, context actually is every little thing. The standard of an LLM’s output is tightly linked to the standard and quantity of knowledge you present. In observe, many real-world use circumstances include huge contexts: code era over massive codebases, querying complicated data techniques, and even lengthy, meandering chats whereas researching the right vacation vacation spot (we’ve all been there).
Sadly, LLMs can solely work effectively with a restricted quantity of context. And this isn’t simply concerning the onerous limits of the context window, particularly now that frontier fashions help a whole lot of 1000’s, and even hundreds of thousands, of tokens. And people limits are persevering with to develop. The larger problem is a phenomenon referred to as context rot, the place mannequin efficiency degrades because the context size will increase.
This impact is clearly demonstrated within the paper “RULER: What’s the Actual Context Dimension of Your Lengthy-Context Language Fashions?” by Hsieh et al. The authors introduce RULER, a brand new benchmark for evaluating long-context efficiency, and take a look at a variety of fashions. The outcomes present a constant sample: as context size grows, efficiency drops considerably throughout all fashions. In lots of circumstances, the efficient context size (the place efficiency stays similar to Llama 2–7B) is simply round 50% of the marketed context window, and even much less.

Of their current paper “Recursive Language Fashions”, Zhang et al. suggest a promising method to tackling the context rot drawback. On this article, I’d prefer to take a more in-depth take a look at this concept and discover the way it works in observe, leveraging DSPy’s not too long ago added help for this inference technique.
Recursive Language Fashions
Recursive Language Fashions (RLMs) have been launched to handle efficiency degradation as context size grows, and to allow LLMs to work with very massive contexts (as much as two orders of magnitude past the mannequin’s native context window). That is turning into more and more vital as we undertake LLMs for duties that contain processing a whole lot of hundreds of thousands of tokens.
There are already a number of approaches for dealing with long-horizon duties. The most typical one (one thing you’ve most likely encountered when utilizing code brokers like Cursor) is context summarisation. On this setup, the dialog or working context is repeatedly summarised as soon as it approaches the mannequin’s context restrict. In observe, nevertheless, this typically falls quick: vital particulars and refined nuances from earlier steps are likely to get misplaced because the mannequin “forgets” outdated data to make room for brand new tokens.
Recursive Language Fashions take a unique, and surprisingly elegant, method. As a substitute of passing the whole immediate to the LLM every time, the immediate is handled as a set of variables obtainable in a Python REPL (Learn–Eval–Print Loop) atmosphere. The mannequin is supplied with instruments that permit it to examine these variables or recursively invoke itself on programmatically chosen fragments.

In different phrases, RLMs encourage the LLM to jot down code that constructs its personal sub-tasks, after which resolve these sub-tasks by recursively calling itself. This shifts the burden from squeezing every little thing right into a single immediate to structuring the issue in a method that the mannequin can navigate massive contexts extra reliably.
The authors evaluated their method throughout a number of long-horizon duties, the place RLMs delivered robust outcomes on each GPT-5 and Qwen-3 fashions.

The outcomes look extraordinarily promising. RLMs (with or with out subcalls) persistently outperform different approaches throughout all duties. Let’s see how this works in observe.
Utilizing RLM in observe
One widespread situation the place lengthy context actually shines is answering questions over a big data base. In order that’s precisely what we’ll attempt right here. I took all of the articles I’ve printed on In the direction of Information Science and loaded them right into a single Markdown file. Considerably surprisingly, that provides as much as nearly 1.5 MB of textual content. Hopefully, that’s sufficient for the mannequin to dig via.
Thankfully, DSPy has not too long ago launched an implementation of the Recursive Language Fashions inference method. This implies we don’t have to construct something ourselves; we simply want DSPy model 3.1.2 or newer.
pip set up dspy --upgrade
Let’s begin by loading the dataset.
with open('articles.md', 'r') as f:
articles = f.learn()
Subsequent, let’s verify what number of tokens it accommodates.
import anthropic
shopper = anthropic.Anthropic(api_key=config['ANTHROPIC_API_KEY'])
# Depend tokens for messages
token_count = shopper.messages.count_tokens(
mannequin="claude-sonnet-4-5",
messages=[
{"role": "user", "content": articles}
]
)
print(f"Enter tokens: {token_count.input_tokens}")
# Enter tokens: 386768
There are nearly 400K tokens in our context. Claude Sonnet 4.5 helps a 200K context window, so processing the whole dataset in a single immediate isn’t possible. That is precisely the place RLM turns into helpful.
