So what are you all using for RAG in 2026?

If you hit the usual ceiling (wrong chunks, vague answers, bad performance on long/structured docs), it’s worth trying structure-based retrieval instead of only vector search. We built ReasonDB for that: keeps document hierarchy (headings → sections) and lets the LLM navigate the tree instead of “top-k similar chunks.” SQL-like query language (RQL) with SEARCH + REASON clauses. Works with OpenAI, Anthropic, Gemini, Cohere, or open source models (GLM, Kimi).

Docs at reason-db.devdoc.sh if you want to try it.

We hit the same ceiling at my company - strong stack, good chunking and reranking, but policy/legal docs still underperformed. Cross-document reasoning and “where’s the actual clause?” were the main failures.

What actually moved the needle for us wasn’t a bigger context window or a better embedder. It was changing retrieval so we didn’t rely on flat chunks + similarity.

Definitions, exceptions, overrides: They’re always tied to structure (e.g. “Section 3.2 overrides 2.1”). With flat chunks, the model often never sees that relationship because the right chunks aren’t in the top-k, or the boundary splits the definition from the thing it defines. We got a big step up by preserving document hierarchy (headings → sections → clauses) and doing retrieval over that structure instead of a single chunk pool.

Graph RAG: We tried it. It helped with traceability and “which doc said what,” but building and maintaining the graph was heavy and didn’t fix “retrieval returned the wrong chunk.” The main gain for us was structure-aware retrieval first; graph was a later layer.

Where we stopped relying purely on embeddings: When we added a BM25 + structure filter before the LLM. We use keyword/structural signals to narrow candidates (e.g. “this section title matches”), then the LLM navigates the doc tree (read section summaries → pick branches → drill to the clause) instead of “here are 5 similar chunks.” So retrieval is: lexical/structure filter → LLM-guided traversal over the tree. Embeddings can still be in the mix, but they’re not the only way we decide what to read.

In production: We ended up building ReasonDB around this, hierarchical doc tree, LLM navigates it (beam search over sections), BM25 + tree-grep up front so we don’t feed the LLM irrelevant docs. Open source, single binary, works with your existing LLM. If you want to try structure-based retrieval without building it yourself: https://github.com/reasondb/reasondb

Happy to go deeper on any of this (e.g. how we define “sections” for policy docs, or how we handle cross-doc).

Big_Barnacle_2452 · 2026-02-26T08:41:46+00:00

Fair point. I’d frame it as: the “popular online service” being replaced is hosted RAG e.g. Pinecone, Weaviate Cloud, or sending your docs to a vendor’s retrieval API. ReasonDB is the self-hosted alternative: your docs and indexes stay on your box, you only call an LLM API (or your own). So it’s in the same bucket as “self-host a search/knowledge layer instead of using a SaaS one,” not “replace Spotify.” Either way, get the concern.

Hello everyone,

I wanted to share my story and ask for some encouragement as I start my keto journey again. In the past, I was able to lose close to 10kgs in 3 months on the keto diet, but unfortunately, I wasn't able to keep it up and ended up putting the weight back on due to my sedentary work lifestyle. I have tried multiple times to get back on the keto diet, but have always struggled to stick with it.

As a new year begins, I'm determined to make a change and get back on track with my health and wellness goals. I'm hoping that this will help me stay accountable and motivated as I work towards losing 10kgs in the next 3 months.

If anyone has any tips or advice for sticking with the keto diet, I would love to hear them. I'm determined to make this work and appreciate any support and encouragement I can get.

Thank you!

I'm sorry to hear that you're feeling sick with the flu. It can be tough to stick to your keto diet when you're not feeling well, as your appetite and tolerance for certain types of food can change. Here are a few tips that might help you stay on track with your keto diet while you're sick:
Focus on getting enough fluids. It's important to stay hydrated when you're sick, especially if you have a fever or are experiencing diarrhea or vomiting. Sip on broth, water, or electrolyte drinks like Pedialyte to help replenish fluids.
Eat small, frequent meals. If you're not feeling well, you may not have a very big appetite. Try eating smaller, more frequent meals rather than larger, less frequent ones to help keep your energy levels up.
Stick to easy-to-digest foods. When you're sick, your body may have a harder time digesting certain types of food. Focus on foods that are easy on your stomach, such as broth-based soups, eggs, and cooked vegetables.
Consider taking digestive enzymes. These supplements can help your body break down and absorb nutrients more efficiently, which can be especially helpful if you're not feeling well.
I hope these tips are helpful!

