Read all four model reports
Grok · Los Angeles Rams · 56.0%
Rams enter at 2-2 hosting a 3-1 Bills team and are favored by 3.5 points on the provided market line. The spread implies a modest home-edge advantage that outweighs the one-game difference in record at this early point in the 2026 season. No contradictory facts appear in the package.
xai/grok-4.3 · Oct 12, 3:15 PM PDTGemini · Los Angeles Rams · 64.0%
The Los Angeles Rams are favored by 3.5 points at home against the Buffalo Bills. A -3.5 point spread typically translates to an implied win probability of around 63-65% for the favorite, outweighing the Bills' slightly better early-season record.
google/gemini-3.1-pro-preview · Oct 12, 3:15 PM PDTClaude · Los Angeles Rams · 64.0%
The only direct comparative signal is the DraftKings line of LAR -3.5 at home with a 55.5 total. A 3.5-point home favorite historically wins roughly 62-67% of the time; the high total slightly compresses the edge by increasing variance. Buffalo's better record (3-1 vs 2-2) is already embedded in the market price, and records at week 5 are noisy and strength-of-schedule unadjusted, so I do not override the line. I anchor on the market and settle near 64% for Los Angeles, a modest step toward even to respect the thin supporting evidence and absence of injury/QB confirmation.
anthropic/claude-opus-5 · Oct 12, 3:15 PM PDTGPT · Los Angeles Rams · 61.0%
The strongest comparative evidence in the package is the market spread: the Rams are listed as 3.5-point home favorites at SoFi Stadium. In NFL pricing, a favorite of that size generally implies a clear but not overwhelming win probability, typically around the low-60s. The Bills’ better record (3-1 vs. 2-2) is a counterweight, but records this early in the season are weaker evidence than a current market line that aggregates broad information. With no usable quarterback, injury, or weather adjustments supplied, the best evidence-bounded estimate is that Los Angeles wins somewhat more often than not.
openai/gpt-5.4 · Oct 12, 3:15 PM PDTWhat remains uncertain
- No injury or quarterback details supplied
- Moneyline odds absent; spread is only pricing signal
- Weather and travel factors not reported
- No moneyline odds are provided, requiring an estimation based on the point spread.
- No injury information is available, which could significantly impact the matchup.
- No moneyline odds supplied; probability inferred from spread conversion
- Injury lists are empty for both teams, likely incomplete rather than genuinely clean
- No quarterback status or depth-chart confirmation