To make use of DSPy, we first have to configure the language mannequin. As mentioned earlier, RLM depends on code to work together with the immediate, so it really works greatest with fashions which have robust coding capabilities. For that reason, I’ll use Claude on this instance, because it’s identified to carry out nicely on code-related duties.
lm = dspy.LM('anthropic/claude-sonnet-4-5', api_key=config['ANTHROPIC_API_KEY'])
dspy.configure(lm=lm)
Subsequent, we initialise the RLM by specifying its signature. On this use case, I move the complete set of articles together with a query, and anticipate the mannequin to extract key developments and return them as a listing of strings.
rlm = dspy.RLM('articles, query -> developments: checklist[str]')
Right here, I exploit Claude Sonnet 4.5 for each the principle mannequin and the recursive sub-calls. DSPy additionally lets you use a smaller mannequin for sub-calls by way of the
sub_lmparameter, which can assist scale back prices.
Now we will execute the RLM and entry the developments subject within the output.
output = rlm(
articles = articles,
query = '''What have been the principle AI developments of 2025 primarily based on offered
articles? Take note of the content material not solely the titles.'''
)
print('n'.be part of(output.developments))
# Agentic AI and Autonomous Techniques: Self-reflection patterns, iterative enchancment via suggestions loops (Self-Refine, Reflexion, CRITIC), and LLMs as reasoning engines that may autonomously plan and execute duties

The execution took round three minutes, and the outcome was a surprisingly believable abstract of the principle themes throughout my articles. Nonetheless, we’re not right here to be taught concerning the developments themselves. The extra fascinating query is how RLM managed to do that within the first place. So let’s dig deeper.
RLM below the hood
Naturally, essentially the most fascinating half is knowing what’s really taking place below the hood.
RLM implementation
As mentioned earlier, the important thing thought behind Recursive Language Fashions is that lengthy contexts are handled as a part of an exterior atmosphere, somewhat than being fed immediately into the mannequin as a single immediate. As a substitute, the LLM writes Python code to programmatically examine, decompose, and recursively invoke sub-LLMs over smaller snippets of the information.
At a excessive stage, the implementation has a number of core traits:
- It makes use of a sandboxed Python REPL (Learn–Eval–Print Loop) that permits the LLM to discover massive contexts via code execution.
- The LLM operates in a well-known agentic loop: it writes Python code, observes the output, after which decides what to do subsequent.
- It will possibly carry out recursive sub-calls (successfully calling itself) utilizing instruments like
llm_query()andllm_query_batched()to analyse smaller chunks semantically. - As soon as the mannequin is glad with the outcome, it finalises the method by calling
SUBMIT()with the output.
Prompts
To essentially perceive how this works, I discover it useful to examine the precise messages despatched to and from the LLM. DSPy makes this straightforward with the next command.
# Examine the uncooked LLM calls - exhibits the precise prompts despatched to the mannequin
dspy.inspect_history(n=39)
This offers us full visibility into what was shared with the mannequin at every step.
Let’s begin with the system message. It defines the enter variables obtainable to the mannequin (as specified within the RLM signature) and lists the capabilities the mannequin can name, similar to print, recursive LLM calls, and customary library utilities.
Notably, the RLM module additionally lets you expose customized capabilities to the Python REPL by way of the
instrumentsparameter when initialising the RLM. On this instance, I solely relied on the default capabilities, however in additional superior setups this is usually a highly effective extension level.
Your enter fields are:
1. `variables_info` (str): Metadata concerning the variables obtainable within the REPL
2. `repl_history` (REPLHistory): Earlier REPL code executions and their outputs
3. `iteration` (str): Present iteration quantity (1-indexed) out of max_iterations
Your output fields are:
1. `reasoning` (str): Assume step-by-step: what have you learnt? What stays? Plan your subsequent motion.
2. `code` (str): Python code to execute.
All interactions can be structured within the following method, with the suitable values stuffed in.
[[ ## variables_info ## ]]
{variables_info}
[[ ## repl_history ## ]]
{repl_history}
[[ ## iteration ## ]]
{iteration}
[[ ## reasoning ## ]]
{reasoning}
[[ ## code ## ]]
{code}
[[ ## completed ## ]]
In adhering to this construction, your goal is:
Given the fields `articles`, `query`, produce the fields `developments`.
You might be tasked with producing the next outputs given the inputs `articles`, `query`:
- {developments} # notice: the worth you produce should adhere to the JSON schema: {"sort": "array", "gadgets": {"sort": "string"}}
You might have entry to a Python REPL atmosphere. Write Python code and it will likely be executed. You will note the output, then write extra code primarily based on what you realized. That is an iterative course of.
