Evaluating the Trustworthiness of LLM Providers: My Experience

I did something similar but on a smaller scale. I found that using a local server for running tests, instead of AWS Lambda, cut my costs by about 25%. However, it did add some complexity and effort in terms of setup and maintenance.

I faced the same budget issue when I underestimated the API call costs in one of my projects. Switching to spot instances for my computation-heavy tasks helped shave off some dollars. Also, I noticed AWS Lambda can stack up unexpected expenses if not precisely managed. Having a cleanup routine for unused resources really helped me.

I did something similar with a smaller dataset of about 500 questions. I found Claude to be pretty consistent, but GPT-3 occasionally surprised me with off-the-mark answers. My main issue, though, was with systematically grading the responses – I ended up using a more subjective method and less automation since the nuances were tough to quantify with scripts alone.

I've also been assessing the trustworthiness of LLMs for a client project, but I used a slightly different approach. Instead of benchmarking existing answers, I generated a 'blind test' dataset where the questions had multiple acceptable answers. This helped factor in the nuanced nature of language models. Budget-wise, I hit around $250 using a combination of job batching and running queries during off-peak hours to reduce costs. Has anyone tried cost-optimization with queue systems for these tests?

I've also run some validation tests but on a smaller scale, using around 200 questions. I noticed Claude occasionally gave more nuanced answers despite being slightly less accurate in factual responses compared to GPT-3. Did you notice a similar pattern in your results?

Thanks for sharing! I’ve also tested a few LLMs but focused more on their context retention capabilities in multi-turn conversations. I used a combination of Azure Functions and local evaluation scripts, which helped me squeeze in more localized testing. My budget was around $250, which I managed to maintain by optimizing the prompt lengths to reduce costs on the call side. What prompt structures did you find most effective?

I've toyed around with a lighter version of this approach by lowering the number of test questions but focusing on a deeper analysis of each response. I used spaCy instead of nltk for semantic similarity checks and found it pretty insightful. Anyone else tried different NLP libraries for their validation scripts?

Interesting approach! How did you handle the cases where the models gave completely different answers but still semantically correct? I'm finding it challenging to aggregate results meaningfully when multiple answers are plausible.

I did a similar evaluation across several LLM providers, including GPT-3 and Cohere, focusing primarily on average latency and cost-effectiveness per call. I found OpenAI's models offered more consistent accuracy, but Cohere was more predictable in cost over a large volume due to better pricing tiers. How did you handle discrepancies in model behavior across different times of day? I noticed some performance variation which was quite puzzling.

Great initiative! I did something similar with GPT-3 and Claude, but instead of tailoring different prompts, I standardized a baseline prompt. It was interesting to see how they still interpreted the prompt differently. One thing I found helpful was using pandas for more extensive data analysis post-evaluation. It helped a lot in identifying systematic errors!

Have you thought about integrating a feedback loop from real-user interactions after deploying your models? It might help refine the performance metrics, as user behavior can highlight discrepancies that benchmarks might not capture. Also, did you encounter any latency issues with Lambda during high-frequency API calls?

I encountered similar issues related to API call costs. One way I tackled it was by pre-filtering questions that are unlikely to help distinguish between models. This cut down the number of necessary queries. Did you also face any challenges with your manual grading process being subjective or time-consuming, and how did you address that?

How did you decide on the 'correct' answer set? I'm in a similar boat evaluating LLMs, and defining ground truth can be tricky. Would love to know more about your approach to this, especially given the subjective nature of language responses!

Interesting approach! How did you handle discrepancies when the models returned different but arguably correct answers? I've noticed the same prompt can yield varying interpretations especially if it's a bit vague, and I’m curious if your scoring system accounted for that.

I did something similar a while ago with OpenAI’s API but on a smaller scale—around 500 questions. Instead of AWS Lambda, I used Google Cloud Functions since I was already familiar with their setup, and it combined well with the rest of my environment. The cost was slightly under my budget at around $150, but the biggest hurdle was scripting a reliable grading system. I ended up using both nltk and spaCy for evaluating the semantic similarity, which gave me more nuanced insights.

I've tried something similar but focused primarily on the API response time in addition to accuracy. I noticed some providers had significant delays under load. My setup used Google Cloud Functions, and I ran into unexpected costs too. Might consider leveraging spot instances next time for cheaper compute rates.

Interesting approach using AWS Lambda! Did you encounter any throttling issues with API calls? Also, I'm curious if you tried using any other serverless architectures. Personally, I've been experimenting with Google's Cloud Functions to reduce costs when running similar batch processes. For me, scalability and ease of integration have been key savings too.

Great approach! I'm intrigued by your use of manual grading in conjunction with an automated script. Could you elaborate on how you ensured the manual evaluations were unbiased? Did you have multiple people grade each response to compare scores?

Interesting approach with the vendor verifier! In my project, I faced similar budget overruns due to high API call frequencies. I ended up using Hugging Face's models via their Transformers library to reduce costs, as they offer some models that can be run locally for no API cost. It might not be suitable for everyone, but it’s worth considering if cost is an ongoing concern.

Interesting approach using AWS Lambda! I went for a different route by deploying a local server to avoid cloud costs, though this increased my initial setup time significantly. Your cost findings are helpful — I often underestimate API call expenses!

I've done something similar but on a smaller scale for internal testing. Instead of using AWS Lambda, I opted for a containerized setup using Docker on local servers. It helped keep the costs down a bit since we had some spare capacity. I faced issues with semantic similarity algorithms when answers were creatively correct but not matching the 'correct' set, and fine-tuning the NLP metrics was crucial. Anyone else tackle similar issues?