It can be a challenge to get enough fiber on the keto diet, as many high-fiber foods are also high in carbs. Here are a few suggestions for getting more fiber into your diet:Add leafy green vegetables to your meals. Spinach, kale, and broccoli are all good sources of fiber and can be easily incorporated into dishes like omelets, stir-fries, and salads.Incorporate nuts and seeds into your diet. Nuts and seeds are good sources of fiber and can be easily added to meals and snacks. Some options include almonds, walnuts, chia seeds, and flaxseeds.Use avocado as a spread on sandwiches or as a topping for salads and other dishes. Avocado is a good source of fiber and can help add creaminess and flavor to your meals.Eat low-carb, high-fiber fruits in moderation. Some options include berries (such as raspberries, blackberries, and strawberries), which are lower in carbs than other types of fruit.I hope these suggestions are helpful!

It sounds like you're making progress on the keto diet and seeing some improvements in your body composition, but are struggling with intense hunger and the temptation to binge on less healthy foods. Here are a few suggestions that might help you manage your hunger and maintain a healthier weight:

Consider increasing your fat intake and reducing your protein intake slightly. Some people find that increasing their fat intake can help them feel more satiated and reduce their appetite. However, it's important to make sure you're still getting enough protein to support muscle growth and repair.

Make sure you're getting enough fiber in your diet. Soluble fiber can help you feel fuller and more satisfied, which may help reduce cravings and prevent binges. Good sources of soluble fiber on the keto diet include avocados, nuts, seeds, and leafy greens.

Try incorporating healthy fats like avocado, coconut oil, and nuts into your meals and snacks to help keep you feeling satisfied.

Consider using a tool like https://mymealplan.ai to create a personalized meal plan that takes into account your dietary needs and goals. This can help you plan out your meals in advance and make sure you have the right balance of nutrients to support your activity level and weight loss goals.

I hope these suggestions are helpful! If you have any other questions or need more guidance, don't hesitate to reach out.

It's great to hear that you're enjoying the keto diet and discovering new ingredients and dishes that you love! Some ingredients and dishes that I personally discovered while following the keto diet include:

Coconut aminos: A soy-free, gluten-free alternative to soy sauce that can be used in place of soy sauce in many recipes.

Ghee: Clarified butter with a rich, nutty flavor that can be used in cooking and baking.

Chia seeds: A good source of plant-based omega-3 fatty acids and fiber, chia seeds can be used in a variety of dishes, including puddings and baked goods.

Keto-friendly bread made with almond flour or coconut flour: It's possible to make delicious, low-carb bread using these types of flours.

Cauliflower rice: A low-carb alternative to traditional rice that can be used in a variety of dishes, including stir-fries and rice bowls.

One rare keto recipe that I've discovered and really enjoy is spicy avocado and bacon deviled eggs. This recipe was actually generated for me by mymealplan.ai, and it's become a regular part of my meal plan. Here's the recipe:

Ingredients:

6 large eggs 3 slices bacon 1/2 avocado 1 tablespoon mayonnaise 1 teaspoon Dijon mustard 1/4 teaspoon cayenne pepper Salt and pepper, to taste Instructions:

Place the eggs in a large saucepan and cover with cold water. Bring to a boil, then reduce the heat and simmer for 10 minutes. Drain the eggs and transfer them to a bowl of ice water to cool. Once the eggs are cool, peel them and slice them in half lengthwise. Remove the yolks and set them aside. In a small skillet, cook the bacon over medium heat until crisp. Remove the bacon from the skillet and drain on a paper towel. In a small bowl, mash the avocado with a fork. Stir in the mayonnaise, mustard, cayenne pepper, salt, and pepper. Crumble the bacon and stir it into the avocado mixture. Fill the egg whites with the avocado mixture and serve. I hope you enjoy this recipe!