Out there:
- Variables: `articles`, `query` (your enter knowledge)
- `llm_query(immediate)` - question a sub-LLM (~500K char capability) for semantic evaluation
- `llm_query_batched(prompts)` - question a number of prompts concurrently (a lot quicker for a number of queries)
- `print()` - ALWAYS print to see outcomes
- `SUBMIT(developments)` - submit closing output when carried out
- Customary libraries: re, json, collections, math, and so on.
IMPORTANT: That is ITERATIVE. Every code block you write will execute, you will see the output, you then determine what to do subsequent. Do NOT attempt to resolve every little thing in a single step.
1. EXPLORE FIRST - Have a look at your knowledge earlier than processing it. Print samples, verify varieties/lengths, perceive the construction.
2. ITERATE - Write small code snippets, observe outputs, then determine subsequent steps. State persists between iterations.
3. VERIFY BEFORE SUBMITTING - If outcomes appear improper (zeros, empty, surprising), rethink your method.
4. USE llm_query FOR SEMANTICS - String matching finds WHERE issues are; llm_query understands WHAT issues imply.
5. MINIMIZE RETYPING (INPUTS & OUTPUTS) - When values are lengthy, exact, or error-prone (IDs, numbers, code, quotes), re-access them by way of variables and parse/compute in code as a substitute of retyping. Use small, focused prints to sanity-check, however keep away from guide copying when variables can carry the precise worth.
6. SUBMIT ONLY AFTER SEEING OUTPUTS - SUBMIT ends the present run instantly. If you should examine printed output, run it in a single step, overview the outcome, then name SUBMIT in a later step.
You might have max 50 sub-LLM calls. When carried out, name SUBMIT() along with your output.
Let’s additionally check out the primary consumer message despatched to the LLM. This offers the mannequin an summary of the enter variables: their varieties, lengths (so the mannequin is aware of how a lot it may learn without delay), and a preview of the content material to know the construction.
[[ ## variables_info ## ]]

Reply with the corresponding output fields, beginning with the sector `[[ ## reasoning ## ]]`, then `[[ ## code ## ]]`, after which ending with the marker for `[[ ## completed ## ]]`.
Right here’s the mannequin’s preliminary response consistent with the format specified within the consumer message.
[[ ## reasoning ## ]]
I want to investigate articles to establish essential AI developments of 2025. Let me begin by exploring the information:
1. First, I am going to study the construction and content material of the `articles` variable to know what I am working with
2. I am going to want to take a look at a number of articles, not simply titles, to know the precise content material
3. Then I am going to use semantic evaluation (llm_query) to extract and establish developments
4. Lastly, I am going to compile the developments into a listing
Let me begin by exploring the articles knowledge to see its construction and get a way of what is obtainable.
[[ ## code ## ]]
# First, let's perceive the construction of the articles
print("Sort of articles:", sort(articles))
print("nLength of articles:", len(articles))
print("n" + "="*80)
print("First 2000 characters:")
print(articles[:2000])
print("n" + "="*80)
# Let's have a look at if we will establish the construction - seems like articles are separated
# Let's attempt to cut up and depend them
article_separator = "---ntitle:"
article_parts = articles.cut up(article_separator)
print(f"nNumber of article elements discovered: {len(article_parts)}")
print(f"First half size: {len(article_parts[0])} (doubtless empty or header)")
print(f"Second half size: {len(article_parts[1]) if len(article_parts) > 1 else 0}")
[[ ## completed ## ]]
The uncooked logs gave us a stable understanding of how the LLM interacts with the atmosphere below the hood. Subsequent, let’s study the trajectory the LLM adopted to achieve its closing output.
Trajectory
For a structured view of the trajectory, we will examine output.trajectory. This offers entry to every step of the mannequin’s reasoning, the code it generates, and the ensuing outputs. Basically, it offers a complete view of all REPL interactions.
# Look at the complete trajectory - this exhibits all REPL interactions
for i, step in enumerate(output.trajectory):
print(f"n{'='*60}")
print(f"STEP {i+1}")
print(f"{'='*60}")
print(f"n📝 REASONING:n{step['reasoning']}")
print(f"n💻 CODE:n{step['code']}")
print(f"n📤 OUTPUT:n{step['output'][:1000]}{'...' if len(step['output']) > 1000 else ''}")
It’s also possible to discover the complete go online GitHub.
Reviewing the trajectory helps us perceive the principle patterns the LLM makes use of to unravel the issue. On this case, it took 13 steps to achieve the ultimate reply.
