce.

Find the AI model that handles your task best

Use the Playground as a workspace for experimenting with code, technical questions, and different approaches to solving problems. When needed, send the same request to multiple models and explore the suggested solutions.

?Code generation. Ask different models to create functions, components, and implementation examples.

?Code analysis. Review existing code and get suggestions for improvements.

?Error detection. Use AI to analyze potential issues and explain their causes.