Interesting approach with using AWS Lambda. How did you find the response time affected by deploying on Lambda? In my experience, sometimes the cold starts can mess up the timing and consistency checks a bit. I'd be curious if you dealt with that or made tweaks to mitigate the issue.

This is a super useful insight! Have you thought about integrating more automated checks beyond nltk? Tools like BERTScore or ROUGE might offer deeper insights into semantic similarity. I'd be interested to hear if someone has tried those alongside manual grading.

Hey, I did something similar but on a smaller scale. I used only 200 questions and relied mostly on automation with some manual oversight. Ended up using Google's BERT to get a baseline I trust and then compared responses from other models. I managed to keep costs down to about $150 using a local server setup instead of AWS. However, I'm considering scaling up and your post has been really informative for that!

I have yet to dive as deep as you have, but I had a somewhat similar endeavor when figuring out the accuracy of some LLMs for our customer support system. We used a smaller set of 500 questions and focused more on the correctness of responses specific to our domain. Our tests echoed your experience with cost overruns, as we exceeded our initial estimates by about 50%. We considered using Google Colab for their free GPU usage to mitigate costs, but scaling was a hassle.

I've done something similar but on a much smaller scale. I ran about 100 questions through GPT-3 and used a simple Levenshtein distance calculation to measure correctness. It was cheaper than expected, only about $50, but I definitely see how things could scale up quickly cost-wise. The manual grading was tedious, though. Anyone know better automation methods?

I have a similar setup, but I used Google Cloud Functions instead of AWS Lambda. Found it slightly more cost-effective for my needs, especially since I integrated some custom logging. I also ran into a bit of cost creep—paid around $350 in the end due to a large number of retries needed for some cases where the API responses were inconsistent. How did you handle inconsistent response issues during your tests?

We tackled something like this last year where we also used nltk but paired it with a tf-idf model to understand not just semantic similarity but also the uniqueness of each response. This gave us an extra layer of insight into each model’s 'personality', if you will. I agree with you on costs — our initial costs ballooned partly because of unforeseen retry logic in our Lambda layer when calls failed.

I've dabbled in similar territory, trying to evaluate the subtleties between different LLM services. One tricky part I found was accounting for slight variations in language understanding between models. I used a weighted scoring system that accounted for partial correctness, but tuning those weights took forever. Did you run into any issues with subjective grading, and how did you handle it?

Interesting approach with the AWS Lambda! Have you considered trying out the new models from Google, like Gemini? They might have different accuracy benchmarks or cost structures that could be worth evaluating. Also, what specific metrics were you using to determine 'correctness'? I'd love some insights on that part.

Interesting approach using nltk for semantic similarity. I've been relying heavily on cosine similarity with TF-IDF vectors, but sometimes find it lacking for nuanced answers. Have you considered using advanced metrics like BERT-score? Also, curious how you handled response variability—were the differences significant across retries?

I've done something similar, but I used a different approach by integrating Google Cloud's AI tools for semantic analysis. The costs were a bit of a surprise for me too; I ended up around $250 with some optimization tweaks. Instead of relying purely on textual responses, I also analyzed response time and model drift over time, which added another layer of complexity but yielded interesting insights on the dependability of these models.

I recently did something similar with a few different models, but instead of manual grading, I used a combination of sentiment analysis and vector embeddings to evaluate the performances. I found using vector embeddings to compare semantic similarity quite effective, especially when dealing with a large dataset. It helped me reduce some costs related to manual reviews. Give it a shot if you can automate more on your end!

Interesting approach! I've been using GPT-4 for a project, and while its accuracy is generally great, the cost can be a bit of a bump. Did you find the semantic similarity evaluation using nltk to be better than manual grading? Also, how did you decide on the pre-defined 'correct' answer set? That seems like it could significantly influence results.

I've done something similar but focused more on the qualitative side, reviewing the consistency of tone and style in responses, especially for content creation tasks. I noticed OpenAI tends to do better with creativity, whereas Claude's responses felt more grounded in factual content. Did you notice any variability in these areas?

Hey, your method seems pretty solid! I’ve been using a blend of Azure Functions and Google Cloud for running similar evaluations. They’ve got some interesting pricing structures that can help reduce the cost per call. As for measuring accuracy, I found OpenAI's API to sometimes have discrepancies in responses depending on regional load balancing—something to keep an eye on!

I’ve had some luck using Hugging Face’s Transformers library to run local tests instead of always relying on API calls. It reduced my costs significantly since most of the popular models have decent local counterparts. Of course, it doesn't quite capture the exact provider configurations, but for some preliminary evaluations, it can be quite useful.

I've done something similar but on a smaller scale. I used around 500 questions and got pretty different results between providers. I noticed that fine-tuning GPT-3 parameters helped achieve better contextual understanding, especially with technical content. Cost was a challenge for me too; hitting unexpected API calls cost my project about $150 more than expected. I had to tweak my scripts to optimize API usage and batch requests wherever possible.

I’ve had similar experiences with cost estimation spiraling up! I was testing a few models myself and tried to control costs by pre-filtering questions to reduce API hits. It's a bit more manual but saves on those unexpected overages.

Great approach! I conducted a similar experiment but focused more on the latency and response time. Interestingly, I found that Anthropic's Claude was about 20% faster on average compared to GPT-3, although the accuracy occasionally wavered. I budgeted about $250 but ended up spending closer to $350, partly because I underestimated the number of retries needed for some requests.

How did you handle grading for subjective questions? I find sometimes the model's answers are technically correct but not quite what I was hoping for in terms of depth or usefulness. Curious about any specific criteria or scoring system you used for the manual grading part!

This is fascinating! Did you notice any significant differences in accuracy between the various models? Also, how did you determine your 'correct' answer set—did you generate it manually or use any tool to help? I'm exploring a semi-automated way to create a reliable benchmark dataset myself.