Step one, as anticipated, was exploring the articles variable: analyzing its construction and getting a way of the obtainable knowledge. This preliminary exploration units the stage for all subsequent reasoning and sub-calls.
# First, let's perceive the construction of the articles
print("Sort of articles:", sort(articles))
print("nLength of articles:", len(articles))
print("n" + "="*80)
print("First 2000 characters:")
print(articles[:2000])
print("n" + "="*80)
# Let's have a look at if we will establish the construction - seems like articles are separated
# Let's attempt to cut up and depend them
article_separator = "---ntitle:"
article_parts = articles.cut up(article_separator)
print(f"nNumber of article elements discovered: {len(article_parts)}")
print(f"First half size: {len(article_parts[0])} (doubtless empty or header)")
print(f"Second half size: {len(article_parts[1]) if len(article_parts) > 1 else 0}")
Subsequent, the LLM realised that there have been 40 articles in whole, every separated by ---ntitle:, and that each article contained metadata fields like title, date, class, read_time, and url, adopted by the principle content material. Simply figuring out this construction from a 1.5 MB textual content file is already a major achievement.
Constructing on this understanding, the LLM then parsed the articles and generated a abstract of the article titles and essential themes.
# Parse articles into structured format
import re
# Break up by the article separator
raw_articles = articles.cut up("---ntitle:")
# Course of every article (skip the primary empty ingredient)
parsed_articles = []
for i, raw_article in enumerate(raw_articles[1:], 1): # Skip first empty ingredient
# Add again the "title:" that was eliminated by cut up
raw_article = "title:" + raw_article
# Extract metadata utilizing regex
title_match = re.search(r'title:s*"([^"]*)"', raw_article)
date_match = re.search(r'date:s*"([^"]*)"', raw_article)
category_match = re.search(r'class:s*"([^"]*)"', raw_article)
# Discover the place content material begins (after the second "---")
content_start = raw_article.discover("---", 10) # Skip the primary half
content material = raw_article[content_start+3:].strip() if content_start != -1 else ""
parsed_articles.append({
'index': i,
'title': title_match.group(1) if title_match else "Unknown",
'date': date_match.group(1) if date_match else "Unknown",
'class': category_match.group(1) if category_match else "Unknown",
'content material': content material,
'content_length': len(content material)
})
print(f"Efficiently parsed {len(parsed_articles)} articlesn")
print("="*80)
print("Pattern of articles (titles and classes):")
print("="*80)
for i, article in enumerate(parsed_articles[:10], 1):
print(f"{i}. [{article['category']}] {article['title']}")
print(f" Content material size: {article['content_length']} chars")
print()
After parsing the articles, the LLM determined to focus solely on AI-related content material, because the query particularly requested about AI developments.
# Let's give attention to AI-related articles (AI, Agentic AI, LLM Functions, ChatGPT classes)
# and pattern strategically to know content-based developments
ai_related = [a for a in parsed_articles if a['category'] in [
'Artificial Intelligence', 'Agentic AI', 'LLM Applications', 'ChatGPT', 'Deep Learning'
]]
Subsequent, the LLM recognized the important thing articles it wished to give attention to. It was a subjective choice primarily based on relevance and content material. To analyse these intimately, it used recursive sub-calls, processing every article programmatically.
To handle the workload effectively, the LLM cut up the articles into two batches and processed them sequentially. For every article, it additionally truncated the content material to the primary 15K characters. This technique allowed the mannequin to deal with a big quantity of textual content with out exceeding its context window, whereas nonetheless capturing crucial insights from every article.
# Create prompts to extract AI developments from article content material
# I am going to embrace a considerable portion of every article's content material for evaluation
prompts_batch1 = []
for i, article in enumerate(selected_for_analysis[:8]): # First batch of 8
# Take first ~15K chars of content material to remain inside LLM limits whereas getting substance
content_sample = article['content'][:15000]
immediate = f"""Analyze this text about AI from 2025 and establish the principle AI developments, applied sciences, methodologies, or ideas it discusses.

prompts_batch1.append(immediate)
print(f"Created {len(prompts_batch1)} prompts for first batch")
print("nProcessing first batch of articles...")
# Question the primary batch
results_batch1 = llm_query_batched(prompts_batch1)
print(f"nReceived {len(results_batch1)} outcomes")
print("nResults from first batch:")
print("="*80)
for i, (article, outcome) in enumerate(zip(selected_for_analysis[:8], results_batch1), 1):
print(f"n{i}. {article['title']}")
print("-"*80)
print(outcome)
print()
Lastly, the LLM reviewed the complete checklist of articles as soon as extra, recognized further related subjects, and processed them utilizing recursive sub-calls in the identical method. As soon as all the knowledge had been retrieved, it synthesised the outcomes into the trends_2025 variable (a listing of strings representing the principle AI developments) and submitted it as the ultimate reply.

# Submit the ultimate checklist of AI developments from 2025
SUBMIT(trends_2025)
We will see that the mannequin was fairly inventive: it understood the construction of our content material, parsed the articles, and used recursive calls to course of every one individually. Nonetheless, there was one vital hole on this evaluation. It fully neglected filtering by yr, though the metadata for every article clearly contained the publication date.
To deal with this, I repeated the request, this time emphasising the significance of filtering for 2025, to make sure the mannequin centered solely on articles from that yr.
output2 = rlm(
articles = articles,
query = '''What have been the principle AI developments of 2025 primarily based on offered
articles? Take note of the content material not solely the titles.
Do not forget to filter by yr, this data is current in
metadata for every article.'''
)
This time, the mannequin thought of the yr and carried out extra refined parsing, utilizing common expressions to extract the publication date for every article.
import re
from datetime import datetime
# Break up articles by the separator "---" initially of metadata blocks
# The sample is: --- adopted by metadata, adopted by --- adopted by content material
article_blocks = re.cut up(r'n---n', articles)
print(f"Whole article blocks discovered: {len(article_blocks)}")
print("n" + "="*80)
# Let's study the construction - articles appear to begin with "---ntitle:"
# Let me attempt a unique method - discover all articles by their metadata sample
article_pattern = r'---ntitle: "(.*?)"ndate: "(.*?)"ncategory: "(.*?)"nread_time: "(.*?)"nurl: "(.*?)"n---n(.*?)(?=n---ntitle:|$)'
matches = re.findall(article_pattern, articles, re.DOTALL)
print(f"Articles discovered with regex: {len(matches)}")
if len(matches) > 0:
print("nFirst article metadata:")
print(f" Title: {matches[0][0]}")
print(f" Date: {matches[0][1]}")
print(f" Class: {matches[0][2]}")
print(f" Content material preview (first 200 chars): {matches[0][5][:200]}")
Subsequent, it filtered the articles by yr and recognized 13 articles from 2025.
# Parse articles and filter for 2025
articles_2025 = []
for match in matches:
title, date_str, class, read_time, url, content material = match
# Extract yr from date string (format: "2025-10-24T12:00:00-05:00")
yr = date_str.cut up('-')[0]
if yr == "2025":
articles_2025.append({
'title': title,
'date': date_str,
'class': class,
'content material': content material.strip()
})
print(f"Whole articles: {len(matches)}")
print(f"Articles from 2025: {len(articles_2025)}")
print("n" + "="*80)
print("2025 Articles:")
print("="*80)
for i, article in enumerate(articles_2025, 1):
print(f"n{i}. {article['title']}")
print(f" Date: {article['date']}")
print(f" Class: {article['category']}")
print(f" Content material size: {len(article['content'])} chars")
Then, it analysed these 13 articles utilizing recursive sub-calls and produced an up to date checklist of developments. This time, the duty was accomplished accurately. As with many different examples, it highlights the significance of asking clear, express questions and specifying the factors and actions we wish the mannequin to observe.

Abstract
It’s time to wrap issues up and mirror on what we’ve realized. On this article, we explored RLM (Recursive Language Fashions) — a brand new inference technique that permits LLMs to deal with contexts as much as two orders of magnitude bigger than their customary context window, whereas mitigating the context rot drawback.
I’m genuinely fascinated by this method. The paper proposes a easy but elegant technique of treating prompts as variables in a Python atmosphere, which jogs my memory of my favorite agentic framework, smolagents by HuggingFace. I consider this technique is particularly environment friendly as a result of LLMs have been skilled on a lot code that programming appears like a local language to them. Utilizing code because the interface for reasoning and recursion is each sensible and highly effective.
General, Recursive Language Fashions provide a sensible and stylish approach to push the boundaries of context size, making LLMs extra able to dealing with complicated, large-scale duties. Nonetheless, clear directions and considerate steerage are nonetheless key to getting the very best outcomes.
Thanks for studying. I hope this text was insightful. Keep in mind Einstein’s recommendation: “The vital factor is to not cease questioning. Curiosity has its personal motive for current.” Could your curiosity lead you to your subsequent nice perception.
